CEEG SC(B) Series Epoxy Cast Dry-Type Power Transformers

PRODUCT OVERVIEWS

Low No-load Loss

Made with 0.18mm high-quality, high-permeability silicon steel sheets with full slanting joints and multi-stage step process, resulting in low no-load losses.

Advanced Technology

High-voltage coils are produced using imported German HEDRICH vacuum casting equipment; fully automated online mixing ensures bubble-free casting of coils with minimal partial discharge.

Superior Performance

Utilizes electric field, thermal field, and magnetic field simulation analysis; among the first in China to pass KEMA's E2, C2, and F1 tests.

Energy Saving and Environmentally Friendly

Resin cast insulation encapsulation is resistant to corrosion, flame-retardant, explosion-proof, low-loss, low-noise, environmentally friendly, and pollution-free.

Manufacturing Process:

CEEG's "3D + Parametric" design software enables automated design, cost optimization, simulation, and emulation, fully considering national and industry standards and ensuring the advanced design of products.

High-Voltage Winding

The high-voltage winding conductors are made of high-quality materials, with reinforcement fillers using long and short cut glass fiber mats. They are cast under vacuum using the world-class HEDRICH vacuum casting system, achieving a partial discharge level of less than 5 pC.

Low-Voltage Winding

The low-voltage windings are made with high-quality pin conductors, wound on automatic box winding machines. These machines utilize "wire hydraulic energy-saving tension curling device," with ±0.5mm high-precision detection and advanced hydrogen arc welding technology.

Core

The core is made of high-quality, high-permeability oriented silicon steel sheets, featuring a 45° full slanting step lap process. The surface is coated with a special moisture-proof and rust-proof coating, effectively reducing no-load losses, no-load current, and noise levels.

Testing and Inspection Technology:

All products undergo rigorous testing before delivery according to relevant standards and customer-specific requirements, including partial discharge testing, lightning impulse withstand testing, noise testing, and other mandatory inspections.
