The invention discloses a polyethylene insulated fire-resistant computer cable, which relates to the technical field of cables. The double-layer synthetic mica refractory layer is sleeved on the outer surface of the tinned annealed copper conductor, the silicone rubber insulation is sleeved on the outer surface of the double-layer synthetic mica refractory layer, and the woven glass fiber yarn is sleeved on the outer surface of the silicone rubber insulation. Tin-soft copper conductor, double-layer synthetic mica refractory layer, silicone rubber insulation and braided glass fiber yarn are set in two inside the metal / fiber composite braided sub-shield, which solves its poor fire resistance, high temperature resistance and anti-interference , the accuracy and stability of signal transmission are poor, and the anti-pull ability and bending flexibility are poor, which affects the use requirements, making it have good fire resistance, high temperature resistance, and anti-interference performance. It can ensure the accuracy of signal transmission. It also has high tensile and dragging ability and bending flexibility. It can meet the requirements of various cable laying and installation, bearing capacity, fire performance and signal transmission.
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...
