The CKRN12-12 indoor compressed-air load switch is suitable for three-phase high-voltage switchgear rated at 12kV and below, serving to control and protect electrical equipment such as transformers, cables, and overhead lines. It is particularly well-suited for terminal substations and box-type substations within urban and rural power networks. Furthermore, it is applicable for the control and protection of ring networks and dual-radial power supply units.

The CKRN25 indoor high-voltage vacuum load switch and the CKRN25-12D/T200-31.5 indoor high-voltage vacuum load switchfuse combination unit serve as control and protection devices for three-phase, 50Hz, 12kV AC distribution systems. These oil-free, non-toxic products pose no fire or explosion hazards and are extensively employed in industrial and mining enterprises, as well as in distribution substations within urban buildings.
