Abstract
The utility model discloses an insulation fireproof multi-core power cable including a cable core made by at least six wire cables. The outer side of the cable core is sequentially provided with a package taped covering layer, an internal protective cover layer, a titanium alloy sheath steel tape armoring layer and an external protective layer. Filler material is arranged between the cable core and the package taped covering layer. The cable core comprises a conductor, a shielding layer, a mica asbestos layer and an insulating layer. According to the utility model, by arrangement of the mica asbestos layer with a mixture of white mica and serpentine asbestos outside the conductor, the fire resistance of the product is improved so that the cable can work properly at a high temperature; by arrangement of the titanium alloy sheath steel tape armoring layer, the strength of the product is improved, and the weight is also lighter than that by use of a steel tape armoring layer with stainless steel as sheath; and by arrangement of the EPDM rubber external protective cover layer, the glass fiber non-woven fabric taped covering layer and the brominated polystyrene filler rope that are mixed with a PVC fire retardant, the flame resistance of the product is further enhanced and the normal operation of the product in some special occasions can be guaranteed.
Description
Technical field
The utility model relates to the cable technology field, particularly a kind of fireproof cable.
Background technology
Along with the quickening of present various capital constructions, capital construction and development of real estate speed, inevitable as supplying, join the main line of advocating peace to become in various facilities with power cable.But while applying as large-scale supply station, subway and skyscraper in some specific occasions, the fire protecting performance of existing power cable is just slightly inadequate, and the power cable of higher fire resistance need to be provided.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of insulation fire prevention multi-core power cable is provided.
Insulation fire prevention multi-core power cable of the present utility model, comprise the cable core that at least six-cable twists into, and in the described cable core outside, wraps up successively lapping layer, internal protective cover layer, titanium alloy sheath steel-tape armouring layer and external protection; Be provided with inserts between described cable core and parcel lapping layer; Described cable core comprises conductor, screen, mica asbestos layer and insulating barrier, is enclosed with successively screen, mica asbestos layer and insulating barrier on conductor.
Described conductor is gold plated copper conductor or gold-plated silver conductor.
Described screen is lead plating proof copper-wire braided screen.
Described insulating barrier is low-smoke non-halogen flame-retardant cross-linked polyolefin insulating barrier.
Described inserts is the brominated Polystyrene gasket for packing.
Described parcel lapping layer is the glass fibre non-woven lapping layer.
Described internal protective cover layer is the expanded polystyrene (EPS) protective sleeve.
In sum, insulation fire prevention multi-core power cable provided by the utility model is outside equipped with the mica asbestos layer at conductor, has improved the fire resistance of product, and cable can normally move when high temperature; Be provided with the intensity that titanium alloy sheath steel-tape armouring layer has improved product, the firm band armour as sheath than rustless steel, also alleviated weight simultaneously; Outer jointing jacket layer, glass fibre non-woven lapping layer and brominated Polystyrene gasket for packing are set, have further improved the anti-flammability of product, can guarantee the normal operation of product at some special occasions.
