Description of the Product

The D11-M.R series single-phase oil-immersed transformer uses R-type wound core technology to form a seamless core, reducing magnetic resistance and losses. Annealing treatment improves mechanical properties, reduces noise and temperature rise. The windings are made of high-quality oxygen-free copper wire, and the high-voltage winding is multi-layer cylindrical. All fasteners are treated with special anti-loosening. This product has the characteristics of high efficiency, low loss, and can save a lot of energy and operating costs, is the preferred product of small-scale power distribution. It has been widely applied in the rural power grid, remote area and pole mounted distribution system all over the world.
