Abstract

The utility model discloses a multilayer protective sleeve flexible wire for metallurgy and power generation. The multilayer protective sleeve flexible wire for the metallurgy and power generation comprises an aluminum alloy conductor, a galvanized aluminum wire shielding layer, a silicon rubber insulating layer, a polyvinyl chloride insulating layer, a low smoke halogen-free polyolefin sheath layer, a butyronitrile insulating layer, a chlorosulfonation polyethylene sheath layer and an aluminum belt armor PVC sheath layer. 27 aluminum alloy conductors are provided and extruded together, and are covered with one galvanized aluminum wire shielding layer; the galvanized aluminum wire shielding layer is covered with one silicon rubber insulating layer; the silicon rubber insulating layer is coated with one polyvinyl chloride insulating layer; and the polyvinyl chloride insulating layer is coated with one low smoke halogen-free polyolefin sheath layer. The multilayer protective sleeve flexible wire for the metallurgy and power generation is resistant to aging, resistant to oxidization, and long in service life, has the advantages of being resistant to coldness, good in insulation, great in softness, and has the characteristics of being great in anti magnetic interference.

Description

A kind of metallurgical generating is overlapped cord with multilayer proofing

Technical field

The utility model belongs to electric wire field, relates in particular to a kind of metallurgical generating multilayer proofing and overlaps 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, diamagnetic interference, tension is the durable and characteristic that conducts electricity very well firmly, just can ensure safety.

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 environmental protection, has softness, good insulation preformance, and the metallurgy generating that diamagnetic interference is good is overlapped cord with multilayer proofing.

The utility model takes following technical scheme to realize: a kind of metallurgical generating is overlapped cord with multilayer proofing, it is by aluminium alloy conductor, zinc-plated aluminium wire screen, silicone rubber insulation layer, polyvinyl chloride insulation layer, low-smoke halogen-free polyolefin restrictive coating, butyronitrile insulating barrier, chlorosulfonated polyethylene sheath layer and aluminium strip armouring pe sheath layer composition, described aluminium alloy conductor is provided with 27, outside being extruded in together, wrap up the zinc-plated aluminium wire screen of one deck, outside described zinc-plated aluminium wire screen, wrap up one deck silicone rubber insulation layer, outside described silicone rubber insulation layer, wrap up one deck polyvinyl chloride insulation layer, outside described polyvinyl chloride insulation layer, wrap up one deck low-smoke halogen-free polyolefin restrictive coating, described silicone rubber insulation layer inside is extruded with 8 groups of nickel conductor cable cores, described low-smoke halogen-free polyolefin restrictive coating inside is extruded with 16 groups of tinned copper conductor cable cores, described butyronitrile insulating barrier inside is extruded with 16 groups of tinned copper conductor cable cores.

The utlity model has in sum following beneficial effect: this kind of electric wire is ageing-resistant, resistance to oxidation, long service life, have cold-resistant, good insulating, soft advantage also has the excellent feature of diamagnetic interference simultaneously.
