Description

A kind of multicore cross-linking radiation aluminium alloy cable

Technical field

The utility model relates to a kind of multicore cross-linking radiation aluminium alloy cable.

Background technology

At present, along with developing rapidly of national economy, cable is widely used in various power station, such as, in the various field such as nuclear power station, thermal power station etc. and subway station, power plant, skyscraper building, military installations, oil platform, therefore, people to the quality of cable and the requirement of function also more and more higher; Common cable adopts Halogen material if PVC insulating barrier is as restrictive coating usually, its structure is not tight, it is crucial that once breaking out of fire BLV cable fire can produce a large amount of dense smoke, rescue personnel and the disaster-stricken common people often to be bottled up even death by suffocation by smog, rescue work is made to be difficult to carry out, rescue efficiency is low, and meanwhile, the burning of Halogen material can produce again a large amount of toxic gases and atmosphere pollution; In addition, single on current cable feature also needs to change, and therefore produces a kind of rational in infrastructure and the cable that can overcome above-mentioned shortcoming seems very urgent.

Summary of the invention

The purpose of this utility model is to overcome above-described shortcoming, provides a kind of and does not produce toxic gas when burning, and all has the cable of larger usefulness for rescuing and preventing and remedying pollution.

For achieving the above object, concrete scheme of the present utility model is as follows: a kind of multicore cross-linking radiation aluminium alloy cable, include at least two conductor groups, each described conductor group all comprises a cable conductor, and described each cable conductor is all coated with the first insulator layer;

Also include belting layer, described belting layer wraps up all conductor groups; Also include inner cushion layer, described inner cushion layer wraps up described belting layer; Also include steel wire armor layer, described steel wire armor layer wraps up described inner cushion layer; Also include low smoke, zero halogen pe sheath, described low smoke, zero halogen pe sheath wraps up described steel wire armor layer.

Wherein, described first insulator layer is irradiation low-smoke non-halogen flame-retardant polyethylene layer.

Wherein, described inner cushion layer is low-smoke non-halogen flame-retardant polyethylene layer.

Wherein, the quantity of described conductor group is four.

Wherein, also include the second insulator layer be located between low smoke, zero halogen pe sheath and described steel wire armor layer, the pipe arm of described second insulator layer is provided with multiple dashpot vertically, described dashpot interval is arranged.

Wherein, the edge of described dashpot is provided with sawtooth.

The beneficial effects of the utility model are: include at least two conductor groups, and each described conductor group all comprises a cable conductor, and described each cable conductor is all coated with the first insulator layer; Also include belting layer, described belting layer wraps up all conductor groups; Also include inner cushion layer, described inner cushion layer wraps up described belting layer; Also include steel wire armor layer, described steel wire armor layer wraps up described inner cushion layer; Also include low smoke, zero halogen pe sheath, described low smoke, zero halogen pe sheath wraps up described steel wire armor layer; By setting like this, realizing the effect of low smoke, zero halogen, not producing toxic gas when burning, all have larger usefulness for rescuing and preventing and remedying pollution; Aluminium alloy cable has higher electrical property, promotes practicality of the present utility model.

Embodiment

Being described in further detail the utility model below in conjunction with the drawings and specific embodiments, is not that practical range of the present utility model is confined to this.

As shown in Figure 1 to Figure 2, a kind of multicore cross-linking radiation aluminium alloy cable described in the present embodiment, includes at least two conductor groups, and each described conductor group all comprises a cable conductor 1, and described each cable conductor 1 is all coated with the first insulator layer 2; Also include belting layer a, described belting layer a wraps up all conductor groups; Also include inner cushion layer 3, described inner cushion layer 3 wraps up described belting layer a; Also include steel wire armor layer 4, described steel wire armor layer 4 wraps up described inner cushion layer 3; Also include low smoke, zero halogen pe sheath 5, described low smoke, zero halogen pe sheath 5 wraps up described steel wire armor layer 4.By setting like this, realizing the effect of low smoke, zero halogen, not producing toxic gas when burning, all have larger usefulness for rescuing and preventing and remedying pollution; Aluminium alloy cable has higher electrical property, promotes practicality of the present utility model.Described belting layer a by all conductor group parcels together, prevents loose.Described steel wire armor layer 4 can effectively increase cable strength and hardness, extends the useful life of cable.

A kind of multicore cross-linking radiation aluminium alloy cable described in the present embodiment, described first insulator layer 2 is irradiation low-smoke non-halogen flame-retardant polyethylene layer; Irradiation low-smoke non-halogen flame-retardant polyethylene layer increases the effect of the utility model fire protection flame retarding, low cigarette of low pollution when burning further.

A kind of multicore cross-linking radiation aluminium alloy cable described in the present embodiment, described inner cushion layer 3 is low-smoke non-halogen flame-retardant polyethylene layer; Irradiation low-smoke non-halogen flame-retardant polyethylene layer increases the effect of the utility model fire protection flame retarding, low cigarette of low pollution when burning further.

A kind of multicore cross-linking radiation aluminium alloy cable described in the present embodiment, the quantity of described conductor group is four; The conductor number of four is the more rational number of conductors that can bear under Stability Analysis of Structures prerequisite.

A kind of multicore cross-linking radiation aluminium alloy cable described in the present embodiment, also include the second insulator layer b be located between low smoke, zero halogen pe sheath 5 and described steel wire armor layer 4, the pipe arm of described second insulator layer is provided with multiple dashpot b1 vertically, and described dashpot b1 interval is arranged.A kind of multicore cross-linking radiation aluminium alloy cable described in the present embodiment, the edge of described dashpot b1 is provided with sawtooth.When dashpot b1 bends, sawtooth can effectively increase bending effect, prevents cable from breaking.

The above is only a preferred embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the protection range of the utility model patent application.
