33 11 kv 20 mva power supply transformer Features:

1.High-voltage winding with copper strip winding technology to enhance lightning surge resistance.

2.Low-voltage winding with copper foil winding technology, using premium Grade A insulation materials for high-quality insulation.

3.Minimal leakage, high mechanical strength, and strong short-circuit withstand capability.

4.Iron core with a 45° fully mitered stepped structure: Precision machining is ensured through the use of laser cutting machines and CNC punching, shearing, and folding equipment.

5.Electrostatic powder coating treatment, providing long-lasting paint adhesion (corrosion resistance exceeding 100 hours, hardness ≥ 0.4).

6.Fully sealed structure, maintenance-free, and maintenance-free, with a normal operating lifespan of over 20 years.

7.High-quality cold-rolled grain-oriented silicon steel sheets with mineral oxide insulation for the iron core material (sourced from Baosteel and Wusteel in China).

8.By controlling the process of cutting and stacking the silicon steel sheets, losses, no-load current, and noise levels are minimized.

9.Special reinforcement of the iron core to ensure the transformer's structural integrity during both normal operation and transportation.

10.Low-voltage winding made with high-quality copper foil for excellent insulation resistance.

11.High-voltage winding typically made with insulated copper wire for exceptional resistance to radial stress caused by short circuits.
