Product Introduction
The rated power of the transformer is 750 kVA with ONAN cooling. The primary voltage is 13.8kV with ±2*2.5% tapping range (NLTC), the secondary voltage is 0.48kV, they formed a vector group of Dyn11.
Our 750 KVA power transformer is designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.
We ensure that each one of our delivered units has undergone rigorous full acceptance testing. We provide one-package service from consulting, quoting, manufacturing, installation, commissioning, training to after sale services, our products are now operating in more than 50 counties in the world. We aim to be your most reliable supplier as well as your best partner in business!
Basic technical requirements for installation of transformer
1. The transformer's high-voltage down lead and high-voltage bus must adopt copper core or aluminum core rubber insulated wire; 2. The different phase to phase distance of high-voltage bus, high-voltage down lead and drop out fuse must be less than 300 mm;
3. The distance between the low-voltage side line and the high-voltage down lead shall not be less than 150 mm;
4. It is strictly prohibited that the low-voltage line passes through the high-voltage down lead, and the sag of the lead up and down lead should be neat and consistent;
5. The transformer shell, circuit breaker, arrester ground wire and transformer low-voltage side zero line should be grounded together first;
6. The transformer platform should be kept horizontal and the height difference of diagonal line of the table should be less than 30mm.
Manufacturing Process

Our Exhibitions

Packaging and Transportation
The transformers was send to sea port by truck, it was transported with oil in the tank, the accessories such as radiators are packed in plywood boxes and the transformer body was nude in the ship, we also equipped impact recorder for the transformer.
