Special Wire and Cable > Waterproof Cable
Water-Blocking Cable (500V)
This 500V water-blocking cable is engineered for continuous submersion, with multiple internal water-blocking tape and filler layers that stop water from migrating along the conductor even when fully immersed. A tinned copper braid overall shield and special elastomer insulation keep mechanical stability intact underwater, making it suitable for vessel outboard installation and protected motor rotor connections up to 1000V. Dual CE and UL certified, available for OEM/ODM production in custom core counts, lengths, and reel packaging.
Key Features
Engineered for full submersion, the water-blocking cable maintains stable insulation and mechanical performance even in continuous underwater and marine service.
Full Submersion Rated
Maintains stable insulation performance and mechanical stability even when fully submerged in water.
Water-Blocking Construction
Multiple internal water-blocking tape and filler layers stop water from migrating along the cable core.
Minimal Water Weight Gain
Engineered to minimize weight increase when submerged, easing handling and installation.
Tinned Copper Braid Shield
Overall tinned copper braid adds corrosion resistance and shielding for marine environments.
Protected High-Voltage Install
Suitable for motor rotor connection cables up to 1000V, protected fixed installation in conduit.
Dual Certified
CE and UL certification supports distribution across both EU and North American markets.
