ANSI 55-6 Pin Type Porcelain Insulator
- ANSI 55-6 pin porcelain insulators are mainly used for medium voltage distribution lines.
- Ceramic pin insulators are installed on the needle sockets on the cross arms of electric poles.
- The upper end of the insulator is equipped with a groove, through which the wire passes and is tied to the insulator with a wire of the same material as the wire.
- Capable of withstanding physical stress and environmental factors, prolonging service life.
- Designed to perform under varities of weather conditions.
- Brand: QOCI
- Catalog ID: ANSI 55-6
- Type: Pin Insulator
- Material: Porcelain
- Place of Origin: Jiangxi
