LH1522 Irradiation Crosslinked Silicone Rubber Self-melting Belt

1. Product introduction Our company independently developed and developed a new type of insulation material for the requirements of insulation materials in high-low temperature, high pressure and strong ultraviolet all-weather conditions of the power industry and the needs of the domestic aircraft manufacturing and maintenance industry: LH1522 irradiation cross-linked silicone rubber Melt band. Through comparison with Russia, 3M company product testing and analysis and the national military backbone enterprise Shenyang Dawn Aircraft Manufacturing Company installed bench test, its performance indicators have fully met and partially exceeded the Russian and 3M product indicators, filling the domestic gap. At present, the product is widely used in the aircraft manufacturing industry. In the power industry, it is recognized as an innovative and technologically advanced new insulation material and is recognized and gradually adopted by the power departments at all levels. Up to now, there have been successful applications on 380V, 10kV, 35kV, 110kV, 220kV voltage levels.

Product Description

1. Product introduction
Our company independently developed and developed a new type of insulation material for the requirements of insulation materials in high-low temperature, high pressure and strong ultraviolet all-weather conditions of the power industry and the needs of the domestic aircraft manufacturing and maintenance industry: LH1522 irradiation cross-linked silicone rubber Melt band. Through comparison with Russia, 3M company product testing and analysis and the national military backbone enterprise Shenyang Dawn Aircraft Manufacturing Company installed bench test, its performance indicators have fully met and partially exceeded the Russian and 3M product indicators, filling the domestic gap. At present, the product is widely used in the aircraft manufacturing industry. In the power industry, it is recognized as an innovative and technologically advanced new insulation material and is recognized and gradually adopted by the power departments at all levels. Up to now, there have been successful applications on 380V, 10kV, 35kV, 110kV, 220kV voltage levels.
2, performance characteristics
Applicable to low pressure or high voltage (distribution network 380V-330kV), indoor or outdoor, the bare conductor and its contact shape are regular, can be insulated and treated by winding.
1. High and low temperature resistance, capable of working at -60~250 °C for a long time;
2, UV resistant, can work in the outdoor sun for a long time without aging and no cracking;
3, the surface is not coated with any adhesive glue (the stability of high temperature and ultraviolet light of any viscous glue is unstable, after running for about one year, the viscosity is lost and caused to fall off, which is through super strong vacuum adsorption physical properties and good self-melting Sexuality, ensuring long-term operation without loosening or falling off;
4, water, anaerobic, flame retardant (self-extinguishing from the fire) oxygen index> 29;
5, with super insulation, breakdown strength of 30kV / mm, this product is 0.8mm thick, suitable for 380V ~ 10kV voltage level, and 1.5mm thick, suitable for 35kV ~ 330kV voltage level. Protection 10kV voltage level can achieve 20kV/min insulation effect with only two layers of 0.8mm thick specification;
6, the operation is extremely simple, no need for heating, no tools;
7, can be used repeatedly, as long as the surface is cleaned (cleaning method is simple, just wipe with a wet rag to dry) can be repeatedly stripped to facilitate testing equipment replacement equipment, and then wrapped around the insulation seal;
8. It has good heat dissipation and thermal conductivity, and the heat dissipation coefficient is larger than that of air medium; the live bare conductor protected by its insulation will not only heat up, but also increase the heat dissipation surface area, so it can directly measure the temperature of its insulation protection equipment;
9, the life is too long, for 10 years, does not fall off, the insulation strength does not decrease;
10, strong stretch, stretch ≤ 5 times long, loosen to rebound to the original length before stretching, can be used to protect any irregular shape of electrical equipment screw joints, thus solving the shape of prefabricated insulating cover The disadvantage of fixed site installation is not in place. Really for insulation purposes.
11. Compared with the insulation protection box of other materials: the material cost is low, saving more than 1/2;
12. Waterproof rating reaches IPX6. The high-low voltage electrical equipment's screw joints are vacuum-wrapped and insulated to avoid rust, heat and current carrying capacity caused by acid-base corrosion in the air.
Note: Waterproof grade IPX6: anti-strong water spray, nozzle diameter 12.5mm, nozzle to shell surface distance: 2.5mm~3m, water flow rate: 100L/min±5%, time 1min/m2 for at least 3min, no water influent Harmful effects.
