Description
Technical field
The utility model belongs to power cord technical field, and in particular to a kind of power supply electric wire.
Background technology
Today's society, electric energy have become social development and the essential energy of people's life, the electric energy transmission of power supply
By power cable cable, power cord is the electric wire for transmitting electric current.The mode of usual electric current transmission is point-to-point transmission, usual AC
Power cord is by the wire rod of the higher alternating current of voltage, and this kind of wire rod can produce cable fever, spontaneous combustion since voltage is higher, when
Cable is worn or fracture, the high-voltage electricity of cable inner can produce great danger.
A kind of communication power supply of patent discloses a kind of communication power supply with flame resistant cable (publication number CN203503344U)
With flame resistant cable, its structure includes some insulated wire cores, is arranged to twisted between some insulated wire cores, insulated wire cores
Outside be enclosed with the tight bands of CPP, the gap between the tight bands of CPP and insulated wire cores is filled with PP reticular fibre ropes, and CPP is tight
The periphery of band is enclosed with protective layer.Compared with prior art, the communication power supply of the utility model is passed through with flame resistant cable
Using CPP binding tapes by cable core cladding and PP reticular fibre ropes, can effectively suppress flame on the whole on cable
Prolong combustion, improve the fire resistance at cable conductor, ensure the normal operation of flame resistant cable, reduce the safe to use hidden of cable
Suffer from, but the utility model cable strength and heat resistance, service life are low.
Therefore the power supply electric wire that a kind of intensity is high, heat-resisting effect is good, fire-retardant and service life is grown is needed.
Utility model content
The purpose of this utility model is to provide a kind of power supply electric wire, to solve existing wire rod fever, easily spontaneous combustion, mill
The problem of damage or fracture, service life is short.
The utility model provides following technical solution：
A kind of power supply electric wire, including multiple cable cores, are equipped with cushion between the cable core, on each cable core
Insulating layer is equipped with, the insulating layer periphery is equipped with shielded layer, filler, institute are equipped between the shielded layer and the insulating layer
Filler is stated to be internally provided with along the symmetrical cordage in cable core axle center, the shielded layer is equipped with refractory layer, the refractory layer with
The contact surface of the shielded layer is equipped with flame-retardant layer equipped with some along the equally distributed trapezoidal groove of axis, the refractory layer,
The flame-retardant layer is equipped with armor, and the armor is equipped with protective case.
Preferably, the protective case is equipped with some along the equally distributed arc bump of axis, the convex block and the guarantor
Sheath is integrally formed, increases the surface strength and frictional force of cable.
Preferably, the cordage is made of carbon fiber and acrylic rubber material, and the stretching for increasing cable inner is strong
Degree.
Preferably, the cushion is made of fluorubber material, and elasticity is high heat-resisting good, protects cable core.
Preferably, the filler is glass cord.
Preferably, the armor is made of stainless steel material, and protection cable will not be destroyed by extraneous mechanical force, changed
Learn gas attack.
The beneficial effects of the utility model are：
1. the utility model overall structure is simple, it is easy to make and promotes.
2. cable is equipped with refractory layer and flame-retardant layer, possess good heat-proof combustion-resistant effect.
3. cable is equipped with the intensity of cordage, armor and protective case comprehensive guarantee cable from inside to outside.
