The portable single-phase short-circuiting device with extruded automatic phase clamp (type CAEr) is used on round conductors in substations.
The extruded automatic phase clamp (CAEr) has an extruded aluminium-alloy body and a clamping screw with a bayonet coupling at one end for connection to the insulating stick.
