Description

A kind of improved weak-current cable

Technical field

It the utility model is related to a kind of cable, and in particular to a kind of weak-current cable.

Background technology

Light current be with electric power, electric consumption on lighting in contrast, generally transmitting signal, carry out information exchange electric energy call Light current.The process object of light current is mainly information, i.e. the transmission and control of information, its main feature is that voltage is low, electric current is small, power It is small, frequency is high.

Existing weak-current cable generally use multi-core conductor, this multi-core conductor generally existing consumptive material is more, winding poor performance The problems such as, also, application environment is frequently present of the phenomenon that a plurality of different electric wires work at the same time in actual life, has at the same time Many electrical equipments are being run, these electrical equipments and electric wire inevitably cause to radiate during the work time, This radiation can cause the signal transmission of weak-current cable to be affected.

The content of the invention

Goal of the invention：The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of structure setting Rationally, tensile strength is high, and winding performance is good, can avoid the improved weak-current cable of magnetic field and radio signal interference.

Technical solution：In order to solve the above-mentioned technical problem, a kind of improved weak-current cable described in the utility model, it is wrapped Conductor is included, internal shield is equipped with outside the conductor, inner insulating layer is equipped with outside the internal shield, in the interior insulation Layer is exterior to be equipped with external shielding layer, and external insulation layer, the internal shield, inner insulating layer, external screen are equipped with outside the external shielding layer Cover layer and four layers of external insulation layer is co-extruded, interior braiding layer is equipped with outside the external insulation layer, they form conductive unit, institute Conductive unit is stated at least provided with two, filled layer is equipped with outside the conductive unit, is equipped with outside the filled layer wrapped Layer, Ceramic silicon rubber layer is equipped with outside the lapping layer, outer braiding layer is equipped with outside the Ceramic silicon rubber layer, Flame-retardant layer is equipped with outside the outer braiding layer, oversheath is equipped with outside the flame-retardant layer.

The conductor is anaerobic copper conductor.

The interior braiding layer by aramid fiber silk according to 1 repeatedly 2 vertical wovens form.

The outer braiding layer by spandex fibre silk according to 2 repeatedly 1 vertical woven form.

The flame-retardant layer is high fire-retardance polyethylene layer.

Beneficial effect：Compared with prior art, its remarkable advantage is the utility model：The utility model overall structure is set Rationally, Integral sealing, more more stable than fine copper, fine aluminium cable using anaerobic copper conductor, electrical conductivity higher, using by aramid fiber Silk according to the 1 repeatedly interior braiding layer that forms of 2 vertical wovens, and using by spandex fibre silk according to 2 repeatedly 1 vertical woven form it is outer Braiding layer, effectively improves the tensile strength of core unit, and using internal shield and external shielding layer, antijamming capability is stronger, uses Four layers of coextruded layer being made of internal shield, inner insulating layer, external shielding layer and external insulation layer, winding performance is good, using ceramic Silastic-layer and flame-retardant layer, can effectively improve overall fire protecting performance, and this product is coordinated by each layer, operate steadily reliable, whole Body service life is grown, and meets actual operation requirements.
