FS: Waterproof, YJ - Cross-linked polyethylene insulation, V - Polyvinyl chloride sheath.
FS-YJV is a waterproof power cable. So what exactly is a waterproof cable? Waterproof cable primarily prevents water from entering the cable structure. Special waterproof materials are used in the cable sheath and insulation, making the cable waterproof and protecting it from damage. Waterproof cables generally achieve this through two methods: longitudinal and radial water blocking.
If ordinary cables are operated in humid environments for extended periods, moisture will gradually penetrate the insulation, eventually damaging the cable's performance and shortening its service life. The FS-YJV uses waterproof materials, allowing it to be used in humid environments where safety and reliability are paramount.

In fact, some rubber-sheathed cables are also waterproof, such as JHS waterproof cables. JHS waterproof cables are suitable for use in equipment requiring water treatment, such as submersible pumps and underwater landscape lights. FS-YJV cables are suitable for use in humid environments such as bathrooms.

Waterproof Cable Waterproofing Methods:
Generally, there are two types of waterproofing: longitudinal waterproofing and radial waterproofing. Commonly used longitudinal waterproofing methods include waterproofing powder, waterproofing yarn, and waterproofing tape. These materials contain a water-swelling substance. When water enters through the cable cross-section or through gaps in the sheath, this substance rapidly expands, preventing further diffusion along the cable's longitudinal direction, thus achieving longitudinal waterproofing. Radial waterproofing is primarily achieved through a protective layer of special materials. FS-YJV is waterproof in the radial direction, but not in the longitudinal direction.
In addition, many customers refer to FS-YJV as rat-proof cable. Whether waterproof or rat-proof cable is determined based on specific needs depends on the specific situation.
