Description
Technical field
The utility model is related to field of cable technology, more particularly to a kind of ethylene propylene rubber insulated flame-proof polyvinyl chloride sheath electricity
Power cable.
Background technology
Cable, as transmitting electric power and propagating the carrier of information, serves huge effect in the development of the national economy, with
The fast development of the quickening of urbanization process, electric power transmission and communication so that requirement more and more higher of the people to electric wire,
The characteristics of not requiring nothing more than cable there is safety and environmental protection, and with relatively low cost.
Common cable is some copper core outsourcing insulating layer coatings, and outer shape is circle, and this round cable is a lot
Occasion is obtained for and is widely applied, but the shortcoming of round cable is to work as the electrical equipment connection being used as between mobile appliance equipment
When, it is not easy to bend, moves；And, the performance such as existing cable oil resistant, wear-resisting is preferable not enough, is further improved.
Utility model content
It is ethylene propylene rubber insulated fire-retardant the utility model proposes one kind in order to solve technical problem present in background technology
Polyvinyl chloride boot power cable, effect is good.
A kind of ethylene propylene rubber insulated flame-proof polyvinyl chloride sheath power cable, including cable core portion and cable core portion is wrapped in successively
On inner liner, braiding layer, screen layer, ethylene propylene rubber insulated layer；Cable core portion includes three wires, is filled out between wire and inner liner
Filled with filler；
What cable was spaced along its length is provided with multiple flat zones, and three wires positioned at flat zone equidistantly and are arranged
Put；Three wires positioned at non-flat area are arranged in parallel, the axis distribution triangular in shape of three wires.
Preferably, wire includes core, belting layer, pvc sheath layer.
Preferably, be provided with ethylene propylene rubber insulated layer it is multiple extend longitudinally along the cable by filament constitute it is anti-
Drawstring.
Preferably, multiple tension ropes are uniformly distributed along the circumference of cable.
Preferably, the inner circumferential surface of braiding layer and outer peripheral surface are coated with flame retardant coating.
Preferably, also it is enclosed with metal level on the ethylene propylene rubber insulated layer of flat zone.
Preferably, metal level is provided with the mounting hole for being connected with the external world.
In the utility model, by setting multiple flat zones, it is easy to cable by small space, reduces the mill to cable
Damage, using more convenient.Using ethylene propylene rubber insulated layer, the performance such as cable oil resistant, solvent resistant, resisting impregnation paint, wear-resisting is improved, carried
The service life of cable high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view of Fig. 1；

Mutual combination；Below with reference to the accompanying drawings and in conjunction with the embodiments the utility model is elaborated.
Reference picture 1-4：
The utility model proposes a kind of ethylene propylene rubber insulated flame-proof polyvinyl chloride sheath power cable, including cable core portion and
Inner liner 5, braiding layer 6, screen layer 7, ethylene propylene rubber insulated layer 9 in cable core portion are wrapped in successively；Led including three in cable core portion
Line, is filled with filler 4 between wire and inner liner 5.
What cable was spaced along its length is provided with multiple flat zones, equidistant side by side positioned at three wires of flat zone P
Arrangement；Three wires positioned at non-flat area P are arranged in parallel, the axis distribution triangular in shape of three wires；It is steady using triangle
Qualitative principles so that three wires are not easily shifted, can effectively lift the mechanical strength of cable.
The shielding properties and interference free performance of cable are improve using screen layer；Electricity is improved using ethylene propylene rubber insulated layer 9
The performance such as the oil resistant of cable, solvent resistant, resisting impregnation paint, wear-resisting.
In the present embodiment, wire includes core 1, belting layer 2, pvc sheath layer 3；Improve wire insulating properties and
Fire resistance.
In the present embodiment, be provided with 9 layers of EP rubbers sheath it is multiple extend longitudinally along the cable by filament group
Into tension rope 8；Improve the tensile property of cable.
In the present embodiment, multiple tension ropes 8 are uniformly distributed along the circumference of cable；Tensile property can effectively be played.
In the present embodiment, the inner circumferential surface of braiding layer 6 and outer peripheral surface are coated with flame retardant coating；Further carry
The fire resistance of cable high.
In the present embodiment, metal level 10 is also enclosed with the ethylene propylene rubber insulated layer of flat zone P, it is to avoid damage electricity
Cable.
In the present embodiment, metal level 10 is provided with the mounting hole 11 for being connected with the external world；It is easy to electricity using mounting hole 11
Cable is connected with the external world, improves cable using effect.
The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any one skilled in the art in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its utility model design are subject to equivalent or change, should all cover in protection model of the present utility model
Within enclosing.
