Waterproof Power Cable

Waterproof power cables are special cables with both radial and longitudinal water-blocking capabilities, effectively preventing moisture from penetrating the conductor and insulation layer, thus avoiding short circuits or leakage caused by moisture. These cables are widely used in underground installations, tunnels, ports, hydroelectric power stations, garden lighting, photovoltaic projects, and other locations prone to water accumulation or prolonged dampness.

Product Feature And Application

Recommended Typical Application Scenarios

Temporary Power Supply for Construction Sites: JHS-3×6+1×4 specification is recommended, supporting equipment such as feeders, lighting, and water pumps, and can withstand short-term immersion operations.
Buried Wiring for Photovoltaic Projects: YJV22-4×25+1×16 is recommended, with armored structure to prevent rodent bites and corrosion, suitable for long-term burial.
Tunnel/Metro Lighting Systems: FS-YJV23 series is used, with longitudinal water-blocking function to prevent rainwater from spreading along the cable.
Agricultural Irrigation Systems: JHS type flexible cable is used to connect aerators and water pumps, adaptable to frequent movement and humid environments.

FAQ

What are the precautions for installing and maintaining waterproof power cables?

1. Never use plastic bags instead of waterproof tape: Cases have shown that wrapping cable joints with plastic bags caused water ingress and tripped the circuit breaker, posing a serious safety hazard.
2. Joints must be professionally sealed: Use heat shrink tubing + waterproof sealant to ensure a complete seal at the interface.
3. Regularly check the condition of the sheath: Replace it immediately if cracks or bulges are found to prevent internal moisture absorption.
4. Avoid prolonged exposure to direct sunlight: Ultraviolet rays accelerate rubber aging; it is recommended to install conduit for protection.
