Product Description

ANSI 56-2 Product Description


About the Porcelain pin type Insulator

As the name suggests, the pin type insulator is mounted on a pin on the crossarm on the pole. There is a groove on the upper end of the insulator. The conductor passes through this groove and is tied to the insulator with annealed wire of the same material as the conductor. Pin type insulators are used for transmission and distribution of electric power at voltages up to 33 kV. Beyond operating voltage of 33 kV, the pin type insulators become too bulky and hence uneconomical.

- Advantages of Porcelain pin type Insulator
- High reliability through accumulated technology
- Excellent long-term performance
