Abstract

The invention discloses a high strength mobile tensile resistant and fire resistant cable which is composed of power wire cores, a shielding wire core, a fiberglass tape winding and wrapping layer, a conductor shielding layer, a copper cap steel armor layer and an outer sheath, wherein the power wire cores are formed by sequentially pressing and wrapping an insulation shielding layer, a cushion lining layer and a steel tape armor layer from inside to outside on an aluminum alloy stranded conductor; the shielding wire core is formed by pressing and wrapping the insulation shielding layer and the cushion lining layer from inside to outside on a silver plated copper wire stranded conductor; the fiberglass tape winding and wrapping layer presses and wraps two power wire cores and one shielding wire core to form a cable core; the gap of the cable core is filled with a fire resistant mica tape fill layer; the cable core is sequentially provided with the conductor shielding layer, the copper cap steel armor layer and the outer sheath from inside to outside. The high strength mobile tensile resistant and fire resistant cable is simple in structure design, stable in performance, high in structural strength, high temperature resistant, fire resistant, suitable for being moved and pulled on the ground, tensile resistant, tearing resistant and wear resistant.

Description

A kind of high strength mobile tensile fire-resisting cable
Technical field
The present invention relates to cable, relate in particular to a kind of high strength mobile tensile fire-resisting cable.
Background technology
China's economic growth continuously and healthily, for cable products provides the huge market space, and the departments such as industrial and mining enterprises, energy traffic need increasing moving control cable, moving control cable often pulls in practice, movement has high requirement to the anti-tear resistance to wear of cable, and traditional cable cannot meet above-mentioned requirements.And China is the big country of a rich coal resources, coal is one of important energy of China, along with the continuous demand of expanding economy to electric power, drive coal high speed development also, also driven the cable development of using for coal mining, along with scientific and technological development, for the more and more high-powers that trend towards of equipment of the resource that cuts coal, the electric wire that has therefore driven equipment connection to use trends towards high electric pressure development.And the mobile fire-resisting cable that the mobile power supply equipment of the electric pressure 8.7/10kV rank of using for outdoor mining industry is in the market used mainly depends on import.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide a kind of high strength mobile tensile fire-resisting cable.
The solution of the present invention is as follows: a kind of high strength mobile tensile fire-resisting cable, it is made up of power core, shielding core, glass fibre belt lapping layer, conductor shield, copper covered steel armour and oversheath, and described power core is to be from inside to outside extruded in successively on aluminium alloy stranded conductor and to form by insulation screen, pad underlayer, steel-tape armouring layer; Described shielding core is to be from inside to outside extruded on silver-gilt copper wire stranded conductor and to be formed by insulation screen and pad underlayer; Described glass fibre belt lapping layer extrudes into cable core by two power cores with a shielding core; Described cable core gap-fill has fire-resistant isinglass belt packed layer; Cable core is from inside to outside provided with conductor shield, copper covered steel armour and oversheath outward successively.
Described oversheath 9 adopts ceramic pvc material.
Beneficial effect of the present invention: structural design of the present invention is simple, stable performance, structural strength is high, high temperature resistant, prevents fires, and is applicable to move on the ground pull use, and tension, anti-tear, has resistance to wear.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, a kind of high strength mobile tensile fire-resisting cable, it is made up of power core, shielding core, glass fibre belt lapping layer 6, conductor shield 7, copper covered steel armour 8 and oversheath 9, and described power core is to be from inside to outside extruded in successively on aluminium alloy stranded conductor 1 and to form by insulation screen 2, pad underlayer 3, steel-tape armouring layer 4; Described shielding core is to be from inside to outside extruded on silver-gilt copper wire stranded conductor 5 and to be formed by insulation screen 2 and pad underlayer 3; Described glass fibre belt lapping layer 6 extrudes into cable core by two power cores with a shielding core; Described cable core gap-fill has fire-resistant isinglass belt packed layer 10; Cable core is from inside to outside provided with conductor shield 7, copper covered steel armour 8 and oversheath 9 outward successively.
Described oversheath 9 adopts ceramic pvc material.
Although above the specific embodiment of the present invention 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 invention and change and revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection scope of the present invention.
