KYN28-33
33kV indoor metal armored withdrawable switchgear is an ultra-high voltage equipment designed specifically for overseas British standard areas and special industrial scenarios in China. It complies with GB/T 3906-2020, IEC 62271-200, and BS 1477 standards and is suitable for areas in Europe, the Middle East, Southeast Asia that use 33kV voltage levels, as well as special scenarios such as railway traction and large oil and gas fields in China. The equipment adopts a reinforced modular armor structure, optimized mechanical strength, multi standard compatibility, and traction load adaptability. It has the characteristics of strong anti-interference, high customization, and wide overseas adaptability, and can achieve safe distribution and control of electrical energy under cross standard and complex working conditions.
with the British standard (BS 1477) as the core, it is also compatible with national standards and IEC standards. It can customize 50Hz/60Hz frequencies, British installation dimensions, and local instrument configurations, and can adapt to mainstream 33kV regions such as Europe and the Middle East without additional modifications.
Customized traction protection modules and reinforced circuit breakers can withstand the impact loads and current fluctuations caused by frequent starting and stopping of railway traction locomotives. The mechanical strength is increased by 40% compared to conventional products, making it suitable for railway traction and industrial and mining mobile load scenarios.
Adopting a fully metal shielded cabinet and optimized wiring design, and installing electromagnetic filtering modules, it can effectively resist high-frequency electromagnetic interference generated by traction systems and industrial equipment, ensuring stable operation of equipment in strong interference environments.
equipped with multilingual operation interfaces and manuals in English, Chinese, and Western languages, intelligent modules supporting multilingual data feedback, manufacturers setting up accessory warehouses in core areas overseas, providing 24-hour bilingual technical support and on-site debugging services.
The rated current of the product is 800A-3150A, the short-circuit breaking capacity is 40kA-63kA, and the short-time withstand current is 25kA-50kA (3s); Support manual/electric integrated operating mechanism, with optional protection levels of IP4X and IP54, and customized anti salt spray version for coastal areas; Provide overseas certification certificates such as UL, CE, BS, etc., compatible with mainstream overseas brand instruments and control modules, and support personalized protection logic customization.

33kV is suitable for mainstream 33kV regions in Europe and the Middle East, with a focus on railway traction and large-scale industry, and higher parameter capacity; 11kV focuses on niche regions in Southeast Asia and Africa, with a particular emphasis on general industries. There are significant differences in voltage levels and target markets between the two.
Sure. The traction exclusive protection module can automatically adjust the protection threshold, withstand high-frequency impact loads, and the mechanical life of the circuit breaker is over 80000 times, fully adapting to the frequent starting and stopping conditions of railway traction locomotives.
Overseas parts warehousing covers core regions in Europe (Germany) and the Middle East (United Arab Emirates), enabling parts delivery within 48 hours. Remote areas support expedited air delivery, coupled with 24-hour bilingual technical support, to quickly respond to operational needs.
The all metal shielded cabinet and electromagnetic filtering module provide dual protection. The internal components are made of anti-interference materials, and the wiring is optimized to reduce interference conduction. This can effectively shield high-frequency electromagnetic signals, ensuring stable equipment parameters and no misoperation.
