Brand: WEIJI
Capacity: 30kVA~10000kVA
Voltage: 6KV~35KV
USES: voltage, capacity, frequency, connection group and loss can be customized according to customer requirements
This 6.6kV oil distribution transformer is fully oil-immersed, with low no-load loss and stable voltage output. It adopts high-quality silicon steel sheets and copper windings, featuring strong overload resistance and long service life. Completely sealed structure effectively prevents moisture and dust intrusion, ensuring safe and continuous operation for industrial, commercial and urban power distribution systems.
The automation rate of iron core production can reach 99%. The material is Baosteel high-magnetic silicon steel. It is equipped with high-end equipment such as horizontal and vertical shearing, fully automatic winding machine, vacuum drying/oiling system, etc., and has passed ISO/IEC international dual certification.
Remove bubbles and enhance insulation performance;
Uniform heat transfer improves the transformer’s withstand voltage and insulation performance, and recycles water to practice green production.
Daily production capacity of 50 units (efficiency increased by 3 times).
