Problems solved by technology

The application environment of cables is becoming more and more complex, and higher requirements are put forward for cables. Cables not only need to ensure power supply, but also put forward new requirements for safety and reliability; traditional cables have poor high and low temperature resistance, and cannot To meet the installation requirements of high and low temperature resistant ships, general cables have poor flame retardancy and cannot withstand large destructive forces, cannot provide explosion-proof protection for cables, and have poor safety. Traditional cables have high work efficiency during production. The thickness of the layers is uneven, the edges are not neat, and the quality is poor

Abstract

The invention discloses an explosion-proof power cable for ships with high and low temperature resistance. High and low temperature resistant sheath layer, the wire includes a wire core and an insulating layer extruded outside the wire core, and the explosion-proof layer includes a flame-retardant layer and two tinned copper wires respectively located on the inner and outer peripheral surfaces of the flame-retardant layer braided layer; two tinned copper wire braided layers can ensure that the explosion-proof layer can withstand greater destructive force, provide explosion-proof protection for the cable, and the tinned copper wire braided layer can improve the shielding performance and antistatic performance of the cable; the present invention By setting the high and low temperature resistant sheath layer outside the explosion-proof layer, the high and low temperature resistance performance of the cable is greatly improved, and the installation requirements of the cable on high and low temperature resistant ships are met. The explosion-proof layer processing device of the present invention can be quickly produced to obtain explosion-proof Layer, high work efficiency, uniform thickness of explosion-proof layer, neat edges, good quality.

Description

technical field [0001] The invention relates to a cable, in particular to an explosion-proof power cable for ships with high and low temperature resistance. Background technique [0002] With the further deepening of my country's modernization, more and more fields are gradually replaced by electrical equipment, which puts forward higher and higher requirements for the construction of power transmission network. The power transmission network is as large as the high-voltage transmission of thousands of volts of the national grid, and as small as the power supply network of various machinery in the factory, all need cables to realize power transmission. The application environment of cables is becoming more and more complex, and higher requirements are put forward for cables. Cables not only need to ensure power supply, but also put forward new requirements for safety and reliability; traditional cables have poor high and low temperature resistance, and cannot To meet the in...
