Resin Casting
Cast resin Dry type transformer is ideal for installation and easy to maintain on account of both HV and LV windings are cast under vacuum, moisture cannot penetrate and therefore, no drying process is required even in humid conditions after long periods of service. The cast resin transformers comply with IEC60076-11.
CONSTRUCTION
CORE The core is manufactured from cold-rolled grain oriented (CRGO) silicon steel. The steel sheets are cut into required dimensions on automated machines thereby ensuring reduced air gap low exciting current and low noise. Each lamination is insulated from each other to ensure a long trouble-free lifetime of the core. Using 45° stepping all leaning lamination way to laminate. So the no-load current are reduced efficiently.
WINDINGS LV winding is manufactured with high quality foil conductor or copper wire and the ampere-turn is balanceable. The additional loss is low and the ability of anti-short is improved. Oil drawings of heat dispersion are scientifically used in the winding and the surface of heat dissipation is increased so the temperature is reduced and the ability of over-load is improved. HV winding is manufactured with high quality copper wire and excellent design structure. It improves the distribution of electric field. With lighting impulse analysis the ability of anti-lighting impulse has been improved.
