Description

One-time formed Acanthopanan trifoliatus (L.) Merr. two core aerial cable

Technical field

The present invention relates to the essential electronic element that electricity, metal wire or metal tape make, espespecially one-time formed Acanthopanan trifoliatus (L.) Merr. two core aerial cable.

Background technology

Cable is usually by the cable of the stranded similar rope of several or several groups of wires (often organizing at least two), often mutually insulated between group wire, and be often twisted into round a center, whole outside is surrounded by the cover layer of high-insulation, cable has interior energising, the feature of external insulation, the mode of production with most of electronic products that manufactures of electric wire is diverse, electronic product generally adopts and another part is assembled into parts, multiple parts refill and are made into separate unit product, product measures with number of units or number of packages, electric wire is with length for basic measurement unit, all electric wires are all from conductor processing, in the periphery of conductor layer by layer plus insulation, shielding, stranding, sheath etc. and make electric wire product, product structure is more complicated, the level of superposition is more many, the various equipment of workshop rationally must discharge by the technological process of product requirement, make the semi-finished product in each stage, sequentially circulate. equipment configuration to consider that production efficiency difference carries out the balance of production capacity, some equipment possibilities must configure two or multiple stage, the production capacity of production line just can be made to be balanced, thus the layout of the reasonable selection combination of equipment and production site, must balance according to product and volume of production and consider, organization management must be scientific and reasonable, careful accurate, strictly careful, operator must perform by technological requirement fastidiously, any one link goes wrong, capital affects the unobstructed of technological process, affect quality and the delivery of product, particularly multicore cable, some line to or elementary cell length short, or quality goes wrong, then whole cable will length inadequate, cause and scrap, otherwise, if certain element length is long, then must saw and cause waste, the mode of production of the continuous stack combinations of long length, make any one link in production process, some problems of instantaneous generation, whole cable quality will be affected, mass defect is more to occur at internal layer, and do not find in time to terminate producing, the loss so caused is more big, because the production of electric wire is different from modular product, refitting can be taken apart and change another part, the either component of electric wire or the quality problems of technical process, this root cable almost cannot be retrieved and make up, process afterwards is all very passive, it not that sawing short is exactly that degradation processes, scrap whole piece cable, it cannot take refitting apart, the quality management of electric wire, must pass through whole production process, quality management controlling unit will to whole production process tours of inspection, operator's self-inspection, upper and lower operation is examined mutually, this is to ensure that product quality, improve important guarantee and the hands section of Business Economic Benefit, the technique class that electric wire manufacture relates to is extensive, from the melting of non-ferrous metal and pressure processing, to plastics, rubber, the Chemical Engineering Technologies such as paint, the textile technology of wrapped, the braiding etc. of fibrous material, to the metal forming processing technique etc. of the wrapped of metal material and the vertical bag of sheet metal strip, welding, electric wire manufactures various materials used, and not only classification, kind, specification are many, and quantity is big. therefore, the consumption of various materials, reserve level, batch of material cycle must be appraised and decided with batch. simultaneously, resolution process to waste product, reclaim, recycling and waste disposal, an important content as management, carry out Material ration management, pay attention to saving work, during electric wire produces, turnover from raw material and various auxiliary material, storage, half-finished circulation the depositing to product of each operation, dispatch from the factory, mass flow is big, necessary rational deployment, dynamically management, electric wire manufacture uses the production equipment special with industry process characteristic, to adapt to the structure of cable products, performance requirement, meet continuous and high-speed production as far as possible the requirement of long length, thus defining the special equipment series of cable manufacturing. such as extruding machine series, drawing machine series, wire twisting machine series, winding machine series etc., the manufacturing process of electric wire is closely related with the development of special equipment, promotes mutually, new technology requirement, promotes generation and the development of new special equipment, in turn, the exploitation of new special equipment, improves again the promotion and application having promoted new technology, such as wire drawing, annealing, extrusion series line, the special equipments such as physical blowing production line, have promoted development and the raising of electric wire manufacturing process, have improve product quality and the production efficiency of cable.

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

Summary of the invention

One-time formed Acanthopanan trifoliatus (L.) Merr. two core aerial cable is the invention provides for the problems referred to above, this product processes is simple, easy to make, the mode using plastic extrusion replaces all techniques that stranding is later, greatly shorten production technology, reduce production cost, save substantial amounts of raw material, the effective weight controlling cable.

For solving the problems referred to above, the invention provides one-time formed Acanthopanan trifoliatus (L.) Merr. two core aerial cable, including big cable core, little cable core, conductor, cross-linked polrvinyl chloride layer, connect arc, body, it is characterised in that: being provided with three big cables core on body, three big cables core are that equilateral triangle is arranged, along left side, big cable core level is provided with to the right two little cables core, it is respectively arranged with connection arc between adjacent big cable core, little cable core, is respectively arranged with conductor in the middle part of big cable core, little cable core, outside conductor, is provided with cross-linked polrvinyl chloride layer.
