Can meet the needs of environment friendly.
Technical solutions adopted by the utility model to solve the above technical problems are as follows:
A kind of warp resistance environmental protection fire resistant flame retardant high-speed rail jumper cable, includes power core conductor, conductor from the inside to the outside
Shielded layer, insulating layer, insulation screen, metal screen layer, restrictive coating；The power core conductor, which is that tin plating soft copper is twisted, to be led
Body, the insulating layer be it is ethylene propylene rubber insulated, the metal screen layer includes metal shuffling layer and is coated on outside metal shuffling layer
The fiber mixed protection layer of side, the metal shuffling layer are the mixed strand braiding structure of zinc plated mild carbon steel silk and tin metal copper wire,
The fiber mixed protection layer is the mixed strand braiding structure of rubberized cord and aramid fiber, and the restrictive coating is low-smoke non-halogen flame-retardant
Fire-resistant rubber material.
Five class tinned copper wire lay configurations can be used in the power core conductor.
The insulating layer is the ethylene propylene rubber insulated layer of low-smoke non-halogen flame-retardant environmental protection.
The metal shuffling layer uses the mixed strand braiding structure of zinc plated mild carbon steel silk and tin metal copper wire, steel wire and copper wire
Twisted ratio is 1:7.
The fiber mixed protection layer uses the mixed strand braiding structure of rubberized cord and aramid fiber, rubberized cord and aramid fiber
Fiber is twisted on the contrary, monofilament ratio is identical.
The restrictive coating is extruded using low smoke halogen-free fire retardant fire resistant rubber material and is crosslinked.
The utility model have it is following the utility model has the advantages that
(1) power core conductor of the utility model is tangled structure again using tin-coated copper tow, improves the drawing of cable core
It stretches and bending property, adopts the structure the fatigue performance of certifiable cable core, ensure that the high life of electric power transfer unit；
(2) power core conductor insulation layer of the utility model extrudes crosslinking using low flue unhalogen flame-retarded ethylpropyl rubber material
It forms, the insulated electro tree and water tree that can inhibit in use process generate, and effectively improve product insulation performance；
(3) metal screen layer of the utility model uses zinc plated mild carbon steel silk and the mixed twisted of tin metal copper wire knits knot
Structure, the addition of zinc plated mild carbon steel silk improve the warp resistance performance of shielded layer.This structure can guarantee that cable has in use
Standby high anti-fatigue performance guarantees that shielded layer is not broken when high-speed rail EMU high speed is excessively curved, guarantees well connecing for electric appliance original part
Ground greatly improves the service life and safety of product.
(4) the fiber mixed protection layer of the utility model uses the mixed strand braiding structure of rubberized cord and aramid fiber,
Relative sliding will not be generated between the shielded layer and sheath of the certifiable cable of this structure, metal screen layer is protected, simultaneously
The service life for effectively improving cable shield improves the security performance of product.Metal screen layer is in conventional high-pressure jumper cable
Proof copper-wire braided shielding construction, and to shielded layer unprotect, occur fracture of wire broken string phenomenon afterwards for a period of time in train operation, to electricity
The ground connection of gas equipment does not have protective effect, influences vehicle driving safety.
In conclusion the utility model has long service life, bending radius is small, and insulation performance is good, fatigue performance is good,
The advantages that environmentally friendly, fire-retardant, fire resisting, can be widely applied to " revive number ", " Harmony " high-speed rail high pressure wire jumper or subway high pressure
Wire jumper.
