Product Features

Advanced design technology

Adopting “3D+Parametric” design software, combined with more than 20 years of design and manufacturing experience within the group, we have realized automated design, cost optimization and simulation of transformers to ensure the advancement and reliability of product design.

High Reliability of High Voltage Coils

The high-voltage coil adopts a continuous structure with high mechanical strength and good heat dissipation, which avoids the problems of heat dissipation and voltage distribution of traditional multi-layer coils, ensures higher mechanical strength and reliability, and the partial discharge is less than 5 pC, which ensures the long-term stable operation of the product.

Strong Impact Resistance of Low Voltage Coils

Low-voltage coil adopts foil or longitudinal airway high-current spiral structure, national patent design, after vacuum pressure impregnation paint (VPI) treatment, with extremely high short-circuit and shock resistance, and at the same time has the characteristics of moisture-proof, dust-proof, and salt spray-proof, adapting to a variety of complex environments.

High-efficiency iron core design

The iron core is made of high-quality high permeability oriented silicon steel sheet, with 45° full diagonal stepping lap process and special moisture-proof and rust-proof coating, which significantly reduces no-load loss, no-load current and operating noise, and improves the overall operating efficiency.

Strict quality inspection

Transformers must undergo strict tests in line with national standards GB6450-1986 and JB/T501-XXXX before leaving the factory, including partial discharge, lightning impact, noise and many other key items, to ensure the high quality and reliability of the products.
