Cast Resin Transformers
INESING cast resin transformers are suitable for distribution and industry with a power up to 20 MVA; the medium voltage windings are embedded in epoxy resin and are suitable for both outdoor and indoor applications.
Our transformers can be used in substations for public buildings, hospitals, airports and in places where the use of oil immersed transformers is limited due to fire risk or for environmental protection reasons such as Mines, tunnels, marine applications , cranes, offshore platforms, wind turbines, underground water reservoirs and food processing plants.
