S11 Sealed силовой трансформатор

S11 Sealed Power Transformer Structural 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 (630KVA and above). All the wires are drawn by using oxygen-free copper. Between he high-low voltage winding layers are insulated by diamond-shaped grid point gummed paper. 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.
