Abstract

The utility model discloses a waterproof wear-resisting variable frequency tensile power cable which is composed of first power line cores, second power line cores, a copper-clad steel armor layer, an alloy lead sheath shielding layer and a silicone rubber outer sheath. The three first power line cores are compressed closely, the three second power line cores are disposed in gaps at outer sides of contact portions of any two first power line cores, and the three first power line cores and the three second power line cores are extruded into a cable core via a water blocking tape wrapped layer. The silicone rubber outer sheath, the alloy lead sheath shielding layer and the copper-clad steel armor layer are extruded onto the cable core from outside to inside. The cable core is provided concentrically with a ground cable core. A ground cable core is disposed in the copper-clad steel armor layer. The waterproof wear-resisting variable frequency tensile power cable is stable in performance, has excellent waterproof, anti-interference and tensile properties, and is stable in current and good in wear resistance.

Description

A kind of waterproof antiwear frequency conversion tension power cable

Technical field

The utility model relates to cable, relates in particular to a kind of waterproof antiwear frequency conversion tension power cable.

Background technology

A distinguishing feature of railway, tunnel, mine, bridge construction is exactly that environment is severe, at this working cable in class place, often will steep in water, in use procedure, also will pull and haul a man, and signal disturbs large, serious wear.The structure of the cable generally using in this class occasion is at present in water resistance, bending property, all very poor on anti-wear performance, and very easily impaired because of the cable sheath of pulling and hauling a man in work progress, useful life is short, the disturbed severity of signal, and electric current is unstable.

Utility model content

According to above-mentioned situation, the utility model object is to provide a kind of waterproof antiwear frequency conversion tension power cable.

Scheme of the present utility model is as follows: a kind of waterproof antiwear frequency conversion tension power cable, it is comprised of power core one, power core two, copper covered steel armour, alloy plumbous cover screen and silicon rubber oversheath, and described power core one is by polyethylene layer, to extrude five copper core conductors to form; Described power core two is that by polyethylene layer, to extrude four sectional areas be that the copper core conductor that the copper core conductor of 35 square millimeters and sectional area are 10 square millimeters forms; Described three power cores one closely compress, and three power cores two are arranged on gap location outside every two power core one contact sites, by waterstop lapping layer, three power cores one are extruded into cable core with three power cores two; Described silicon rubber oversheath, alloy plumbous cover screen and copper covered steel armour are extruded on cable core from outside to inside; A ground core is set in described cable core with one heart; A ground core is set in described copper covered steel armour.

The beneficial effects of the utility model: the utility model stable performance, there is excellent fire resistance characteristic, anti-interference and stretch-proof performance, and current stabilization, resistance to wear is good.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Wherein: 1, copper core conductor; 2, polyethylene layer; 3, waterstop lapping layer; 4, copper covered steel armour; 5, the plumbous cover of alloy screen; 6, silicon rubber oversheath; 7, core.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further;

As shown in Figure 1, a kind of waterproof antiwear frequency conversion tension power cable, it is comprised of power core one, power core two, copper covered steel armour 4, alloy plumbous cover screen 5 and silicon rubber oversheath 6, and described power core one is by polyethylene layer 2, to extrude five copper core conductors 1 to form; Described power core two is that by polyethylene layer 2, to extrude four sectional areas be that the copper core conductor 1 that the copper core conductor 1 of 35 square millimeters and sectional area are 10 square millimeters forms; Described three power cores one closely compress, and three power cores two are arranged on gap location outside every two power core one contact sites, by waterstop lapping layer 3, three power cores one are extruded into cable core with three power cores two; Described silicon rubber oversheath 6, alloy plumbous cover screen 5 and copper covered steel armour 4 are extruded on cable core from outside to inside; A ground core 7 is set in described cable core with one heart; Described copper covered steel armour 4 is interior arranges a ground core 7.

Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection range of the present utility model.
