Description

A high temperature resistant cable

technical field

The utility model relates to the technical field of cables, in particular to a high temperature resistant cable.

Background technique

A cable refers to a rope-like cable that is usually twisted by several or several groups of wires. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating coating. The cable has the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc.

Commonly used cables generally use a protective layer made of polyvinyl chloride to protect the cable core inside the cable. The protective layer made of polyvinyl chloride is flame retardant and insulating, and is a good cable protective layer material , but the disadvantages of polyvinyl chloride are also obvious. It cannot withstand high temperature. In some high-temperature production environments, if the cable made of polyvinyl chloride protective layer is used, the outer shell of the cable will age faster, which will eventually lead to cable damage and cause Security risks.
