The GOE bushing is available in two designs: GOE and GOE(2). The bushing is built up around a centre tube on which the condenser core is wound. For bushings up to 550 kV paper of full width is employed. Bushings for higher voltages are wound from paper strips in a manner similar to that used for cables. The foils are located so that the best possible combination of external flashover and internal puncture strength is achieved.

The upper insulator, which is made in one piece without gaskets, the lower insulator and the mounting flange are held between the end plates by the centre tube and sealing is accomplished by oil-resistant rubber gaskets in grooves. The upper insulator is made of high quality electrical porcelain. Standard color is brown. Light grey porcelain is available on request.

For GOE 250 to 900 the top housing is equipped with two oil level gauges of prism type. For GOE 1050 and larger, the top housing is equipped with a magnetic oil level indicator.

The mounting flange is an aluminium alloy casting. The gasket surface is machined flat. On the flange there is a test tap. This tap is automatically earthed by a protective cap when the tap is not connected to external test or measuring circuits. The mounting flange and the top housing are shot blasted to obtain a thoroughly smooth surface finish. The mounting flange can be equipped with extensions on the oil side, providing space for current transformers.

The rated current is defined according to IEC 60137. It is valid only when the centre tube is used as conductor. For draw lead applications the permissible current will be lower. Please refer to the applicable section.

Bushings GOE 450 and larger require a shield at the oil end. The purpose of this shield is to avoid excessive electrical stresses in the oil at the lower end plate and at the connection between the insulated lead from the transformer winding and the draw lead or other conductors in the bushing. The maximum stresses in the oil at the surface of the shield insulation must be limited to those values normal for insulated conductors and similar components in the same transformer.

ABB manufactures shields of this type, which are quoted for and delivered separately. The shields are made of aluminium and are insulated with epoxy or a lining of pressboard. The shield may be mounted on the lower end plate of the bushing, or on the bottom contact of the draw rod. Dimensions and recommendations, see Figs. 18, 19 and 22-26.

It is of great importance that the shield is placed in the right position in order to protect the bottom end of the bushing. Guidelines for positioning of the shield are given in Figs. 24 and 26. ABB can also provide assistance with field calculations to confirm the performance of other shielding systems.

Quotations for modifications in design and additional parts such as special terminal studs, shields, rod gaps, etc., as well as special tests, are given on request.

3D models and dimension drawings can be downloaded from the ABB website.

GOE featuresA set of concentric tubes are pre stressed and serve as springs which hold the main bushing components together and provide adequate pressure on the gaskets in all expected temperature and load conditions. The annular space formed between the tubes makes an efficient cooling duct for dissipation of the heat, thus improving the current-carrying capacity and thermal stability of the bushing.

The bushing is designed to be mounted at an angle of up to 30° to 60° from the vertical. A higher inclination can be obtained on request. The current shall be reduced for horizontal mounting and up to 15° from horizontal.

The top housing is made of aluminium and has expansion space for the oil, sufficient for temperature variations in the bushing between -40° and +80 °C. Variations in the length of the centre tube and the housing are compensated by a flexible connection inside the top housing.

The upper insulator on bushings GOE 1050 and larger are equipped with retaining rings mounted with stainless steel details.

GOE(2) featuresA set of springs in the top housing provides adequate pressure on all gaskets, independently of temperature and load conditions.

The bushing is designed to be mounted at an angle not exceeding 30° from the vertical.

The top housing has expansion space for the oil sufficient for temperature variations in the bushing between -40° and +80 °C. Variations in the lenght of the centre tube are compensated by the flexible cover of the housing.

For GOE(2) the upper insulator is cemented to a flange which is bolted to the mounting flange.

Features and benefits• A complete range and outstanding operational experience

from the most demanding applications for more than 30 years.

• Our unique draw rod system facilitates easy field installation and removal without lowering the oil level.

• The worlds most used 800 kV bushing. Never any failures in the field.

• 3D models makes it easy to incorporate the bushing in its context.

• We use a sealing system proven since 40 years around the world.

• Our test criteria and margins exceeding international standards.

• Only extra long creepage shed profile.

Shed profileThe shed profile for all GOE bushings is of the alternating type, with alternating long and short sheds.

GOEThe shed profile is designed according to IEC 60815. For each pair of sheds, the ratio between nominal creepage distance and the axial length is 4.0. This shed profile is developed and tested specially for heavy pollution.

GOE(2)The shed profile is designed according to IEC 60815. For each pair of sheds, the ratio between nominal creepage distance and the axial length is 3.94.

During manufacture and on completion the bushing is subjected to a number of routine tests, according to IEC 60137 and IEEE bushing standards. However, ABB’s requirements for acceptance are generally higher than IEC and IEEE standards.

A tightness test is carried out on the assembled bushing after the final drying and impregnation. The test is made at an oil overpressure of 180 kPa (1.8 bar) for 12 hours at ambient temperature. No sign of leakage is allowed. Each bushing is subjected to a final electrical routine test. The test is made at room temperature with the lower end of the bushing submerged in oil. Capacitance and tan d are measured in steps up to the power frequency withstand voltage, which is maintained for one minute. The PD value must not exceed 30 pC at the withstand voltage. Capacitance, tan d and internal partial discharge are also measured with decreasing voltage at the same voltage levels as before the one minute test. It is always demonstrated that the PD value is below 5 pC at rated voltage (=√3 times bushing service voltage).

