    Cooper Winding, Step Down 500KV High Voltage Power Transformers

    Cooper Winding, Step Down 500KV High Voltage Power Transformers

    Quick Detail:

    1.Low loss, low noise

    2.long usage year warranty period

    Product Standard for 500kv extra high voltage transformer:

    The product complies with national standard: GB1094.1-1996 [Power Transformer Section 1 General], GB1094.2-1996 [ Power Transformer Section 2 Temperature Rise] , GB1094.3-2003 [ Power Transformer Section 3Insulation Level, Insulation Test and External Insulation Air Gap] , GB1094.5-2003[ Power Transformer Section The Capacity to Bear Short Circuit] , GB/T6451-2008[Three-Phase Oil-immersed On-Load Tap Changing Transformer Technical Parameters and Requirements].

    Detailed Discription:

    1. Low loss, and significantly energy-saving. The average no-load loss is 35% lower than prescribed by National Standard GB/T 6451-2008.

    2. The core laminations are made up from high-quality cold-rolled grain-oriented silicon steel sheets with chamfered joints and without punched holes, and are stacked without the upper yoke sheets in place, so that they are effectively improved no-load upper together with lower frame.

    3. Zigzag directed flow of oil are provided within the windings, so that all parts of the windings can be cooled more evenly.

    4. The regulating winding is a separate winding which apart from the high voltage main winding.

    5. The windings of one phase are assembled into an integral phase block before placing into the core.

    6. The winding manufacture, winding assembly core and winding assembly work are all proceed in totally closed clean department.

    7. Core frames in the form of a flat plate are used for clamping the core, and are joined together by side beams.

    8. Transformer tanks are fabricated with steel plates wide enough so that there are no weld joints on each surface.

    9. Diaphragm membrane is provided within the conservator, preventing direct contact of oil with air, protecting the oil from aging.

    10. Reliably sealed, and fine machined for sealed surface. Used double gasket grooves in their jointing surface and kept tight with high quality gasket material.

    11. High quality paint is applied as surface finish of the tank and exposed steel parts, after shot-blasting and pretreatment, thus ensuring a durable life and glossy surface.

    12. Quality assurance rules are also observed for all insulating parts, from raw material to final assembly.

    Applied in residential buildings, business center, shopping center, small factories and so on.

    Competitive Advantage:

    The core of 500kv power transformer is made of high-quality silicon steel sheets, and laminated by steps. It is advantageous in low loss, low nois and high short-circuit withstand capacity,etc.


    1.We can manufacture the product with different volumes and the performance parameters are depended on consumers' requirement.

    2.We can specially designed products according to various operation enviornment.

    3.The impedance loss, the off-load loss and on-load loss all can be differnent from the above table and it can be customized by the consummer.

    Please offer the following values to us before inquiring or ordering our product.

    (1) Rated capacity, (2) Voltage, (3) Range of tapping, (4) Vector group, (5) Short circuit impedance, (6) No-load loss, (7) On-load loss, (8) No-load current, (9) Rated freqency, (10) Cooling method, (11) Altitude, (12) Working environment and other special requirements.
