Technical RequirementsRated Voltage:The primary rated voltages include 3kV, 6kV, 10kV, and 35kV, among others. The secondary v

Maintenance-Free Moisture Absorption Technology for Oil-Immersed TransformersIn traditional oil-filled transformers, the temperature control system causes thermal expansion and contraction of insulating oil, requiring the sealing gel chamber to absorb significant moisture from the air above the oil surface. The frequency of manual silica gel replacement during patrols directly impacts equipment safety—delayed replacement can easily lead to oil degradation. Maintenance-free moisture absorbers rev

Medium-voltage DC (MVDC) transformers have a wide range of applications in modern industry and power systems. The following are some key application areas for MVDC transformers: Power Systems: MVDC transformers are commonly used in high-voltage direct current (HVDC) transmission systems to convert high-voltage AC into medium-voltage DC, enabling efficient long-distance power transmission. They also contribute to grid stability control and power quality improvement. Industrial Applications: In in
