Abstract

The invention discloses a marine shielded-armored cable with a current-guiding wire. The marine shielded-armored cable is composed of aluminum conductors, a nickel belt shielding layer, an aluminum alloy belt armored layer, a copper belt armored 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 armored layer, the aluminum alloy belt armored layer is wrapped with the copper belt armored layer, and the copper belt armored layer is wrapped with the low-smoke halogen-free polyolefin sheath layer. The marine shielded-armored cable with the current-guiding wire 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 shield band drainage thread cable

Technical field

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

The present invention takes following technical scheme to realize: a kind of boats and ships shield band drainage thread cable, it is by copper conductor, nickel strap screen, aluminum alloy strip armour, copper strips armour and low-smoke halogen-free polyolefin restrictive coating composition, described copper 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 armour of described nickel strap screen, outer wrapping one deck copper strips armour of described aluminum alloy strip armour, outer wrapping one deck low-smoke halogen-free polyolefin restrictive coating of described copper strips armour, described nickel strap screen inside is extruded with an aluminium 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.

Accompanying drawing explanation

Fig. 1 is cross-sectional structure schematic diagram of the present invention;

Wherein: 1, copper conductor; 2, nickel strap screen; 3, aluminum alloy strip armour; 4, copper strips armour; 5, low-smoke halogen-free polyolefin restrictive coating; 6, aluminium wire drainage thread.

Embodiment

As shown in Figure 1, a kind of boats and ships shield band drainage thread cable, it is by copper conductor 1, nickel strap screen 2, aluminum alloy strip armour 3, copper strips armour 4 and low-smoke halogen-free polyolefin restrictive coating 5 form, described copper conductor 1 every three one group forms one group of cable core, be seven groups altogether, one deck nickel strap screen 2 is extruded with outside seven groups of cable cores twist together, outer wrapping one deck aluminum alloy strip armour 3 of described nickel strap screen 2, outer wrapping one deck copper strips armour 4 of described aluminum alloy strip armour 3, outer wrapping one deck low-smoke halogen-free polyolefin restrictive coating 5 of described copper strips armour 4, described nickel strap screen 2 inside is extruded with an aluminium wire drainage thread 6.

The above is the embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
