1. Protect wires and cables: Rubber sheaths can provide strong protection for wires and cables, reduce problems such as wear and cuts of wires and cables during use, and extend the service life of wires and cables;

2. Waterproof and moisture-proof: Since the rubber sheath has good waterproof and moisture-proof effects, when used in a humid environment, it can prevent moisture from entering the interior of the wire and cable, and avoid line damage and short circuits caused by moisture.

3. Insulation: The rubber sheath has good insulation properties and can effectively prevent the loss of current and ensure the safe use of wires and cables.

4. Friction resistance: As a friction-resistant material, rubber sheath can effectively reduce friction damage to wires and cables.

Second,purpose of rubber sheath.

In addition to its application in line protection such as wires and cables, rubber sheaths are also widely used in other aspects. for example:

1. Furniture manufacturing: Rubber sheathing can increase the stability of furniture, reduce noise, and improve the comfort of furniture.

2. Automobile manufacturing: Rubber sheaths can reduce car noise and improve car comfort.

3. Manufacturing of water pipe fittings: Rubber sheaths can improve the sealing of water pipe fittings and reduce the problem of water pipe leakage.

4. Industrial production: Rubber sheaths can be used to manufacture industrial products such as valves and pipes to provide protection and reduce production costs.

To sum up, rubber sheath has multiple functions such as protecting wires and cables, being waterproof and moisture-proof, and insulating. It is also widely used in furniture manufacturing, automobile manufacturing, water pipe fittings manufacturing, industrial production and other fields. It is a material of great significance.
