XuJu Electric Technology Co., Ltd., a professional manufacturer focusing on industrial electrical equipment and power distribution components, officially releases its upgraded HD13 series open-type single-throw knife switch, a core low-voltage electrical product tailored for high-current and safe power control scenarios. Compliant with GB/T 14048.3—2017 and IEC 60947-3 international and national standards, the new product fills the demand gap for reliable isolation and circuit switching in medium and high-current low-voltage power distribution systems, further enriching the company’s industrial electrical product portfolio.
The HD13 series knife switch adopts a mature central front lever operating mechanism, uniquely designed for front operation and rear maintenanceSwitchgear cabinets. Differentiated from HD11, HD12 and HD14 series knife switches with diverse operation modes, this series supports both manual and motor-operated types with manual backup function, covering a conventional thermal current range from 100A to 4000A and adapting to AC 50Hz working conditions with rated voltages up to 690V and DC rated voltages up to 230V. It is specially optimized for high-current control scenarios with rated current ranging from 3000A to 6000A, delivering outstanding compatibility and operational flexibility.
Featuring exquisite structural design and superior electrical performance, the product adopts graded blade configurations including single blade, double blades and parallel double blades for different current specifications. All conductive components undergo tin-plating treatment to reduce contact resistance, while equipped with high-efficiency arc extinguishing chambers composed of phenolic laminated paper boards and metal arc grids. With reliable electromagnetic locking performance, the switch maintains excellent electrodynamic stability during grid short-circuit faults, ensuring safe infrequent load circuit making and breaking and professional electrical isolation. Its unified transmission mechanism and standardized vertical mounting dimensions greatly simplify the assembly and design of power distribution equipment, perfectly docking with Intelligent Power Distribution System construction requirements.
Widely applicable to industrial and agricultural fields such as metallurgy, chemical industry, metro, machinery and water conservancy, the HD13 series knife switch serves as a key supporting component for Industrial Automation Solutions. It can form a complete safe power control system with Vacuum Circuit Breaker and Transformer Automation Equipment, realizing stable power isolation and circuit switching for supporting Transformer and low-voltage distribution cabinet equipment. Under standardized service conditions with altitude below 2000 meters and ambient temperature from -5℃ to +40℃, the product achieves long mechanical service life and excellent short-time withstand current performance, providing durable and reliable protection for industrial low-voltage power distribution operation.
Insiders stated that the launch of HD13 series knife switch strengthens XuJu Electric Technology Co., Ltd.’s competitiveness in the low-voltage electrical equipment market. The company will continue to focus on technological innovation, providing high-quality, standard-compliant electrical components for global industrial power distribution and automation industries.
