Abstract
Disclosed in the utility model is a polyvinyl chloride sheath type control cable that comprises at least two circular metal conductors. Polyvinyl chloride insulation layers are respectively arranged outside the circular metal conductors; a wrapping layer coats the outsides of the polyvinyl chloride insulation layers; and space between the wrapping layer and the polyvinyl chloride insulation layers is filled with filling ropes, wherein the filling ropes are arranged at the central portion and the space between the adjacent polyvinyl chloride insulation layers and the wrapping layer. A shielding layer is arranged outside the wrapping layer; a fire-retardant coating layer is arranged outside the shielding layer; and a polyvinyl chloride sheath layer is arranged outside the fire-retardant coating layer. According to the utility model, the provided polyvinyl chloride sheath type control cable has the characteristics of high insulation reliability, good flame-retardant effect, prolonged cable service life, enhanced stability, and good fireproof performances and can be applied to the indoor area, the tunnel, the cable trench, or buried laying and the like.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of pvc sheath type control cable.
Background technology
Development along with power industry, data communication industry, urban track traffic industry etc., all trades and professions are more and more higher to the requirement of cable, in use, will avoid not only that cable is mechanically damaged, insulation harm, ageing of insulation are rotten etc., also under hot conditions, use, namely high temperature resistant.The current capacity of cable is relevant with the sectional area of conductor thread core usually simultaneously, conductor temperature is raise, the temperature of the outer insulating barrier that coats of conductor surpasses the last change that can cause on the insulating barrier generation performance in limited time, thereby the insulating reliability of insulating barrier is reduced greatly, influence the useful life of cable.
Existing common cable exists structural stability difference and easy firing, the problem of fire protecting performance difference, so the fire-retardant problem of the lsafety level of electric wiring and cable more and more causes people's attention; Even if cable has good heat resistance, in the higher occasion of fail safe, but can not prevent vegeto-animal destruction, also may bring big indirect loss to power supply.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of pvc sheath type control cable to be provided.
The utility model is achieved through the following technical solutions:
A kind of pvc sheath type control cable, it is characterized in that: include at least two circular metal conductors, and the circular metal conductor is respectively equipped with the polyvinyl chloride insulation layer outward, described polyvinyl chloride insulation layer is coated with lapping layer, be provided with gasket for packing between described lapping layer and the polyvinyl chloride insulation layer, described gasket for packing is filled between center and adjacent polyvinyl chloride insulation layer and the lapping layer, described lapping layer is provided with screen outward, described screen is provided with the fireproof paint layer outward, and described fireproof paint layer is provided with the pvc sheath layer outward.
The external diameter of described polyvinyl chloride insulation layer is 1.2mm～1.6mm.
Described screen adopts two-layer plastic-aluminum combined film coiling to form, the wrapped plastic-aluminum combined film of its internal layer, coverage rate 100%; The outer braid tinned wird, shielding density is more than 93%.
Described gasket for packing includes Su Lunsi and flame-retardant polyurethane elastic body, and the gasket for packing of its center is the flame-retardant polyurethane elastic body, and the gasket for packing between adjacent polyvinyl chloride insulation layer and the lapping layer is Su Lunsi.
The utility model has the advantages that:
The utility model adopts the polyvinyl chloride insulation layer, and under rated voltage 0.6/1kV condition of power supply, the insulating reliability of its polyvinyl chloride insulation layer is big; Adopt the pvc sheath layer, the good flame retardation effect of its polyvinyl chloride external sheath layer, and then prolonged useful life of cable, by gasket for packing inner core is fixed simultaneously, can prevent vegeto-animal destruction and strengthen its stability, and then prolong the useful life of cable, by the structural design of fireproof paint layer, its fire protecting performance is good, is used in indoor, tunnel, the cable trough or buried-pipe laying etc.
Description of drawings
Fig. 1 is the utility model structural representation.
