SBK/SGThree phase dry type transformer

Product overview:

The three-phase isolation transformer not only has the function of variable voltage in the power grid, but also can isolate the three harmonic of the power grid to the equipment, primary and secondary copper foil shielding, effectively protect the harmonic interference of the power grid to the equipment,. Particularly suitable for imported equipment (380V into 220V208V200V out, 380V into any voltage output) specification 1KVA-1600KVA, suitable for AC 50 ~ 60HZ, input and output voltage is not more than 3300V of all kinds of three-phase power supply occasions. The input and output voltage products (three-phase or multiple input and output), connection mode, adjusting the tap position, the distribution of winding capacity, equipped with a secondary winding, outside the box (depending on the use of the environment, can choose) meticulous design and manufacturing according to the requirements of users.

Product features

This series of isolation transformer has the advantages of fire prevention, moisture-proof, safe and reliable, saving energy and convenient maintenance

 

Range of use

The series of isolation transformers are widely used in Metro, high-rise buildings, airports, stations, printing, machine tools, terminals, industrial and mining enterprises and tunnel power transmission and distribution and import equipment use.
