Abstract

The invention discloses a metallurgical high-temperature-resistant power cable which mainly comprises main wire cores, ground wire cores, control wire cores, a semi-conductive packing layer, a wrapping layer, an insulation shielding layer and a galvanized copper wire braided armor jacket layer. The two sets of main wire cores, the two sets of ground wire cores and the four sets of control wire cores are arranged in the semi-conductive packing layer in an extruding mode. The semi-conductive packing layer is coated with the wrapping layer. The wrapping layer is coated with the insulation shielding layer. The insulation shielding layer is coated with the galvanized copper wire braided armor jacket layer. The metallurgical high-temperature-resistant power cable has the advantages of being widely suitable for the fields of metallurgy, electric power, the chemical industry, tunnels and the like, good in shielding performance and high in high temperature resistance and corrosion resistance.

Description

A kind of metallurgy high-temperature-resistant power cable

Technical field

The invention belongs to field of cables, relate in particular to a kind of metallurgy high-temperature-resistant power cable.

Background technology

At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the fields such as metallurgy, electric power, chemical industry, tunnel, in the useful life to cable, shielding properties, requirement high temperature resistant, corrosion resistance aspect are all high especially, only meet the requirements, could improve in these fields the fail safe while manufacturing.

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 high temperature resistant, metallurgy high-temperature-resistant power cable that corrosion resistance is strong.

The present invention takes following technical scheme to realize: a kind of metallurgy high-temperature-resistant power cable, it be mainly by master core, core, control core, semiconductive packed layer, belting layer, insulation screen and zinc-plated brass wires braided armored restrictive coating, in described semiconductive packed layer, be extruded with two groups of master cores, two groups of ground cores and four groups of control cores, described semiconductive packed layer outer wrapping one deck belting layer, described belting layer outer wrapping one deck insulation screen, the zinc-plated brass wires braided armored restrictive coating of one deck of described insulation screen outer wrapping.

Described master core by tinned copper conductor and the aluminium strip armour, teflon insulation layer and the low-smoke halogen-free polyolefin sheath that are wrapped in successively outside tinned copper conductor form.

Described ground core by copper conductor and the copper strips armour being wrapped in successively outside copper conductor form.

Described control core is comprised of nickel conductor and the aluminium strip armour that is wrapped in successively outside nickel conductor.

The present invention has following beneficial effect in sum: this cable is widely used in the fields such as metallurgy, electric power, chemical industry, tunnel, has advantages of advantages of good shielding performance, high temperature resistant, corrosion resistance is strong;

Master core conductor is tinned copper conductor, can effectively prevent conductor oxidized increase resistance in using the course of work, causes high temperature and the fire that may cause occurs;

The external sheath layer of this cable adopts nonmagnetic metal armouring as restrictive coating, has strengthened the tensile property of cable, and what cable internal core was protected is more abundant, the fail safe that has improved cable.

Wherein: 1, master core; 2, core; 3, control core; 4, semiconductive packed layer; 5, belting layer; 6, insulation screen; 7, zinc-plated brass wires braided armored restrictive coating.

Embodiment

As shown in Figure 1, a kind of metallurgy high-temperature-resistant power cable, it be mainly by master core 1, core 2, control core 3, semiconductive packed layer 4, belting layer 5, insulation screen 6 and zinc-plated brass wires braided armored restrictive coating 7, in described semiconductive packed layer 4, be extruded with two groups of master cores 1, two groups of ground cores 2 and four groups and control cores 3, described semiconductive packed layer 4 outer wrapping one deck belting layers 5, described belting layer 5 outer wrapping one deck insulation screens 6, the zinc-plated brass wires braided armored restrictive coating 7 of one deck of described insulation screen 6 outer wrapping.

Embodiment: described master core 1 by tinned copper conductor and the aluminium strip armour, teflon insulation layer and the low-smoke halogen-free polyolefin sheath that are wrapped in successively outside tinned copper conductor form.

Described ground core 2 by copper conductor and the copper strips armour being wrapped in successively outside copper conductor form.

Described control core 3 is comprised of nickel conductor and the aluminium strip armour that is wrapped in successively outside nickel conductor.

This cable allows bending radius to be not less than 12 times of the outside diameter of cable, its shielding transfer impedance in 100MHz scope with the interior 1 Ω/m that is not less than.

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.
