KYN28-11
11kV indoor metal armored withdrawable switchgear is a medium voltage distribution equipment designed specifically for overseas specific areas and some domestic special industrial scenarios. It complies with GB/T 3906-2020, IEC 62271-200, and BS 1477 standards and is suitable for 11kV voltage level distribution scenarios in some countries in Europe, the Middle East, Southeast Asia, as well as domestic mining, railway, and other areas. The equipment adopts a reinforced modular armor structure, optimized mechanical strength and multi standard electrical compatibility design, with strong anti-interference ability, high degree of customization, and wide environmental adaptability. It can achieve safe distribution and control of electrical energy in complex working conditions and cross standard distribution systems.
It meets the requirements of national standards, IEC, and British standards (BS 1477), and can customize voltage standards, frequencies, wiring methods, and instrument configurations according to the target region. It supports British installation sizes and is suitable for regions such as Europe and the Middle East that use 11kV voltage levels. It can be implemented without additional modifications.
The cabinet adopts thickened cold-rolled steel plates and an integrated frame design, which increases the mechanical strength by 30% compared to conventional products. It can withstand complex working conditions such as railway vibration, mining impact, and ship turbulence, and has excellent electromagnetic shielding performance to reduce the impact of external electromagnetic interference on equipment operation.
Protection logic can be customized according to scene requirements, supporting multiple protection modes such as overcurrent, overvoltage, undervoltage, differential protection, etc., adapted to the start stop characteristics of special loads such as railway traction and mining machinery, to avoid equipment failures caused by load impact.
The cabinet surface adopts multi-layer anti-corrosion spraying technology, and the internal components are made of temperature resistant, moisture resistant, and dust resistant materials. It can operate stably in extreme temperatures ranging from -30 ℃ to 50 ℃, relative humidity ≤ 95% (condensation environment), and high dust and high salt spray scenarios, with environmental adaptability covering most harsh working conditions.
Equipped with a bilingual operation interface and manual in both Chinese and English, the intelligent module supports multilingual data feedback, and local language services can be customized according to overseas project needs. At the same time, overseas on-site installation, debugging, and operation and maintenance training are provided to reduce the difficulty of overseas project operation and maintenance.
The rated current range 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, which can achieve local and remote control; The protection level can be selected from IP4X and IP54, and the explosion-proof type (Ex d IIC T4) can be customized for special scenarios; Provide overseas certification certificates such as UL, CE, BS, etc. to meet the market access requirements of the target region.
Providing you with the most trusted energy solutions in an unpredictable world.

The core difference lies in the voltage level and adaptation area: the 11kV model is suitable for mainstream 11kV areas such as Europe and the Middle East, compatible with British standards, and focuses on railway and industrial scenarios; The 6.6kV model is suitable for some regions in Southeast Asia and Africa, with a focus on mining and shipping scenarios. The target markets and scenarios for the two are different.
Sure. By customizing specialized protection modules and reinforced circuit breakers for traction loads, the equipment can withstand frequent start stop shocks and current fluctuations of railway traction loads, while also having fast breaking capabilities to avoid the impact of traction load failures on the distribution system.
The manufacturer has spare parts storage centers in key overseas areas, which can quickly respond to spare parts needs; Provide 24-hour bilingual technical support, overseas projects can be equipped with on-site technical personnel, free parts replacement and maintenance services during the warranty period, and lifetime supply of original parts after the warranty period.
The equipment is equipped with a cabinet dehumidification device and an insulation monitoring module, which can automatically detect the humidity inside the cabinet and start dehumidification. At the same time, it can monitor the insulation status in real time. When the humidity exceeds the standard or the insulation performance decreases, it will automatically alarm to avoid insulation failure caused by condensation.
Support. Instruments and control modules can be customized according to customer specified brands and models, compatible with mainstream overseas brand equipment. At the same time, module programs can be optimized according to project specific control logic to meet personalized power distribution needs.
