\ FEATURES \

1. The iron core adopts high-quality high magnetic conductivity silicon steel, a full oblique joint, and a multi-stage stepping process, with low no-load loss.
2. The iron core adopts a three-dimensional fastening structure. Under various working conditions, the iron core has no transverse and longitudinal displacement.
3. High and low voltage windings adopt a combined winding process, combined with VPI vacuum pressure impregnation and high-temperature curing, with high mechanical strength.
4. The shell adopts an oval structure, with low product height and short length, which is suitable for the space requirements of various mines.
5. The shell adopts the corrugated cylindrical structure of patented technology, with no ponding and dust on the top, good heat dissipation effect, and strong explosion-proof performance.
6. It adopts the eight-point fastening method, which is firm and reliable and can go down the well vertically.
7. Nomex Paper insulation system is adopted, with heat resistance up to grade C, recyclable, safe, and environmental protection.
8. The integrated design scheme supplies power to the flameproof frequency converter and communicates with the frequency converter to complete the functions of equipment operation status monitoring, fault breaking, and centralized control.
 

\ 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.
