Abstract

The invention discloses a pressure-resistant ship wire. The pressure-resistant ship wire is composed of control wire cores, a silicone rubber insulating layer, a tinned copper tape shielding layer, a polyvinyl chloride sheath layer, a polytetrafluoroethylene insulating layer and an aluminum armor polyethylene sheath layer, wherein the control wire cores are extruded inside the silicone rubber insulating layer, the number of the control wire cores is three, each control wire core is composed of a polyester fiber layer as a middle layer, an ethylene-propylene rubber insulating layer wrapped outside the polyester fiber layer and four tinned nickel conductor cable cores extruded inside the ethylene-propylene rubber insulating layer, and the silicone rubber insulating layer is wrapped in the tinned copper tape shielding layer. The pressure-resistant ship wire is good in bending resistance, good in heat radiation effect and resistant to high temperature, acid, alkali and low temperature, and further has the advantages of being high in oxidation resistance and pressure resistance.

Description

A kind of withstand voltage ship wire

Technical field

The invention belongs to electric wire field, relate in particular to a kind of withstand voltage ship wire.

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, high and low temperature resistance to electric wire, crushing resistance, acid and alkali-resistance, cold-resistant high temperature resistant and non-oxidizability aspect require all high especially.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one high temperature resistant, cold-resistant, the withstand voltage ship wire that crushing resistance is strong.

The present invention takes following technical scheme to realize: a kind of withstand voltage ship wire, it is by controlling core, silicone rubber insulation layer, tin-coated copper strip screen, pvc sheath layer, teflon insulation layer and aluminium strip armouring pe sheath layer composition, described control core is extruded in silicone rubber insulation layer 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 silicone rubber insulation layer, wrap up one deck tin-coated copper strip screen, outside described tin-coated copper strip screen, wrap up one deck pvc sheath layer.

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