Abstract

The utility model discloses an LSOH sheath cable with drainage wires; the LSOH sheath cable comprises three sets of nickel conductor cable cores, a PTFE insulation layer, an EP rubber insulation layer, a copper belt shield layer, an aluminium belt armor layer and a LSOH polyolefin sheath layer; the three sets of nickel conductor cable cores are extruded in the PTFE insulation layer; the PTFE insulation layer is extruded by the EP rubber insulation layer wrapped by the copper belt shield layer; the copper belt shield layer is wrapped by the aluminium belt armor layer. The cable is aging resistant, LSOH flame retardation, strong in acid and alkali resistance and corrosivity resistant, excellent in insulation property, and can be widely applied in petroleum chemical, metallurgy and electric power fields.

Description

A kind of band drainage thread low-smoke halogen-free sheathed cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of band drainage thread low-smoke halogen-free sheathed cable.

Background technology

At present, be applied to the cable in the fields such as petrochemical industry, metallurgical electric power, all very high to the each side quality requirement of cable, because very important of fail safe in these fields, generally not admit of potential safety hazard to exist, in these fields, just should use so that some are ageing-resistant, low-smoke non-halogen flame-retardant, acid-alkali-corrosive-resisting is strong and have the excellent cable of insulation property, can better ensure and produce and improve fail safe.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of band drainage thread low-smoke halogen-free sheathed cable with the strong and good insulation preformance of low-smoke non-halogen flame-retardant, acid-alkali-corrosive-resisting.

The utility model takes following technical scheme to realize: a kind of band drainage thread low-smoke halogen-free sheathed cable, it is by nickel conductor cable core, teflon insulation layer, ethylene propylene rubber insulated layer, copper strip shielding layer, aluminium strip armour and low-smoke halogen-free polyolefin restrictive coating form, described nickel conductor cable core is set to three groups, all be extruded in teflon insulation layer inner, outside described teflon insulation layer, be extruded with the ethylene propylene rubber insulated layer of one deck, outside described ethylene propylene rubber insulated layer, be extruded with one deck copper strips screen, outside described copper strip shielding layer, be enclosed with one deck aluminium strip armour, described ethylene propylene rubber insulated layer inside is extruded with 16 group aluminum alloy conductor cable cores, described copper strip shielding layer inside is extruded with eight groups of zinc-plated aluminium conductor cable cores, described nickel conductor cable core inside is extruded with three nickel conductors.

Described nickel conductor cable core inside is also extruded with a copper wire drainage thread.

The utlity model has in sum following beneficial effect: this cable has ageing-resistant, low-smoke non-halogen flame-retardant, acid-alkali-corrosive-resisting is strong and have the excellent feature of insulation property, is widely used in the fields such as petrochemical industry, metallurgical electric power.
