CN103915173A - High-temperature-resistant corrosion-prevention FEP cable - Google Patents

Abstract

The invention discloses a high-temperature-resistant corrosion-prevention FEP cable. The FEP cable is mainly composed of main cable cores, a silicone rubber taping layer, a copper tape armored layer, an FEP insulating layer and a protective sleeve, wherein the outer sides of the main cable cores are wrapped in the silicone rubber taping layer, the copper tape armored layer, the FEP insulating layer and the protective sleeve in sequence, the number of the main cable cores is three, and the main cable cores are evenly wrapped in the silicone rubber taping layer in an extruded mode; a grounded cable core is further wrapped in the silicone rubber taping layer; three current guiding wires are wrapped in the copper tape armored layer, and each current guiding wire is formed by wrapping a plurality of annealed wires in copper wires. The cable has a good insulating property and is capable of retarding inflaming and resisting high temperature, corrosion and ageing and long in service life, thereby being widely applied to the fields of power generation, metallurgy, chemical engineering, petroleum and the like. Meanwhile, the FEP cable further has the advantages of oxidation resistance, interference resistance, dragging resistance and the like.

Description

A kind of perfluoroethylene-propylene fire resistant anticorrosive cable

technical field

The present invention relates to field of cables, relate in particular to a kind of perfluoroethylene-propylene fire resistant anticorrosive cable.

Background technology

At present, along with electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved.

Such as the cable using in the fields such as generating, metallurgy, chemical petroleum, to the fire resistant of cable, acid and alkali-resistance, corrosion-resistant, the requirement of the aspects such as oil resistant is anti-oxidant is all high especially, be generally not admit of potential safety hazard to exist, only meet the requirements, the fail safe could improve in these fields the manufacturing time.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one have fire-retardant, fire resistant, the perfluoroethylene-propylene fire resistant anticorrosive cable of the advantages such as anticorrosion, antioxidation.

The present invention takes following technical scheme to realize: a kind of perfluoroethylene-propylene fire resistant anticorrosive cable; it mainly by master core and the silicon rubber belting layer, copper strips armour, perfluoroethylene-propylene insulating barrier and the protective sleeve that are wrapped in successively master core outside form; described master core is three groups; evenly be extruded in described silicon rubber belting layer inside; a ground connection core is also wrapped up in described silicon rubber belting layer inside; three drainage threads of described copper strips armour internal package, described drainage thread is made up of the outer coppered wire of some strands of annealed wires.

Described master core is made up of copper conductor and the fluorubber insulating barrier, the aluminium foil braid that are wrapped in outside copper conductor, and described fluorubber insulating barrier inside is provided with an aluminium wire heater wire.

Described protective sleeve is to be made up of the butyronitrile material that adds micaceous organic silicon ribbon, anticorrosive and antioxidant.

The present invention has following beneficial effect in sum: this cable has good insulation property, flame-resistant high-temperature-resistant, long service life, be widely used in the fields such as generating, metallurgy, chemical petroleum, corrosion-resistant, ageing-resistant, also there is anti-oxidant, the anti-interference and anti-advantage such as pull simultaneously.

Embodiment

As shown in Figure 1; a kind of perfluoroethylene-propylene fire resistant anticorrosive cable; it is mainly made up of master core 1 and the silicon rubber belting layer 2, copper strips armour 4, perfluoroethylene-propylene insulating barrier 6 and the protective sleeve 7 that are wrapped in successively master core 1 outside; described master core 1 is three groups; evenly be extruded in described silicon rubber belting layer 2 inside; a ground connection core 8 is also wrapped up in described silicon rubber belting layer 2 inside; three drainage threads 3 of described copper strips armour 4 internal package, described drainage thread 3 is made up of the outer coppered wire of some strands of annealed wires.

Described master core 1 is made up of copper conductor and the fluorubber insulating barrier, the aluminium foil braid that are wrapped in outside copper conductor, and described fluorubber insulating barrier inside is provided with an aluminium wire heater wire.

Described protective sleeve 7 is to be made up of the butyronitrile material that adds micaceous organic silicon ribbon, anticorrosive and antioxidant.

The permission bending radius of this cable is the outside diameter of cable 15 times; Cable permission work maximum temperature is 110 ℃;

The above is the embodiment of the present 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.
