SCB11-3150KVA dry-type transformer selects overseas cutting-edge production technology, design drawings and technical data are complete, appropriate and clear, advanced manufacturing equipment, stable processing technology, perfect measurement methods, and bring a solid guarantee for the development of high-quality goods for the enterprise.

SCB11-3150KVA干式变压器特性

1. The high-voltage winding is made of enameled copper wire, and the low-voltage winding is inducted by copper berth coil. The high-pressure winding is filled with glass fiber felt, and poured with some epoxy resin glue imported with filler in a vacuum state, which cures to produce a firm overall, high impact toughness, no partial discharge, and good stability.

2. Group combustion, explosion-proof type, non-damaging environment, energy-saving type, can be installed in the load center.

3. The solenoid coil is not subject to moisture, and the iron core and clamp can be operated from 1oo% air humidity and other extreme environments with special technical treatment. Intermittent operation does not have to be solved by dampness.

4. High anti-short-circuit fault, high lightning impact technology and large load capacity.

5. The epoxy resin cable sheath on both sides of the electromagnetic coil is thin and has good thermal conductivity. The heat dissipation method is generally gas cooling (AN). Substations of any waterproof class can be equipped with an air-cooling system (AF).

6. Low consumption, obvious power-saving effect, economic development operation, and durability.

7. Small size, light weight, small floor space, simple installation.

8. As a new generation of oil-immersed transformers, SC (B) oil-immersed transformers are suitable for power supply systems in the following places: multi-storey buildings, commercial plazas, dramatic defense, hospital outpatient clinics, factories and mining enterprises, water drilling platforms, ships, subway stations, subway stations, airports, power stations, residential areas and skyscrapers
