Description
Technical field
The utility model relates to a kind of cable, particularly a kind of water-proof cable.
Background technology
In recent years, the track traffic of cities in China and the shipping industry development of coastal area rapidly, make the demand of all kinds of extraordinary feeder cable increase rapidly.As in magnetic suspension system, the use length of cable is about 30 times of magnetic suspension line length, and use amount is large, accounts for about 3% of magnetic suspension train gross investment.Because extraordinary feeder cable environment for use is special, particular/special requirement is all had to performances such as the waterproof of cable, fire-retardant, high temperature resistant, tensile strength, external Nike Sen Dengjijia big companies is only had to produce in the world at present, although domestic like product cable insulation, protective cover material fire-retardant and high temperature resistant in substantially can meet instructions for use, its waterproof technique still has larger gap compared with abroad.
Utility model content
The purpose of this utility model is to provide a kind of waterproof feeder cable for magnetic suspension train, make it have good waterproof, fire-retardant, resistance to elevated temperatures, and mechanical strength is higher.
The purpose of this utility model is achieved in that a kind of waterproof feeder cable for magnetic suspension train, comprise the conductor shield being coated on cable core periphery, the periphery of conductor shield is coated with insulating barrier, the periphery of insulating barrier is vertical is surrounded by the first semiconductor waterstop, the periphery of the first semiconductor waterstop is coated with metal wire shielding layer, the periphery of metal wire shielding layer is coated with metallic tape shield, the periphery of metallic tape shield is surrounded with the second semiconductor waterstop, the periphery of the second semiconductor waterstop is extruded with polyvinyl chloride oversheath, described first semiconductor waterstop offers some mounting holes, described cable core is the many circular aluminum conductors twisted together, between described circular aluminum conductor, water blocking yarn and water-proofing powder is filled with between circular aluminum conductor and conductor shield.
As improvement of the present utility model, described conductor shield selects zinc-plated proof copper-wire braided to form.
Compared with prior art, the beneficial effects of the utility model are, this product cable core adopts circular aluminum conductor, and successively twists into water blocking yarn and water-proofing powder, circular aluminum conductor electric fields uniform, and have good can curvature and flexibility, diameter is less, and water blocking yarn embeds in the space between aluminium conductor after overcompaction continuously, and then formed successional " water blocking ", make on the continuous length of whole conductor, form continuous print conductor stop water, stop conductor longitudinally water inlet completely; Conductor shield prevents from the metal ion in conductor to be diffused into going in insulation and cause water tree and electric branch, thus affects cable life; The structure that outer screen uses copper wire copper strips to combine, to prevent induced electromotive force excessive, also ensure that screen does not produce slip when expanded by heating, and brass wire shielding infrastructure product has good bending property and stretch-proof performance simultaneously; First semiconductor waterstop offers some mounting holes, makes insulating barrier infiltrate in mounting hole extruding in process, avoid between the first semiconductor waterstop and insulating barrier and relative sliding occurs, strengthen the stability of cable work.The utility model can be used in magnetic suspension train.
Accompanying drawing explanation
