Abstract

The invention discloses a computer shield insulation cable comprising main wire cores, a semiconductive shield layer, a low-smog halogen-free polyolefin sheath, an aluminum belt shield layer and a EPR insulation layer; 12 main wire cores are extruded in the semiconductive shield wrapped by the low-smog halogen-free polyolefin sheath; the low-smog halogen-free polyolefin sheath is wrapped by the aluminum belt shield layer; the aluminum belt shield layer is wrapped by the EPR insulation layer. The cable is good in conductivity, strong in anti-magnetic disturbance performance, mainly applied to the computer and machine room field, long in service life, can go through cycle bending for 1millon times, and is good in high-low temperature resistance, oil resistant, machinery damage resistant, and excellent in chemistry resistant performance.

Description

A kind of computer shield insulated cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of computer shield insulated cable.

Background technology

At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, the cable such as used in the field such as computer, machine room, to the high and low temperature resistance of cable, oil resistant, mechanical resistant damage, can require high all especially in waterproof, water pressure resistance, humidity and chemical resistance aspect.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of long service life, mechanical resistant damage, energy waterproof, watertight computer shield insulated cable.

The present invention takes following technical scheme to realize: a kind of computer shield insulated cable, it is made up of master core, semiconductive shielding layer, low-smoke halogen-free polyolefin restrictive coating, aluminium strip screen and ethylene propylene rubber insulated layer, described master core is 12 groups, be extruded in described semiconductive shielding layer, outer wrapping one deck low-smoke halogen-free polyolefin restrictive coating of described semiconductive shielding layer, outer wrapping one deck aluminium strip screen of described low-smoke halogen-free polyolefin restrictive coating, the ethylene propylene rubber insulated layer of outer wrapping one deck of described aluminium strip screen.

Described master core is made up of aluminium alloy conductor, copper strips armour and copper strip shielding layer.

Described semiconductive shielding layer inner homogeneous is extruded with three nickel wire drainage threads.

The present invention has following beneficial effect in sum: this kind of cable conduction performance is good, diamagnetic interference is strong, be mainly used in the field such as computer, machine room, long service life, reversed bending can be experienced and reach 1,000,000 times, also there is the feature that high and low temperature resistance is good, oil resistant, mechanical resistant are damaged and chemical-resistance is excellent simultaneously.

Accompanying drawing explanation

Fig. 1 is cross-sectional structure schematic diagram of the present invention;

Wherein: 1, master core; 2, semiconductive shielding layer; 3, low-smoke halogen-free polyolefin restrictive coating; 4, aluminium strip screen; 5, ethylene propylene rubber insulated layer; 6, nickel wire drainage thread.

Embodiment

As shown in Figure 1, a kind of computer shield insulated cable, it is made up of master core 1, semiconductive shielding layer 2, low-smoke halogen-free polyolefin restrictive coating 3, aluminium strip screen 4 and ethylene propylene rubber insulated layer 5, described master core 1 is 12 groups, be extruded in described semiconductive shielding layer 2, outer wrapping one deck low-smoke halogen-free polyolefin restrictive coating 3 of described semiconductive shielding layer 2, outer wrapping one deck aluminium strip screen 4 of described low-smoke halogen-free polyolefin restrictive coating 3, the ethylene propylene rubber insulated layer 5 of outer wrapping one deck of described aluminium strip screen 4.

Embodiment: master core 1 is made up of aluminium alloy conductor, copper strips armour and copper strip shielding layer.

Semiconductive shielding layer 2 inner homogeneous is extruded with three nickel wire drainage threads 6.

This cable allows operational environment maximum temperature to be 90 DEG C; The permission bending radius of this cable is 10 times of the outside diameter of cable.

The above is embodiments of the invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
