Through the above design, the rectangular cable can achieve a good waterproof effect and a function of reducing interferences among the rectangular wire core conductors is possessed.

Description

A kind of rectangular cable

Technical field

The utility model power transmitting device technical field, refers to a kind of rectangular cable especially.

Background technology

Conductor thread core and the insulating barrier of existing transferring electric power rectangular cable are generally circular configuration, conductor thread core through strand to or stranding, shielding and sheath.The feature of this rectangular cable is that inductance is relatively large, and electric capacity is relatively little, and inductance has that filtering exchanges with resistance, the effect of perfectly straight stream; Electric capacity has the logical effect that exchanges, hinders direct current of filtering.And this rectangular cable cannot meet eliminate the impact of clutter on telecommunication apparatus under high magnetic compatible environment.For overcoming this difficulty, can guarantee that telecommunication apparatus electric power transfer, under high magnetic compatible environment, bears outside electromagnetic interference, reduce the rectangular cable of miscellaneous equipment electromagnetic interference is developed.

But, people's routine work, life, productive power amount increase day by day, therefore also increasing for transmission of electricity rectangular cable use amount, cable use occasion becomes increasingly complex, such as wet environments such as harbour, harbour, hydroelectric station, reservoir, tunnels, in these situations, rectangular cable, except possessing anti-mechanical damage function, also should possess good fire resistance characteristic.Existing rectangular cable sheath is owing to lacking good permeability resistance, and water is easy to penetrate into rectangular cable inside, and the insulating barrier of parcel core is caused to potential destruction, affects the useful life of rectangular cable, when serious, can cause rectangular cable cisco unity malfunction.

Utility model content

The utility model proposes a kind of rectangular cable, solved the poor problem of rectangular cable water resistance of the prior art.

The technical solution of the utility model is achieved in that

A kind of rectangular cable, comprising:

At least one rectangular lines core conductor being formed by 12～36 one metal wires;

Insulating barrier, is arranged on outside rectangular lines core conductor;

The sheath that has been used for waterproof, corrosion-resisting function, is arranged on outside insulating barrier, and is also provided with packed layer between sheath and insulating barrier;

Armour, is arranged on outside sheath;

For the outer jacket shielding, be arranged on outside sheath.

As further technical scheme, the filler of packed layer is waterproof rope.

As further technical scheme, armour is zinc-plated steel band armour.

As further technical scheme, sheath is polyolefin sheath.

As further technical scheme, outer jacket is PVC thermoplastic plastic layer, and its thickness is for being not less than 5 millimeters.

The insulating barrier being arranged on outside rectangular lines core conductor can effectively reduce the interference between each rectangular lines core conductor; Be used for the sheath of waterproof, corrosion-resisting function, be arranged on outside insulating barrier; Between sheath and insulating barrier, be provided with packed layer, can effectively there is waterproof effect; Sheath is outside equipped with the armour of the wear-resisting and anti-mechanical stretching of water; Armour is also provided with outer jacket outward, by above-mentioned design, can make rectangular cable reach good waterproof effect, and has the interference function reducing between each rectangular lines core conductor.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the cross sectional representation of the utility model embodiment;

In figure:

1, rectangular lines core conductor; 2, insulating barrier; 3, packed layer 4, sheath; 5, armour; 6, outer jacket.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, a kind of rectangular cable the utility model proposes, comprising:

A kind of rectangular cable, comprising:

At least one rectangular lines core conductor 1 being formed by 12～36 one metal wires;

Insulating barrier 2, is arranged on outside rectangular lines core conductor 1;

The sheath 4 that has been used for waterproof, corrosion-resisting function, is arranged on outside insulating barrier 2, and is also provided with packed layer 3 between sheath 4 and insulating barrier 2;

Armour 5, is arranged on outside sheath 4;

For the outer jacket 6 shielding, be arranged on outside sheath 4.

Be arranged on the interference that insulating barrier 2 outside rectangular lines core conductor 1 can effectively reduce 1 of each rectangular lines core conductor; Be used for the sheath 4 of waterproof, corrosion-resisting function, be arranged on outside insulating barrier 2; Between sheath 4 and insulating barrier 2, be provided with packed layer 3, can effectively there is waterproof effect; Sheath 4 is outside equipped with the armour 5 of the wear-resisting and anti-mechanical stretching of water; Armour 5 is outer is also provided with outer jacket 6, by above-mentioned design, can make rectangular cable reach good waterproof effect, and has the interference function that reduces by 1 of each rectangular lines core conductor.

As further technical scheme, the filler of packed layer 3 is waterproof rope.

The filler of packed layer 3 is many waterproof ropes, and waterproof rope is a kind of rope shape materials being composited by polyester fiber, adhesive and rapid expanding water-absorbing resin, and it can expand rapidly after meeting water, stops the further infiltration of water.

As further technical scheme, armour 5 is zinc-plated steel band armour.

The armour 5 that the preferred zinc-plated steel band of armour 5 is made, has the effect of waterproof antiwear and anti-mechanical stretching.

As further technical scheme, sheath 4 is polyolefin sheath.

Sheath 4 is polyolefine material, can play waterproof, etch-proof effect, has good toughness and insulating properties.

As further technical scheme, outer jacket 6 is PVC thermoplastic plastic layer, and its thickness is for being not less than 5 millimeters.

Outer jacket 6, for thickness is to be not less than the PVC thermoplastic plastic layer of 5 millimeters, has good physically encapsulation and good resistance to wear.
