Nexans SIWO-KUL® B20 3.3 / 4.2 kV
Nexans SIWO-KUL® B20 3.3 / 4.2 kV
Combining a flexible tinned copper conductor with silicone insulation, protected by a polyester braid with silicone coating, these flexible single-core cables offer excellent flexibility, high electrical reliability and high resistance to extreme temperatures. Their construction also ensures good resistance to mechanical stresses, oils and many chemical agents. They are particularly suitable for the connection of windings of rotating machines and transformers of thermal classes F and H, as well as motors, generators, converters and industrial equipment in the railway and marine sectors, subjected to repeated thermal cycles and demanding operating conditions.
