China Circuit breaker for high voltage Manufacturer, Supplier, Factory

The KXAIS-12 series Solid Insulated Ring Main Unit Rmu Electrical Switchgear is a fully insulated, fully sealed, and anti condensation ring main unit equipment that is based on solid sealing and vacuum insulation technology, and is independently developed using epoxy resin (APG process) to pour the three position switch (isolation, grounding), circuit breaker vacuum arc extinguishing chamber, and main circuit primary conductive components together to form the insulation component body. It is assembled from insulated busbars and other insulation connectors to form a fully insulated, fully sealed, and anti condensation ring main unit.

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 KYN28-12(Z) 3.6KV 630A Medium Voltage Electrical Switchgear is designed for 12kV rated voltage and 50Hz rated frequency in three-phase AC power systems. It functions to handle electric energy reception and distribution, as well as to control, protect, and monitor circuits.

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.

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.

The KYN28-12(Z) 7.2KV 1600A High Current Power Distribution Cabinet Switchgear is designed for 12kV rated voltage and 50Hz rated frequency in three-phase AC power systems. This equipment is utilized to manage the reception, distribution, control, protection, and monitoring of electrical circuits.
