DESIGN & MANUFACTURE PROCESS


Based on more than 30 years of design, manufacturing, and experimental experience in the transformer industry, CEEG has developed a set of advanced three-dimensional + parametric design software, which can realize automatic design, cost optimization, and simulation.
Fully considering the requirements of the national and industrial standards, ensuring the advantageous design of products.

The high-voltage winding conductor is wound with a high-quality conductor and reinforced with long and short-cut glass fiber felt. Poured by the advanced Heidrich vacuum pouring system under vacuum. Effectively restrain the occurrence of partial discharge, and the partial discharge is ≤ 5pc.

The low-voltage winding adopts a high-quality foil conductor and is wound on an automatic foil winding machine. The foil winding machine adopts the patented technology of foil wire hydraulic energy-saving tension crimping device, high-precision detection of ±0.5mm, and advanced argon arc welding technology, which plays a key role in ensuring the quality of coil winding.

The iron core adopts a high-quality high magnetic conductivity-oriented silicon steel sheet, a 45° full oblique step lapping process, and the surface adopts special moisture-proof and rust-proof coating, which effectively reduces the no-load current and noise level.

 

 
Packaging & Shipping

USE & PACKING


 SERVICE CONDITIONS - The installation site shall not be flooded by water, the altitude shall not exceed 1000m, and the ambient temperature shall not be higher than 40ºC. The relative humidity is 100%, and the environment is 40ºC to -25ºC (-25ºC requires an on-load tap changer and temperature controller).


PACKAGING & TRANSPORTATION - The products can be partially disassembled and transported (such as on-load tap changer, temperature controller, air cooling device, enclosure, etc. can be packaged separately) or packed as one piece in packaging boxes for transportation.


VISUAL INSPECTION BEFORE INSTALLATION - After opening the package, remove the protective device and check the external conditions, especially paying attention to the mechanical integrity of the coil and iron core, and the bolt fastening at the connection.


INSPECTION BEFORE OPERATION - Measure the DC resistance of high voltage and low voltage windings. Then check the grounding of the iron core to see whether the grounding is reliable and whether foreign matters are overlapping. Last to test the insulation resistance.

ENERGIZING - Before putting into operation, the transformer shall be put into trial operation under no-load, and the protection system shall be checked and adjusted after 3 times of impulse closing.
