Phase clamps for MV/HV overhead lines


Category:

Phase clamps for medium/high voltage overhead lines are manufactured in two types, with specific adaptations to the use conditions. The main parts of the clamp are made of aluminium alloy.

Phase clamps for medium/high voltage overhead lines are manufactured in several types:
– for MV overhead lines – self-locking clamp;
– for MV overhead lines – automatic self-locking clamp (CAA) for clamps dispenser;
– for MV overhead lines – automatic self-locking clamp (CAA) for mounting adaptor;
– for HV overhead lines – automatic self-locking clamp (CAA) for special adaptor.
