Phase clamps for round-section conductors: multi-core flexible conductors, rigid bars, T-type fixed points

Lightweight Universal Classic Phase Clamps CCTU/E for round conductors are applied on the conductor by attaching / hanging on the conductor bar / piece.
The clamps are screw-fastening clamps, allowing the tightening of conductor bar or piece between the clamp’s body and the mobile jaw. The tightening force is provided by the clamping torque of the clamp’s driving screw. Both the clamp body and the jaw are aluminium alloy die cast items. The clamp’s driving screw has a “RO bayonet” end. Having small dimensions and lightweight construction, these clamps are recommended for use in low voltage power installations and in other power installations where the spaces between the conductor bars are extremely small or where the application of the clamp is made from a small distance.
The dismounting of the clamp from the conductor is similar for all types of screw-fastening clamps, more exactly the driving screw is unscrewed, the mobile jaw is lowered until there is sufficient space to detach the clamp from the conductor bar / piece.

The automatic phase clamp for round conductors CA is also a screw-operated fastening clamp, the conductor being tightened between the clamp’s body and its mobile jaw. Additionally, this type of clamp is provided with a system of levers and springs that allows the automatic closing of the clamp’s jaw upon the contact of levers with the conductor (pre-fastening of the clamp on the conductor). Subsequently to this phase, which provides much easier handling the clamp, the fixing of the clamp must be completed through the tightening of the driving screw to the proper torque specification. Similar to the classic clamp, the automatic clamp includes two aluminium alloy cast items and a driving screw provided with a ‘’RO bayonet’’ end.

The dismounting of the clamp from the conductor is similar to the one used by the classic clamp, more exactly the screw is unscrewed, the jaw is lowered until there is sufficient space to lift the clamp from the round conductor.
