Problems solved by technology

However, the structural design of cables is relatively simple. With the development of the times, higher requirements such as environmental protection have also put forward specific requirements for the environmental protection characteristics and multi-functional integration of elevator cables.
[0005] Traditional elevator cables have always been a difficult problem to resist twisting in the actual working environment

Abstract

The invention discloses a tensile resistance flat electric cable, which comprises conductors, insulation wire cores and a sheath, wherein a flame retarding crosslinked polyolefin insulation layer is lapped on each conductor; a copper wire armoured layer is weaved outside each insulation layer; a flame retarding crosslinked polyolefin insulation layer II is lapped on each copper wire armoured layer to form an insulated wire core; three insulated wire cores are combined to form a cable core; steel wire ropes are arranged among the cable cores; a copper wire armoured layer II is weaved outside the cable cores; a high flame retarding corrosion resistance flexible neoprene sheath layer is lapped on the copper wire armoured layer II. According to the tensile resistance flat electric cable, performance indicators of low smoke, flame retardance shock prevention and the like are met. The tensile resistance flat electric cable also has the advantages of distortion resistance and tensile resistance.

Description

technical field [0001] The invention relates to a tension-resistant flat cable, which belongs to the field of electric wires and cables. [0002] Background technique [0003] Electric cable (electric cable; power cable) is usually a rope-like cable made of several or several groups of wires twisted with at least two wires in each group. Each group of wires is insulated from each other and often twisted around a center. The entire exterior is covered with a highly insulating covering. Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, aluminum alloy cables and so on. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0004] my country's elevator cables began to be developed and developed as early as the 1990s. Under the upsurge of real estate...
