Product Overview

20kV, SC(B) series dry-type transformers can be used as the upgrading products of oil-immersed distribution transformers, and are the products with the best performance among all kinds of dry-type transformers, especially suitable for urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, subways, stations, docks, airports, underground power stations, laboratories, combined substations and other important places.

Product Features

1.All-copper winding structure: High-voltage/low-voltage are made of copper (copper wire or copper foil), glass fiber reinforced epoxy resin vacuum casting, forming a high-strength cylinder, excellent mechanical properties, low local discharge electrode, excellent reliability.

2.safety and environmental protection: Flame retardant and explosion-proof design, self-extinguishing insulating materials do not produce toxic gases, no risk of environmental pollution, short circuit without arc potential.

3.Strong weather resistance: Coil moisture resistance and corrosion resistance, special anti-corrosion treatment of the iron core, adapting to 100% humidity and harsh environments, intermittent operation without maintenance.

4.High reliability: Excellent performance of short-circuit and lightning impact resistance, to ensure the stability of the power grid.

5.Efficient heat dissipation: Thin resin layer optimizes heat dissipation, standard natural air cooling (AN), optional air cooling system (AF) to enhance overload capacity.

6.Economic and efficient: Low-loss design, energy-saving and maintenance-free operation, low life cycle cost.

7.Compact and flexible: Small size, light weight, installation without oil tank/fire fighting facilities, saving space and infrastructure costs.

8.Nearby deployment: Can be dispersed in the load center, shorten the low-voltage lines, reduce the comprehensive investment.
