CN203721366U - Anti-interference fireproof power cable - Google Patents

Abstract

The utility model discloses an anti-interference fireproof power cable. The cable is composed of a copper covered steel armored layer, a fluorubber oversheath and main wire cores. Each main wire core is formed by wrapping multiple strands of silver-coated copper wire stranded conductors by a polyvinyl chloride insulation layer in an extruded mode; four main wire cores tightly extrude a square inorganic fiber inner core; four shielding wire cores are arranged at the gaps at the outer sides of the contact positions of every two main wire cores; a ceramic silicone rubber wrapping layer wraps the four main wire cores and the four shielding wire cores to form a cable core; the gap in the cable core is filled up with a silicon carbide composite material filler; the copper covered steel armored layer is arranged outside the cable core; and the copper covered steel armored layer is wrapped by the fluorubber oversheath in an extruded mode. The cable provided by the utility model has the advantages of light weight, high structural strength, high temperature resistance, excellent fire resistance and anti-interference performance, and good shielding performance.

Description

A kind of anti-interference fireproof power cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of anti-interference fireproof power cable.

Background technology

Along with the fast development of national economy, as the aortal electric wire of national economy, its consumption and the scope of application are increasing.In recent years, the industries such as power plant, transformer station, smelting and petrochemical industry, very big to the demand of cable.At present, the cable on market is various, and they are applied in various different occasions.But all there are some problems in most of cable, such as when the breaking out of fire, the easy heat damage of cable, thus affect the overall operation of cable, and a little less than signal shielding performance, anti-interference is poor, can not long-time continual steady operation etc.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of anti-interference fireproof power cable.

The utility model takes following technical scheme to realize: a kind of anti-interference fireproof power cable, it is comprised of copper covered steel armour, fluorubber oversheath and master core, described master core is by polyvinyl chloride insulation layer, to extrude multiply silver-gilt copper wire stranded conductor to form, and four master cores closely extrude a square inorfil inner core; Four shielding cores are arranged in the outer side clearance of every two master cores contact; Ceramic silicon rubber lapping layer becomes cable core by four master cores and four shielding cores are wrapped; In gap in described cable core, be filled with composite material of silicon carbide filler; Described copper covered steel armour is arranged on outside cable core; Described fluorubber oversheath is extruded on copper covered steel armour.

The utlity model has in sum following beneficial effect: this cable is applicable to spread the power cable into underground, have lightweight, structural strength is high, high temperature resistant, fire-resistant and interference free performance is excellent, advantages of good shielding performance.

Accompanying drawing explanation

Fig. 1 is the utility model cross-sectional structure schematic diagram;

Wherein: 1, silver-gilt copper wire stranded conductor; 2, polyvinyl chloride insulation layer; 3, shielding core; 4, composite material of silicon carbide filler; 5, ceramic silicon rubber lapping layer; 6, copper covered steel armour; 7, fluorubber oversheath; 8, square inorfil inner core.

Embodiment

As shown in Figure 1, a kind of anti-interference fireproof power cable, it is comprised of copper covered steel armour 6, fluorubber oversheath 7 and master core, described master core is by polyvinyl chloride insulation layer 2, to extrude multiply silver-gilt copper wire stranded conductor 1 to form, and four master cores closely extrude a square inorfil inner core 8; Four shielding cores 3 are arranged in the outer side clearance of every two master cores contact; Ceramic silicon rubber lapping layer 5 becomes cable core by four master cores and four shielding cores are wrapped; In gap in described cable core, be filled with composite material of silicon carbide filler 4; Described copper covered steel armour 6 is arranged on outside cable core; Described fluorubber oversheath 7 is extruded on copper covered steel armour 6.

The above is the utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
