Part Ⅰ: 330kV Power Transformer Overview
330kV series oil-immersed power transformers adopt advanced calculation software to accurately calculate the ampere-turn balance, various stresses, temperature rise, and insulation distance; accurately analyze the electromagnetic field, magnetic flux leakage, and wave processes; use plane and three-dimensional dynamic model simulation design to ensure reliable product performance, The structure is reasonable.
330kV power transformers are mainly made of iron core and windings, which are placed in the oil tank that filled with insulating oil. It is mainly used for power plant, power transmission and distribution station as the equipment of power transmission.

Part Ⅱ: Product Features
1. High Reliability:
Short circuit strength: through the analysis of leakage magnetic field of transformer, the electromagnetic force can be well controlled in the structure design, and together with equipment and suitable materials, the requirement of short circuit strength can be sufficiently satisfied. Our design method has been testified through short circuit test on products at different voltage levels, which also testifies that our products have enough strength against short circuit.
2. Low power loss and low operation cost
The transformer has relatively low losses through the optimized design, the detailed analysis of leakage magnetic field and the losses distribution. The maintenance cost has been lowered through the Customer-oriented design.
3. Customer-oriented Design
Based on the 3D design method to simulate feeders, operation filed and terminal box arrangement are in full consideration of operating conveniences, which meets the requirements on cost lowering and customization, as well.
Part Ⅲ: Structural Feature
1. Iron Core
Iron core with fixed clamps optimizes the design so as to ensure mechanical strength and to reduce leakage losses.
2. Winding
① HV winding adopts entanglement or inner screened continuous type with phase insulation structure to ensure insulating strength.
② MV/LV windings adopt high strength or adhibit-transpostion conductor, reinforced cooling to reduce the temperature rise and enhance capability of short circuit withstand.
3. Active-parts Assembly
① Cold pressing ensures cleanness of the body active parts and the reliability of leads.
② Adoption of whole assembled phase insulation so as to reduce the assembly time and effectively guarantee the dimension and shape of the insulation structure.
③ HV lead adopts specially molded insulation parts for protection which effectively guarantees its insulating strength and reduces partial discharge.
4. Oil Tank
Adopting of welding automatic submerged arc-welding and ultrasonic of fluorescence leakage test to guarantee leakage -free The surface coating is strictly controlled.
5. Assembly and Routine Test
After assembly, strict pre-delivery test according to standard, with exquisite testing technique and equipments to provide high quality and reliable product.
