Overview The transformer equipped with on-load tap-changing switch is called as On-load tap-changing Transformer. On-load Tap-changing Transformer is a transformer whose several tap joints are united from transformer winding passing through on-load tap-changing switch and change tapping location and its effective number of windings in case of ensuring not to rupturing load current and thus making use of changing transformer ratio to aim at unchangeable output voltage. Energy during changing and tapping process usually utilizes transition resistance to absorb limitation cycle current. Iron core is in ladder shape replace traditional piling way of iron core as well as the inner distribution of magnetic way, which decrease no-load consumption, no-load current consumption and noise pollution by 20%, load consumption also decrease by 10%. This new product applies CAD tool and marked with advanced design, reasonable structure, high quality material, it is according to IEC60076 & GB1094-1996 and IEC60616. On-load Tap-changing Transformer is mainly used for: 1).Stabilizing electric-network voltage in every on-load center to increase quality of power supply. 2).Distributing loads between networks using on-load tap-changing acting as interconnection transformer between two networks. 3).Site where utilizing power supply with on-load regulation current and power to increase production efficiency 4). Site where voltage should be strictly controlled, such as electric industry, medicine etc. 2. Normal service conditions 1).Elevation cannot be over 1000m indoor oroutdoor 2).Highest ambient temperature +40 highest daily average temperature +30 3).Highest annual average temperature +20 lowest temperature -25. We can provide transformer operated in special conditions according to the requirements of users.
