Description

A kind of reinforced mobile cable

Technical field

The utility model relates to industrial cable technical field, especially a kind of reinforced mobile cable.

Background technology

The electric wire product overwhelming majority is cross section (cross section) shape identical (ignoring the error produced because of manufacture), product in strip, and this is owing to being that the feature used as forming circuit or coil determines in system or equipment.So research and analyse the structure composition of cable products, only observation analysis need be carried out from its cross section.The structural detail of electric wire product, can be divided into wire, insulating barrier, shielding and sheath this four primary structure parts and packing elements and tension component etc. generally.According to instructions for use and the application scenario of product, some product structures are very simple.Cable material is said in a sense, and electric wire manufacturing is the industry of a material fine finishining and assembling.One is that material usage is huge, and the Master Cost in cable products will account for the 80-90% of total manufacturing cost; Two is that the classification of material therefor, kind are very many, and performance requirement is high especially, and as core copper, require that the purity of copper will more than 99.95%, some products will adopt anaerobic high purity copper; Three is that selecting of material on the performance of manufacturing process, product and can play conclusive impact useful life.Meanwhile, the benefit of electric wire manufacturing enterprise also with the selecting of material, to process and scientifically can to save material in production management closely related.Therefore, design electric wire product time must carry out with selecting of material simultaneously, generally take to select different materials, by technique and with performance screening test after determine.Cable products material uses position and function by it, can be divided into electric conducting material, insulating material, packing material, shielding material, jacket material etc.But wherein some material is that several structural member is general.Especially thermoplastic, if as the changing section such as polyvinyl chloride, polyethylene Formulation Ingredients just can be used on insulation or sheath on.Widely, description (trade mark) is many especially for the class that in cable products manufacture, material therefor relates to.3. the title of product structure and material (1) wire: product carries out the most basic requisite main member of electric current or electromagnetic wave information transfer function.Main material: wire is the abbreviation of conductive wire, and the non-ferrous metal excellent with electric conductivities such as copper, aluminium, copper covered steel, copper cover aluminum is made, using optical fiber as wire.There are bare copper wire, tinned wire; Single branch line, twisted wire; Tinned wire after strand.(2) insulating barrier: be coated on the component that wire periphery plays electric insulation effect.The electric current that transmits or electromagnetic wave can be guaranteed, light wave only advances along wire and do not flow to outside, the current potential (namely to potential difference, i.e. voltage that surrounding objects is formed) that core has can be isolated, namely should ensure the normal transmission function of wire, guarantee the safety of external object and the person again.Wire and insulating barrier form prerequisite two basic building blocks of cable products (except bare wire class).Main material: PVC, PE, XLPE, polypropylene PP, fluoroplastics F, rubber, paper, mica tape (3) interstitital texture: a lot of electric wire product is multicore, by these insulated conductors or line to after stranding (or the repeatedly stranding that divides into groups), one is profile not rounding, and two is leave very large space between insulated conductor, therefore must add interstitital texture when stranding, interstitital texture is to make the relative rounding of laying up diameter be beneficial to band, squeeze jacket.Main material: PP rope (4) shielding: be a kind of component electromagnetic field in cable product and extraneous electromagnetic field being carried out isolate; By cable products not collinear mutually isolated to also needing between (or line group) therein.Can say that screen is a kind of " electromagnetic isolation screen ".The core shielding of high-tension cable and insulation shielding are the distributions in order to homogenizing electric field.Main material: bare copper wire, copper covered steel wire, tinned wird (5) sheath: when electric wire product installation and operation is in various different environment, must have Total Product, particularly to the component that insulating barrier shields, Here it is sheath.Because require that insulating material has excellent various electrical insulation capabilities, then necessarily require the very high purity of material, impurity content atomic; Often cannot take into account its protective capability to external world; so for extraneous (namely install, use occasion and use in) various mechanical force bear or resistance, resistance to atmospheric environment, chemical-resistant resistance or oils, preventing biological infestation, and the harm etc. reducing fire all must be born by various shielding layer structure.Main material: PVC, PE, rubber, aluminium, steel band (6) tensile elements: typical structure is steel reinforced aluminium conductor, optical fiber cable cable etc.In a word, soft type tiny in the special type developed in recent years, requires that repeatedly in the product that curved, distortion uses, tensile elements plays a part main simultaneously.Current industrial cable is more, portable processing is also more and more flourishing, rolling and the uncoiling of cable is just related in the process of movement, rolling and uncoiling can reduce the useful life of cable frequently, can not meet the demand of modern people, the technology being therefore badly in need of a kind of improvement solves above-mentioned technological deficiency.

Utility model content

The utility model provides a kind of reinforced mobile cable.

The technical scheme that the utility model proposes for above-mentioned technological deficiency is:

A kind of reinforced mobile cable, comprise restrictive coating, packed layer, wire and tensile layer, described restrictive coating inside is provided with packed layer, is connected between described restrictive coating and packed layer by tensile layer, be provided with multiple wire and multiple tensile cord in described packed layer, described wire comprises core and insulating barrier.
