UL3535 6-20AWG high temperature electrical cable & wires

JSHFP-30 multi-core shielded watertight cable High voltage1000V

Watertight control cable is mainly used for electrical connection between equipment and is required to work in underwater environment. According to the signal transmission requirements, the signal control line can be composed of multi-strand twisted single-core, multi-core, and multi-pair core wires of different combinations; according to the isolation requirements, the shielding form can be a single-layer shield, a single 2-layer shield, a single-layer total shield, a 2-layer total shield, etc.; according to the use requirements, it can be a longitudinal watertight form or a transverse sealing form.

Longitudinal watertight cable: used for ship piercing connection, high reliability use environment. The cable end face (axial) is required to be able to withstand water pressure, and no water is allowed to seep out within the specified test pressure and time.

Transverse watertight cable: underwater use environment for non-piercing. The cable outer sheath (radial) is required to be able to withstand water pressure, and the cable insulation resistance does not decrease and the cable does not deform within the specified test pressure and time.

Watertight control cables are mainly used for electrical connections between equipment and are required to work in underwater environments. According to signal transmission requirements, signal control cables can be composed of single-core, multi-core, or multi-pair cores of different combinations of stranded strands; according to isolation requirements, the shielding form can be single-layer shielding, double-layer shielding, single-layer overall shielding, double-layer overall shielding, etc.; according to use requirements, it can be longitudinal watertight or transverse sealed.

Longitudinal watertight cable: used for ship docking connection, high reliability use environment. The cable end face (axial) is required to withstand water pressure, and no water is allowed to seep out within the specified test pressure and time.

Transverse watertight cable: underwater use environment for non-dock docking. The cable outer sheath (radial) is required to withstand water pressure, and the cable insulation resistance does not decrease or the cable is not deformed within the specified test pressure and time.
