Abstract
The invention relates to a novel multicore fireproof cable. The novel multicore fireproof cable comprises a conductor, wherein a fireproof layer is arranged outside the conductor, an insulating layer is arranged outside the fireproof layer, an inner sheath layer is arranged outside the insulating layer, a packing layer is arranged outside the inner sheath layer, a taped covering layer is arranged outside the packing layer, a copper wire armoured layer is arranged outside the taped covering layer, and an outer sheath layer is arranged outside the copper wire armoured layer. The novel multicore fireproof cable is good in fireproof performance, high in strength and environmentally-friendly and has no harmfulness to operating personnel.
Description
Technical field
The present invention relates to a kind of cable, be 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.Common fireproof control cable does not have very high anticollision function simultaneously.When fire occured, common fireproof control cable can't guarantee that circuit works on, and was difficult to strive for time of more growing for escape and rescue.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 objective of the invention is provides a kind of fire protecting performance good in order to overcome deficiency of the prior art, and intensity is high, environmental protection, to operating personnel without nocuous Novel multi-core fireproof cable.
Technical scheme: in order to solve the problems of the technologies described above, a kind of Novel multi-core fireproof cable of the present invention, it comprises conductor, outside described conductor, be provided with fireprotection layer, outside described fireprotection layer, be provided with insulating barrier, outside described insulating barrier, be provided with inner restrictive coating, outside described inner restrictive coating, be provided with packed layer, outside described packed layer, be provided with lapping layer, outside described lapping layer, be provided with the copper wire armored layer, outside described copper wire armored layer, be provided with external sheath layer.
Described conductor is five.
Described conductor is copper conductor or tinned copper conductor.
Described fireprotection layer is inorganic short fiber adhesive-layer, and its thickness is between 1-3mm.
Described packed layer is the composite material of silicon carbide packed layer.
Described external sheath layer is halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: fireprotection layer of the present invention adopts inorganic short fiber adhesive-layer, greatly improved the fire protecting performance of product, not only environmental protection but also safety, adopt the copper wire armored layer, greatly improved the intensity of product, packed layer adopts the composite material of silicon carbide packed layer, has greatly improved filling effect.
