Abstract
The utility model relates to a single-core flame resistant cable, which comprises a conductor; a flame resistant layer is arranged outside the conductor; an insulating layer is arranged outside the flame resistant layer, and the thickness of the insulating layer is between 0.5mm and 3mm; a wrapping layer is arranged outside the insulating layer; and an outer sheath layer is arranged outside the wrapping layer. The cable provided by the utility model has good flame-proof performance, good insulating and flame resistant effects, not only environmental friendly not also safe, and can reduce the labor intensity of operators.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of fireproof cable.
Background technology
Along with the fast development of national economy, as the aortal electric wire of national economy, its consumption and the scope of application are increasing.In recent years, the industries such as power plant, transformer station, smelting and petrochemical industry, very big to the demand of cable.
The sheath material of present common flame retardant cable generally adopts polyvinyl chloride or crosslinked polyethylene.This cable is owing to its design feature, and refractory temperature is low, and fire-resistant reliability is not strong.The flame-retardant layer of general cable all is to adopt glass fiber to fill, glass fiber is filled to cable direct labor and site operation personnel and is brought very large trouble, the workshop workman is flown upward in the full workshop of glass fiber when doing glass fiber filling stranding, get on the skin not only pain but also itch and can not take out, workman's occupational health will be had a strong impact on, and not environmental protection, glass fiber is filled the fire retardancy that has only satisfied cable, and is more harm than good.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of fire protecting performance good, and flame-resistant insulation is effective, and not only environmental protection but also safety reduce single core fire-resisting cable of labor intensity of operating staff.
Technical scheme: in order to solve the problems of the technologies described above, a kind of single core fire-resisting cable described in the utility model, it comprises conductor, outside described conductor, be provided with flame retardant coating, outside described flame retardant coating, be provided with insulating barrier, the thickness of this insulating barrier is provided with lapping layer outside described insulating barrier between 0.5-3mm, be provided with external sheath layer outside described lapping layer.
Described conductor is copper conductor or tinned copper conductor.
Described flame retardant coating is inorganic short fiber adhesive-layer.
Described insulating barrier is black crosslinkable polyethylene layer or weatherability black PVC layer.
Described lapping layer is the polyester belt lapping layer.
Described external sheath layer is halogen-free and low-smoke flame-retardant polyolefin sheathed layer, and its thickness is between 1.5-2.5mm.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model fireprotection layer adopts inorganic short fiber adhesive-layer, greatly improved the fire protecting performance of product, not only environmental protection but also safety, insulating barrier adopts black crosslinkable polyethylene layer or weatherability black PVC layer, insulation effect is good, and external sheath layer adopts halogen-free and low-smoke flame-retardant polyolefin sheathed layer, has greatly improved flame retardant effect.
