35kV Oil immersed power transformer

SUMMARY

This series of products is relatively advanced in design, and has been greatly improved and improved in materials, structures and processes. The high and low pressure clamps are tensioned by steel straps or upper beams and side beams to form a strong frame structure that enhances the core clamping force and the ability to withstand transport shocks. It has strong anti-short circuit capability, beautiful appearance selection, reliable operation, low loss and low noise, reaching the advanced level of similar foreign products.
