    h. Temperature rise limit: The average winding temperature rise measured by resistance method under the ambient temperature of 40 ℃ and the rated load, F-class insulation shall not exceed 100 ℃, and H-class insulation shall not exceed 125 ℃.
    i. Refer Transformer performance list (at pf = 1, 75 ° C).
    j. The above performance is a reference value.All performances should be marked based on the final approval information or test report.
    k. For other specifications transformers, relevant technical data will be provided separately according to customer requirements.
  5. Transformer Construction
    a.core:The cold-rolled directional silicon steel sheet material with high magnetic permeability and low iron loss is laminated with V-notch 5 steplap core method. The surface of the completed core is additionally coated with special resin to prevent moisture And anti-corrosion. The core is grounded and visible to the base.
    b.fastener: The core is fixed with Slot iron and screws of sufficient strength. The structure of the core and Slot iron is to be solid and stable, and to avoid subjecting the core to external stress to affect iron loss and noise. All fixed metals other than the core have anti-rust treatment.
    c.coil: High-voltage coils use electrical copper (or aluminum) conductors. The coil insulation is reinforced with a special glass fiber resin, and the resin is poured in an automated pouring equipment and under vacuum. The coil after the resin is poured is cured by heating.Partial discharge test is performed on the high-voltage coil after molding to confirm that it does not contain any Cavity & Air Void so that it has the best electrical and mechanical characteristics.Low-voltage coils are made of copper (or aluminum) conductors and pre-impregnated resin materials (Pre-Impregnated) wound on a mold at the same time and heat-hardened. The resin is poured above and below the coil to increase its strength.After completion, the high and low voltage coils are moisture-proof, non-flammable, non-combustible, and automatically extinguished.The ends of the high and low voltage coils and the upper and lower slot irons are fixed with a support with elastic gaskets to tighten the coil and absorb the thermal expansion and contraction of the coil.
    d.Terminal: Except for the lead-out terminals of the high-voltage coil, the connecting wires of the live parts are covered with heat-resistant insulation, and all lead-out terminals adopt NEMA standard copper connectors. The terminals of the low-voltage coil are led out by a bus, and the terminal head of the bus should comply with the customer (or NAME standard).
    e.Tap changer: The high voltage side winding of the transformer is provided with taps that can adjust the voltage under no voltage and current. These taps are drawn from the winding surface so that the voltage of the tap can be switched after the power is cut off (under no voltage state).
