Model Description

Technical Parameters

1. The high-quality cold rolled oriented silicon steel sheet is selected for the iron core, which has 45° fully beveled seam and five-step folding iron mode. Both the core column and the iron yoke have the multi-stage round section shape, low no-load loss and low noise can be obtained.

2. According to the transformer capacity, the flat copper wire wrapped with double glass paints is adopted as the high-voltage conductor, and Grade H glass fiber cloth and glass felt are adopted for inter-laminar insulation. The low-voltage conductor is wounded with copper foil, epoxy resin prepreg cloth is adopted for inter-laminar insulation. Both of them have very high mechanical strength and resistance to sudden short circuit.

3. The coordination structure between the low magnet steel pulling plates and clamps is adopted, sand blasting and plastic spraying are conducted, and the overall structure is artistic and has high mechanical strength.

4. Each phase is equipped with the independent axial flow blower and split-type thermostat, which can effectively reduce temperature rise, improve transformer output capacity, and guarantee safe operation of the transformer.

1. Safe, fire-proof and pollution-free. It can be directly operated at the load center.

2. Adopting the HTT technology from Germany. with high mechanical strength, strong anti-short circuit capacity, small local discharge and good thermal stability.

3. Small volume, light weight, less space occupying and convenient installation

4. Low loss, low noise, maintenance-free and remarkable energy-saving effects

5. Damp-proof, mildew proof, salt fog proof, good heat dissipation, suitable for operation at high elevation, high humidity and other harsh environments

1. The elevation shall not exceed 1000m

2. Ambient temperature      Maximum temperature                             +40℃/+104oF

                                            Maximum daily average temperature      +30℃/+86oF
