Contact valves

Contact valves are designed to carry out branches from wires and connect wires to the terminals of the devices. Contact clamps are not designed for significant mechanical loads.

The force that provides the contact of the wire-clamp is carried out by tightening with bolts (bolt clamps) or crimping (hardware, branch pressed clamps).

When shining open switchgear, a minimum number of bolted contacts should be sought, which require periodic monitoring and tightening of the bolts.

In the transition from aluminum wires to copper terminals of the devices, the aluminum legs of the clamps have a copper coating. This connection avoids contact disturbance due to electrolytic corrosion, especially when moisture enters. Direct bolt connection of aluminum clamps with copper terminals of devices is unacceptable.
