Abstract
The invention discloses a tinned steel tape armor insulating flexible wire. The tinned steel tape armor insulating flexible wire is composed of copper conductor cable cores, aluminum conductor cable cores, nickel conductor cable cores, a butyronitrile insulating layer, a tinned steel tape armor layer, a non-magnetic metal armor layer, a polytetrafluoroethylene insulating layer and a low-smoke zero-halogen polyolefin sheath layer, wherein the copper conductor cable cores, the aluminum conductor cable cores and the nickel conductor cable cores are all wrapped in the butyronitrile insulating layer in an extrusion mode, the copper conductor cable cores are in two sets, the aluminum conductor cable cores are in three sets, the nickel conductor cable cores are in four sets, the butyronitrile insulating layer is wrapped in the tinned steel tape armor layer, and the tinned steel tape armor layer is wrapped in the non-magnetic metal armor layer. The tinned steel tape armor insulating flexible wire 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 galvanized steel strip armouring insulation cord.
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 galvanized steel strip armouring insulation cord that electric conductivity is excellent.
The present invention takes following technical scheme to realize: a kind of galvanized steel strip armouring insulation cord, it is by copper conductor cable core, aluminium conductor cable core, nickel conductor cable core, butyronitrile insulating barrier, galvanized steel strip armour, nonmagnetic metal armour, teflon insulation layer and low-smoke halogen-free polyolefin restrictive coating composition, described copper conductor cable core, aluminium conductor cable core and nickel conductor cable core are all extruded in butyronitrile insulating barrier inside, described copper conductor cable core is set to two groups, described aluminium conductor cable core is set to three groups, described nickel conductor cable core is set to four groups, outside described butyronitrile insulating barrier, wrap up one deck galvanized steel strip armour, outside described galvanized steel strip armour, wrap up one deck nonmagnetic metal armour.
Described copper conductor cable core inside is extruded with 7 copper conductors, and described aluminium conductor cable core inside is extruded with 10 aluminium conductors, and described nickel conductor cable core inside is extruded with 12 nickel conductors.
The present invention has following beneficial effect in sum: this kind of electric wire is ageing-resistant, resistance to oxidation, acid and alkali-resistance, low-smoke non-halogen flame-retardant, have cold-resistant, good insulating, soft advantage also has the excellent feature of electric conductivity simultaneously.
