Special cables can be used in special occasions, and their functions also have special characteristics, such as high temperature resistance, strong acid and alkali resistance, termite prevention, etc. Among them, high-temperature resistant wires and cables are mainly used in fields such as energy development, steel, aerospace, oil extraction, and metal smelting. The low inductance cable has good heat dissipation effect, not only does it have a large flow of cooling water, but it also does not block or limit the current. Low noise cables are mainly used in fields such as medicine, industry, and national defense that require small signal measurements, and can detect low frequencies. In addition, there are functional wires and cables, as well as new green and environmentally friendly cables.

The development direction of special cables is diversified. The demand for lightweight and high-temperature resistant cables is particularly high. The demand for construction mainly includes double-layer flame-retardant and high-temperature resistant wires and cables, as well as low smoke and halogen-free environmentally friendly wires and cables, mainly to prevent fire and safety hazards. At present, most of them use radiation crosslinked or silane crosslinked wires and cables that are lightweight, small in size, and resistant to high temperatures. Among various types of special cables, high-temperature cables have a high market demand and are widely used in various short distance transmission of high currents, but are in short supply.

Ordinary cables are more diverse, including home decoration cables, electrical equipment cables, and power cables. Both in terms of temperature resistance and structure, they are different; The long-term allowable working temperature for home decoration wires is 70 ℃, which is mostly used for home decoration; And special cables are allowed to work at temperatures above 250 ℃ and are mostly used for outdoor installation, with a significant difference between the two. Although ordinary cables have the characteristics of flexibility, flame retardancy, fire resistance, acid and alkali resistance, they are not as effective as special cables such as fire-resistant cables, waterproof cables, armored cables, flexible cables, and ant proof cables.

Secondary products of special cables: armored cables, fire-resistant cables, flexible cables, fire-resistant cables, radiation cables, waterproof cables, rodent and ant resistant cables, pre branched cables, flame-retardant cables, intelligent security cables, etc.

Ordinary cable products: mineral cables, low smoke halogen-free cables, medium voltage cables, aluminum alloy cables, cross-linked cables, overhead cables, rubber sheathed cables, control cables, shielded cables, communication cables, home decoration cables, computer cables, photovoltaic cables, data cables, sheathed cables, power cables, audio cables, video cables, etc.