Requirements for tan d are max. 0.55 % for Um ≤ 362 kV, max. 0.5 % for Um between 362 and 550 kV and max. 0.4% for Um > 550 kV. These measurements are carried out at the same time, and at the same levels, as the tan d test.

Bushings with Um ≥ 245 kV are routine tested with a dry lightning impulse voltage withstand test, in addition to what has been described.

Type tests have been carried out according to IEC 60137 and IEEE. Type test reports are available on request.

Test tapAll GOE bushings are equipped with a test tap connected to the outer layer of the condenser core. The max. test voltage of the tap is 20 kV, 50 Hz for one minute. Max. service voltage is 6 kV.

In connection with an external capacitance the test tap can be used as a voltage tap. The test tap has dimensions according to IEEE Potential tap type A.

Test tap adapterFor permanent connection of the test tap to measuring circuits, a test tap adapter is required. Catalogue number 2769 522-C.

Oil sampling valveAll GOE bushings are equipped with an oil sampling valve. The oil sampling valve can also be used as connection to pressure sensor or pressure switch using the ISO-G 1/4” inside thread.

The rated currents specified in this catalogue are based on thermal tests and are in accordance with IEC 60137 and apply to the built-in conductors of the bushings. The GOE bushings conform to the requirements of IEC 60137 and IEEE for currents given in Table 11.

Short-time currentThe rated thermal short-time current (Ith), as defined in IEC 60137 clause 5, is listed in Table 11 for draw rod and fixed bottom end terminal.

For draw lead of stranded copper with the area 100 mm2 the short-time current (Ith) is 9.6 kA for 1 second and 6.8 kA for 2 seconds. For other areas the short-time current is directly proportional to the area. The rated dynamic current (Id) is 2.5 times the 1 second short-time current.

Overload capacity of bushingsIf the conductor for the bushing is selected with 120 % of the rated current of the transformer, the bushing is considered to be able to withstand overload conditions according to IEC 60076-7 without further clarification or tests. This recommendation complies with IEC 60137.

The oil side connection can be made with either a draw-rod system, a draw-lead system or a fixed bottom contact. For the air side connection the same outer terminals are provided for both systems. When ordering, please specify the items stated below.

Draw rod systemFig. 14: The centre tube of the bushing is used as current conductor.

Fig. 15: The transformer leads are fitted with cable lugs, which are bolted to a bottom contact.

Fig. 16: This contact is drawn against the lower end of the bushing tube by a thin steel draw rod.

Fig. 17: During installation on the transformer, the upper end of this rod is bolted to a spring device beneath the outer terminal, which consists of two concentric tubes of different materials and is so designed that it gives the required contact load at all temperatures.

Bottom contacts with 4 or 6 threaded holes for cable lugs are available. The bottom contacts are made of copper and have rounded edges, so that they may be used without any shield for low insulation levels (BIL <450 kV).

At the level of the flange the draw rod is split into two parts. If required to meet the transport conditions, a joint at any desired level below the flange can be offered on request. The lower part with contact end shield can then be secured to the cover during transport and storage of the transformer.

This system has been supplied by ABB since the seventies with an excellent service record and has the following advantages compared to other methods used for high currents:• No hand holes required in the transformer tank.• Easy bushing installation and removal – no connection

work inside the transformer at site.• No special supports required in the transformer as is the

case with plug contacts.• Perfect guiding of the bushing into the transformer.• The lower end shield may be fixed to the contact and will

thus be correctly positioned with respect to the lower end plate of the bushing.

• No mechanical forces exerted on the leads from the transformer windings at any time.

Draw lead system, GOESuitable copper terminals for flexible draw leads are available for currents up to 1600 A. The terminal system consists of a two-part cable connector with a hole for brazing of the cable or cables. The two parts are screwed together in such a manner that normal tolerances in the cable and bushing lengths can be compensated. The connector is fastened by a hexagon nut to a copper plate placed at the top of the bushing. The GOE outer terminal stud is placed on top of this plate.

—22 Fixed bottom contacts.

The fixed bottom contact system uses the center tube as a current conductor. The bottom contact is fastened to the bushing bottom nut with six M10 bolts.

For suitable end-shields, see Table 16.

Outer terminalThe outer terminal consists of a cylindrical stud. The mounting arrangements are the same for all GOE bushings, regardless of size, current rating and internal connection system. Copper and aluminium studs are available.

The terminal stud assembly consists of a stud, a retainer ring, a gasket, bolts and washers. The

electrical contact function and the sealing function are completely separated.

The stud is first fastened to the bushing top with M10 bolts, which give the proper electrical contact. The contact surface is located inside the gasket and is thus well protected from corrosion. Finally, the retainer ring with the gasket is pressed against the stud by means of M8 bolts.

The maximum stresses in the oil at the surface of the shield insulation and the parts surrounding the bushing must be limited to those values normal for insulated conductors and other similar components in the same transformer.

The withstand voltages in a specific case depend upon many factors beyond the control of the bushing manufacturer. Therefore the configurations and distances given below are only intended as guidelines.
