S11-M Series Oil-filled Fully Sealed Distribution Transformer is applicable to plant, mine, petrol chemical and other power distribution system of 6KV, 10KV for industrial and agriculture. It features saves energy remarkably that no-load loss and no-load current are greatly decreased. ( 30%, 70% decreased respectively compared to S9 series). This type transformer is a new type energy-saving product.Two Types of core: Lamination core and wound coreWound core is made by low losses silicon steel, close structure, also called as R-core. The yoke section of the steel core columniation almost the round, HT and LT winding are wound on the core directly, with compact structure, low no-load losses, and low no-load current. It is adoption the fully sealed structure.Technibal Data For S11-M Type Transformers With No-load TapModel: S11-M Series
