Abstract
The invention discloses a butyronitrile insulating low-smoke zero-halogen power cable. The butyronitrile insulating low-smoke zero-halogen power cable is composed of an aluminum conductor cable core, a tinned aluminum conductor cable core, a copper conductor cable core, an aluminum tape armor layer, a butyronitrile insulating layer, a tinned aluminum wire shielding layer, a polytetrafluoroethylene insulating layer and a low-smoke zero-halogen polyolefin sheath layer, wherein the aluminum conductor cable core, the tinned aluminum conductor cable core and the copper conductor cable core are wrapped inside the aluminum tape armor layer in an extrusion mode, the aluminum conductor cable core, the tinned aluminum conductor cable core and the copper conductor cable core are respectively in a set, the aluminum tape armor layer is wrapped in the butyronitrile insulating layer, and the butyronitrile insulating layer is wrapped in the tinned aluminum wire shielding layer. The butyronitrile insulating low-smoke zero-halogen power cable is resistant to aging, oxidation, acid and alkali, low in smoke, free of halogen, and fire-retardant, and has the advantages of being resistant to cold, good in insulation performance, soft and good in electric conductivity.
Description
Technical field
The invention belongs to electric wire field, relate in particular to a kind of butyronitrile insulating low-smoke halogen-free power cable.
Background technology
Electric wire refers to the wire of conduction current, be widely used in petrochemical industry, metallurgical generating, square, tunnel every field, these fields require all high to the indices of electric wire, such as requiring to there is resistance to oxidation, cold-resistant, insulation, soft, low-smoke non-halogen flame-retardant, acid and alkali-resistance and the characteristic conducting electricity very well, just can ensure safety.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of softness, good insulation preformance, acid and alkali-resistance, the butyronitrile insulating low-smoke halogen-free power cable that electric conductivity is excellent.
The present invention takes following technical scheme to realize: a kind of butyronitrile insulating low-smoke halogen-free power cable, it is by aluminium conductor cable core, zinc-plated aluminium conductor cable core, copper conductor cable core, aluminium strip armour, butyronitrile insulating barrier, zinc-plated aluminium wire screen, teflon insulation layer and low-smoke halogen-free polyolefin restrictive coating composition, described aluminium conductor cable core, zinc-plated aluminium conductor cable core and copper conductor cable core are all extruded in aluminium strip armour inside, described aluminium conductor cable core, described zinc-plated aluminium conductor cable core and described copper conductor cable core are set to respectively one group, outside described aluminium strip armour, wrap up one deck butyronitrile insulating barrier, outside described butyronitrile insulating barrier, wrap up the zinc-plated aluminium wire screen of one deck.
Described aluminium conductor cable core inside is extruded with 10 aluminium conductors, and described zinc-plated aluminium conductor cable core inside is extruded with 12 zinc-plated aluminium conductors, and described copper conductor cable core inside is extruded with 7 copper conductors.
