CN203787149U - Pressure-resistant tensile electric wire for aviation - Google Patents

Abstract

The utility model discloses a pressure-resistant tensile electric wire for aviation. The electric wire is composed of control wire cores, a nickel tape shielding layer, a tinned copper tape shielding layer, a non-magnetic metal armored layer, a polytetrafluoroethylene insulation layer and an aluminum tape armored polyethylene sheath layer. The three control wire cores are extruded inside the nickel tape shielding layer. Each control wire core is composed of a polyester fiber layer used as a middle layer, an ethylene propylene rubber insulation layer coating the polyester fiber layer, and four tinned nickel conductor cable cores extruded in the ethylene propylene rubber insulation layer. The nickel tape shielding layer is coated with the tinned copper tape shielding layer. The electric wire has high bending resistance and good heat dissipation effect, is resistant to high temperature, acid and alkali, and cold, and has the advantages of strong antioxidant capacity and high compressive strength and tensile strength.

Description

A kind of withstand voltage electric wire for aviation of resistance to tension

Technical field

The utility model belongs to electric wire field, relates in particular to a kind of withstand voltage electric wire for aviation of resistance to tension.

Background technology

At present, along with Chinese society expanding economy, electric wire electric wire consumption increases rapidly, the quality requirement of electric wire is also constantly improved, such as the electric wire using in the fields such as aviation boats and ships, the high and low temperature resistance to electric wire, the resistance to pull resistance of resistance to compression, acid and alkali-resistance, cold-resistant high temperature resistant and non-oxidizability 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 a kind of high temperature resistant, cold-resistant, the withstand voltage electric wire for aviation of resistance to tension that the resistance to pull resistance of resistance to compression is strong.

The utility model takes following technical scheme to realize: a kind of withstand voltage electric wire for aviation of resistance to tension, it is by controlling core, nickel strap screen, tin-coated copper strip screen, nonmagnetic metal armour, teflon insulation layer and aluminium strip armouring pe sheath layer composition, described control core is extruded in nickel strap screen inside, be provided with three groups, described control core is by the layer of polyester fiber as intermediate layer, be wrapped in the ethylene propylene rubber insulated layer outside layer of polyester fiber and be extruded in four groups of zinc-plated nickel conductor cable core compositions within ethylene propylene rubber insulated layer, outside described nickel strap screen, wrap up one deck tin-coated copper strip screen, gap between three groups of control cores, the center of nickel strap screen is extruded with steel cable.

The utlity model has in sum following beneficial effect: this kind of electric wire resistance to bend(ing) is strong, good heat dissipation effect is high temperature resistant, and acid and alkali-resistance is cold-resistant, also has non-oxidizability strong, the advantage that the resistance to pull resistance of resistance to compression is strong simultaneously.
