High Reliability: With advanced design, manufacturing techniques, and stringent quality control system, the transformers we offer have received good reputation in both local and overseas markets.

Excellent core construction: A unique computer-programming core manufacturing machine with functions of automatic cutting and stacking of silicon steel strips is utilized in our products. Advanced V-notch and step-lap construction are also implemented to achieve the best performances in the core, with visible advantages such as low sound level, low no-load loss and low exciting current.

Surge-proof winding: The windings of the power transformers that we offer are specially designed to be surge proof. By employing a voltage oscillation analysis program, the voltage oscillation is calculated in the windings which a simulated surge is applied. An appropriate insulation arrangement is adopted for the windings according to the results of simulation to ensure its surge-proof ability.

Advanced vapour-phase drying system: In order to heat the interior (core and winding assembly) in a rapid and even manner, the most advanced vapour-phase drying oven is utilized to allow the insulation materials to be dried thoroughly without sacrificing any performance.

High-efficiency cooling method: The windings of the power transformers adopts a directed flow construction, which ensures the insulating oil flow through all parts of windings rapidly and evenly to increase cooling efficiency and reduce hottest-spot temperature.

Variability of countermeasure for leakage flux: Appropriate preventive means are adopted in order to avoid local overheating by the leakage flux. For example, equipping a magnetic shield on the tank, according to the magnitude of leakage flux calculation by analysis software.

Sufficient strength against short-circuit electromagnetic mechanical force: The ampere-turns distribution between primary and secondary windings is designed to be as balanced as possible according to the detailed short-circuit stress calculation by analysis software. The selection of materials and the pre-compressing process of the windings have been given special consideration to provide sufficient strength of windings against the short-circuit electromagnetic mechanical force.
