Introduction

Interfaces you can trustABB manufactures underground and submarine power cables up to the highest voltages available.

Furthermore, we produce associated joints, terminations and other accessories for all types of cables. The products are designed to work perfectly together. Thus, we know what we connect.

Experience you can rely onWe have extensive experience of cable projects all over the world, encompassing every aspect from planning to commis-sioning, including engineering, route surveys, cable-laying, installation and final testing. Very few manufacturers can point to such a long tradition in the high voltage field as ABB. We delivered our first electrical cable in 1883 and introduced triple-extruded XLPE cables around 1970. In the early 1970s we started to supply cables for over 100 kV and our first 245 kV XLPE cable was put into service in 1978. ABB has since then supplied more than 7,300 km of XLPE cables above 100 kV. Experience you can rely on.

Research and developmentABB has always been a pioneer in the high voltage field and we have many world’s first and world records among our references. But there are no shortcuts to success. Maintaining our position calls for innovative research and development, backed up by the wealth of know-how we have accumulated over the years. One of the driving forces for our R&D is to meet the new and constantly increasing

requirements from the power industry and a deregulated market. Today we aim to develop the solutions our custo-mers will need tomorrow.

State-of-the-art manufacturing linesExperience and state-of-the-art expertise go hand in hand for us. We have been manufacturing cables for over 120 years and have since the beginning been one of the leading producers. Our factories are among the most modern in the world and our advanced quality system leaves nothing to chance. Every cubic millimeter of the cable has to be perfect. We design and produce cables in accordance with internationally approved standards or/and according to our customers’ specifications.

This guide presents XLPE cables and systems for under-ground applications mainly.

Testing of XLPE cable systemsStandard routine tests, sample tests, type tests and after lay-ing tests are normally performed according to IEC-standards. Other international or national standards may be followed upon agreement between contractor and purchaser.

Routine tests of XLPE cables and accessories• PD-measurement test. • High-voltage test of main insulation • Electrical test of oversheath, if required • Visual inspection

Sample testsSample tests are carried out with a frequency according to applicable IEC standards.• Conductor examination• Electrical resistance of conductor • Check of dimensions• Capacitance test• Hot set test• Electrical tests

After laying tests• DC voltage test of oversheath• AC voltage test of main insulation

Installation of XLPE cable systemsInstallation of cable systems includes trenching, cable pul-ling, clamping of cable, cable splicing as well as mounting of accessories. High quality installation work performed by ABB certified field personnel is essential for achieving the low failure rates and reliability performance that is expected from modern underground transmission and distribution circuits. ABB has long and extensive experience from different types of cable installations including direct burial, duct, shaft, trough, tunnel and submarine installations, but also trenchless technolo-gies like directional drilling, pipe jacking and others.

ABB´s XLPE cable systems are designed to meet requirements in international and/or national standards. Some of these are listed below.

IEC XLPE cable systems specified according to IEC (International Electrotechnical Commission) are among many other standards accepted. IEC standards are conside-red to express an international consensus of opinion.

Some frequently used standards are:IEC 60228Conductors of insulated cables.

IEC 60287Electric cables - Calculation of the current rating.

IEC 60332Tests on electric cables under fire conditions.

IEC 60502Power cables with extruded insulation and their accesso-ries for rated voltage from 1 kV (U

m=1,2 kV) up to 30 kV

(Um=36 kV).

IEC 60840Power cables with extruded insulation and their accessories for rated voltage above 30 kV (U

m=36 kV) up to 150 kV

(Um=170 kV). Test methods and requirements.

IEC 60853Calculation of the cyclic and emergency current rating of cables.

IEC 61443Short-circuit temperature limits of electric cables with rated voltages above 30 kV (U

m=36 kV)

IEC 62067Power cables with extruded insulation and their accessories for rated voltage above 150 kV (U

m=170 kV) up to 500 kV

(Um=550 kV). Test methods and requirements.

CENELECIn Europe, cable standards are issued by CENELEC. (European Committee for Electrotechnical Standardization.) They are as a rule implementations of the IEC specifica-tions. Special features in design may occur depending on national conditions.

HD 620 Distribution cables with extruded insulation for rated volta-ges from 3.6/6 (7.2) kV up to and including 20.8/36 (42) kV.

HD 632 Power cables with extruded insulation and their acces-sories for rated voltage above 36 kV (U

m=42 kV) up to 150

kV (Um=170 kV). Part 1- General test requirements.

