Polyethylene insulation fireproof computer cable

Abstract

The invention discloses a polyethylene insulation fireproof computer cable, and relates to the technical field of cables. The polyethylene insulation fireproof computer cable is characterized in that:a tinned soft copper conductor is sleeved with a double-layer synthetic mica fireproof layer, the double-layer synthetic mica fireproof layer is sleeved with a silicone rubber insulation sleeve, andthe silicone rubber insulation sleeve is sleeved with braided glass fiber yarns. The two integral parts composed of the tin-plated soft copper conductors, the double-layer synthetic mica fireproof layers, the silicone rubber insulation layers and the braided glass fiber yarns are arranged in a metal / fiber composite braided sub-shield, so that the problems of poor fire resistance, poor high temperature resistance, poor interference resistance, poor accuracy and poor stability of signal transmission, poor pulling resistance, poor bending flexibility and influence on use requirements are solved,the polyethylene insulation fireproof computer cable has good fireproof, high-temperature-resistant and anti-interference performances, can guarantee the accuracy and stability of signal transmission,also has higher tensile and dragging resistance and bending flexibility, and can meet the requirements of laying installation, bearing capability, fireproof performance and signal transmission of various cables.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a polyethylene insulated fire-resistant computer cable. Background technique [0002] With the rapid development of social industrialization, people have higher and higher requirements for cable performance. In order to meet the needs of social development, it is particularly important to develop special cables that can meet the needs of special applications in time. It is an instrument signal control system for some special occasions that require high temperature resistance, flexibility, and drag resistance. [0003] Traditional computer cables have certain defects in use, such as poor fire resistance, high temperature resistance, and anti-interference, poor accuracy and stability of signal transmission, and poor drag resistance and bending flexibility, which affect the use requirements. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the presen...
