Overhead conductors

ACSR conductors

This is most popular group of bi-material conductors. Structure of conductor consists of a steel core which is part of the carrier and the aluminium wire stranded of the same diameter. The strength of the cable consists of mechanical properties of steel and aluminium, but the electrical characteristics are provided only by the aluminium layer.

Overhead conductors

AAC conductors

AAC conductors are made entirely of aluminium wires with aluminium content min. 99.5%, thus giving the possibility of obtaining the electrical conductivity of the order of 61% IACS. Strength properties of this conductors stem with aluminium wires property. Structure of the conductor is made of round wires of the same diameter twisted coaxially. AAC conductors are widely used in urban areas where spans are usually short but high conductivity is required. The permissible operating temperature of the conductor is +80°C.

Overhead conductors

AAAC conductors

In the AAAC conductors pure aluminium has been replaced by high-strength alloys based on aluminium (EN-AW 6101; EN-AW 6201 and others). The design of this group of conductors is analogous to the structure of the AAC. The consequence of the use of this alloys, is a high strength of wire and electrical conductivity of 57% IACS resulting from the use of AL2-AL8 wires. In addition, AAC conductors have a number of advantages, such as current carrying capacity higher than in case of ACSR, excellent corrosion resistance and the best weight-to-strength ratio among the wires. The permissible operating temperature of these conductors is +80°C.

Overhead conductors

We can design and make conductors for specific customer requirements of constructed overhead lines. NPA Skawina has in its portfolio of products conductors such groups as the AAC and AAAC conductors, ACSR conductors, low sag conductors and high temperature conductors.

Overhead conductors

How we can pack it for you?

Conductors are delivered in the agreed sections, wound on wooden drums or steel drums received from the client. Wooden drums are in line with the standard PN-91 / O-79353. Available outer diameter of drum: 1,000 to 2,800mm.

Flexible conductors

Application

NPA Skawina manufactures flexible conductors made of wires with diameters from 0.7mm to 0.3mm. Such conductors are used, among others in the production of electrical systems in cars, wind power plants, industrial machinery, household appliances and railways. Physical, mechanical and electrical properties make it possible to use this type of conductors in very broad range of application.

For the production of flexible cables NPA Skawina developed a special alloy wire rod named SkawDraw which guarantees high quality of manufactured cables. As a result, cable quality control takes place just at the level of the manufacture of wire rod - the material from which the wires are drawn. SkawDraw is based on EN-AW 1370 this material is a high purity alloy, where Al = 99.7%.
