Product Overview
The 100 kVA three phase oil immersed transformer is a fully sealed transformer. Compared with ordinary oil immersed transformers, it eliminates the oil conservator. Changes in oil volume are automatically adjusted and compensated by the elasticity of the corrugated sheets in the corrugated oil tank. The transformer is isolated from the air, preventing and slowing down oil deterioration and insulation aging, enhancing operational reliability, and requiring no maintenance during normal operation.
100 kVA three phase oil immersed transformer features an advanced design, with significant improvements in materials, structure, and manufacturing processes. The high and low voltage clamps utilize steel straps or upper and side beams for tension, forming a robust frame structure that enhances core clamping force and resistance to transportation impacts. It boasts strong short circuit withstand capability, an attractive appearance, reliable operation, low losses, and low noise, reaching the advanced level of similar international products.
