The in-line power of the lead line, industrial and mining enterprises stood and the submarine transmission line of crossing river and sea.In power circuit, shared by cable
Proportion just gradually increase.Power cable is in the basic routing line of electric system transmitting and distribute the electricity of high-power power
Cable product, including 1-500KV and any of the above voltage class, the power cable of various insulation.
Power cable gram is defined as：The aggregate consisted of following parts；One or more insulated wire cores and they are each
From the clad that may have, total protective layer and outer jacket, cable can also have the additional conductor not insulated.Existing cable
When in use by rolling cable can be caused to be damaged for a long time.So to remain crushing resistance poor for power cable, it is easy damage
It is bad, the technical problems such as safety cannot ensure.
Invention content
The technical problem to be solved by the present invention is to：It is proposed that a kind of durable type power cable, reasonable design are hardly damaged,
Securely and reliably.
In order to solve the above technical problems, one aspect of the present invention is：A kind of durable type power cable, including
Three cable cores and sheath body, are installed with a separator in the sheath body, and the section of the separator is to fall Y-shaped, the separator
Three identical cable core rest areas will be separated into sheath body, three cable cores are respectively arranged on cable core rest area；
The cable core includes cable core conductor, and the periphery of the cable core conductor closely coats one layer of insulating lacquer layer, the insulation
Closely one layer of anti-corrosion enamelled coating of cladding, the periphery of the anti-corrosion enamelled coating closely coat one layer of rubber insulation for the periphery of enamelled coating；
The sheath body includes the first glass fiber mesh layer, nonwoven layer, the second glass fiber mesh layer, shielded layer and oversheath
Layer, the nonwoven layer are located at the outside of first glass fiber mesh layer, and second glass fiber mesh layer is located at the nothing
The outside of woven fabric layer, the shielded layer are located at the outside of second glass fiber mesh layer, and the external protection is located at the screen
Cover the outside of layer；
There is filler between the cable core and the sheath body.
It further says, the rubber insulation is nitrile rubber insulation layer.
It further says, the shielded layer is metal net layer.
It further says, the filler is 3M electric insulation resins.
It further says, the separator is silica gel separator.
It further says, the external sheath layer is to prevent puncturing rubber layer.
Beneficial effects of the present invention at least have the following：
One, the present invention includes three cable cores and sheath body, and a separator is installed in sheath body, and the section of separator is to fall " Y "
Type, separator will be separated into three identical cable core rest areas in sheath body, three cable cores are respectively arranged on cable core rest area, in sheath body
Interior setting separator, the fixing of reinforcement cable, rugged construction, reasonable design, securely and reliably, extend cable uses the longevity
Life is conducive to save cost；
Two, the present invention uses multilayer dielectric layer, and 3M electric insulation resins are filled between cable core, makes insulating performance of cable
More preferably；
Three, the present invention uses layer glass fiber web layer, itself has extraordinary insulation performance, simultaneously because netted
Special construction, and have the effect of heat dissipation, cable is protected, the service life of cable is extended.
Description of the drawings
