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

In recent years, engineering construction has become increasingly intricate due to the growth of society, the economy, and technology. There is a rising trend towards smaller, smarter switch equipment that demands minimal maintenance. Manufacturers, both local and global, are focusing on the development of the 40.5kv 2000A High Voltage Sf6 Gas Insulated Switchgear, also referred to as gas-insulated switchgear (C-GIS). These switchgears house high-voltage elements like busbars, circuit breakers, isolating switches, and power cables within a protective shell with reduced gas pressure.

HXGN-12 switchgear Modular AC metal enclosed Ring main unit RMU is a high-voltage AC complete set designed for a three-phase AC ring network, terminal distribution network, and industrial electrical equipment. It is suitable for power distribution and protection and can be installed in substations. It complies with national standards GB3906 and IEC60298, as well as DL/T402 and DL/T404 standards, and meets the requirements of "five-proof" blocking.

The 12KV 1250AMP Vertical break two post isolating switch is specifically designed for use in 10(12,15,24)KV high voltage transmission and distribution lines. These switches serve the purpose of disconnecting and connecting single-phase or three-phase circuits without load and voltage. They are particularly engineered for single-phase application within a three-phase circuit system and are characterized by a simple and cost-effective design, ensuring ease of operation and maintenance. The switches are available in a range of rated current options, including 200400,600,630,800, and 1000,1250 amperes, providing the flexibility to select the most suitable option based on specific requirements. They are comprised of a base, pillar insulator, conductive part, and mechanism part.

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.

40.5KV 4000A Double-break three post disconnector is designed to enhance the efficiency of indoor stations by reducing the distance and station arrangement. Its robust motor performance resistance is achieved through the electric rod's self-rotation and switching structure, along with its self-locking function. This disconnector is capable of withstanding motor, wind pressure, earthquake, and other external forces. Additionally, its sliding rotation method ensures a strong self-clean ability.
