On-Load Distribution Transformer https://www.ettgroups.co.in/on-load-distribution-transformer.htm https://www.ettgroups.co.in/on-load-distribution-transformer.htm Fri, 03 Dec 2021 00:00:00 +0530 Features of On-Load Transformer Magnetic Circuit is made using step-lap design for lower losses and low magnetizing current of core by using high quality CRGO material with grades such as ZDKH, ZDMH, AMORPHOUS, MOH, etc. Electric Circuit is made using electrolytic grade with 99.99% pure High Quality Copper from our regular and reputed vendor HINDALCO & STERLITE with Foil winding in L.V coil of transformer. High Dielectric Insulation property to withstand lightening impulse and voltage surges. ONAN through natural convection for effective cooling through axial and radial ducts.   Benefits:-  Due to On-Load Transformer the voltage at LV side remains in limit against the voltage fluctuations from HV side. For changing a tap, shut down of factory is not reliable. But due to the On-Load Transformer, you can change tap even when your factory is running. As there is RTCC panel with AVR (Automatic Voltage Regulator) LV side voltage remains in desire range by changing tap automatically. Due to On-Load Transformer efficiency of transformer increases, losses of the transformer and other electrical equipment decreases results in low power consumption, and overall life of the transformer and other electrical equipment increases.   Range : 630 kva On Load Transformer 750 kva On Load Transformer 800 kva On Load Transformer 1000 kva On Load Transformer 1250 kva On Load Transformer 1600 kva On Load Transformer 2000 kva On Load Transformer 2500 kva On Load Transformer 3000 kva On Load Transformer 3500 kva On Load Transformer 4000 kva On Load Transformer 4500 kva On Load Transformer 5000 kva On Load Transformer OCTC Transformer https://www.ettgroups.co.in/octc-transformer.htm https://www.ettgroups.co.in/octc-transformer.htm Fri, 03 Dec 2021 00:00:00 +0530 Range : 250 kva OCTC Transformer 315 kva OCTC Transformer 400 kva OCTC Transformer 500 kva OCTC Transformer 630 kva OCTC Transformer 750 kva OCTC Transformer 800 kva OCTC Transformer 1000 kva OCTC Transformer 1250 kvaOCTCTransformer 1600 kva OCTC Transformer 2000 kva OCTC Transformer 2500 kva OCTC Transformer
