        Specifications
        Place of Origin:Hunan, China (Mainland)
        Brand Name:Varelen
        Model Number:S11
        Usage:Power, step down
        Phase:Three
        Coil Structure:cylindrical
        Coil Number:3
        Rated capacity:10MVA
        Frequency:50/60Hz
        Standards:IEC60076
        Type:Oil Immersed
        Application:Outdoor
        Primary voltage:33KV 11KV
        Secondary Voltage:400V 415V 433V 388V
        Material:Copper Winding


        Characteristics
        *Energy saving: amorphous core would reduce no-load losses
        *Adopt amorphous alloy as the core’s material, no-load loss is lower 65% than S11
        *Security: strong ability of withstand short-circuit in the low voltage coil
        *Low voltage winding wound on the hard paper tube, enhancing the capacity to withstand short circuit for the transformer
        *Easy: maintenance-free
        *Adopt high quality anti-aging seals, ensure the transformer maintenance free
        *Three- column structure: could joint into Yy0, small
        *The 3 column core, winding connection symbol can be Yy0 .
