The main structural material of electric wires and cables

2020/03/02

Wires and cables are used to transmit electrical energy, information and wire products for electromagnetic energy conversion.The broad sense of wire and cable is also referred to as cable, narrow sense of cable refers to 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 sheathing. Cables may also have additional conductors without insulation.

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

The structural components of wire and cable products can be divided into four main structural components: wire, insulating layer, shielding and protective layer, as well as filling element and pulling element.According to the requirements and applications of the products, 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 of cable products accounts for 80-90% of the total manufacturing cost.2 it is the category that USES material, breed is very much, performance requirement is special high, if conductor USES copper, the purity that asks copper wants to be in 99.95% above, some products should use anoxic 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 benefit of wire and cable manufacturing enterprises is also closely related to the selection, processing and production management of materials can be scientific material savings.

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

The materials used for cable products can be divided into conductive materials, insulating materials, filling materials, shielding materials, protective materials, etc.But some of the materials are common to several structural parts.In particular, thermoplastic materials, such as polyvinyl chloride, polyethylene, etc. can be used on insulation or sheath as long as part of the formula is changed.

The materials used in the manufacture of cable products cover a wide range of categories, especially the variety and specification.

3. Name and materials of product structure

(1) wire: the most basic and essential component of the product for the transmission of current or electromagnetic wave information.

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

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

(2) insulation layer: it is the component that covers the periphery of a wire and ACTS as electrical insulation.Namely, it can ensure that the transmitted current or electromagnetic wave and light wave only travel along the wire and do not flow out, and the potential on the conductor can be isolated, which not only ensures the normal transmission function of the wire, but also ensures the safety of external objects and human beings.The conductor and the insulating layer are two basic components of the cable products.

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

(3) filling structure: many wire and cable products are multi-core. When these insulated wire cores or wires are combined into cables, one is that the shape is not round and the other is that there is a large gap between the insulated wire cores. Therefore, it is necessary to add filling structure when forming cables.

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 separated from each other between different wire pairs.It can be said that the shielding layer is a kind of "electromagnetic isolation screen".Conductor shielding and insulation shielding of high voltage cables are used to homogenize the distribution of electric fields.

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

(5) protective layer: when the wire and cable products are installed and operated in various environments, they must have components that protect the whole product, especially the insulation layer. This is the protective layer.

Because the insulation material is required to have excellent electrical insulation properties, the purity of the material must be very high, the impurity content is very small;It is often unable to take into account its ability to protect the outside world, so for the outside world (installation, use and use) of various mechanical forces or resistance, resistance to atmospheric environment, resistance to chemicals or oil, the prevention of biological damage, and reduce fire hazards must be borne by a variety of protective structure.

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

(6) tensile components: typical structures are steel core aluminum stranded wire, fiber optic cable cable, etc.In short, tensile components play a major role in the development of special small, soft products that require multiple bends and twists at the same time.

Main material: steel wire
