33 kv Three Phase Power Transformer Oil Transformer Electrical Transformer
Product Description
Independent 35KV oil immersed power transformer is advanced in designing, make great improvement on the material and structure. High and low voltage clamp with steel belt or and side beam taut, form a strong frame structure, strengthen the core clamping force and tolerance transportation capacity. High and low volatage coil set longitudinal oil way is good for heat dissipation, can greatly reduce the copper oil temperature difference and the hot spot temperature rise within the coil. Anti-short circuit ability is strong, beautiful appearance, reliable operation, low loss, low noise, reach the advanced level of the same products abroad.
The performances of our SZ-M series, SZ series 10KV and 35KV load-ratio voltage transformer conform to the standard of IEC. The iron core is made of quality cold-rolled silicon steel sheet, and in full-miter nonpuncture structure. The products are widely used in power transmission and distribution of industrial and agricultural power networks.
Main Functions And Features
Load-ratio voltage regulation, high reliability, advanced level of performances, reasonable economical indicators.
The core joints are of stepped shape with 3 steps, and the surface of the core is coated with cured paint to lower losees and noise.
The winding has novel structure and its oil passage is reasonable designed. Its newly designed insulation structure helps enhance its mechancial stength and the short circuit withstanding ability.
The oil tank is in two types-fully enclosed type and the type fitted with an oil conservator.
All production and manufacture procedures are under strict control, and all process, tests, ex-work tests are computer-operated.