Part 1 is based on IEC 60840, and follows that standard closely.HD 632 is completed with a number of parts and subsec-tions for different cables intended to be used under special conditions which can vary nationally in Europe.

ICEAFor North America cables are often specified according to ICEA (Insulated Cable Engineers Association, Inc.)

S-97-682Standard for utility shielded power cables rated 5-46 kV.

S-108-720Standard for extruded insulated power cables rated above 46 through 345 kV.

Trefoil and flat formationThe three cables in a 3-phase circuit can be placed in different formations. Typical formations include trefoil (triangular) and flat formations. The choice depends on several factors like screen bonding method, conductor area and available space for installation.

Bonding of the metallic screensThe electric power losses in a cable circuit are dependent on the currents flowing in the metallic sheaths of the cables. Therefore, by reducing or eliminating the metallic sheath cur-rents through different methods of bonding, it is possible to incresase the load current carrying capacity (ampacity) of the cable circuit. The usual bonding methods are described below:

Both-ends bondingA system is both ends bonded if the arrangements are such that the cable sheaths provide path for circulating currents at normal conditions. This will cause losses in the screen, which reduce the cable current carrying capacity. These losses are smaller for cables in trefoil formation than in flat formation with separation.

Single-point bondingA system is single point bonded if the arrangements are such that the cable sheaths provide no path for the flow of circulat-ing currents or external fault currents. In such case, a voltage will be induced between screens of adjacent phases of the cable circuit and between screen and earth, but no current will flow. This induced voltage is proportional to the cable length and current. Single-point bonding can only be used for limited route lengths, but in general the accepted screen volt-age potential limits the length.

Cross-bondingA system is cross-bonded if the arrangements are such that the circuit provides electrically continuous sheath runs from earthed termination to earthed termination but with the sheaths so sectionalized and cross-connected in order to eliminate the sheath circulating currents. In such case, a volt-age will be induced in between screen and earth, but no significant current will flow. The maximum induced voltage will appear at the link boxes for cross-bonding. This method permits a cable current-carrying capacity as high as with sin-gle-point bonding but longer route lengths than the latter. It requires screen separation and additional link boxes.

The XLPE cable should at least have a conductor cross section adequate to meet the system requirements for power trans-mission capacity. The cost of energy losses can be reduced by using larger conductor.

Load losses in XLPE cables are primarily due to the ohmic loss-es in the conductor and the metallic screen. XLPE cables can be loaded continuously to a conductor temperature of 90°C.

The dielectric losses in the XLPE insulation system are present also at no load current and depend primarily on the magni-tude of the operating voltage.

Dielectric losses in XLPE cables are lower than for EPR and fluid-filled cables.

Continuous current ratings for three-core cables are given in Table 1 and for single-core cables in Tables 2-5. The continuous current ratings are calculated according to IEC 60287 series of standards and with the following conditions:- One multi-core cable or one three-phase group of single-core cables- Ground temperature 20°C- Ambient air temperature 35°C- Laying depth L 1.0 m - Distance “s” between cable axes laid in flat formation 70 mm + D

e

- Ground thermal resistivity 1.0 Km/W

Rating factors for single-core cables are given in Tables 6 to 14.

Overload capacityAs infrequently as possible, an XLPE-cable may be overloaded above 90°C and the conductor temperature may reach up to 105°C. Singular emergency overloads are not expected to produce any significant impact to the expected service life of the cable. However both occurrence and duration of these overloads should be kept at a minimum. Cyclic and emergency ratings can be calculated according to IEC publication 60853.

Short-circuit currentsDuring short circuit events the maximum allowable tempera-ture in conductor or screen/metallic sheath is determined by the adjoining insulation and sheath materials. This is specified in IEC 61443 “Short circuit temperature limits of electric cables with rated voltage above 30 kV (U

m=36 kV). The dynamic for-

ces between the conductors must be taken into account for cable installations.

610 x 0.95 x 0.95 x 0.93 x 0.84 x 0.85 = 365 A

Please note that use of rating factors gives good general indication during planning future circuits. Once a circuit layout is defined, an accurate calculation should be performed to confirm the assumptions.

ABB 13

Copper screens may reach a temperature of 250oC without damaging adjacent insulating material. With an initial tem-perature of 50oC this corresponds to a current density of 165 A/mm2 during 1s. (Both higher and lower current den-sities may be allowed if other conditions apply.)Lead sheath temperatures of up to 210oC are permitted in connection with short circuit events. With an initial tempe-rature of 50oC this corresponds to a current density of 28 A/mm2 during 1 s.

