Box transformer is a power product that combines high and low voltage cabinets and transformers. Our box transformers can be designed according to the actual needs of customers. For example, the number of inlet and outlet lines of the high-voltage ring main cabinet, the number of inlet and outlet lines of the low-voltage cabinet, the inlet and outlet line methods, etc., we can customize the design according to the actual needs of customers. Box transformers are generally used outdoors and have excellent dust and water resistance. Our box transformers are exported to many customers in Africa and can meet the EEU standard of Ethiopia. This standard has very high requirements for box transformers, but the box transformers purchased by our customers can pass the inspection of the Ethiopian Electricity Authority and be successfully installed and used.
