Indoor Vacuum Load Switch
SanGao Indoor Vacuum Load Switch is designed specifically for medium voltage distribution networks and is widely used in indoor switchgear systems for power stations, substations, and industrial facilities. The device uses a vacuum arc extinguishing chamber as the core component to ensure arc extinguishing under load conditions, thereby improving safety and extending equipment life. The switch has a compact structure, fast operation, long electrical and mechanical life, and is suitable for frequent operating environments.

Load Breaking Switch
SanGao high quality Load Breaking Switch, a load switch, also known as a load switch, is an electrical switchgear used in power systems to disconnect and connect load currents. It is mainly used in medium voltage distribution systems (typically 3.6kV~40.5kV). Load switches usually have a certain ability to interrupt load current, but cannot interrupt short-circuit current. They are usually used in conjunction with protective devices such as fuses or vacuum circuit breakers.

AC Load Breaker Switch
The SanGao High Quality AC Load Breaker Switch uses a vacuum arc extinguishing chamber. Its characteristics are reliable operation, long electrical life, easy maintenance, and the ability to frequently connect and disconnect power supply. The operating mechanism is located inside the switchgear and integrates the isolation switch, load switch, and grounding switch. It is compact in size and lightweight. As the name suggests, if any dangerous abnormal current, voltage, or temperature is detected in the circuit, the circuit breaker will disconnect the circuit and stop the current.

Three-Phase Circuit Breakers
The Three-Phase Circuit Breakers module implements a SanGao high quality Three Phase Circuit Breaker, whose opening and closing times can be controlled through external signals (external control mode) or internal control timers (internal control mode). The control signal connected to Simulink input must be 0 to open the circuit breaker, or any positive value to close the circuit breaker.

Outdoor Boundary Vacuum Circuit Breaker
SanGao High Quality Outdoor Boundary Vacuum Circuit Breaker is an outdoor power distribution device with a rated voltage of 12KV and three-phase AC 50Hz. When the internal fault of the user occurs in the T-shaped connection of the 12KV distribution line, or although it occurs inside the user's incoming switch, the protection action time limit and improper protection of the substation's outgoing switch can cause the outgoing protection of the substation to disconnect.