Maximum short circuit currents due to thermal restrictionsThe thermal energy developed during a short-circuit is determined by the short-circuit magnitude and duration. For design purposes, an equivalent short-circuit current with a duration of 1 sec is used according to formula below. This formula is valid for a short-circuit duration of 0.2 to 5.0 sec.

Ish= short-circuit current [kA] during time t

sh

I1

= short-circuit current rating during 1 second. See the 1 second value in Table 15 for the conductor and in Table 16 for the metal screen.

tsh= short-circuit duration (sec)

For XLPE insulated conductors the maximum allowable short circuit temperature is 250oC.

Dynamic forces during short circuit eventsIn addition to the thermal stresses, the dynamic forces in the cables and accessories during a short circuit event must also be considered. The dynamic effect of parallel conductors carrying cur-rent is responsible for the dynamic force.The dynamic force between two conductors, can be calcu-lated as:

Standards – IEC and ICEAConductors are manufactured according to the following standards:

IEC (International Electrotechnical Commission) Standard Publication 60228, Class 2: Stranded circular or shaped conductors of copper or aluminium. ICEA, Standard Publication No. S-97-682, further specified in ASTM B 400-18 for aluminium, ASTM B 496-81 for copper.

Conductor water sealingIf required, the conductor can be water sealed by:- Swelling material between the conductor strands. This material turns into jelly when in contact with water.- Filling compound between the conductor strands.

*SegmentedCuconductorincludingtapes

ABB 17

Copper wire screen, standard designA polymeric sheath covers the copper wire screen.

Metallicscreen

Copper wire screen, water tight designRadial water sealing is achieved by using a metal-PE laminate. The metal is normally aluminium. Copper may also be used. The laminate is bonded to the polyethylene, which gives excellent mechanical properties. Longitudinal water sealing is achieved by using a water swelling mate-rial at the copper wires or swelling powder between the screen wires.

Lead sheathRadial water sealing achieved by a corrosion resistant lead sheath. Longitudinal water sealing is achieved by using a water swelling material applied under the lead sheath.

Copper tape screenCross section defined by the geometrical cross section of the copper tapes.

I N S U L A T I O N | M E T A L L I C S C R E E N

XLPE insulationThe XLPE insulation is extruded simultaneously with the conductor screen and the insulation screen, e.g. triple extrusion. The interface surfaces between insulation and conductive screens are not exposed at any stage of the manufacturing. High quality material-handling systems, triple extrusion, dry curing and super-clean XLPE materials guarantee high quality products. The insulation thickness is determined by the design electrical stresses for AC or impulse. The actual thickness for different voltage levels and conductor sizes is given in Tables 23 to 39.

Insulation screenThis screen consists of an extruded layer firmly bonded to the XLPE insulation. The material is a high quality conductive compound. The interface between the screen and the insula-tion is smooth.

18 ABB

Non-metallicoutersheath

PE or PVC are normally used for the non-metallic outer sheath. IEC 60502 recommends a thickness of t = 0.035 x D + 1.0 mm, where D is the diameter under the sheath. For heavy installations a larger thickness is recommended. PE is the first choice for most applications. PVC is used when there are high requirements on fire retardation beha-viour.

Conductiveouterlayer

A conductive outer layer facilitates testing of the non-metallic outer sheath. This testing is important to ensure the physical integrity of the cable from time to time, either in factory, after transportation, directly after laying, upon completion of the installation, or periodically thereafter.A conductive outer layer obtained by simultaneous extrusi-on with the non-conductive outer sheath presents superior electrical and structural properties.

Flameretardantouterlayer

For PE-sheathed cables a halogen free and flame retardant layer can be applied in order to limit the fire spread in buildings and tunnel installations.

Firebehavior

This relates to cables in buildings and tunnels.

Several serious fire accidents have focused attention on the fire behaviour of cables. Experience shows that cables seldom initiate fires. However, in some cases cable instal-lations have influenced the extent of a fire, as a propagator of flames and or as a source of intense aggressive smoke.

Cables having a PVC sheath are considered as flame retar-dant. However, once PVC is on fire, it generates hydro-chloric acid fumes (HCl) acid. This gas is highly corrosive and irritating to inhale. Cables with a standard PE outer sheath do not generate any corrosive HCl but are not flame retardant. Special polyolefines with flame retardant properties but without chlorine or any other halogenes are optional for the outer sheath.
