The S13-M·RL series fully sealed three-dimensional triangular-shaped iron core oil-immersed transformer breaks through the traditional planar structure of the transformer and adopts a three-phase symmetrical three-dimensional structure. Since there is no air gap in the magnetic circuit of the transformer core, the winding is tighter, and the magnetic direction of the silicon steel strip is exactly the same as the direction of the magnetic circuit. The three core columns are arranged in an equilateral triangle, and the lengths of the three magnetic circuits are the same and the shortest. The transformer structure is more compact, which greatly reduces the no-load loss and noise of the transformer during operation.

S13-M·RL series fully sealed three-dimensional triangular coil core oil-immersed transformer. Because the core adopts three-phase symmetrical three-dimensional structure, the transformer tank also adopts an approximate triangular structure. The transformer has compact structure and small footprint; the transformer tank is designed to be fully sealed. The structure, the oil in the fuel tank does not contact the outside air, prevents the oxidation of the oil, prolongs the service life of the transformer, and also saves maintenance costs for the customer. Now suitable for ordinary oil-immersed transformers, it is suitable for S13-M·RL series fully sealed three-dimensional triangular coil iron core oil-immersed transformers, especially in places where power shortage occurs.
