Abstract

The utility model provides an one shot forming's three -core aerial [insulated] cable, including cable core, conductor, insulating layer, body, linkage segment, its characterized in that: the body comprises three cable cores, is provided with the linkage segment between two adjacent cable cores, and the cable core is inside to be provided with the conductor, and the conductor outside is provided with the insulating layer, this production simple process, and the preparation is convenient, and the mode of using plastic extrusion replaces stranding all later technologies, the great production technology that has shortened, reduction in production cost practices thrift a large amount of raw and other materials, effectual control cable's weight.

Description

One-time formed three core aerial cables

Technical field

The present invention relates to the essential electronic element that electricity, metal wire or metal tape make, the most one-time formed three core framves Empty cable.

Background technology

Along with the development of World Economics with science and technology, the demand of electric wire is increasing, and is improving, its performance requirement newly Economic situation and technical conditions under, whole world wires and cables industry development presents new trend, and environment-friendly cable progressively becomes the whole world The development priority of cable, in view of normal cable has the most serious contaminative, during manufacture, use, offal treatment There will be the public hazards materials such as substantial amounts of dioxin, lead, cadmium, halogenide, developed country is used for fewer and feweri, especially in European Union After having formulated ROHS instruction, Europe, the United States, Deng state are more and more higher to the environmental requirement of used cable, and they have forbidden use Or the non-environment-friendly cable of import, research and development and the extensive employing of ecological, environmental protective cable become international mainstream, and environment-friendly cable refers to Do not contain the heavy metal such as lead, cadmium, sexivalent chromium, hydrargyrum, do not contain bromide fire retardant, generally acknowledge that testing agency is to environmental-protecting performance through SGS Test, meets European Council Regulation (RoSH) and higher than its index request, does not produce harmful halogen gas, do not produce corrosivity Gas, during burning, fever amount is few, not the electric wire of contaminated soil.

The environment-friendly cable of prior art generally uses, copper, the drawing of aluminium monofilament, monofilament annealing, strand system, insulating exruded, one-tenth Cable is stranded, sheath, dress armour, outer jacket, such cable complex manufacturing technology, and processing cost is high, cable quality weight.

Summary of the invention

The invention provides one-time formed three core aerial cables for the problems referred to above, this product processes is simple, system Facilitate, use the mode of plastic extrusion to replace all techniques that stranding is later, greatly shorten production technology, reduce and produce Cost, saves substantial amounts of raw material, the effective weight controlling cable.

For solving the problems referred to above, the invention provides one-time formed three core aerial cables, including cable core, conductor, absolutely Edge layer, body, linkage section, it is characterised in that: body is made up of three of the cables core, the company of being provided with between two adjacent cables core The section of connecing, cable core is internally provided with conductor, is provided with insulating barrier outside conductor.

As a further improvement on the present invention, the three of the cables core center of circle is equilateral triangle or straight line.

As a further improvement on the present invention, described insulating barrier is the cross-linked polyolefin of 1 to 3 millimeters thick.

As a further improvement on the present invention, described insulating barrier outer surface is provided with nitrile rubber layer.

Operation principle:

The product of the present invention is provided with rational layout designs, can effectively reduce the processing technique of three-core cable, pass through Disposable expressing technique is with regard to stranding, and the effective technological process of production shortening cable, by direct expressing technique at conductor Upper composite insulation layer and linkage section, have production efficiency high, and good product quality effectively reduces the weight of product, and material uses The polyolefin of crosslinking has good anti-flaming thermal-insulation effect, can effectively prevent the secondary harm that cable fire is caused, can have The reduction electromagnetic radiation of effect, can effectively utilize the resistance to of nitrile rubber at insulating barrier outer surface one layer of nitrile rubber layer of parcel simultaneously The performance of weather oily, ageing-resistant, resistance to, makes cable life longer, uses more stable.

The present invention compared with prior art has the advantages that

1, the product of the present invention is provided with rational layout designs, can effectively reduce the processing technique of three-core cable, logical Cross disposable expressing technique with regard to stranding, the effective technological process of production shortening cable, led by direct expressing technique Composite insulation layer and linkage section on body, have production efficiency high, and good product quality effectively reduces the weight of product, and material is adopted With the polyolefin of crosslinking, there is good anti-flaming thermal-insulation effect, can effectively prevent the secondary harm that cable fire is caused, energy Effectively reduce electromagnetic radiation；

2, simultaneously insulating barrier outer surface wrap up one layer of nitrile rubber layer can effectively utilize nitrile rubber oil resistant, resistance to always Change, the performance of resistance to weather, make cable life longer, use more stable.
