Fluoroplastic or elastic body insulation chlorinated polyethylene jacket feeding and signal cable

Abstract

The invention discloses fluoroplastic or elastic body insulation chlorinated polyethylene jacket feeding and signal cable, and the cable is composed of a cable core, a communication core and an electroline cores. The communication core forms an insulated core through guide and external package of an insulated material, the insulated core is twisted to package a polyester film, and a metal shielding layer is arranged outside the polyester film, a non-woven fabric is packaged outside the metal shielding layer so as to serve as a protective layer; 6 lectroline cores are concentrically twisted on the periphery of the communication core, a PP (parcel post) laniating strap is filled in a gap, and two layer of polyester films are packaged on the periphery of the twisted cable core; and the metal shielding layer is knitted outside the polyester film, a low-smoke no-halogen antiflaming strap is packaged outside the metal shielding layer, and a CPE ( chlorinated poly ethylene) material of an outer package of the antiflaming strap is utilized as an outer sheath. The cable provided by the invention has the advantages that the cable is suitable for being used in a field moving condition, the operating temperature range is minus 40-90 DEG C, the wearability is good, the circumnutating resisting property is strong, ultraviolet radiation is resisted, the core and skin can not be broken after being repeatedly circumnutated, and a drag chain cable used for an abrasion-resistant and circumnutating-resisting port machinery has long service life.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to the technical field of power feeding and signal cables, in particular to a fluorine plastic or elastomer insulated chlorinated polyethylene sheathed power feeding and signal cable. Background technique [0002] In recent years, with the increasing activities of mineral resources mining, exploration, and national defense construction, the demand for special field vehicles, including tanks, self-propelled artillery, and point-vibration surveying and mapping vehicles, has continued to increase. my country has a vast territory and includes All climate zones from the tropics to the frigid zone, so the range of climatic conditions that special vehicles can adapt to is relatively high, and the performance requirements for their auxiliary equipment such as special cables will also become higher and higher. Currently, these special vehicles have Most of the cables are ordinary cabl...

[0002] In recent years, with the increasing activities of mineral resources mining, exploration, and national defense construction, the demand for special field vehicles, including tanks, self-propelled artillery, and point-vibration surveying and mapping vehicles, has continued to increase. my country has a vast territory and includes All climate zones from the tropics to the frigid zone, so the range of climatic conditions that special vehicles can adapt to is relatively high, and the performance requirements for their auxiliary equipment such as special cables will also become higher and higher. Currently, these special vehicles have Most of the cables are ordinary cables, which are not resistant to wear and bending, and cannot be used for a long time in high and low temperature environments, and are far from being able to meet the needs of special vehicles.
