Certainly, can also be before conductor passes mistake conductor bores on core rod, at outside waterstop or polyester belt or other the suitable band of coating of conductor, just can not be bonded with the restrictive coating material in conductive surface or stranded gap so yet, can construct more easily and continue like this.
Cable in the present invention only has conductor and restrictive coating, and therefore, structure is simpler, the outside diameter of cable of same specification is less, material cost is lower; Simultaneously, owing to having lacked isolation step, therefore, make convenient, make in machinery equipment drop into still less, manually/power consumption more saves; Therefore manufacturing cost is lower; In the present invention, the existence of recognition unit can in the situation that there is no insulating barrier and there is no color identification, also can identify the accurate location of conductor in cable, the existence of recognition unit not only can make conductor identify, therefore and effectively reduced cost because consumptive material reduces; The existence of light unit in the present invention makes cable not only have the function of transmission of electricity, and can reach for signal monitoring by transmitting optical signal, has enlarged widely the scope of application of cable.In the present invention, due to the special formulation of cable sheath material, make cable have better insulation, proof voltage, anti-ant, fire-retardant, fire resistance.In this cable, when adopting stranded conductor, product is soft, more easily continues and lays with construction.
Therefore, the present invention has following main beneficial effect: product structure is simpler, cost is lower, it is easier to make, make in equipment investment still less.
The present invention is not limited to above-mentioned preferred forms, should be appreciated that design of the present invention can be by other various forms enforcement utilizations, and they drop in protection scope of the present invention equally
