Abstract

The utility model discloses a poly perfluorinated ethylene propylene insulating control cable. The poly perfluorinated ethylene propylene insulating control cable is composed of an aluminum alloy cable core, copper cable cores, a filling layer, an aluminum belt shielding layer, a tin-coated copper wire shielding layer, a belting layer, a poly perfluorinated ethylene propylene insulating layer and a low-smoke halogen-free polyolefin sheath layer. A group of the aluminum alloy cable core and six groups of the copper cable cores are extruded in the filling layer, the six groups of the copper cable cores are extruded around the aluminum alloy cable core, the aluminum belt shielding layer is wrapped outside the filling layer, the tin-coated copper wire shielding layer is wrapped outside the aluminum belt shielding layer, the belting layer is wrapped outside the tin-coated copper wire shielding layer, and the poly perfluorinated ethylene propylene insulating layer is wrapped outside the belting layer. The cable exhibits a wide range in application and the long service life, can undergo cyclic bending up to 4 million times and has the advantages of being low in smoke, free of halogen and resistant to flame; and the cable also has the advantages of high-temperature resistance, heat resistance, oxidation resistance, oil resistance and excellent performance of chemical resistance.

Description

A kind of perfluoroethylene-propylene insulation control cables

Technical field

The utility model relates to field of cables, relates in particular to a kind of perfluoroethylene-propylene insulation control cables.

Background technology

At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in aviation, boats and ships, field of petrochemical industry, low-smoke non-halogen flame-retardant to cable, cold resistance, oil resistant and chemical-resistance aspect require all high especially.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide the perfluoroethylene-propylene insulation control cables that a kind of low-smoke non-halogen flame-retardant, oil resistant and chemical-resistance aspect are good.

The utility model takes following technical scheme to realize: a kind of perfluoroethylene-propylene insulation control cables, it is by aluminium alloy cable core, copper cable core, packed layer, aluminium strip screen, tinned copper wire screen, belting layer, perfluoroethylene-propylene insulating barrier and low-smoke halogen-free polyolefin restrictive coating form, described packed layer inside is extruded with a group aluminum alloy cable core and six groups of copper cable cores, six groups of copper cable cores are around being extruded in aluminium alloy cable core around, outside described packed layer, be enclosed with one deck aluminium strip screen, outside described aluminium strip screen, be enclosed with one deck tinned copper wire screen, outside described tinned copper wire screen, be enclosed with one deck belting layer, outside described belting layer, be enclosed with one deck perfluoroethylene-propylene insulating barrier.

Described aluminium alloy cable core is comprised of aluminium alloy conductor and the copper strips armour and the zinc-plated brass wires braided armored restrictive coating that are wrapped in outside aluminium alloy conductor.

Described copper cable core is comprised of copper conductor and the silicone rubber insulation layer, copper strips armour and the zinc-plated brass wires braided armored restrictive coating that are wrapped in outside copper conductor.

The utlity model has in sum following beneficial effect: the utility model is of many uses, long service life, can experience reversed bending and reach 4,000,000 times, has the feature of low-smoke non-halogen flame-retardant, also there is high temperature resistant, heat-resisting, resistance to oxidation, oil resistant and the good advantage of chemical-resistance.
