OEM/ODM Supplier China 36kv Pin Insulator - ANSI TR Series High Voltage Outdoor Station Post Ceramic Insulator – Johnson
OEM/ODM Supplier China 36kv Pin Insulator - ANSI TR Series High Voltage Outdoor Station Post Ceramic Insulator – Johnson Detail:
Performance
In power system, post insulator is widely used in bus and disconnector. During long-term operation, mechanical, thermal
Due to the comprehensive action of many factors such as electricity and environment, various physical and chemical changes will inevitably occur in insulator porcelain, resulting in electricity
The gas performance and mechanical strength decrease gradually with the increase of operation time.
The operation overvoltage is internal overvoltage, so the influence of tower height is not considered, while the lightning overvoltage is external overvoltage, and the tower height is considered. In addition, the overvoltage waveform of the operating overvoltage is closer to that of the power frequency voltage. Therefore, the zero value insulator will affect its discharge characteristics. Therefore, when calculating the tension insulator under the operating overvoltage, it is considered to add a certain number of zero value insulators more than the suspension string.
