The FZW28-12F 12KV Outdoor Demarcation Vacuum Load Break Switch LBS, as the boundary, is designed for outdoor installation on columns and can be operated manually or electrically. This switch utilizes the Corporation's VSP5-12 technology, making it a maintenance-free load switch. It uses vacuum arc extinguishing and SF6 gas for ground and phase insulation. This product conforms to the standards of GB3804 for high voltage AC load switch and GBT high voltage switchgear and control equipment.

Arc extinction and harmonic elimination cabinet During regular functioning, the microcomputer controller constantly monitors the voltage signal received from PT. Suppose the system experiences PT disconnection, single-phase metal grounding, or single-phase arc grounding. In that case, the auxiliary secondary open triangle voltage will promptly shift from a low to a high level. The microcomputer controller will then activate. It will determine the type and phase discrepancy based on the alteration in the PT secondary voltage

ZCW10-40.5G /T1600-31.5 Outdoor high-voltage SF6 open type combination electrical appliances is a complete set of units using air as external insulation SF 6 gas as arc extinguishing medium Combined electrical appliances.The control and protection of the three-phase AC 40.5kV transmission anddistribution system can also be used to connect circuit breakers and open and close capacitor banks.Suitable for the land shortage of urban substation, enterprise substation, mountain substation.

12KV Outdoor VCB Vacuum Circuit Breaker, a versatile piece of outdoor power distribution equipment, is designed for systems with a rated voltage of 10-12kV. It is a reliable choice in transformer substations, industrial and mining facilities, and county electric networks, adapting to the specific needs of each application to protect and manage power distribution. This circuit breaker, functioning as a ring network power supply unit and terminal unit, distributes electricity and controls and safeguards electrical equipment. When paired with an isolated switch and intelligent controller, the breaker's adaptability is further enhanced, smartly monitoring and controlling load current, over-load current, and short-circuit current within power systems.
