Problems solved by technology
In order to protect the safety of people's lives and property, people's requirements for power cables are getting higher and higher. It is difficult to guarantee the elasticity and compressive performance of traditional power cables, and the safety and stability of cables are poor, so it is difficult to meet the needs of use.
After the cable is laid and installed, it is more susceptible to external extrusion and stretching, especially in the process of anti-extrusion, the wires in the cable core are easy to deform or even break the core, which cannot guarantee the smooth transmission of power and communication, resulting in huge economic losses.

The invention provides an extrusion-resistant copper cable. The cable comprises a wire core, each wire core is composed of a copper wire and an insulating layer. The copper wire is wrapped in the insulating layer, a filling layer is arranged outside the wire core, an inner protective layer is arranged outside the filling layer, the inner protective layer is a metal sheath, buffer extrusion balls are arranged between the filling layer and the inner protective layer, a wear-resistant outer protective layer is arranged outside the inner protective layer, and the wear-resistant outer protective layer is a high-strength nylon sheath. The cable has the advantages of good extrusion resistance, good tensile resistance and good structural stability.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to an extrusion-resistant copper cable. Background technique [0002] With the rapid development of my country's social economy, there are more and more crowded places such as subways, airports, railways, tunnels and other important engineering facilities, intelligent communities, large supermarkets, and public places. In order to protect the safety of people's lives and property, people's requirements for power cables are getting higher and higher. It is difficult to guarantee the elasticity and compressive performance of traditional power cables, and the safety and stability of cables are poor, making it difficult to meet the needs of use. After the cable is laid and installed, it is more susceptible to external extrusion and stretching, especially in the process of anti-extrusion, the wires in the cable core are easily deformed or even broken, which cannot guarantee the smooth tra...
