Rowe Industries' High-Voltage Cables come in a range of constructions and voltages. From 15 KVDC R5743-1 Cable all the way to 50 KVDC R1006-1 Cable, we have the high-voltage cable you need. Both our 15KVDC R5743-1 and 50 KVDC R1006-1 cables feature silver-coated copper conductors and tinned coated copper braid shields, but the rest of their construction and materials are different. The 20 KVDC R5234-1 Cable and 30 KVDC 2R1032-4 Coax have tin-coated copper conductors and tin-coated copper braids, but the 20 KVDC R5234-1 cable has Teflon® insulation and jacketing while the 30 KVDC 2R1032-4 Cable has silicone insulation and a protective fiberglass braid. Some of these high-voltage coaxial cables have relatively complex constructions, so be sure to review spec sheets for more information.
