How to choose rubber sheathed cables correctly

Rubber sheathed cable is a flexible and movable cable made of multiple thin copper wires as conductors, wrapped with rubber insulation and rubber sheath. This type of cable has a wide range of applications in multiple fields, especially in mining environments, and its importance is self-evident. Below, I will provide a detailed introduction to rubber sheathed cables from several aspects:

1、 Main types and characteristics

Rubber sheathed cables can be classified into various types based on their usage and performance, including but not limited to:

1. ‌General rubber sheathed flexible cableThis type of cable is usually used as a mobile power cord for daily electrical appliances, electric machinery, and other equipment, with good flexibility and bending performance.

2. ‌Welding machine cableSpecially designed for welding machines, capable of withstanding high currents and mechanical stresses, suitable for secondary side wiring and connecting welding tongs for welding machines with ground voltage AC not exceeding 200V and pulsating DC peak 400V.

3. ‌Submarine motor cableMainly used for matching submersible motors, it has excellent waterproof performance and can work for a long time in underwater environments without damage.

4. ‌Waterproof rubber sheathed cableJHS type cables, designed specifically for underwater equipment such as submersible pumps, can maintain good electrical insulation performance under long-term immersion and high water pressure.

2、 Structure and Performance

The structure of rubber sheathed cables generally consists of conductors, insulation layers, sheaths, and other parts. Among them, the conductor adopts multiple strands of thin copper wire to ensure smooth transmission of current; The insulation layer is made of rubber mixture and other materials, which have good insulation performance; The sheath is made of rubber material to protect and enhance the flexibility of the cable.

This type of cable has stable and reliable performance, and can adapt to various harsh working environments such as high temperature, humidity, corrosion, etc. At the same time, according to the mechanical external force acting on the cable, rubber sheathed cables can be divided into three categories in terms of product structure: light, medium, and heavy, to meet the needs of different occasions.
