Explanation of the principle of irradiation
Irradiation cross-linking uses high-energy β-rays to form high-molecular radicals, and then the polymer radicals are reassembled and broken down into cross-linking bonds, so that the original linear molecular structure becomes a three-dimensional network molecular structure, and Constitutes cross-linking.
The wire and cable irradiated with the electron accelerator of this product is radiation processing. This technology integrates electronic technology, high-energy nuclear physics technology, vacuum technology, computer technology, radiation chemistry technology and wire and cable manufacturing technology, and is a model of today's high technology. The high-energy electron beam consumed by the electron accelerator acts on the inside of the polymer, causing the molecular structure of the polymer to change, from the original linear macromolecule to an insoluble and insoluble three-dimensional network structure, so that the material has special heat resistance , Chemical resistance, radiation resistance, high flame resistance, high strength.
Product main features:
1. Good heat resistance of the product: Radiation cross-linking can obviously improve the heat resistance of the cable. For example, after the polyethylene material is crosslinked by irradiation, the temporary allowable temperature can be increased from 60 to 70 ° C to 90 to 150 ° C, and the short-circuit temperature can be increased from 160 ° C to 250 ° C.
2. The current carrying capacity of the cable is increased: the cross-linked current carrying capacity per unit conductor cross section of the irradiated cross-linked wire and cable is increased by about 20% compared with ordinary wire and cable.
3. It has insulation function and electrical function.
4. The machine has high strength, good aging resistance, chemical shaking resistance and environmental stress cracking resistance.
5. Improve the flame retardant function.
6, high safety, PVC cable extinguishes toxic gases harmful to the human body, at the same time, its service life extension, can reach 40 years.
The application range of irradiated cross-linked wires and cables is very common. At present, it is mainly used in electric power, communications, electronics, chemicals, vehicles and ships, aerospace, military, oil mining, subways and household appliances.
The temporary allowable temperature of the conductor is 90 ° C;
The temperature of the cable conductor is 250 ℃ during a short circuit (longer duration does not exceed 5s);
The ambient temperature should not be lower than 0 ℃ when laying the cable;
Cable bending radius: multi-core is not less than 15 times the outer diameter of the cable; single-core is not less than 20 times the outer diameter of the cable.
