Abstract

The invention discloses a low smoke halogen-free cable composed of main wire cores, control wire cores, a copper strip tape layer, a low smoke halogen-free polyolefin protective sleeve layer, an armored layer and copper drainage wires. The number of the control wire cores is three, and the number of the main wire cores is three. The control wire cores and the main wire cores are respectively and evenly wrapped inside the copper strip tape layer in a triangle mode. The copper strip tape layer is sequentially wrapped with the low smoke halogen-free polyolefin protective sleeve layer and the armored layer, and the armored layer is formed by weaving annealed copper wires, wherein the surfaces of the annealed copper wires are galvanized. The low smoke halogen-free cable is good in electric conduction performance, low in smoke, free of halogen, high in magnetic disturbance resistance and long in service life and mainly applied to the fields of a computer, a machine room and others, can be bent one million times in a circulation mode and meanwhile has the advantages of being good in high temperature and low temperature resistance and resistant to mechanical damage.

Description

A kind of low-smoke halogen-free cable

Technical field

The invention belongs to field of cables, relate in particular to a kind of low-smoke halogen-free cable.

Background technology

At present, along with Chinese society expanding economy, cable consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the field such as computer, machine room, the aspects such as high and low temperature resistance to cable, oil resistant, resistance to mechanical damage, interference free performance require all high especially.Only meet the requirements, could the better production and application that ensures cable.

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, conduct electricity very well, low smoke and zero halogen, the low-smoke halogen-free cable that diamagnetic interference is strong.

The present invention takes following technical scheme to realize: a kind of low-smoke halogen-free cable, it is made up of master core, control core, copper strips belting layer, low-smoke halogen-free polyolefin restrictive coating, armour and copper wire drainage thread, described control core, described master core are respectively three groups, evenly be extruded in copper strips belting layer inside with triangle respectively, outside described copper strips belting layer, wrap up successively one deck low-smoke halogen-free polyolefin restrictive coating and armour, the annealing proof copper-wire braided that described armour is plating zinc on surface forms.

Described copper strips belting layer inside is also enclosed with three copper wire drainage threads.

The present invention has following beneficial effect in sum: this kind of cable conduction performance is good, low smoke and zero halogen, good flame resistance, diamagnetic interference is strong, be mainly used in the field such as computer, machine room, long service life, can experience reversed bending and reach 1,000,000 times, also there is good, the resistance to mechanical damage of high and low temperature resistance and the good feature of chemical-resistance simultaneously.

Brief description of the drawings

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

Wherein: 1, master core; 2, control core; 3, copper wire drainage thread; 4, copper strips belting layer; 5, low-smoke halogen-free polyolefin restrictive coating; 6, armour.

Embodiment

As shown in Figure 1, a kind of low-smoke halogen-free cable, it is made up of master core 1, control core 2, copper strips belting layer 4, low-smoke halogen-free polyolefin restrictive coating 5, armour 6 and copper wire drainage thread 3, described master core 1, described control core 2 are respectively three groups, evenly be extruded in copper strips belting layer 4 inside with triangle respectively, outside described copper strips belting layer 4, wrap up successively one deck low-smoke halogen-free polyolefin restrictive coating 5 and armour 6, the annealing proof copper-wire braided that described armour 6 is plating zinc on surface forms.

Described copper strips belting layer 4 inside are also enclosed with three copper wire drainage threads 3.

It is 100 DEG C that this cable allows operational environment maximum temperature; The permission bending radius of this cable is the outside diameter of cable 10 times.

The above is embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
