Abstract

The invention, which belongs to the cable manufacturing field, relates to a shielding cable used in a copper-cladding-aluminum-core low-smoke zero-halogen electronic computer apparatus. The shielding cable is characterized in that: the shielding cable used in the copper-cladding-aluminum-core low-smoke zero-halogen electronic computer apparatus comprises several cable cores; conductive cores in the cable cores are wrapped with insulating layers; the insulating layers are wrapped with shielding layers; the cable cores are wrapped together by using a belting; the belting is wrapped with a total shielding layer; an oversheath is arranged out of the total shielding layer; the conductive cores are copper cladding aluminum cores, the insulating layers are made of crosslinking polyethylene insulating materials and the oversheath is made of low smoke, non-halogen polyolefin flame retardant materials. The cable possesses characteristics of thermostability, flame retardation, good interference immunity to electric and magnetic fields.

Description

The low cigarette of copper-covered aluminum-core does not have low halogen Electronic Accounting Machine Unit shielded type cable

Technical field

The present invention relates to the low cigarette of a kind of copper-covered aluminum-core does not have low halogen Electronic Accounting Machine Unit shielded type cable, belongs to the cables manufacturing field.

Background technology

At present, computer is widely used in each big industry, in some special workplaces, then computer is had higher requirement with cable: high temperature resistant, fire-retardant, have good anti-electric field, magnetic interference performance, under occasions such as low frequency, high frequency, hyperfrequency and frequency conversion, still have accurate interference free performance.Yet traditional material can't satisfy the instructions for use of these particular surroundingss.Simultaneously, the working strength of cable is big in industries such as petrochemical industry, electric power, metallurgy, temperature is high, and operational environment is than security incidents such as the easier breaking out of fire blasts of other occasions.Therefore, require cable must have the characteristic of fire resistance and burning back LSZH.Common computer adopts the flame-proof PVC material as insulation and oversheath with cable, yet PVC can discharge a large amount of halogen acid gas when burning, and the equipment and instrument around the heavy corrosion is harmful to health simultaneously.

Summary of the invention

In view of the defective that prior art exists, the purpose of this invention is to provide the low cigarette of a kind of copper-covered aluminum-core does not have low halogen Electronic Accounting Machine Unit shielded type cable, and this cable has high temperature resistant and fire-retardant characteristic, and has good anti-electric field, magnetic interference performance.

The technical solution adopted for the present invention to solve the technical problems is: the low cigarette of a kind of copper-covered aluminum-core does not have low halogen Electronic Accounting Machine Unit shielded type cable, the low cigarette of described copper-covered aluminum-core does not have low halogen Electronic Accounting Machine Unit and comprises some cable cores with shielded type cable, the outer lapped insulation layer of conductor wire core in the cable core, insulating barrier outer wrapping sub-shield; Utilize band that cable core is bundled together, at the total screen of band outer wrapping, total screen peripheral hardware oversheath; Described conductor wire core is a copper-covered aluminum-core, and described insulating barrier adopts crosslinked polyethylene insulation material, and described oversheath adopts the polyolefin halogen-free low-smoke flame retardant material.

Described copper-covered aluminum-core is that the outer surface at aluminium bar core wraps up copper strips with one heart, forms the composite bed of metallurgical binding between atom between copper strips and the aluminium bar core.

The invention has the beneficial effects as follows: the low cigarette of a kind of copper-covered aluminum-core does not have low halogen Electronic Accounting Machine Unit shielded type cable, the low cigarette of described copper-covered aluminum-core does not have low halogen Electronic Accounting Machine Unit and comprises some cable cores with shielded type cable, the outer lapped insulation layer of conductor wire core in the cable core, insulating barrier outer wrapping sub-shield; Utilize band that cable core is bundled together, at the total screen of band outer wrapping, total screen peripheral hardware oversheath; Described conductor wire core is a copper-covered aluminum-core, and described insulating barrier adopts crosslinked polyethylene insulation material, and described oversheath adopts the polyolefin halogen-free low-smoke flame retardant material.This cable has high temperature resistant and fire-retardant characteristic, and has good anti-electric field, magnetic interference performance.
