In recent years, the engineering construction landscape has evolved in response to societal, economic, and technological advancements. There is an increasing demand for compact, intelligent, and low-maintenance switch equipment. Domestic and international manufacturers are actively developing 40.5KV 3150A Medium Voltage Gis Gas Insulated Switchgear (C-GIS), which enclose high-voltage components like busbars, circuit breakers, isolating switches, and power cables within a pressure-reduced shell.

The 145KV 3150A Centre-break two post disconnector GW4 disconnector's conductive tube boasts a distinctive aluminum profile structure that enhances heat dissipation and fluid flow. This design minimizes the impact of the skin effect, allowing for. The tube's unique design makes it suitable for specific applications. Our product features state-of-the-art silver dedication to quality. This technology improves the adhesion of the silver plating layer, ensuring it meets standards. With appropriate contact pressure, the wear resistance of the contacts is improved, ensuring the silver plating layer remains intact even after extended use, providing long-term peace of mind. The soft connection, made of copper, features a silver-plated conductive contact surface, ensuring excellent conductivity and strong fluid capacity.

The GW5 outdoor isolation switch is a high-voltage electrical device designed to meet specific structural requirements. It consists of three independent single-phase isolation switches, making it a versatile and reliable option for various applications. The device complies with the standards outlined in the JB520-64 "AC High Voltage Isolation Switch" and features an additional grounding knife device for added safety. The CS-G manual operating mechanism is available in three variations: ungrounded, single-grounded, and double-grounded, providing users with options to suit their needs.

The KYN28-12(Z) AC metal-clad switchgear 12KV 1250A Customized Medium Voltage Electrical Switchgear is designed for use in three-phase AC power systems operating at a rated voltage of 12kV and a rated frequency of 50Hz. This equipment is utilized for receiving and distributing electric power, as well as for controlling, protecting, and monitoring electrical circuits.

12KV Indoor Medium Voltage Vacuum Circuit Breaker is a high-voltage solution for indoor applications, featuring a rated voltage of 12KV and a frequency of 50Hz for three-phase AC systems. This product, known for its reliability, complies with the GB1984-89 standard. The design of this product is available in two configurations: the switch body and operating mechanism are integrated, and a modular version where the switch body and operating mechanism are separate. The integrated design is denoted as the ZN28-12 type, while the modular design is referred to as the-12 type, suitable for use in fixed switches such as GG-1A(Z) and XGN2A10(Z). This product can be paired with DC electromagnetic types CD17 and CD10A, as well as spring energy storage types CT17 and CT19.

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
