Phase clamps for round conductors

Phase clamps for round conductors


Category:

The phase clamps for round conductors are manufactured in several types:
– Classic reduced phase clamp, Cr type (extrusion of aluminium alloy);
– Universal classic phase clamp, CCU type (extrusion of aluminium alloy);
– Automatic phase clamp, CA type (casting from aluminium alloy);
– Automatic extruded phase clamp, CAEr type (extrusion of aluminium alloy);
– Universal automatic phase clamp, CAU type (extrusion of aluminium alloy).

All types of phase clamps have a fixing system on the bar, consisting of a mobile die operated by a tightening screw. This screw is provided – to its extremity – with a bayonet coupling system which allows a quick and safe connection at the insulating stick. The automatic phase clamps are additionally provided with a special system which allows a preliminary fastening of the clamp on conductor (by acting the mobile die). This preliminary fastening is triggered by a hooking of the clamp on conductor and must be followed by a firm fastening obtained by screwing.
