The main structural material of wire and cable

2020/03/12

Wire and cable for the transmission of electrical energy, information and electromagnetic energy conversion wire products.The generalized wire and cable is also referred to as the cable, the narrow sense of the cable refers to the insulated cable, it can be defined as: by the following parts of the assembly;One or more insulated wire cores and their respective possible cladding, total protection and outer sheath. Cables may also have additional conductors without insulation.

The majority of wire and cable products are products with the same section shape and long strip, which is determined by the characteristics of the system or equipment that is used as a forming line or coil.Therefore, to study and analyze the structure and composition of cable products, we only need to observe and analyze from its section.

In general, the structural elements of wire and cable products can be divided into four main structural components: wire, insulation layer, shielding and protective layer, as well as filling element and tension bearing element.According to the use of the product requirements and applications, some of the product structure is very simple.

2. Cable materials

In a sense, the wire and cable manufacturing industry is a material finishing and assembly industry.First, the material consumption is huge, the material cost in the cable product should account for 80-90% of the total manufacturing cost;2 it is the class that USES material, breed is very much, performance requirement is particularly high, if conductor USES copper, the purity that asks copper wants to be in 99.95% above, some products should use without oxygen high pure copper;Third, the selection of materials will have a decisive impact on the manufacturing process, product performance and service life.

At the same time, the benefits of wire and cable manufacturing enterprises are also closely related to the selection of materials, processing and production management can scientifically save materials.

Therefore, in the design of wire and cable products must be carried out at the same time with the selection of materials, generally adopt the selection of several materials, through the process and performance screening test to determine.

The materials used for cable products can be divided into conductive materials, insulation materials, filling materials, shielding materials, protective materials, etc.But some of these materials are common to several structural parts.Especially thermoplastic materials, such as polyvinyl chloride, polyethylene, as long as the change of part of the formula can be used in insulation or sheath.

Cable products used in the manufacture of materials involved in a very wide range of categories, varieties and specifications in particular.

3. Name and material of product structure

(1) wire: the most basic and essential main component for the product to carry out the current or electromagnetic wave information transmission function.

Main material: conductor is the abbreviation of conductive wire core, made of copper, aluminum, copper clad steel, copper clad aluminum and other nonferrous metals with excellent conductive properties, with optical fiber as conductor.

Bare copper wire, tin wire;Single branch line and stranded line;Stranded tin wire.

(2) insulation layer: it is the component which plays the role of electrical insulation around the periphery of the conductor.Can ensure that the transmission of the current or electromagnetic wave, light wave only along the wire travel and not flow out, the potential on the conductor can be isolated, that is, both to ensure the normal transmission function of the wire, and to ensure the safety of external objects and people.Conductor and insulation layer are the two basic components that constitute the cable product.

Main materials: PVC, PE, XLPE, polypropylene PP, fluoroplastic F, rubber, paper, mica tape

(3) filling structure: many wire and cable products are multi-core. After forming these insulation cores or wires into cables, the shape is not round, and there is a large gap between the insulation cores. Therefore, the filling structure must be added into the cable.

Main material: PP rope

(4) shielding: a component that isolates the electromagnetic field in the cable product from the external electromagnetic field;Some cable products also need to be isolated from each other within the different cable pairs.It can be said that the shielding layer is a kind of electromagnetic isolation screen.The conductor shielding and insulation shielding of high-voltage cables are for the purpose of homogenizing the distribution of electric field.

Main materials: bare copper wire, copper clad steel wire, tinned copper wire

(5) protective layer: when the wire and cable products are installed and run in a variety of different environments, there must be a protective component for the whole product, especially for the insulation layer, which is the protective layer.

Because the requirement insulation material has the fine each kind of electricity insulation performance, then must request the material the purity extremely high, the impurity content extremely tiny;Often can not give consideration to its ability to protect the outside, so for the outside (that is, installation, use and use) a variety of mechanical force or resistance, atmospheric environment, chemical or oil resistance, biological damage prevention, and reduce the harm of fire must be undertaken by a variety of protective structure.

Main materials: PVC, PE, rubber, aluminum, steel belt

(6) tensile components: the typical structure is steel core aluminum wire, fiber optic cable cable, etc.In short, the tensile elements play a major role in the development of special small, soft products that require multiple bending and twisting.

Main material: steel wire
