Our 12KV 4000A indoor vcb lateral type vacuum circuit breaker is specifically designed for integration into switchgear systems, providing dependable and efficient safeguarding of electrical networks operating at a rated voltage of 12kV. Boasting a broad current range of 630A to 4000A, this versatile breaker is adaptable to a diverse array of industrial and commercial environments, making it an ideal solution for a wide spectrum of applications.

Product Overview This circuit breaker is a low-voltage protection device designed for AC 50/60Hz power distribution networks with rated voltages up to 400V and currents up to 63A, suitable for industrial, commercial, and residential electrical systems. It integrates comprehensive safety and operational safeguards: High-sensitivity Residual Current Detection (RCD) technology provides indirect contact protection to mitigate electric shock risks, while overload long-time delay protection and short-circuit instantaneous tripping ensure precise fault current interruption, preventing equipment damage and fire hazards. The device also supports infrequent circuit switching and intermittent motor start-stop operations, meeting flexible control demands in standard power distribution scenarios. Key Features & Applications Featuring a modular compact design compatible with global power standards, it is ideal for data centers, manufacturing facilities, and building distribution panels, particularly in environments requiring high power continuity and safety. The thermomagnetic dual-protection mechanism guarantees stable overload response and rapid short-circuit breaking, enhanced by 50/60Hz frequency compatibility for robust system reliability. With a durable construction and rail-mounted quick installation, it serves as a reliable solution for modern smart grids, balancing safety, efficiency, and ease of maintenance.

The KYN28-12(Z) 3.6KV 1600A MV medium voltage electrica lswitchgear is designed for 12kV rated voltage and 50Hz rated frequency in three-phase AC power systems. It is utilized for receiving and dispersing electric power, as well as managing, safeguarding, and overseeing circuits.

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 complex as society, the economy, and technology have advanced. There is a growing demand for compact switch equipment that requires minimal maintenance and is intelligent. Domestic and international switch manufacturing companies are actively developing the 35KV 3150A Medium Voltage Gas Insulated Electrical Switchgear, also known as gas-insulated switchgear (C-GIS), which encases high-voltage components like busbars, circuit breakers, isolating switches, and power cables within a pressure-reduced shell.

Outdoor transformer oil immersed transformer 10kv 20kv 35kv are a newer type of transformer that boasts a better-designed structure and improved performance. Its three core columns, arranged in an equilateral triangle shape, eliminate any air gaps in the magnetic circuit, resulting in tighter windings. The length of the three magnetic circuits is consistent and shorter, and the cross-sectional area of the core columns is closer to a circle. These design improvements lead to enhanced performance, reduced loss, decreased noise, and a better balance of the three components. Additionally, the third harmonic component is reduced. This transformer is well-suited for use in urban and rural areas, industrial and mining enterprise power grids, and is ideal for combination transformers and pre-installed substations.
