Waterproof rubber cable JHS is used to connect submersible motors with AC voltage of 300/500V and below. One end of the cable is in water and the working temperature is not more than 60 °C for a long time. JHS waterproof cable insulation material: waterproof rubber for insulation; waterproof rubber for cable filling; waterproof rubber jacket for cable jacket for submersible pump, coal mine, underwater operation, water glazing and other water treatment equipment, this product The use of high-density glue has the function of waterproofing.
Waterproof rubber cable JHS that can be used normally in water are collectively referred to as water-blocking (waterproof) power cables. When the cable is laid under water, where it is often immersed in water or humid, the cable is required to have the function of preventing water. It requires a full water blocking function to prevent moisture from immersing inside the cable, causing damage to the cable and ensuring the cable. Long-term stable operation under water. The difference between a waterproof cable and a normal cable is that ordinary cables cannot be used in water.
There are two main types of waterproof cables:
1.An oil-paper insulated cable is the most typical water-resistant cable. Its insulation and conductor are filled with cable oil, and the outer sheath has a metal sheath (lead sleeve or aluminum sleeve), which is the best water resistance cable. In the past, oil-paper insulated cables were used for submarine (or underwater) cables, but oil-paper insulated cables were limited by the drop, oil leakage was troublesome, and maintenance was inconvenient, and now it is used less and less.
2. Ethylene-propylene rubber insulated cable widely used in medium and low voltage underwater transmission lines, waterproof rubber cable (JHS type) can be safely operated in shallow water for a long time.
