Special electrical insulation special transparent material for UHV power equipment [authoritative release]
Optical grade ultra-thick polycarbonate sheet is a special transparent material for electrical insulation for UHV power equipment.
Optical grade ultra-thick polycarbonate sheet can withstand ultra-high voltage 5WV 10,000 volts, which is currently my country's world-class standard in ultra-high voltage power transmission. With excellent physical properties, mechanical properties and easy processing properties, it is a special industrial transparent material with excellent comprehensive properties in transparent materials.
The electrical insulation performance of polycarbonate is determined by its own high molecular amorphous polymer material. It is a high molecular transparent insulating material with excellent electrical performance. Its dielectric constant is 2.96, and its resistivity according to IEC 60093 standard is 2.17×10^16 , The dielectric strength is higher than 16.30KV/mm. The electrical resistance of polycarbonate sheet is significantly better than that of polyester and aromatic fiber insulation materials, especially in the field of high-end optical transparent insulation materials.
Optical grade ultra-thick polycarbonate sheet has excellent heat and cold resistance properties, and can be used stably for a long time in a wide temperature environment from -60°C to 125°C, embrittlement temperature -130°C, heat distortion temperature 135°C-140°C .
Optical grade ultra-thick polycarbonate sheet ultra-high polymer insulation material, has good electrical insulation, optically pure high-definition high temperature and high temperature resistance, withstands high temperature of 130 degrees Celsius and ultra-low temperature of minus 120 degrees Celsius, wide temperature adaptability, can be used in complex complex Use in temperature environment, resist electrical aging, maintain stable electrical and mechanical properties.
Optical grade ultra-thick polycarbonate sheet has a minimum thickness of 30MM mm and a maximum thickness of 450MM. The thickness of commonly used materials is 30MM mm, 35MM mm, 40MM mm, etc. Good and easy processing (including cutting, drilling, polishing, drilling, turning, milling, boring, etc.), with high mechanical strength, is a high-end product of optical insulating boards and temperature-resistant materials.
