Hardcore cable for hardcore applications

Cables under the most heavy conditions have one thing in common, they have to transmit power safely, permanently and absolutely free of interruptions. Particularly in critical applications where high mechanical stress, combined with sunlight, dirt and temperature play a major role, you need components you can rely on. Standard PVC, rubber or PUR cables withstand a tensile load of max. 20 kg - ROCKERFLEX® e.g. 3x1,5 mm² withstands up to 1,350 kg*.
