LUGAO is a transformer manufacturer with many years of manufacturing and export experience, selling more than 100 units annually. 750 KVA 3 Phase Outdoor Dry Type Transformers are currently very popular and suitable for use in schools, hospitals, and other locations. The minimum order quantity is one unit, with ample inventory, standard export packaging, and fast shipping.
The 750 KVA 3 Phase Outdoor Dry Type Transformer utilizes the principle of electromagnetic induction to achieve voltage conversion. During operation, when the primary winding is energized, it generates alternating magnetic flux, which is coupled through the core to the secondary winding, thereby inducing an electromotive force. Wrapping foil around the high and low voltage windings enhances short circuit resistance. Using a filtration casting method eliminates temperature-induced stress during transformer operation, and the use of epoxy resin makes the windings more heat resistant, ensuring equipment safety. The core uses high quality cold rolled silicon steel sheets, with 45° angled wide laminations stacked to reduce losses, and flat laminations that do not produce noise interference.
Outdoor Dry Type Transformers can be customized according to customer requirements for voltage ratings, dimensions, and housing materials, enabling appropriate customization for different environmental conditions. LUGAO's products comply with international standards such as CE and ISO. The company will continue to innovate in design to create more energy efficient and environmentally friendly transformers.
