SC (B) 10/11 epoxy cast dry-type transformer is a dry-type transformer with strong mechanical strength, electrical strength, and good heat-resistance performance. It is made of F class epoxy resin mixture with filler, and after vacuum film degassing, the mixture is cast onto the glass fiber formed net frame to enhance the mechanical strength, electrical strength, and heat-resistance performance.

This type of transformer is an excellent product for urban power network transformation, which is very suitable for urban power grid, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, subway, underground power stations, laboratories, stations, terminals, airports, Pad-mounted substation, explosion prevention and explosion proof in urban power network, high-rise buildings, business center, theaters, hospitals, hotels, tunnels, subways, underground power stations, laboratories, railway stations, docks, airports and Pad-mounted substations, etc, which need high level of retardant, anti-explosion, anti-moisture performances.
Strong anti-short-circuit ability, low loss, low no-load current, strong impact resistance capability, low partial discharge, low noise, good heat sinking capacity.
Performance parameters are better than GB and IEC standards.。
Safe, flame retardant, fireproof, non-polluting, it can be installed directly in the load site.
Maintenance-free, easy to install, low operating costs.
High reliability, high mechanical strength.。
Good seismic capability.
Good anti-moisture & anti-corrosion features.
Good overload capability, in the absence of air-cooling, it can withstand 120% of the load long-term service.
Suitable to: substations located in densely populated, narrow urban places.
