CN104867580A - Marine shielded-insulated cable with current-guiding wire - Google Patents

Abstract

The invention discloses a marine shielded-insulated cable with a current-guiding wire. The marine shielded-insulated cable is composed of aluminum conductors, a nickel belt shielding layer, an aluminum alloy belt shielding layer, a silicone rubber insulating layer and a low-smoke halogen-free polyolefin sheath layer. The aluminum conductors form seven groups of cable cores, each group of cable cores comprises three of the aluminum conductors, the seven groups of cable cores are twisted together and extruded with the nickel belt shielding layer, the nickel belt shielding layer is wrapped with the aluminum alloy belt shielding layer, the aluminum alloy belt shielding layer is wrapped with the silicone rubber insulating layer, and the silicone rubber insulating layer is wrapped with the low-smoke halogen-free polyolefin sheath layer. The marine shielded-insulated cable has the advantages of good shielding and insulating performance, good bending resistance, high conductivity, high temperature resistance, and high magnetic interference resistance.

Description

A kind of boats and ships shielding insulation band drainage thread cable

Technical field

The present invention relates to field of cables, particularly relate to a kind of boats and ships shielding insulation band drainage thread cable.

Background technology

At present, at present, along with socioeconomic development, electric wire consumption increases rapidly, also constantly improves the quality requirement of cable, such as in aviation, the cable used in the field such as electric power, boats and ships, to shielding insulation performance, the resist bending performance of cable, conductance, high temperature resistant, the requirement of diamagnetic interference aspect of performance is high all especially.If the incomplete words that cable possesses, the work in these fields and benefit can be affected.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of high temperature resistant, insulation shielding is effective, and diamagnetic interference is strong, resist bending boats and ships shielding insulation of good performance band drainage thread cable.

The present invention takes following technical scheme to realize: a kind of boats and ships shielding insulation band drainage thread cable, it is by aluminium conductor, nickel strap screen, aluminum alloy strip screen, silicone rubber insulation layer and low-smoke halogen-free polyolefin restrictive coating composition, described aluminium conductor every three one group forms one group of cable core, be seven groups altogether, one deck nickel strap screen is extruded with outside seven groups of cable cores twist together, outer wrapping one deck aluminum alloy strip screen of described nickel strap screen, outer wrapping one deck silicone rubber insulation layer of described aluminum alloy strip screen, outer wrapping one deck low-smoke halogen-free polyolefin restrictive coating of described silicone rubber insulation layer, described nickel strap screen inside is extruded with a copper wire drainage thread.

The present invention has following beneficial effect in sum: this cable has good shielding insulation performance, resist bending performance, and conductance is high, also has high temperature resistant, the feature that diamagnetic interference is strong simultaneously.
