Product Introduction
SCOTECH delivered one unit of 2840KVA dry type rectifier transformer to Canada in 2015, it supply power to a metro station in Montreal as a traction transformer, this transformer feed a diode rectifier, 6 phase, 12 pulses, which feeds the load with DC voltage 750v, the rectifier is not equipped with smoothing or interphase coil on 750v side, we are responsible of the compatibility of the transformer-rectifier system. The K factor of the transformer is K13, which means the transformer is operating in a heavy harmonic environmental, which is considered by us during design. The transformer is working 20/24 hour, 365 days at -35 to +40 ℃ and 100% humidity. The transformer is able to work at 150% of the rated power with peak of 300% for 20seconds due to peak of voltage every 3 minute without exceeding the temperature of 100℃,the temperature rise is 80℃ max at rated power, the insulation of the copper winding is adopt NOMEX with class H(220℃)
Traction transformer is one of the most important equipment, is the core part of the entire electric traction system, to ensure the stable operation of locomotive, high-speed rail and other rail vehicles. Our 2840KVA Traction Power Transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.
SCOTECH is specialized in transformer manufacturing for more than 20 years, our transformers are widely used in the world and we exported our transformers to more than 50 different countries.

Why transformer is used in Rectifier?
Rectifier circuits are essentially AC to DC where the AC voltage is rectified to a set DC voltage. … And in Higher voltage cases the transformer is used as a step up and then it is rectified, this is done to put the voltage above the threshold and the necessary voltage.
FAQ
1. Where is your main market?
We had exported our transformers to more than 30 countries in the world, our main market is Africa countries, South and North American countries, and Asia countries.
2. What certificate do you have?
We have KEMA, CESI, CTQC type test report for our transformers.
3. How long is your delivery time?
30 days after drawing confirmed by buyer for distribution transformers below 5000kva, bigger transformers depend on the capacity and components, normally 30-90days(with imported components)
