Abstract

The utility model discloses a light insulation communication cable with a thin wall for a navy ship. Cross-linked polyethylene insulation layers are coated outside a plurality of inner conductors in a pressing manner to form an insulation core; two insulation cores are hinged and equipped with metal wire intertexture shielding layers to form a basic wire pair; a plurality of basic wire pairs are stranded to form a cable core; the core is wound by a halogen-free coating layer to form a winding layer; an inner protective layer is coated with the winding layer; an inner protective layer is arranged outside the metal wire intertexture shielding layers; and an outer protective layer is wound outside the cable. The cable disclosed by the utility model meets the requirement on high density wiring in a narrow space of the navy ship, and ensures high-speed, safe, stable and high reliable signal transmission between electronic devices in the navy ship.

Description

Marine light thinwalled insulation telecommunication cable

Technical field:

The utility model relates to a kind of marine light thinwalled insulation telecommunication cable, belongs to technical field of electric wires and cables.

Background technology:

Present domestic naval vessel shows mainly that with telecommunication cable the outside diameter of cable is big and heavy; Though this type cable has good mechanical performance and electric property; But can not adapt to the Modern Ships demand for development; Along with the development of modern science and technology to information-based, high speed and safe, the high-density wiring of the confined space in the naval vessel has been proposed more strict requirement, it is little, in light weight but also have mechanical performance and the electric property of excellence, characteristics easy for installation to require cable not only to have an external diameter.

Summary of the invention:

For overcoming the defective of prior art; The purpose of the utility model is to provide a kind of marine light thinwalled insulation telecommunication cable; To satisfy the narrow space high-density wiring requirement in the naval vessel, ensure high speed, safety, stable, the highly-reliable transmission of signal between the marine electronic equipment.

The utility model technical solution problem adopts following technical scheme:

Marine light thinwalled insulation telecommunication cable is extruded with crosslinked polyetylene insulated layer and constitutes insulated wire cores outside the multiply inner wire, two said insulated wire cores pair twists also are provided with the metal wire knitted sub-shield at skin to form a fundamental line right;

Constitute cable conductor by many said fundamental line strands; Cable core is outer with the wrapped formation lapping layer of Halogen band; Outside said lapping layer, be extruded with inner restrictive coating, be outside equipped with the metal wire knitted armour at said inner restrictive coating, the outermost layer of cable is extruded with external sheath layer.

Said inner wire is to close formation with zinc-plated soft copper skein silk.

Said inner restrictive coating, external sheath layer are extruded by cross-linked polyolefin and form.

Compared with present technology, the beneficial effect of the utility model is embodied in:

1, the utility model cable insulation adopts crosslinked polyethylene, and insulation thickness is ultra-thin, is merely 0.20～0.35mm, through adopting the crosslinking process method to improve electric property, mechanical performance and the environmental adaptability of insulating barrier.

2, the utility model outside diameter of cable is little, reduces 20% at least than original outside diameter of cable.

3, the utility model cable is in light weight, alleviates 16% at least than original cable weight.

4, the utility model cable is because external diameter is little, in light weight, and it is very convenient to install.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Label among the figure: 1 inner wire, 2 insulating barriers, 3 sub-shields, 4 lapping layers, 5 inner restrictive coatings, 6 armours, 7 external sheath layers.

Below pass through embodiment, and combine accompanying drawing that the utility model is described further.

Embodiment:

Embodiment: referring to Fig. 1; The marine light thinwalled insulation telecommunication cable of present embodiment; Outside multiply inner wire 1, be extruded with crosslinked polyetylene insulated layer 2 and constitute insulated wire cores, two said insulated wire cores pair twists also are provided with metal wire knitted sub-shield 3 at skin to form a fundamental line right;

Constitute cable conductor by many said fundamental line strands; Cable core is outer with the wrapped formation lapping layer 4 of Halogen band; Outside said lapping layer 4, be extruded with inner restrictive coating 5, be outside equipped with metal wire knitted armour 6 at said inner restrictive coating 5, the outermost layer of cable is extruded with external sheath layer 7.

In the practical implementation; Multiply inner wire 1 is to close with zinc-plated soft copper skein silk; Insulating barrier 2 is to be material with the cross-linking polyethylene materials, and said sub-shield 3 is with zinc-plated soft copper silk braiding with armour 6, and described inner restrictive coating 5 and external sheath layer 7 are to be material with the cross-linked polyolefin material.
