Rubber insulated power conductors and cables

Cables for Rail Vehicles

MANUFACTURING PROGRAMME

FKS manifactures these cables in accordance to UIC 895/76, regulations, issued by the International Railway Union. In accordance with these regualitons, FKS manifactures and folowing types of elastomeric cables for rail vehicles:

- Low tension cables type ŽEpN/F 750 V,
- High tension cables type ŽepN/FV 1500 V,
- High tension cables type ŽEpN/FV 3000 V.

QUALITY OF MATERIALS

Quality of materials and all tests in laboratories of FKS are in accordance with standardUIC 895/76, category I, group A, type 1 i class 5 (very flexible conductors). Into these cables FKS builds a high quality insulation manufactured on the basis of ethylene - propylene elastomer, which overreaches the prescribed demands of UIC standard. Permanent allowed temperature of conductor for these cables in accordance to UICstandard is 60 °C, and the permanent allowed temperature of insulation FKS uses is 90 °C. Theat means, that these cables can endure much higher current loads than prescribed. Also into these cables FKS builda a high quality sheat manufactured on the basis of Polychloroprene (Neoprene) elastomer, which working temperature is 90 °C.

APPLICATION

These cables are aplied for locomotives and railway coach for electric traction enquines, electric circuits for heating of rail vehicles, electric circuits for control and steering as well as lighting of rail vehicles. FOr rail vehicles, trolley buses and other similar machines.

CABLES LAYING

Cables for rail vehicles may be layed in tubes, canals or freely in the air.
