S□-M-L THREE-DIMENSIONAL DELTA TRANSFORMER

Overview

The solid core oil- immersed transformer is a new type of high reliability transformer with reasonable structure, better performance and lower manufacturing cost.

The product breaks through the traditional flat structure and adopts three-phase symmetrical three-dimensional structure. And because there is no air gap in the magnetic circuit, the magnetic direction of the silicon steel strip is completely consistent with the direction of the magnetic circuit, the three core columns are arranged in an equilateral triangle three-dimensional the three magnetic circuits are the same length, and are the shortest, and the processing kit is free of waste. Therefore, it is an efficient and energy-saving transformer using traditional material, but the operation noise is lower and the structure is more compact. Its excellent performance in reducing loss and saving materials is fully in line with China’s energy-saving policy.
