Bimetal Parallel Groove Clamp — CAPG Series
CAPG bimetal parallel groove clamp for reliable tapping and joining of overhead conductors.
Single-bolt / double-bolt / tri-bolt options to match mechanical load and fault-level requirements.
Grooved, tin-plated contact surfaces for low resistance and corrosion protection.
Compatible conductor ranges from Cu 6–240 mm² and Al 16–300 mm² (model-dependent).
Overview — CAPG Series Bimetal Parallel Groove Clamps
CAPG clamps are copper–aluminium parallel groove clamps designed for
tapping and splicing of distribution lines. The bimetal construction and grooved profile provide
stable, low-resistance contact between dissimilar conductors, while the bolt options (single, double,
tri-bolt) offer the required mechanical strength and fault-current capability.
Body: Aluminium alloy with copper contact plate (bimetal) |
Bolts/Nuts: Hot-dip galvanized steel |
Application: Cu/Cu, Al/Al, and Cu–Al transitions on overhead lines

Installation Notes
- Clean conductor and apply oxide-inhibiting compound for Al or Cu–Al transitions.
- Fit conductors in parallel grooves; tighten bolts evenly to specified torque.
- Re-tighten after thermal cycling if required by local standards.
