The HUAJIDIAN 40.5kV Motorized Drop-out Fuse is an intelligent, high-performance protection device adapted for 40.5kV outdoor high-voltage power distribution networks. Breaking through the operational limitations of traditional manual fuses, it features a 12V/24V DC electric operating mechanism, enabling remote control and automatic tripping in case of faults. With a rated voltage of 40.5kV, a rated current of 200A, and a short-circuit breaking current of 16kA, it reliably provides overcurrent and short-circuit protection. Utilizing a rubber insulation structure and optimized mechanical design, the product can operate stably in harsh outdoor environments such as low temperatures and icing conditions.

The HUAJIDIAN Load Break Porcelain Motorized Drop-out Fuse is a new generation of distribution protection product upgraded from traditional porcelain drop-out fuses. It abandons the traditional fragile porcelain insulation structure, adopts composite silicone rubber insulators, and optimizes the arc-extinguishing and mechanical structure, offering advantages such as lightweight, corrosion resistance, high and low temperature resistance, and low maintenance costs. As a self-developed product from a leading domestic power equipment manufacturer, this equipment is widely used in the protection of 10kV distribution networks in urban and rural areas of China, rural power grid upgrades, industrial parks, and lines and pole-mounted transformers in high-pollution and high-altitude areas.

HUAJIDIAN, a professional manufacturer of power transmission and distribution equipment, focuses on the research and development and production of 12kV Load Break Silicone Motorized Drop-out Fuse. The products strictly adhere to IEC and GB domestic and international standards, are manufactured using precision in its own standardized factory, and employ a high-strength ceramic insulation structure. They offer advantages such as rapid fault breaking, visible tripping, strong weather resistance, and easy maintenance, and are widely used for overload and short-circuit protection of 10kV distribution lines, distribution transformers, capacitor banks, and cable branch boxes.

The HUAJIDIAN Porcelain Motorized Drop-out Fuse is a professional overcurrent protection device specifically developed for 10kV overhead distribution lines and pole-mounted distribution transformers. The product integrates a gravity spring drop-out structure, high-strength porcelain insulation, and gas-generating arc-extinguishing technology, enabling rapid response to line overload and short-circuit faults. After the fuse melts, a visible break point is formed, achieving fault isolation and safe maintenance protection. Relying on its own standardized factory mass production system, product quality is stable and reliable. As a professional supplier, HUAJIDIAN can provide standardized products, customized solutions, and one-stop technical services.

The HUAJIDIAN 24kV Earthing Switch is a new generation of isolation equipment designed specifically for 10kV pole-mounted distribution networks by a professional manufacturer located in China. The equipment integrates an electric operating mechanism, insulation protection, and mechanical transmission, supporting remote/local dual-mode opening and closing, and possesses functions for safety isolation, line maintenance, and intelligent operation and maintenance. The entire unit adopts large creepage distance composite insulators, silver-plated copper conductive circuits, and a lightweight modular structure, making it suitable for scenarios such as heavily polluted, high-altitude, unattended rural power grids, industrial parks, and new energy grid integration.

The HUAJIDIAN DGDW1 series Earthing Switch for Switchgear is a high-performance electrically operated grounding and isolating device adapted to 12kV medium-voltage power distribution networks. As a professional power equipment manufacturer in China, HUAJIDIAN possesses legal production and operation qualifications, and its products fully comply with domestic power equipment manufacturing compliance standards. This product has a rated voltage of 12kV, a rated current of 630A, and a rated short-time withstand current of 25kA. It supports electric operation, has Class IV anti-pollution capability, and an ultra-wide operating temperature range of -30℃ to 70℃. It boasts excellent insulation performance and strong environmental adaptability, providing safe, stable, and low-maintenance power distribution grounding isolation protection for smart grids, outdoor substations, overhead lines, and complex industrial power scenarios.
