1.GB Shackle Insulators are small, generally used for low voltage applications, and can be found on distribution lines. They are designed to change the direction of the wire or to support a dead-end or terminal pole. The "GB" indicates compliance with Chinese standards.
2.GB Spool Insulators, similar to shackle insulators, are used in low-voltage distribution networks. They are designed to support wires on crossarms of utility poles. The spool shape allows for easy wire wrapping and unwrapping during installation or maintenance.
