S9 20KV oil HV transformer

S9 20KV Oil Type High Voltage Transformer

Structure Characteristics:
1. Core: The three-phase three-pillar  structure inside and outside the box rolling. Center column for the multi-step cross  section. After rolling core using vacuum annealing to remove stress, bending clamping groove. Pull screw to tension the body. Core surface brush special angle glue, to ensure core is not deformed and not rust.
2. Coil and the body: low-voltage coil made up of 1 to 6 wires together to four layers or double-cylinder type (500KVA and below), or spiral-type. High voltage coil axial direction Oil conduit and high-low voltage main oil gap are Stays curtain structure. Iron yoke insulation and trapezoid pads as one, so that the body uniform compression, body structure using the new safety board positioning, vertical and horizontal orientation, ensuring that is no displacement.
3. Tank: The ripple tank, sealed structure, no leakage, maintenance-free.
