Description
Technical field
The utility model belongs to the cable technology field, is specifically related to the crosslinked polyetylene insulated armouring zero-halogen low-smoke flame-retardant electrical cable of a kind of multicore.
Background technology
Cross-linked polyethylene insulated cable has significantly improved the performance of polyvinyl chloride cable.The long-term permission working temperature of cross-linked polyethylene insulated cable can reach 90 ℃.Under 130 ℃ of temperature to keep elastic stage.The cross-linked polyethylene insulated cable weight/power ratio is light, and diameter is little, installs and lays conveniently, and attachment tab is simple, and is used widely.But power cable with cross-linked polyethylene insulation is etched or is subjected to mechanical damage in use easily, is baited by mouse or by the moth erosion of worm ant, thereby influences its electric power transfer; And most of electric wire can produce a large amount of hypertoxic dense smoke when burning, cause great life and property loss, and bring very big difficulty to rescue work, particularly at the environment of space relative closure, when using in the environment such as indoor, tunnel, can bring hidden danger to Environmental security.Therefore need improve its structure, to increase its tensile strength, compression strength, increase the service life, low smoke and zero halogen during burning further enlarges its scope of application.
The utility model content
The purpose of this utility model is to provide a kind of multicore crosslinked polyetylene insulated armouring zero-halogen low-smoke flame-retardant electrical cable.
The purpose of this utility model can be achieved through the following technical solutions:
The crosslinked polyetylene insulated armouring zero-halogen low-smoke flame-retardant electrical cable of a kind of multicore, it comprises many group cores, band, inner sheath, armouring and oversheath, described core comprises many conductors and is wrapped in the outer interior semi-conductive screen of many described conductors, insulating barrier, semi-conductive shield outside and copper strips shielding successively, described core and packing material stranded back together form cable core, the outer wrapped band of described cable core, described band is provided with inner sheath, armouring and oversheath outward successively.
The crosslinked polyetylene insulated armouring zero-halogen low-smoke flame-retardant electrical cable of above-mentioned multicore, its described armouring is steel-tape armouring or LWA light wire armoured.
The crosslinked polyetylene insulated armouring zero-halogen low-smoke flame-retardant electrical cable of above-mentioned multicore, its described conductor is copper.
The crosslinked polyetylene insulated armouring zero-halogen low-smoke flame-retardant electrical cable of above-mentioned multicore, the material of its described insulating barrier is crosslinked polyethylene.
The crosslinked polyetylene insulated armouring zero-halogen low-smoke flame-retardant electrical cable of above-mentioned multicore, the material of its described inner sheath and oversheath is low-smoke halogen-free polyolefin.
The beneficial effects of the utility model:
For preventing that power cable with cross-linked polyethylene insulation is subjected to mechanical damage, forms crosslinked polyetylene insulated armoured power cable and install steel first protective layer additional at skin.Can increase the mechanical strength of cable; improve anti-erosiveness; it is convenient to lay; can also strengthen mechanical protections such as tensile strength, compression strength and increase the service life, this armoured power cable has certain external force resistance performance, can also watch out for mouse to bait; be unlikely to see through armouring and cause the electric power transfer problem; it is big that the bending radius of armouring is wanted, and armour can ground connection, the protection cable.And this power cable does not discharge Halogen gas under the situation of burning, smokescope is low, and gas attack is low.The usage safety performance height, mechanical performance excellence, chemical-resistance are strong.
