Product Details

Overview

This product is suitable for power plant facilities. It possesses excellent water repellency, aging resistance, resistance to tracking and electrical erosion, high strength and flexural strength, high mechanical strength, good impact resistance, shock resistance, and resistance to brittle fracture. It is lightweight and easy to install. Its top and bottom mounting dimensions are compatible with corresponding ceramic support pillars.

They are the same size and can be used interchangeably. They are also the same size as the corresponding ceramic pins and can be used interchangeably.

Overview

This product is suitable for electrified railway tunnels with complex operating conditions, effectively preventing flashover accidents and reducing cleaning and maintenance workload. Due to its small size, it is an irreplaceable product compared to porcelain and glass insulators when tunnel clearance is limited.
