Abstract

The utility model discloses a polyvinyl chloride insulation flat cable composed of copper conductors, aluminum strip armor layers, silicone rubber insulating layers, a copper strip shielding layer, a non-magnetic metal armor layer, a polyvinyl chloride insulating layer and a low smoke zero halogen polyolefin sheath layer. There groups of copper cable cores are wrapped with the copper strip shielding layer in an extruding manner, each copper cable core is formed by stranding the 19 copper conductors and then wrapping an aluminum strip armor layer and a silicone rubber insulating layer, the copper strip shielding layer is wrapped with the non-magnetic metal armor layer, the non-magnetic metal armor layer is wrapped with the polyvinyl chloride insulating layer, and the polyvinyl chloride insulating layer is wrapped with the low smoke zero halogen polyolefin sheath layer. The polyvinyl chloride insulation flat cable is excellent in shielding and insulating properties, weatherability, abrasive resistance and acid and alkali resistance, and is applicable to the fields such as aviation, power generation, metallurgy and chemical industry and the like; and the polyvinyl chloride insulation flat cable is also advantaged by high power transmission capability and high-temperature resistance, and maximum service temperature is 200 DEG C.

Description

A kind of polyvinyl chloride insulation flat cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of polyvinyl chloride insulation flat cable.

Background technology

At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the fields such as aviation, generating, metallurgy, chemical industry, the shielding insulation performance to cable, the requirement of weatherability, resistance to wear and acid-proof alkaline aspect is all high especially, only meet the requirements, could improve in these fields the fail safe while manufacturing.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide the polyvinyl chloride insulation flat cable that a kind of weatherability, resistance to wear and acid-proof alkaline are good.

The utility model takes following technical scheme to realize: a kind of polyvinyl chloride insulation flat cable, it is by copper conductor, aluminium strip armour, silicone rubber insulation layer, copper strip shielding layer, nonmagnetic metal armour, polyvinyl chloride insulation layer and low-smoke halogen-free polyolefin restrictive coating form, in described copper strip shielding layer, be extruded with three groups of copper cable cores, copper cable core is outside 19 described copper conductors twist together, to wrap up one deck aluminium strip armour and one deck silicone rubber insulation layer formation, outside described copper strip shielding layer, be enclosed with one deck nonmagnetic metal armour, outside described nonmagnetic metal armour, be enclosed with one deck polyvinyl chloride insulation layer, outside described polyvinyl chloride insulation layer, be enclosed with one deck low-smoke halogen-free polyolefin restrictive coating.

Described nonmagnetic metal armour, polyvinyl chloride insulation layer and low-smoke halogen-free polyolefin restrictive coating inside are all provided with two copper conductor ground connection filaments.

The utlity model has in sum following beneficial effect: the utlity model has good shielding insulation performance, weatherability, resistance to wear and resistance to acids and bases, be applicable to applying to the fields such as aviation, generating, metallurgy, chemical industry, also there is power transmission capacity high, resistant to elevated temperatures advantage, maximum operation (service) temperature is 200 ℃.
