Product Description
The 35kV series oil-immersed power transformers are relatively advanced in design and have 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. Strong anti-short circuit capability, beautiful appearance, reliable operation, low loss and low noise, reaching the advanced level of similar foreign products. The SZ11-8000/35 transformer prototype produced by our company passes the sudden short-circuit test conducted by the National Transformer Testing Center at one time. The high and low-voltage coils are provided with longitudinal oil passages to facilitate heat dissipation, which can greatly reduce the temperature difference between copper oil and the hottest temperature inside the coil.
