Abstract
The flame-retardant power cable with cross-linked polyethylene insulation LSOH (low smoke zero halogen) polyolefin sheath is characterized in that a conductor (1), a cross-linked polyethylene insulation layer (2), a zero-halogen wrapping tape (3), an LSOH polyolefin sheath (4) and an inner liner (5) are manly included, wherein the conductor (1) is covered by the cross-linked polyethylene insulation layer (2), the cross-linked polyethylene insulation layer (2) is covered by a zero-halogen wrapping tape (3), the zero-halogen wrapping tape (3) is covered by the inner liner (5), and the inner liner (5) is covered by the LSOH polyolefin sheath (4). The flame-retardant power cable with cross-linked polyethylene insulation LSOH polyolefin sheath is applied in PTD (power transmission and distribution) lines which have high flame-retardant requirements, generate less smoke when the cables catch fire, and have poor gas corrosion performance, and can bear external mechanical forces. The flame-retardant power cable is made of environment-friendly material such as the zero-halogen wrapping tape, LSOH polyolefin and the like, so that the pollution is reduced.
Description
Technical field
The utility model relates to the power cable technical field, especially a kind of crosslinked polyetylene insulated low-smoke halogen-free polyolefin sheath flame-proof power cable.
Background technology
Power cable is the cable that is used to transmit and distribute electric energy.Be usually used in the underground electrical network in city, power station lead line, industrial and mining enterprises in-line power and cross river, the submarine transmission line in sea excessively.In power circuit, the shared proportion of cable increases just gradually.
Yet common polythene insulation polythene jacket cable has combustibility, be difficult to satisfy do fire-retardant requirement, and cable discharges a large amount of dense smokes when catching fire, and gas has stronger corrosivity, can produce comparatively serious environmental and pollute.
Summary of the invention
The purpose of this utility model is to provide a kind of crosslinked polyetylene insulated low-smoke halogen-free polyolefin sheath flame-proof power cable, and this cable not only has fire resistance, and satisfies environmental requirement.
The technical solution of the utility model is:
A kind of crosslinked polyetylene insulated low-smoke halogen-free polyolefin sheath flame-proof power cable, it mainly is made up of conductor, crosslinked polyetylene insulated layer, Halogen twining package tape, low-smoke halogen-free polyolefin sheath and inner covering, described conductor is provided with crosslinked polyetylene insulated layer outward, crosslinked polyetylene insulated layer peripheral hardware has the Halogen twining package tape, the Halogen twining package tape is provided with inner covering outward, and the inner covering outside is the low-smoke halogen-free polyolefin sheath.
Circular, the fan-shaped or spindle of being shaped as of described conductor.
The material of described conductor is copper or aluminium.
Be provided with the steel-tape armouring layer between described low-smoke halogen-free polyolefin sheath and the inner covering.
The beneficial effects of the utility model are:
Crosslinked polyetylene insulated low-smoke halogen-free polyolefin sheath flame-proof power cable of the present utility model can finely satisfy the electric power transfer demand of 0.6/1kV, and the long-term maximum amount fixed temperature of conductor can reach 90 ℃.
Crosslinked polyetylene insulated low-smoke halogen-free polyolefin sheath flame-proof power cable of the present utility model be used to have high flame retardant to require and the cable cigarette that cable discharges when catching fire less, the gas attack performance is lower, can bear in the electric line of mechanical external force.The utility model adopts environment-friendly materials such as Halogen twining package tape and low-smoke halogen-free polyolefin, reduces and pollutes.Except that the general characteristic that keeps common cable and satisfy outside the GB12706.1-2002, also have following characteristics: excellent flame retardancy energy, low-corrosiveness, smog are few, satisfy the requirement of GB/T19666-2005 and Q/320282PCP006-2005 fully.
