Product Description

Product Introduction

S11-M fully sealed oil-immersed power transformer is suitable for power systems with AC 50Hz, rated working voltage of 10kV and below, as distribution transformers in petroleum,metallurgy, chemical, textile, light industry and other enterprises and places with large dust.The product conforms to the standard: GB1094.1-5

This technical drawing illustrates three orthogonal views of an oil-immersed power transformer, a critical asset in electrical distribution systems. The views-front (left), side (middle), and top (right)-reveal the transformer's structural design, dimensional specifications, and functional features, essential for manufacturing, installation, and maintenance.
