Power cables with high-strength ethylene-propylene rubber insulation HEPR TOFLEX R

Power cables are designed for connection to devices and distribution devices with a rated alternating voltage of 1 kV and 3 kV with a frequency of 50 Hz.

Cables with copper conductors can be used in hazardous areas of classes 0, 1, 2 according to GOST IEC 60079-10-1.

TOFLEX P cables withstand elevated ambient temperatures, which allows them to be used at the facilities of metallurgical enterprises. The insulation of high-strength ethylene-propylene rubber ensures uninterrupted cable operation at operating conductor temperatures up to 90 ° С, with peak values ​​up to 130 ° С, and satisfies high values ​​of permissible current load, leaving a good margin of safety. In addition, EPR insulation provides short circuit resistance at temperatures up to 250 ° C.
