The major difference between irradiated wires and cable […]
The major difference between irradiated wires and cables and ordinary cables is the different manufacturing processes used.
Irradiation technology: It converts power frequency and low-voltage electric energy into high-frequency electric energy, and then obtains high-energy and high-current electron rays through a certain technology, and then uses an electron accelerator to generate high-energy electron beams, and then uses high-energy electron beams to bombard wires and cables Insulating layer and protective cover, their molecular structure is changed, after recombination, a new three-dimensional network molecular structure is formed, and then a new cable cross-linked structure is formed.
This new technology of wire and cable has many excellent qualities:
1: After the irradiation process, the material molecular structure of the insulating layer and the protective cover becomes a three-dimensional network structure. Its high temperature resistance class is higher than that of ordinary cables, and the temperature resistance class is as high as 125°C. The current-carrying capacity is increased by 1.2 to 1.6 times, which greatly improves the anti-overload capability of the cable.
2: The insulation resistance is larger and safer.
3: Longer service life, environmental protection and safety, because the materials are all halogen-free materials.
4: The strength and elasticity of the cable are obviously improved, and the wire and cable resistance to pull and wear resistance are also improved.
5: Because of the performance, the price is relatively high.
For the home improvement environment, the use is relatively small, and household requirements have higher requirements for quality, environmental protection, and service life. It is more economical to choose this radiating cable in the long run, although the initial investment is higher.
Generally, the cables and wires can be distinguished by color:
For the selection of wire diameter, please refer to the following table for selection:
The radiation processing of wire and cable generally refers to the formation of cross-linked covalent bonds between the polymer materials of the insulating layer and the sheath layer of the wire and cable under the irradiation of high-energy electron beams to form a network or body structure. This process is also called Irradiation crosslinking. The strength, elasticity and hardness of the wire and cable modified by irradiation crosslinking have been improved, solvent resistance and environmental stress resistance.
The European standard and the national standard have the same color standard for the zero and live wire, both are brown: live wire; blue: neutral wire; yellow and green: ground wire.
