Lugao Power Co., Ltd has a complete transformer production line, with strict quality control at every stage of manufacturing, from procurement to shipment. Each year, the company sells over 100 transformers overseas, winning customers over with competitive prices and professional service, thereby establishing long-term partnerships. The minimum order quantity for Dry Type Air Cooling 3 Phase Transformer is one unit, with ample inventory and swift delivery.
LUGAO Dry Type Air Cooling 3 Phase Transformer utilize the principle of electromagnetic induction to achieve voltage conversion. During operation, when the primary winding is energized, it generates an alternating magnetic flux, which is coupled through the core to the secondary winding, thereby inducing an electromotive force. Air-cooled transformers use epoxy resin or silicone rubber as insulating materials. These materials possess self-extinguishing properties and do not pose safety hazards due to oil leakage. During the casting process, the pre wound coils are placed in specially designed molds, followed by the injection of an epoxy resin mixture and heating for curing. The resulting structure has high mechanical strength, effectively isolating external dust and moisture while protecting internal metal components. High-quality silicon steel sheets and windings are selected as materials, offering the advantages of low noise and low loss, making them suitable for environments such as office buildings, hospitals, and schools.
Dry type air cooled transformers can be customized according to customer requirements for voltage ratings, dimensions, and enclosures. Different materials with varying protection ratings can be selected to suit different operating environments. LUGAO's products comply with a series of international standards, such as CE and ISO, and the company will continue to innovate in design to create more energy-efficient and environmentally friendly dry type transformers.
