Aluminium Parallel Groove Clamp — APG Series
APG aluminium PG clamp for mechanical and electrical connection of overhead aluminium conductors.
Compact, corrosion-resistant design with single or double-bolt tightening.
Full range covers Al 16–300 mm², ideal for distribution and transmission lines.
Provides stable, low-resistance performance for both line and jumper applications.
Overview — APG Series Aluminium Parallel Groove Clamps
APG aluminium parallel groove clamps provide a reliable and economical way to
connect or branch aluminium conductors in overhead line systems. The grooved aluminium body and
galvanized steel bolts ensure durable compression, minimal contact resistance, and resistance to
corrosion or thermal cycling.

Installation Notes
- Clean conductor strands before clamping to remove oxide layers.
- Apply anti-oxidant compound where necessary for improved conductivity.
- Tighten bolts evenly and alternately to the specified torque values.
- Re-check after first load cycle or temperature change to ensure contact stability.
