China Switchgear production Manufacturer, Supplier, Factory

This series of miniature circuit breakers consists of a plastic casing, overcurrent release, operating mechanism, contacts, and arc extinguishing system. The shell is made of high-strength and highly flame-retardant plastic. A multi-pole circuit breaker is assembled from multiple single poles, with the release connected by a linkage rod and the handle connected by a linkage cover, ensuring consistency in the on-off of each pole.

The SC(B) series epoxy resin dry-type transformer has been meticulously designed to prioritize safety. Its flame-retardant, fire-proof, and explosion-proof features ensure the highest level of safety. The encapsulated winding allows for direct installation in the load center, providing a maintenance-free and pollution-free solution. The scientific and rational design, in combination with the casting process, yields a product with lower partial discharge, reduced noise, and superior heat dissipation capacity. When equipped with forced air cooling, it can operate for extended periods under a 125% rated load.

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.

Dry type transformer 10KV 20KV 35KV are transformers that do not have their core and windings submerged in insulating oil. They are commonly utilized in various settings, such as local lighting, high-rise buildings, airports, docks, and CNC mechanical equipment.

The 35kV 35KV PV Pad mounted Transformer is a combination transformer used for wind or photovoltaic power generation, which integrates a step-up transformer, high-voltage current limiting fuse, load switch, low-voltage switchgear, and corresponding auxiliary equipment. The capacity range is 500-6800KVA, and the voltage level is 35kV and below. It is suitable for various types of onshore, pond, and offshore photovoltaic and wind power plants.

In recent years, the engineering construction industry has faced increasing complexity due to societal and economic growth, as well as rapid technological advancements. As a result, there is a growing demand for more compact switch equipment that requires less upkeep and possesses intelligent features. Both domestic and international manufacturers are actively developing the 35KV 630A Medium Voltage Inflatable Cabinet Gas Insulated Switchgear (C-GIS) for medium voltage applications, which encloses high-voltage components within a pressure-reduced shell, providing improved performance and reliability.
