Description

Fluoroplastic insulated high temperature resistant power cable

technical field

The utility model mainly relates to the field of cables, in particular to a fluoroplastic insulated high temperature resistant power cable.

Background technique

At present, with the development of society, the power consumption on the ship is also increasing, the current carrying capacity of the cable is required to be larger and larger, the interface of the cable conductor of the cable is constantly increasing, and the weight of the cable per unit length increases accordingly. . When the staff is laying cables, it is easy to scratch the outer sheath during the laying process, thereby leaving hidden dangers to safety and causing accidents. In the prior art, most of the insulating layer and the sheath of the cable are organic mixtures of plastic and rubber, and they generally have poor wear resistance.

In the event of a fire, the flame will spread with the cable, and at the same time, a large amount of smoke and toxic corrosive gas will be produced, which will be harmful to the human body. In order to reduce the speed of spreading along the cable when the flame burns, various flame retardant additives are usually added to the cable material to make various types of flame retardant materials and flame retardant cables. Therefore, flame retardancy, corrosion, smoke, and toxicity are generally used to evaluate the performance of power cables when they burn.

Utility model content
