Oil-immersed transformer installation and design must strictly comply with electrical specifications, implement safety protection measures, and establish a sound management system to ensure safe and reliable operation. Below is a…
Read moreDistribution 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…
