20KV Level S13-M Series Of Three-Phase Double-Winding Distribution Transformer With Off-Circuit Tap-Changer

● 20kv Ievel S13-M series of three-phase double-windinq distribution transformer with off-circuit tap-changer is using the type of S11-M serial full-sealed oiI-immersed type transformer it has nol oiI conservator moisture absorber and other devices. Coil is using Iayer-to-layer structure, ampere-turns evenly distributed, the insulation structure is reasonable and has a strong short circuit impact resistance Using the ripple fuel tank, wave wings can follow with the dilatation of transformer oil while dilatation, thereby make transformer internal maintain a certain pressure, enhance the reliability of the operational．

● Apply to power plant(station), substation(power distribution station) and industrial, business, building etc.

● Implement GB1094, GB6451 national standards etc．

    Note：

    1. For transformers with the capacity of 500 kVA and below, above the diagonal values of loss of load application Dyn11 connection g roup, below the diagonal load loss value applicable to Yyn0 connected node.

    2. The loss parameter in the table is also suitable for high voltage dual voltage 20(10) of the three-phase transformer.
