2025-04-08

The pin-type porcelain insulator P - 20T has the following performance characteristics:
Good electrical properties: It can withstand high frequency voltage, and can effectively isolate the conductor from the tower under normal operating conditions, preventing current leakage. At the same time, it has a certain lightning impact withstand voltage and impact withstand voltage capability, which can resist the impact of lightning and system operation overvoltage, and reduce the occurrence of flashover accidents. Its creepage distance is designed reasonably, it can maintain good insulation performance in polluted environment, reducing the risk of pollution flashover.
High mechanical strength: Adopting ceramic material and reasonable structure design, it can the gravity and tension of the conductor, as well as the mechanical load generated by wind, icing, etc. It has high bending failure load capability, and can maintain stability under various conditions, and is not prone to mechanical damage, ensuring the safe operation of power lines.
Stable thermal properties: It has good heat resistance and thermal shock resistance, can the cold and heat changes in the outdoor environment, and is not easy to crack after multiple cold and heat cycles, and can work stably under different seasons and climatic conditions, that the performance of the insulator is not affected by temperature.
Strong aging resistance and weather resistance: Ceramic materials have good chemical stability and anti-aging performance, in longterm outdoor operation, it can resist the erosion of natural factors such as sunlight, wind and rain, sand and dust, and is not prone to aging, embrittlement and phenomena, with a long service life, which can reduce the frequency of insulator replacement and reduce maintenance costs.
