The utility model solves the technical scheme that its technical problem adopts:
A kind of communication truck moves cable, comprise cable conductor, conductive layer, insulating barrier and fixed bed, described conductive layer is coated on cable conductor outside by fixed bed, described insulating barrier is wrapped in conductive layer outside, described conductive layer comprises conductive bodies layer, described conductive bodies layer is provided with some raised items being parallel to cable conductor axis, between some described raised items, is filled with fire proofing material; The outside of described insulating barrier is also provided with pvc sheath layer, is provided with multiple polyolefin elastomer between described pvc sheath layer and insulating barrier; Cable core comprises some independent cable cores being coated with screen, and the center of some described cable conductors is provided with steel wire rope.
Described cable conductor by ground wire, video line, many signal cables, feed cable is stranded is formed.
Between described conductive layer and fixed bed, be provided with flame-retardant layer, described flame-retardant layer is made up of the mesh grid of multilayer asbestos.
This conductive layer wrappedly to form by stranded copper wire is oblique outside flame-retardant layer.
Described fixed bed is aeroge, and described cable conductor is fixed in aeroge.
Described fire proofing material is asbestos.
Described insulating barrier is Teflon Withstand voltage layer.
The beneficial effects of the utility model are:
The first, the utility model is connected with ground wire by arranging conductive layer, when being struck by lightning for the first time, by most of electric energy guiding ground wire, can prevent the damage of electrical appliance to a certain extent.
The second, in cable, Teflon Withstand voltage layer is provided with, Teflon is polytetrafluoroethylene again, there is excellent heat-resisting and low temperature tolerance characteristics, all deformation can not be there is under high temperature severe cold, there is good compressive property, and polyolefin elastomer is provided with between pvc sheath layer and Teflon Withstand voltage layer, there is the effect of good buffering, dispersive pressure, and the outer wall of cable can quick-recovery soon.
Three, aerogel layer of the present utility model can be fixed wire, alleviates the weight of cable itself, also when conductive layer meets with electric shock generation thawing, can carry out heat insulation and fire-retardant, prevent wire generation thawing from causing power-off simultaneously.
Four, bulk asbestos braid of the present utility model also can carry out certain fire-retardant and heat insulation.
Five, the fire-retardant asbestos between raised item of the present utility model can prevent conductive line surfaces from burning, and the high temperature that preventing burns produces causes the thawing of conductive layer.
Six, place steel cable in cable conductor, have stronger stretching resistance, when wiring and the take-up of cable, the damage pulling and cable is brought can be effectively reduced, when being connected to the equipment free suspension of eminence, effectively can share the deadweight of cable, effectively can extend the life-span of cable.
