SC (B) 10/11 Epoxy Cast Dry-Type Transformer

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.

Model Explanation

Features

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.

Normal service conditions
