Abstract

The utility model discloses an ocean engineering-used communication cable. A cable core is composed of six insulated wire cores, six communication wire cores and one middle wire core. Three conductor cores are sequentially wrapped with a polyester tape wrapping layer and a copper wire-braided shielding layer to form each insulated wire core; the six communication wire cores are arranged among adjacent insulated wire cores; a copper wire shielding layer is braided outside the conductor core to form each communication wire core; the middle wire core is arranged in the middle of the cable core, and two conductor cores are sequentially wrapped with the polyester tape wrapping layer and the copper wire-braided shielding layer to form the middle wire core; a polyethylene insulated layer is extruded outside a conductor to form the conductor core; and a polyester tape wrapping layer II, an inner sheath layer, a metal braided armored layer and an outer sheath layer are sequentially arranged outside the cable core. The ocean engineering-used communication cable is environmental friendly, halogen-free, low-smoke, non-poisonous and does no harm to the human body.

Description

A kind of ocean engineering telecommunication cable

technical field

The utility model relates to a kind of ocean engineering telecommunication cable, belongs to technical field of electric wires and cables.

background technology

Follow global economy to make the transition to service economy, since ' 12 ' beginning, China's marine economic industry heats up rapidly, and Chinese Sea economy is just entering the developing stage of quick health.At present, China has classified marine economy as new economic hot spot, to develop Modern Traffic transport service as important goal, using the Chinese shipbuilding industry of running business big and strong, realize boats and ships and marine engineering equipment industry development as adamantine policy, future 5 years will be assaulting fortified position period of accelerating to adjust water transport structure, promote maritime industry scientific development, accelerate transformation of the mode of economic development.

As with the supporting cable of marine engineering equipment, be also faced with rare opportunity to develop.The materials such as filling and band all due to cable may contain asbestos.Research shows, the disease relevant to asbestos is ubiquitous in multiple industrial occupation.As asbestos exploitation, processing and use asbestos or containing (building, ship and motor vehicle repair, metallurgy, weaving, machinery and power engineering, chemistry, agricultural etc.) in all trades and professions of asbestos material.EPA limits use to some asbestos friction materials, as the relevant regulations of spraying containing the fireproof coating of asbestos fibre of forbidding of promulgation in 1972.Asbestos itself nonhazardous, its maximum harm comes from its fiber, this is that one is very tiny, naked eyes are invisible fiber almost, when these tiny fibers are inhaled in human body, will adhere to and be deposited on lung, cause PUD D, asbestos have been carcinogenic substance by IARC certainly.

utility model content

The utility model provides a kind of environmental protection, low smoke, zero halogen, nontoxic, the ocean engineering telecommunication cable to human body without adverse effect.

Scheme of the present utility model is as follows: a kind of ocean engineering telecommunication cable, and cable core is made up of six roots of sensation insulated wire cores, six roots of sensation communication core, a middle core; Described insulated wire cores is led core wrapped polyester belt belting layer successively outward by three, and braiding shielding layer of copper wires forms; Described six roots of sensation communication core is arranged between adjacent insulated wire cores, and communication core weaves shielding layer of copper wires outward and forms by leading core; Described middle core is arranged in the middle of cable core, leads core wrapped polyester belt belting layer successively outward by two, and braiding shielding layer of copper wires forms; The described core of leading extrudes polyethylene layer outward by conductor and forms; Described cable core also sets gradually polyester belt belting layer II, inner restrictive coating, metal knitted armour layer and external sheath layer outward.

Further, described inner restrictive coating and external sheath layer all adopt the low cigarette polyolefin jacket of irradiation crosslinking halogen-free to extrude moulding.

Further, in described cable core, fill low smoke, zero halogen polyolefine material bar and form packed layer.

Oversheath all adopts the low cigarette polyolefin jacket of irradiation crosslinking halogen-free in the utility model cable, because the low cigarette polyolefin jacket of irradiation crosslinking halogen-free has Halogen, low cigarette, the characteristic such as nontoxic, fire-retardant, is environment-friendly type cleaning cable.The utility model adopts shielding pattern, has improved greatly the shielding properties of cable, has good anti-external electromagnetic field and disturbs and do not produce external interference.The packing that He Bianxi space, the utility model cable center space adopts low smoke, zero halogen polyolefin material to extrude, Stability Analysis of Structures, material has Halogen, low cigarette, the characteristic such as nontoxic, fire-retardant, containing asbestos, to human body without adverse effect.

brief description of the drawings

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

embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

A kind of ocean engineering telecommunication cable, cable core is made up of six roots of sensation insulated wire cores, six roots of sensation communication core 5, a centre core 6; Described insulated wire cores is led core wrapped polyester belt belting layer 3 successively outward by three, and braiding shielding layer of copper wires 4 forms; Described six roots of sensation communication core is arranged between adjacent insulated wire cores, and communication core weaves shielding layer of copper wires outward and forms by leading core; Described middle core is arranged in the middle of cable core, leads core wrapped polyester belt belting layer successively outward by two, and braiding shielding layer of copper wires forms; The described core of leading forms by extruding polyethylene layer 2 outside conductor 1; Described cable core also sets gradually polyester belt belting layer II 7, inner restrictive coating 8, metal knitted armour layer 9 and external sheath layer 10 outward.

Described inner restrictive coating 8 and external sheath layer 10 all adopt the low cigarette polyolefin jacket of irradiation crosslinking halogen-free to extrude moulding; In described cable core, fill low smoke, zero halogen polyolefine material bar and form packed layer 11.

All material in the utility model is all environment-friendly materials,, containing asbestos, human body is not produced to adverse effect.Cable has Halogen, low cigarette, the characteristic such as nontoxic, fire-retardant, is environment-friendly type cleaning cable.

Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
