Abstract

The invention discloses an insulated and shielded power cable for ships. The insulated and shielded power cable is composed of four groups of conductor wire cores, six protective layers and four drainage wires, wherein the six protective layers are a tetrafluoroethylene-hexafluoropropylene copolymer insulating layer, a galvanized aluminum wire shielding layer, a chlorosulphonated polyethylene jacket layer, an ethylene propylene rubber insulating layer, a tinned copper wire shielding layer and a silver-plated steel strip polyethylene jacket layer in sequence from inside to outside; the four groups of conductor wire cores are respectively two groups of silver-plated aluminum alloy conductor wire cores and two groups of silver-plated nickel conductor wire cores; the four drainage wires all are tinned copper wire drainage wires. The cable has the characteristics of excellent magnetic interference resistance, good insulating and shielding effects and high oxidation resistance, can be widely applied to the fields such as aviation and shipping, and is light in weight.

Description

A kind of boats and ships insulation shielding power cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of boats and ships insulation shielding power cable.

Background technology

Cable and wire is the medium of transmission of electric energy, cable is widely used in every field, relate to people's lives, industrial production various aspects, the quality requirement of each field to cable differs, and some key areas are high especially to the quality requirement of cable, not so cannot satisfy the demand, and may make troubles to work, in the middle of aviation ship domain, it is excellent that cable has diamagnetic jamming performance, the feature that insulation shielding is effective, can be safer.

Summary of the invention

In order to increase the practicality of prior art, the object of this invention is to provide a kind of diamagnetic jamming performance excellent, the boats and ships insulation shielding power cable that insulation shielding is effective.

The present invention takes following technical scheme to realize: a kind of boats and ships insulation shielding power cable, it is by four groups of conductor thread cores, six layers of protective layer and four drainage thread compositions, six layers of protective layer are followed successively by perfluoroethylene-propylene insulating barrier from inside to outside, zinc-plated aluminium wire screen, chlorosulfonated polyethylene sheath layer, ethylene propylene rubber insulated layer, tinned copper wire screen and silver-plated steel band pe sheath layer, described perfluoroethylene-propylene insulating barrier is set to the central core of cable, four groups of conductor thread cores are respectively two groups of silver coated aluminum alloy conductor cores and two groups of silver-plated nickel conductor thread cores, four groups of conductor thread cores are evenly extruded in perfluoroethylene-propylene insulating barrier, between zinc-plated aluminium wire screen and chlorosulfonated polyethylene sheath layer, described silver coated aluminum alloy conductor core inside extrudes 19 silver coated aluminum alloy conductors, described silver-plated nickel conductor thread core inside extrudes ten silver-plated nickel conductors, four drainage threads are all tinned copper wire drainage thread, be extruded in chlorosulfonated polyethylene sheath layer symmetrically, between ethylene propylene rubber insulated layer and tinned copper wire screen.

The silver-plated copper strips armour of one deck is extruded outside the conductor of described silver coated aluminum alloy conductor core and silver-plated nickel conductor thread core inside.

Described silver coated aluminum alloy conductor cross-sectional diameter length is 0.25 ㎜.

Described silver-plated nickel conductors cross diameter length is 0.4 ㎜.

The present invention has following beneficial effect in sum: it is excellent that this kind of cable has diamagnetic jamming performance, and insulation shielding is effective, the feature that non-oxidizability is strong, can be widely used in the fields such as aviation boats and ships, and weight is little.
