Water-resistant rat-proof anti-termite cold-resistant soft power cable

Abstract

The invention discloses a water-resistant rat-proof anti-termite cold-resistant soft power cable and relates to the technical field of cables. The soft power cable comprises a 5-class soft structure copper conductor and a halogen-free low-smoke inflaming-retarding polyolefin sheath layer. The 5-class soft structure copper conductor is wrapped by crosslinked polyethylene insulation layer to form wire cores, and the four wire cores are wrapped by a halogen-free low-smoke inflaming-retarding belt to form a cable core. A halogen-free low-smoke inflaming-retarding fillign rope is arranged in the cable core, a water-resistant belt is arranged on the outside of the cable core in a winding mode, and the rat-proof anti-termite cold-resistant halogen-free low-smoke inflaming-retarding polyolefin sheath layer wraps the water-resistant belt. The 5-class soft structure copper conductor is adopted, flexibility of the cable structure is ensured, the cable is easy to bend, adopted non-metal materials are all halogen-free inflaming-retarding materials, no halogen is released under fire, no secondary harm is caused, and the cable is good in the whole inflaming retarding performance and capable of achieving A-class beaming group burning effects. The cable sheath adopts the halogen-free low-smoke inflaming-retarding polyolefin material, so that the cable is water-resistant, rat-proof, anti-termite, cold-resistant, environmentally friendly, and suitable to be used in the district with the environment temperature of -40 DEG C.

Description

technical field

[0001] The invention relates to cables, in particular to a water-blocking, rodent-proof, termite-proof, and cold-resistant flexible power cable. Background technique

[0002] With the development of the economy, all walks of life have different requirements for the performance of cables. Especially for cables used in public facilities, it is required to have special requirements such as water resistance, anti-rat gnawing, anti-termite corrosion, environmental protection and no secondary hazards.

[0003] The climatic conditions are different in different regions. Some regions have low temperature all year round, and some places have a large temperature difference between day and night. For example, in Inner Mongolia and Northeast China, the ambient temperature in winter reaches minus 30 degrees. Ordinary PVC cables can be used when the ambient temperature is relatively low. The insulation and sheath are hardened, even brittle and cracked, which brings safety...
