2. Product Features
2.1 Low loss
Electrical calculation by sophisticated computer programs, combine electrical shielding and magnetic circuit technology.
The core is made of cold rolled, grain orientation high magnetic silicon steel, to reduce the load loss and no-load current.
2.2 Low partial discharge
HV lead adopts specially molded insulation parts which effectively ensure the insulation strength and reduces partial discharge.
2.3 High strength
The tank can withstand the vacuum test and positive pressure test.
Omni directional location between the core and the tank to guarantee the horizontal position during transportation and operation.
2.4 Low Noise
The step lapped joints of the core laminations reduce the additional losses arising in the corner portions, reduce the load current and electromagnetic noise.
Reduce of the flux density and increase the shock absorbing measures at design to reduce the noise.
2.5 Maintenance-free
Adopts the bell type tank and the international leading technology, ensure 30 years durability,and maintenance-free operation.
3. Structure
3.1 Iron core
The iron core is made of cold rolled grain oriented silicon steel sheet. Laminations are cut to length on GEORG cut-to- length line with step-lap cut and automatic stacking functions. The multi-step lamination structure can reduce the loss and noise .The steel sheet in the core limbs and yokes are clamped together by glass-epoxy bonds.
3.2 Winding
High quality enameled or paper covered copper is used as conductor, the winding was made as drum type, spiral type, improved spiral type, continuous type and interleaved type to ensure the insulation strength. Standard tapings are ±2*2.5%of the HV winding.
3.3 Tank
The tank, cover and the conservator are made by corrugated steel plate. For the small transformers, we use a deep tank and a cover, but for larger transformers, we manufacture bell type .The corrugated construction are an effective way for oil cooling.
- Insulation oil
The tanks are filled with high quality grade mineral oil as per IEC296 and it is PCB and PCT free. The oil is used to help cooling the transformer. It is also used provide part of the electrical insulation between internal live parts.
Insulation oil
3.5 Tap changer
Tap changers are used to regulate the output voltage of the transformers to required levels .We achieve this by changing the ratios of the transformer on the system by altering the number of turns in the HV winding .Tap changers are on load (OLTC).
