ZW8-12F(G) intelligent outdoor high-voltage vacuum circuit breaker (hereinafter referred to as intelligent circuit breaker) is used for three-phase power system with AC 50Hz and voltage 10-12kV. It is used to disconnect and close load current. It has overload and short-circuit protection functions, quick-break protection function, time-limited delay protection function, automatic reclosing function, and can also be equipped with lightning arrester or disconnector (i.e. circuit breaker and disconnector combination, hereinafter referred to as "combined intelligent circuit breaker") according to user needs. The intelligent circuit breaker has its own power supply and can be remotely controlled nearby. It is equipped with CT and PT interfaces to meet telemetry requirements.

Three phase AC system (50Hz, 10-12kV), load current switching, overload and short circuit protection. Fast breaking protection+time limited delay protection, automatic reclosing function, optional lightning arrester or isolation switch (combination intelligent circuit breaker), built-in operating power supply, supports near/remote control, equipped with CT/PT interface, meets telemetry requirements

ZW43A-12F outdoor vacuum circuit breaker is used to make and break load current, overload current and short-circuit cur rent in 12kV, AC 50/60Hz power system. It is applicable for substations, industry and mining, urban and rural electricity power networks, especially for occasions with frequent operation and automatic power distribution network.

The floor-standing demarcation switch integrated prepaid metering device is a product that changes the column-mounted high-voltage metering, switch, and control box into a cabinet-type structure. It is composed of an integrally cast dry-type high-voltage metering box and a ZW32F type intelligent demarcation switch. The box is made of stainless steel or iron plate sprayed plastic. This product is easy to install in structure and has a beautiful appearance. The high-voltage part is isolated from the low-voltage meter room, and the high-voltage room cannot be opened for operation when the equipment is energized. The high-voltage room door can only be opened in the event of a power outage, which is safe and reliable. The product occupies a small area and is a combination product used in living areas, industrial and mining enterprises and box-type transformers.
