Abstract

The invention relates to an electric wire/cable, which comprises a lead with an insulator. Reinforcing ribs are wound on the lead; and a gap is reserved between adjacent reinforcing ribs. Compared with a common electric wire/cable, the electric wire/cable provided by the invention has higher wear resistance when being drawn and pulled, the gaps among the reinforcing ribs realize stronger radiation capability of the electric wire/cable, and the problem of constraint of a steel strip or a steel mesh is solved so that the electric wire/cable is easier to bend; and moreover, the electric wire/cable is more convenient to pave at a bent position, the metal usage amount is reduced and the cost is lowered.

Description

A kind of electric wire

Technical field

The present invention relates to a kind of electric wire, belong to technical field of electricity.

Background technology

At present, general electric wire generally comprises lead, sheath, armour and outer jacket from inside to outside, and the common wiring cable does not have armour; The general electric wire that does not have an armour in use; Often occur galling, revealing skin, leak current fault, cause the lead of electric wire also very new, and sheath is aging in advance; Directly have influence on the useful life and the personal safety of electric wire, cause the wasting of resources.

Electric wire installs the purpose of armour additional except mechanical protections such as enhancing tensile strength, compression strength increase the service life; The electric wire of armouring has certain external force resistance performance; The armouring of electric wire is processed with steel band or steel wire usually; The steel-tape armouring electric wire normally is wrapped in around the lead two edge laps with two-layer at least steel band is vertical.

Because steel-tape armouring electric wire seamless unoccupied place coated steel band around the lead, therefore the thermal diffusivity of this electric wire is poor, and electric wire is when bending, and the insulating barrier of lead is pierced through by steel band easily, causes the electric leakage accident; Steel wire armor wire cable is around lead, to coat the layer of steel wire net, causes the cost of this electric wire high, the complex process of production.More than two kinds of electric wires receive the constraint of steel band or steel wire, cause not flexible, unusual difficulty when corner is laid.

Summary of the invention

The technical problem that the present invention will solve is to above deficiency, provides a kind of cost low, wear-resistant, easy bending, the electric wire that heat-sinking capability is strong.

For solving above technical problem, the technical scheme that the present invention adopts is following: a kind of electric wire is characterized in that: said electric wire comprises the lead with insulator, is wound with reinforcement on the lead, has the gap between the adjacent reinforcement.

Adopt above technical scheme, than general electric wire, more wear-resisting when dilatory; Having the gap between the reinforcement makes the heat-sinking capability of electric wire stronger; And overcome the problem that receives the constraint of steel band or steel wire, and crooked more easily, convenient when having the position laying wire cable of bending; Reduce the use amount of metal, reduced cost.

Further improvement as technique scheme:

Said reinforcement is the reinforcement that plastics are processed.

Said reinforcement comprises two-layer, the protective layer that skin is processed for plastics, and internal layer is an intensive aspect.

Reinforcement has plastic protective layer, can reduce the damage to lead.

Said intensive aspect is the intensive aspect that steel wire is processed.

Said intensive aspect is the thread intensive aspect of nylon.

Adopt steel wire, nylon wire equal strength than higher material intensive aspect, can make the intensity of reinforcement higher.

Be provided with sheath between said reinforcement and the lead.Can guardwire, make the security performance of electric wire higher.

The outside of said reinforcement is provided with outer jacket.Can effectively protect electric wire on the one hand, make cable more attractive in appearance on the other hand.

The present invention adopts above technical scheme, compared with prior art, has the following advantages:

(1) adopt above technical scheme, than general electric wire, more wear-resisting when dilatory; Having the gap between the reinforcement makes the heat-sinking capability of electric wire stronger; And overcome the problem that receives the constraint of steel band or steel wire, and crooked more easily, convenient when having the position laying wire cable of bending; Reduce the use amount of metal, reduced cost.

(2) reinforcement has plastic protective layer, can reduce the damage to lead; Adopt steel wire, nylon wire equal strength than higher material intensive aspect, can make the intensity of reinforcement higher.

(3) sheath can guardwire, makes the security performance of electric wire higher.

(4) outer jacket can effectively be protected electric wire on the one hand, makes electric wire more attractive in appearance on the other hand.

Below in conjunction with accompanying drawing and embodiment the present invention is described further.
