3d Core Distribution Transformer Capacity: 30-2500kva

About 3D Core Distribution Transformer:-

Capacity: 30-2500kVA

The 3-phase dry-type transformer with non-encapsulated winding produced by UL certified NO MEX insulation system is safe, reliable, energy-saving, fireproof and easy maintenance. It features state-of-the-art design, rational structure, attractive appearance, all key performance indexes are better than set values of national standard, such as partial discharge level, no-load loss, load loss, noise level, suitable for use in hot environment.
SG(B)10, SG(B)11 and SG(B)13 series of transformers can be installed in foul and humid environment near lake, sea and river and region of stringent fire protection requirement and high load, suitable for use in the places such as high-rise building, airport, bus stop, dock, metro, hospital, power plant, metallurgical industry, shopping center, densely populated residential area, petrochemical industry, nuclear station, nuclear submarine and more.

a SG(B) series of transformer with well-designed winding structure and vacuum impregnation treatment does not cause partial discharge, without any crack during whole service life, and without occurrence of degraded insulation level
a HV continuous winding and LV foil winding are used, whole structure is treated by vacuum impregnation and solidification and supported with high-strength ceramic, with excellent capacity of withstanding transient short-circuit current
a Fire retardant, flame retardant, non-toxic, self-extinguishing, fire-proof
a Under burning condition of hot flame, SG (B) series of transformer does not generate any smoke
a The transformer is protected by Class H insulation (180a )
a Insulating layer is very thin and uniform, with high transient overload capacity, no forced cooling is needed, able to withstand 120% extended overload and 3 hours of 140% overload, because this type of insulating material is not subject to aging and it is elastic, immediate full loading under the condition of + 50a is available.
