Special Wire and Cable > Waterproof Cable
JHS Longitudinal Water-Blocking Cable (500V)
Designed to VG 95218 Part 29, the JHS Longitudinal Water-Blocking Cable blocks water radially through the sheath and completely along its length, with a dedicated water-blocking center unit adding an extra layer of protection at the cable core. A tinned copper braid overall shield and cross-linked halogen-free flame-retardant black sheath support vessel outboard installation and protected motor rotor connections up to 1000V. Available in 8 pre-configured core/cross-section options at 500V. Dual CE and UL certified, available for OEM/ODM production in custom core counts, lengths, and reel packaging.
