China Medium voltage converter Manufacturer, Supplier, Factory

The advancement of society, economy, and technology has led to increased complexity in engineering construction. There is a growing demand for compact, low-maintenance, and intelligent switch products. Both domestic and foreign switch manufacturers are actively developing 12KV 1600A Medium Voltage Gas Insulated Electrical Switchgear (C-GIS), also known as gas-insulated switchgear. Gas-insulated switchgear refers to the encapsulation of high-voltage components, such as busbars, circuit breakers, isolating switches, and power cables, within a shell that maintains a lower gas pressure.

126KV Outdoor high-voltage SF6 circuit breaker is a high-voltage, three-phase AC 50Hz switchgear designed for outdoor use, ideal for controlling and protecting 126kV transmission and transformation systems. Additionally, it can function as a contact breaker and opener group. This circuit breaker utilizes an intelligent arc extinguishing principle that combines thermal expansion with auxiliary blowing, and features a CTB-1 operating mechanism. It meets the standards outlined in GB1984-2003 for AC high-voltage circuit breakers and is compliant with the International Electrotechnical Commission's IEC62271-100:2001 standard for high-voltage AC circuit breakers and control equipment.

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.

The Drawer type low-voltage switchgear ensures that each functional unit is distinct from the busbar or cable, creating three separate areas for efficient power distribution. This design also incorporates isolation measures between functional units, contributing to the overall reliability and safety of the switchgear. As a result, drawer-type switchgear is widely used in industrial and mining enterprises, high-rise buildings, and centralized control distribution centers that require high power supply reliability. The switchgear's closed steel plate shell houses withdrawable drawers containing electrical components for incoming and outgoing circuits, allowing for easy maintenance and customization.

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.

This product is designed for 50Hz AC power distribution networks with a rated operational voltage of 380V and a rated current up to 630A. It provides reliable indirect contact protection for personnel and effectively prevents fire hazards caused by ground fault currents resulting from equipment insulation failures. The device incorporates multiple protection mechanisms to deliver precise overload and short-circuit protection for power distribution lines and supply equipment, while featuring circuit status monitoring capabilities. Under normal operating conditions, it can serve as an infrequent switching device for distribution circuits and provide occasional motor starting control functionality. The integrated design combines electrical safety protection with equipment management requirements, significantly enhancing the operational reliability of power distribution systems and fire prevention capabilities.
