Abstract

The invention discloses a special double-armor towline cable. The special double-armor towline cable comprises four main cable cores, a grounding cable core, control cable cores, a semiconductive filler layer, an ethylene propylene rubber insulating layer, an aluminum strip armor layer and a chloroprene rubber sheath layer. The four main cable cores are extruded inside the semiconductive filler layer. The grounding cable core is arranged in the center of the interior of the semiconductive filler layer. A thermal insulting layer, a copper strip armor layer and an ultraviolet-proof layer are sequentially arranged between the aluminum strip armor layer and the chloroprene rubber sheath layer in a wrapped mode. The special double-armor towline cable is long in service life, resistant to interference, and capable of being bent cyclically for five million times, is mainly applied to the fields such as aviation, marine and electric power, and has the advantages of being high in high-temperature and low-temperature resistance, and resistant to oil, water and mechanical damage; meanwhile, the ultraviolet shield rate reaches 95.4 percent.

Description

A kind of double armature drag chain special cable

Technical field

The present invention relates to field of cables, relate in particular to a kind of double armature drag chain special cable.

Background technology

At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the fields such as aviation, boats and ships, electric power and tunnel, high and low temperature resistance, waterproof oil resistant, resistance to mechanical damage, antiultraviolet, humidity and chemical resistance aspect to cable require all high especially.Only meet the requirements, the actual service condition of guarantee cable.

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 long service life, resistance to mechanical damage, antiultraviolet, high-low temperature resistant, jamproof double armature drag chain special cable.

The present invention takes following technical scheme to realize: a kind of double armature drag chain special cable, it comprises master core, ground connection core, control core, semiconductive packed layer, ethylene propylene rubber insulated layer, aluminium strip armour and chloroprene rubber sheath layer, described master core is four groups, be extruded in described semiconductive packed layer inside, described semiconductive packed layer inside center is provided with a ground connection core, between described aluminium strip armour and described chloroprene rubber sheath layer, is enclosed with successively thermal insulation layer, copper strips armour, ultraviolet resistant layer.

Described master core is by 9 zinc-plated thread core of aluminum and be wrapped in 9 skinning cortex outside zinc-plated thread core of aluminum and form, and skinning cortex is to be made up of polytetrafluoroethylmaterial material.

Described control core is four, is evenly extruded in described ethylene propylene rubber insulated layer inner, and described control core is made up of copper conductor and the inner insulating layer and the external insulation layer that are wrapped in outside copper conductor, and dielectric layers is to be all made up of polytetrafluoroethylmaterial material.

The present invention has following beneficial effect in sum: this kind of cable applications is extensive, long service life, anti-interference, can experience reversed bending reaches 5,000,000 times, be mainly used in the fields such as aviation, boats and ships, electric power and tunnel the cable using, have that high and low temperature resistance is good, an oil resistant waterproof, resistance to mechanical damage, simultaneously, also possess higher ability and ultraviolet resistance, ultraviolet shielding rate has been reached to 95.4%.

Embodiment

As shown in Figure 1, a kind of double armature drag chain special cable, it comprises master core 1, ground connection core 2, control core 4, semiconductive packed layer 3, ethylene propylene rubber insulated layer 5, aluminium strip armour 6 and chloroprene rubber sheath layer 10, described master core 1 is four groups, be extruded in described semiconductive packed layer 3 inside, described semiconductive packed layer 3 inside center are provided with a ground connection core 2, between described aluminium strip armour 6 and described chloroprene rubber sheath layer 10, are enclosed with successively thermal insulation layer 7, copper strips armour 8, ultraviolet resistant layer 9.

Described master core 1 is by 9 zinc-plated thread core of aluminum and be wrapped in 9 skinning cortex outside zinc-plated thread core of aluminum and form, and skinning cortex is to be made up of polytetrafluoroethylmaterial material.

Described control core 4 is four, is evenly extruded in described ethylene propylene rubber insulated layer 5 inside, and described control core 4 is made up of copper conductor and the inner insulating layer and the external insulation layer that are wrapped in outside copper conductor, and dielectric layers is to be all made up of polytetrafluoroethylmaterial material.

This cable has reached 95.4% to ultraviolet shielding rate; The permission bending radius of this cable is the outside diameter of cable 10 times.

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.
