SCB10 cast resin transformer
The cast resin transformer refers to power transformer of which winding is enveloped with solid insulation. The epoxy resin is taken as the insulation materials for the epoxy resin dry transformer. The high- and low-voltage winding is wounded with the copper strip (foil), and epoxy resin is cast in vacuum for curing, constituting the high-strength fiber reinforced plastics structure. The insulation class includes Class F and Class H. The epoxy resin dry transformer has the features of good electrical performance, strong resistance to lightning shock, strong anti-short circuit ability, small volume, light weight and so on. The temperature display controller can be installed, and the operating temperature of the transformer winding is displayed and controlled, so as to guarantee normal service life of the transformer.

1. Oil-free, pollution-free, flame retardant and fireproof.
2. Low loss, high efficiency and low noise.
3. Small partial discharge capacity (generally below 10PC), high reliability. It can guarantee long-term safe operation, and the life can be up to 30 years.
4. It can resist crack and temperature change, and has high mechanical strength and strong resistance to short circuit capability.
5. The moisture-proof performance is good, it can be in normal operation at the humidity of 100%, and it can be put into operation without drying after stoppage.
6. The independent transformer chamber is not required, it is not required to lift the core for maintenance, and the load bearing beam is not required, which saves floor area for civil engineering; it is oil free, will not generate toxic gas, and will not pollute the environment. The oil sump and other auxiliary buildings are not required, and the construction cost of construction cost is reduced.
7. Installation is convenient without commissioning, and maintenance is almost not required; it is not required to replace and check oil seal, and the operation and maintenance cost is low.
