Supporting clamps of types PG and PGG are designed for attaching conductors and lightning protection cables to insulating suspensions, as well as for directly attaching lightning protection cables to intermediate poles. The saddles and plates of the clamps are made from aluminum alloys. PGG-type clamps are equipped with a stamped eye, reducing the construction height of the insulating suspension. The "A" modification clamps feature a U-bolt intended for connecting a grounding clamp of type ZPS. The PG-30/12-20K model is distinguished by a special connector for installing an insulating rod during short-circuiting and grounding. The products are manufactured in accordance with TU 3449-001-52819896-2010.
