Special cable
Apr 14, 2018

Wire and cable is a series of products with unique properties and special structure, the equivalent of ordinary wire and cable quantity bedding face is wide, with high technical content, use more strict conditions, the characteristics of small batch and high added value. New materials, new structures, new processes and new designs are often used. Special cable is a special purpose, can be used in certain occasions cable that has a specific purpose, such as high temperature resistant, resistant to acid and alkali, the termite, and used in ships, including aircraft plant wire and cable. This kind of wire and cable can be divided into the following four types:

1. High temperature wire and cable.

Aerospace, locomotive, energy, steel, non-ferrous metal smelting, oil extraction, motor and other fields need to use high-temperature wire and cable. Long-term continuous working temperature of 125 degrees, 135 degrees, 150 degrees, 180 degrees, 200 degrees, 250 degrees and 250 degrees or more resistant to high temperature wire and cable, at present commonly used are radiation crosslinked polyolefin, silicone rubber, fluorine resin, polyimide, mica, magnesium wire and cable, etc.

Special electric wire and cable for use and structure.

1. Low inductive cable.

There is a strong electricity and weak electricity, here is a strong electricity low - sense cable. The cable with a heat dissipation device, used for all kinds of resistance welder, arc welder and pneumatic electrode holder connected between the new type of low water cooled cable, has simple and reasonable structure, large cooling water circulation, will not become blocked block and the limit of flow phenomenon, good heat dissipation effect, long service life, etc.

3. Functional wire and cable.

 Contain fluorine resin to control and stabilize the cable at 135 degrees.

A 135-degree automatic temperature control cable composed of polyvinylidene fluoride (PVDF)/fluorinated rubber alloy/carbon black multiplex composite. The thermal process is different, showing different levels of PTC conductivity and conductivity stability, which is due to the influence of the substrate crystallization degree and crystalline morphology on the insulation of different cooling speeds.

4. New green insulated electric wire and cable.

 The CMP cable

Can pass UL highest flame retardant grade standard cable, for CMP cable. By du help, lang, and BICC three companies combined a lot of fire test for wire, cable and study on the outside of the normal cable crowded on a thin layer of FEP (F46) layer, which can meet the requirements. In general, is the base material of low smoke zero halogen polyolefin, it has higher fuel quantity of heat, is highly combustible, so they are mixed with filler metal hydrate, to curb its flammability, but the water of hydration, after running out can cause burning fiercely. However, FEP burns very little and does not burn.
