Product overview
Innovation-Driven Energy Efficiency Upgrading By integrating the research and application of new materials and new technologies, and adopting a model that combines independent innovation with technology introduction, we have carried out optimized and innovative designs on the iron core and coil structures. This has successfully achieved the goals of reducing no-load loss and noise, providing a new solution for improving the energy efficiency of power equipment.
Low Noise and Reaching Advanced Domestic Standards This transformer performs exceptionally well in noise control. Compared with the current national standard JB/T, its average noise level is reduced by 20%, creating a quieter environment for equipment operation. Meanwhile, the product's performance meets advanced domestic standards and demonstrates strong capabilities in balancing energy conservation and noise reduction.
Both Practicality and Adaptability This transformer features a concise and elegant overall design. Its heat sinks are arranged in an orderly manner, which can effectively ensure the equipment's heat dissipation performance; various wiring components on the top are reasonably laid out, facilitating installation and maintenance. With its excellent energy efficiency and low-noise characteristics, it can be widely adapted to power application scenarios that have certain requirements for energy conservation and noise reduction, helping the power system operate stably and efficiently.
Design features
What the design is built around
Low-loss magnetic core
Cold-rolled grain-oriented silicon steel and a stepped core reduce no-load loss and audible noise.
Sealed tank construction
Welded tank, quality-gasketed cover and pressure-tested seals reduce oil leakage risk in outdoor duty.
Thermal margin for hot climates
Cooling surfaces and oil volume are selected for high ambient temperature and cyclic loading.
System compatibility
MV terminals, cable boxes and LV bushings are matched to the switchgear and protection scheme.
