Abstract
The utility model discloses an oil-resistant waterproof corrosion-resistant double-shielding control cable for a mine. The cable comprises a main wire core, a control wire core, a belt wrapping layer, an insulation layer, a shielding layer, a waterproof layer and a protective sleeve. An inner shielding layer is arranged between the belt wrapping layer and the insulation layer; the inner shielding layer is formed by braiding a nickel-clad copper aluminum alloy filament and wrapping silicone rubber; a thermal insulation layer is wrapped between the shielding layer and the waterproof layer; a ground wire core and the control wire core are wrapped by the thermal insulation layer; and the protective sleeve is formed by wrapping a steel wire added with a conserving agent and an oil-resistant agent by use of a butyronityile sheath. The cable provided by the utility model is good in conductive performance and high in anti-dragging performance, bending resistance and mechanical wear resistance, is mainly applied to such fields as coal mines, communications, chemical petroleum and the like, is good in shielding effects and high in oil resistance and waterproofing performance, and at the same time is excellent in corrosion resistance.
Description
Technical field
The utility model belongs to field of cables, relates in particular to the anticorrosive double shield control cables of oil resistant waterproof for a kind of colliery.
Background technology
At present, along with developing rapidly and the raising day by day of scientific and technological level of Chinese national economy, accelerated the growth of cable consumption, equally the quality requirement of cable has also constantly been improved.Such as the cable using for fields such as collieries, because operating environment is more special, common cable is difficult to meet the requirement of using.Actual conditions require the cable using to propose higher requirement for everyways such as insulating properties, tensile strength, oil resistant water proofing property, wear-resisting flame resistance, shielding properties and corrosion resistancies.Only meet the requirements, could improve in these fields the fail safe while manufacturing.
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 tensile strength that conducts electricity very well, insulate, oil resistant waterproof, the anticorrosive double shield control cables of oil resistant waterproof for anti-interference and erosion-resisting colliery.
The utility model takes following technical scheme to realize: the anticorrosive double shield control cables of oil resistant waterproof for a kind of colliery, it comprises master core, control core, belting layer, insulating barrier, screen, watertight composition and protective sleeve, between described belting layer and described insulating barrier, be provided with internal shield, described internal shield is to be formed by nickel-clad copper aluminum-alloy wire the braiding of wrapped silicon rubber, between described screen and watertight composition, wrap up thermal insulation layer, described thermal insulation layer internal package ground connection core and described control core, described master core, control core, ground connection core is respectively two, four, one, described protective sleeve is to add anticorrosive, the fine sheath of steel wire outsourcing fourth of oil-proof composition.
Described watertight composition is comprised of three layers of waterproof outer layer, waterproof internal layer and water accepting layers, and described thermal insulation layer material is to add the ceramic fibre of semi-conducting material.
Described ground connection core is that the annealed copper aluminum-alloy wire stranded 720 ° of braidings to the right by electroplate form, and described earth connection core diameter is 0.8 millimeter.
The utlity model has in sum following beneficial effect: this cable conduction performance is good, high temperature resistant, anti-pulling, resistance to bending, resistance to mechanical wear, is mainly used in the fields such as colliery, communication, chemical petroleum, shield effectiveness is good, and oil resistant waterproof also possesses good corrosion resistance simultaneously.
