Development history of silicone rubber composite high voltage standoff
Different types of silicone rubber composite insulators have different functions, and the structural height and creepage distance are also different. Silicone rubber composite insulators are mainly used in substations. They have good hydrophobicity, aging resistance, resistance to leakage tracking and electrical erosion, high tensile strength and bending strength, high mechanical strength, good impact resistance, shock resistance and anti-brittle fracture performance, light weight, easy installation and maintenance, and the installation dimensions of the upper and lower ends are the same as those of the corresponding porcelain post insulators, and can be used interchangeably.
Functions and characteristics of silicone rubber composite insulators
Silicone rubber composite insulators can effectively use narrow corridors to open voltage and transmit electricity. They are suitable for urban network technical transformation, can reduce the height of poles and towers, and can save a lot of manpower, material and financial resources. Due to its high bending strength, it can prevent the cascade fracture accidents that are easy to occur in porcelain crossarms. It is a product that cannot be replaced by porcelain crossarms; small size, light weight, strong shock and impact resistance, no manual cleaning required, providing guarantee for safe operation.
This product adopts an overall rod design, compact structure, high quality, and weight is 1/10 of the same grade porcelain and glass insulators. It is extremely convenient to transport and install. It is suitable for dirty areas, high mechanical tensile loads, large spans and compact lines. The pollution flashover voltage is 30%-50% higher than that of porcelain and glass insulators of the same grade. The performance is stable at an ambient temperature of -60 degrees to +200 degrees; the non-breakdown design is adopted, and there is no need to measure the zero value during operation.
The silicone rubber shed adopts an integral injection molding process, which solves the key problem of interface electrical breakdown that affects the reliability of composite insulators. The connection between the glass lead rod and the hardware adopts the most advanced crimping process, equipped with a fully automatic ultrasonic flaw detection system, with high strength, beautiful appearance, small size, light weight, and galvanized hardware to prevent rust. It can be used interchangeably with porcelain insulators. This product has a reliable structure, does not damage the core rod, and can give full play to its mechanical strength.
Excellent electrical performance, high mechanical strength, the tensile and bending strength of the epoxy glass lead rod carried internally is 2 times higher than that of ordinary steel, and 8~10 times that of high-strength porcelain materials, which effectively improves the reliability of safe operation.
Good pollution resistance, good pollution resistance, strong anti-pollution flashover, its wet withstand voltage and pollution withstand voltage are 2~2.5 times that of porcelain insulators with the same creepage distance. And no cleaning is required, and it can operate safely in heavy pollution.
Small size and light weight (only 1/6~1/9 of porcelain insulators of the same voltage level). Light structure, easy to transport and install.
The silicone rubber shed has good water-repellent properties, and its overall structure ensures that the internal insulation is not damp, and no preventive insulation monitoring test or cleaning is required, which reduces the workload of daily maintenance.
Good sealing performance, strong electrical corrosion resistance, the shed material has a leakage tracking resistance of TMA4.5 level, good aging resistance, corrosion resistance, and low temperature resistance, and can be used in -40℃~-50℃ areas.
It has strong impact resistance and shock resistance, good anti-brittleness and creep resistance, is not easy to break, has high bending resistance and torsional strength, can withstand internal pressure, has strong explosion-proof force, and can be interchanged with porcelain and glass insulators.
The silicone composite insulator series products have better mechanical and electrical properties than porcelain insulators, with a large operating safety margin, and are updated products for power lines.
