Product Description
Product Description
1)low noise; Low loss;
2)low partial discharge;
3)strong anti-short-circuit;
4)high impedance;
Features:
1. Low loss, and significantly energy-saving.
2. The core laminations are made up from high-quality cold-rolled grain-oriented silicon steel sheets
3. The regulating winding is a separate winding which apart from the high voltage main winding
4. The windings of one phase are assembled into an integral phase block before placing into the core.
5. Core frames in the form of a flat plate are used for clamping the core.
6. Transformer tanks are fabricated with steel plates wide enough so that there are no weld joints on each surface.
7. Diaphragm membrane is provided within the conservator, preventing direct contact of oil with air, protecting the oil from aging
8. Reliably sealed, and fine machined for sealed surface.
9. Quality assurance rules are also observed for all insulating parts, and main components.
OLTC Oil Immersed Power Transformer Products description:
The performance of our SZ series 220kV and 110kV load-ratio voltage transformer conform to the standard of GB 1094 "Power Transformer " and GB/T6451-2008 "Technical Parameter and requirements of Three-phase Oil-immersed Power Transformer". The iron core is made of quality cold rolled silicon steel sheet, and in full-miter non- puncture structure. The coil is made of quality oxygen-free copper, featuring good outlook and safe running. The products are widely used in power transmission and distribution of industrial and agricultural power networks.
OLTC Oil Immersed Power Transformer Main Functions And Features
Load-ratio voltage regulation, high reliability, advanced level of performance, reasonable economical indicators.
The core joints are of stepped shape with 3 steps, and the surface of this core is coated with cured paint to lower losses and noise.
The winding has novel structure and its oil passage is reasonable designed. Its newly designed insulation structure helps enhance its mechanical strength and the short circuit withstanding ability
The oil tank is in two types fully enclosed type and the type fitted with an oil conservator.
