Abstract
The utility model discloses a fire resistant shielding cable, which comprises a plurality of conductor wire cores provided with high temperature insulation layers, wherein a plurality of conductor wire cores are tied into single conductor units through a first fire resistant belting layer, a plurality of the single conductor units are tied into a whole through a second fire resistant belting layer, the second fire resistant belting layer is wrapped by a weaving shield layer outside, and a sheath layer is arranged outside the wrapped weaving shield layer. The cable provided by the utility model has excellent fire resistant performance and low manufacture cost, and is a fire resistant shielding computer cable with excellent manufacture performance.
Description
Technical field
The utility model relates to high temperature resistant computer shield field of cables, especially concrete a kind of high temperature resistant shielded type cable.
Background technology
Existing high temperature resistant computer cable frequency of utilization scope is 30kHz and following, belongs to low frequency signal control signal cable.High temperature resistant computer cable adopts copper wire braiding or the wrapped shielding form of copper strips, and there is certain defective in this type of shielding construction, can play effective function to electric field shielding under low frequency signal, but bad for the magnetic field shielding effect.Computer cable is laid in the house cable ditch, when user's design, purchased cable, generally do not design steel band or steel wire armour product, substantially there is not the armouring series products to sell on the computer cable market, therefore the present shielding form of computer cable is poor for the resultant effect of electromagnetic shielding, can not satisfy the needs of electromagnetic shielding fully.
The utility model content
The purpose of this utility model provides a kind of high temperature resistant shielded type cable, and resistance to elevated temperatures is good, makes low cost, the dynamo-electric cable of the high temperature resistant SHIELDING CALCULATION that processing characteristics is good.
The technical solution of the utility model is as follows:
A kind of high temperature resistant shielded type cable, include the conductor thread core that several have high-temperature insulating layer, several conductor thread cores are wrapped up into single conductor element by the first high temperature resistant belting layer, several single conductor elements are integral by the second high temperature resistant belting layer wrapping, the second high temperature resistant belting layer is wrapped with woven shield, is enclosed with woven shield and is provided with restrictive coating outward.
Described braid shielded layer material is tinning steel-in-copper silk or tinned copper wire and steel wire.
Described high temperature resistant belting layer is high temperature GRPP band.
Temperature-resistant insulation layer of the present utility model is fluoroplastics or silicon rubber insulation material, high temperature resistant belting layer is the GRPP band, temperature resistant grade reaches 280 degree, satisfy the needs of cable working temperature, the braid material is the tinned copper wire and the steel wire of tinning steel-in-copper silk or the braiding of the different directions divided equally, the type of weave that adopts high conductive material and high permeability material to mix, under the low frequency situation, have electric screen and magnetic screen double effects, can reach the electromagnetism composite shielding, oversheath is fluoroplastics or silastic material.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of high temperature resistant shielded type cable, include several conductor thread cores that has high-temperature insulating layer 21, several conductor thread cores 1 are wrapped up into single conductor element by the first high temperature resistant belting layer 3, several single conductor elements are integral by second high temperature resistant belting layer 4 wrappings, outside the second high temperature resistant belting layer 4 woven shield 5 is arranged, the woven shield 5 outer restrictive coatings 6 that are provided with.Woven shield 5 can be tinning steel-in-copper silk or tinned copper wire and steel wire, and the first high temperature resistant belting layer 3, the second high temperature belting layer 4 are high temperature GRPP band.
