A double flame-retardant power cable for fire protection

Abstract

The invention discloses a special double-flame-retardant power cable for fire protection, which comprises high-temperature-resistant rubber, and is characterized in that metal cables are fixedly connected in the high-temperature-resistant rubber, the outer surface of each metal cable is fixedly connected with an inner rubber layer, the outer surface of each inner rubber layer is fixedly connectedwith an outer rubber layer, the internal part of the high-temperature-resistant rubber is fixedly connected with a cable thin wire at the side close to each metal cable, and the outer surface of eachcable thin wire is wound with a copper wire. The special double-flame-retardant power cable for fire protection not only plays a role of resisting the high temperature but also carry out further fireprotection on the special double-flame-retardant power cable for fire protection in the using process through arranging the high-temperature-resistant rubber. The cooperative arrangement of the innerrubber layer and the outer rubber layer enables the special double-flame-retardant power cable for fire protection to have protection measures to prevent electric leakage and short circuit in the using process.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a double flame-retardant power cable for fire protection. Background technique [0002] Wire and cable refers to materials used for power, communication and related transmission purposes. There is no strict boundary between "wire" and "cable". Usually, products with few cores, small product diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables; Small ones (less than or equal to 6 square millimeters) are called small wires, and insulated wires are also called cloth wires. Today's high-resolution video displays require high-performance cables with low signal delay and low return loss. Typically, these systems use bundled coax for cable interconnection, but due to the economics of unshielded twisted pair (UTP) over coax, system designers have turned to UTP transmission equipment for RGB component video t...
