S□ series 35 kV/SZ□ series 35 kV no-load voltage regulation oil-immersed transformers
Description
● Product introduction
The performance 35 kv series non-excitation voltage regulation energy-saving power transformers can meet GB/1094.1 Power Transformers and GB20052-2020 Minimum Allowable Values of Energy Efficiency and the Energy Efficiency Grades for Power Transformers. The windings are made of excellent oxygen-free copper, which is good in appearance. Its reliability is high, its performance is excellent, and its economic indexes are reasonable. The iron core adopts step-shaped three or five-level joints, and the surface is coated with curing paint to reduce loss and noise. The winding’s structure is novel, the oil duct is designed reasonably, and a new insulating structure is adopted to improve the mechanical intensity and the short circuit resistant capability. It has the remote monitoring function and can grasp the running status of equipment in real time.
