The most widely used in Glass Insulator production lines are tempered glass insulators. We also sale standard disc Porcelain Insulator and standard disc type Suspension Insulator.
Standard glass insulators: U70, U100, U120
Breaking load between 40kN and 240kN
Frequencies up to 100 Hz are supported.
Temperature range is between -60°C and +50°C.
The insulators are made of an insulating element, a cap and a pin.
The cap and pin are made of high-strength hot galvanized cast-iron, with corrosion- resistant coverage, it can be of the type ball-socket or clevis-tongue.The lock, a split-pin is made of stainless steel or phosphor bronze.
