Distribution oil-immersed transformers have clear safety technical requirements based on their installation methods (column-mounted, indoor, ground-mounted), focusing on distance control, grounding, protection, and warning signs to ensure personnel and equipment…
Read moreThe iron core of an oil-immersed transformer is a core component that serves as both a magnetic conduction path and structural skeleton. It must be single-point grounded to ensure safe operation—multi-point grounding…
Read moreThe windings of common oil-immersed transformers are mainly made of copper and aluminum, with a small number of copper-aluminum hybrid windings. Copper windings have better electrical performance but higher cost, while aluminum windings…
Read moreOil-immersed transformer failures are mainly driven by eight key factors, with line inflow (disturbance) as the primary cause, followed by insulation degradation, insufficient maintenance, and overload. Most failures are avoidable…
Read moreOil-immersed transformer core poor grounding (mostly multi-point grounding) poses risks of core overheating, insulating oil decomposition, and equipment damage. CHH Power adopts standardized detection methods and targeted handling measures—divided into non-stop temporary…
