Core Advantages: Natural Air Circulation Technology

 

  • Kechang Electric has recently rolled out a full range of air-cooled transformers, mainly tailored to industrial, commercial and public utility scenarios where stable and secure power supply is a top priority.
  • The R&D and design work of Kechang Electric centers on balancing three core demands: stable and reliable operation, convenient daily maintenance, and reduced long-term operational costs, with each aspect taken into full consideration to meet practical application needs.

 

Superior Construction & Heat Dissipation Performance

Distribution Dry Type Transformers

  • Different from traditional liquid-cooled and oil-immersed transformer solutions, the newly launched air-cooled products adopt natural air cooling mode, which dispenses with cooling oil and the corresponding circulation systems entirely. This not only simplifies on-site installation procedures significantly, but also fundamentally avoids potential risks such as oil leakage, oil aging-induced performance degradation and fire hazards caused by oil-related faults.
  • In actual operation and management, these transformers are easier to maintain and manage daily, helping cut down potential operational risks effectively; such advantages are more prominent in projects with insufficient operation and maintenance manpower and material resources, as well as those imposing strict safety thresholds.

Non Oil Transformers

  • Without oil as the cooling medium, this series of air-cooled transformers show unique applicability in areas with scarce water resources and strict environmental protection requirements.
  • Traditional liquid-cooled systems usually face bottlenecks like complicated maintenance processes and high overall operation costs in such scenarios, while air-cooled solutions stand out for higher on-site feasibility and better long-term economic benefits, which can better match the long-term operation needs of relevant projects.
  • In terms of application coverage, Kechang Electric offers diversified configurations of voltage and capacity for this transformer series, covering the 10kV–35kV range that meets mainstream application demands. It is widely applicable to various scenarios including industrial plants, commercial buildings, new energy projects and rural power distribution networks, adapting to different power supply system structures of various projects.
  • For special working conditions like limited installation space, high air humidity and heavy dust, the company's engineering team will formulate targeted structural optimization and insulation improvement schemes based on specific site conditions, instead of applying uniform and generalized design schemes mechanically.
