High strength APG AL alloy parallel groove clamp for connecting overhead conductors

High strength APG AL alloy parallel groove clamp for connecting overhead conductors

Adaptable to use as an oblique tap or parallel connector, the parallel groove clamp (PG Clamp) is designed to connect two conductors in parallel and especially used to hold transmission conductors in parallel in transmission lines.

Made up of high-strength aluminium alloy bolts, the parallel groove clamps are designed to maintain high contact pressure during cooling and heating cycles.

The 396.6, 395.5, and 490.0 are the rotational tightening method for clamp which provides accurate torquing.

The main feature of the parallel groove is its easy installation, simple structure and bolt-type power connector, which makes it a unique product. For a reliable tightening, a spring washer and pressure pad are inserted under the bolt head of the clamp.

The upper and lower regions are the two parts of the connector while they have two parallel grooves to receive the aluminium clamps, which are made out of high strength aluminium. In bimetallic clamps, the high strength electrolytic copper makes the copper clamp.
