At the same time, it has the characteristics of high transmission rate, small line loss; high safety performance, no environmental pollution; low installation and maintenance costs.

Description

New wear-resistant and pressure-resistant control cables

technical field

The utility model relates to a cable, in particular to a novel wear-resistant and pressure-resistant control cable.

Background technique

With the rapid development of my country's industry, ordinary control cables cannot meet certain places with large power consumption and high withstand voltage requirements, such as subways, nuclear power plants, shopping malls, hospitals, intelligent buildings and other electrical equipment with high safety and reliability requirements place. Therefore, the scope and amount of plastic insulated control cables in industry continue to increase.

Utility model content

In order to solve the above problems, the utility model provides a novel wear-resistant and pressure-resistant control cable with simple structure, low production cost and long service life.

The technical scheme of the utility model is: the cable includes three insulated wire cores, each of the insulated wire cores includes a conductor, an insulating layer and a shielding layer arranged from the inside to the outside, and the three insulated wire cores are extruded together Wrapping the tape to form a cable core, the cable core is provided with a metal armor layer, and the metal armor layer is provided with an outer sheath.

The insulating layer is a fluoroplastic insulating layer.

The shielding layer is a copper-clad aluminum wire braided shielding layer.

The metal armor layer is a steel tape armor layer.

The outer sheath is a silicone rubber sheath.

The utility model has the advantages of simple structure, wear resistance and pressure resistance, low production cost and long service life, and improves the wear resistance and pressure resistance of the cable. This type of cable overcomes the blank of traditional control cables and has excellent pressure resistance and high shielding. At the same time, it has the characteristics of high transmission rate, small line loss; high safety performance, no environmental pollution; low installation and maintenance costs.
