The trade landscape between China and the Russian Federation in electrical power equipment has undergone a structural transformation. As Russian industrial enterprises accelerate capital equipment overhaul across the Ural Mining Belt, Western Siberia, and the Far Eastern Federal District, direct procurement of Chinese industrial voltage transformers and heavy current rectifier transformers has emerged as the baseline standard for operational continuity.
With the intensification of regional industrial modernization, Russian procurement engineers are prioritizing high-voltage step-down transformers, phase-shifting rectifier units, and traction power transformers that comply strictly with GOST 11677-85 (Power Transformers - General Specifications) and GOST 52719-2007 while possessing official EAC Declaration/Certification under TR CU 004/2011 (On Safety of Low Voltage Equipment) and TR CU 020/2011 (Electromagnetic Compatibility).
Our enterprise stands at the forefront of this trade corridor. Established in 2007, our manufacturing footprint covers specialized high-current thyristor rectifiers, oil-immersed power transformers up to 10 MVA at 33kV, and cast resin dry-type traction transformers engineered specifically to withstand severe voltage fluctuations and extreme climatic stresses encountered across Russian regional power grids.
Operating heavy electrical apparatus in Russian industrial sectors demands engineering solutions far exceeding standard tropicalized or temperate IEC transformer configurations. Standard transformer oil hardens at sub-zero thresholds, leading to insulation breakdown, core overheating, and catastrophic dielectric failure during cold-start energization.
Our Russian-export series voltage transformers utilize 09G2S low-alloy structural steel for external tanks, radiators, and structural frames. This specialized steel grade prevents cold shortness and brittle fracture at ambient temperatures down to -60°C. Furthermore, we equip oil-immersed transformers with low-pour-point synthetic transformer oils (pour point ≤ -65°C, dielectric breakdown strength ≥ 70 kV) and fluorosilicone seals (FVMQ) that retain elasticity despite severe thermal cycling.
Heavy industrial electroplating plants in Chelyabinsk and metallurgical reduction facilities require massive DC current with minimal Total Harmonic Distortion (THD). Simple 6-pulse bridge rectifiers inject severe 5th and 7th order harmonics back into the supply grid, triggering line voltage imbalance and penalty tariffs from grid operators such as PJSC Rosseti.
Our industrial rectifier transformers employ 12-pulse and 24-pulse phase-shifting secondary windings (incorporating ±15° and ±7.5° phase displacement via delta-extended star connections). Combined with integrated interphase transformers (IPT), these units cancel low-order harmonics internally, delivering direct current with ripple factors below 1.5% while elevating input power factor to ≥ 0.95 without external filter banks.
Engineered to deliver uninterrupted duty across Russia's vast geographic and industrial landscapes.
In high-volume surface treatment facilities in Yekaterinburg and Chelyabinsk, our YUCOO 1000A-5000A plating rectifiers deliver continuous DC current for hard chrome, zinc, and nickel plating under 24/7 duty cycles.

CEEG ZQSC(H)B Series 2000kVA/10kV cast resin dry-type transformers are deployed in underground traction substations, providing high dielectric safety, zero toxic gas emission, and Class H thermal endurance.
Remote pipeline monitoring stations across Western Siberia rely on single-phase and 3-phase oil-sealed cathodic protection transformers to mitigate galvanic corrosion on steel gas mains buried in continuous permafrost.
Original T6 TI16933 excitation transformers are integrated into turbine generation systems across East Siberian power plants to maintain rapid excitation voltage stability under sudden load surges.
