Stay updated with Dongfa Intelligent’s latest company news, industry trends, and product information related to high voltage electrical equipment and power distribution solutions.
Low voltage electrical equipment covers air circuit breakers, molded case circuit breakers, miniature circuit breakers and surge protective devices. Intelligent air circuit breakers offer measurement and communication functions, while new energy high voltage models are designed for direct current and high voltage scenarios with specific arc extinguishing and insulation. Compact and high current fixed air circuit breakers suit cabinets with limited space or concentrated loads.
Disconnect switches and earthing switches are important components for ensuring maintenance safety in distribution systems. Indoor disconnect switches cover 12kV, 24kV and 40.5kV levels, mainly with a rated current of 630A. Some models include an earthing switch, allowing isolation and earthing to be completed in one operating sequence. High altitude disconnect switches are adjusted in terms of insulation distance and materials for low pressure and large temperature differences, suitable for higher elevation areas.
Outdoor pole-mounted vacuum circuit breakers are widely used in distribution network upgrades, with products available at 12kV, 24kV and 40.5kV levels. Pole-mounted installation suits the layout of overhead lines and removes the need for an indoor distribution room, lowering overall project investment. Permanent magnet pole-mounted breakers use fewer moving parts and maintain stable switching performance under outdoor temperature and humidity variations.
Indoor vacuum circuit breakers now cover multiple voltage classes including 12kV, 24kV and 40.5kV, meeting the needs of different distribution scenarios. The 12kV indoor series includes permanent magnet operating, embedded pole and side-mounted structures. The embedded pole design integrates the vacuum interrupter with insulating material, helping reduce size and improve environmental adaptability. The 24kV and 40.5kV indoor high voltage models serve higher voltage substations and industrial distribution systems.
