The head type IOSK oil paper insulated current transformers follows the current IEC and IEEE/ANSI standards. It is outstanding in controlling insulation stress using fine graded bushing. The advantages of using fine graded bushing are the less weight and oil volume, increase safety and dependability. It is safe to use for it limits overpressure strongly, it has shielded secondary windings and is hermetically sealed. TPS, TPX, TPY and TPZ special core class ratings are available. Low reactance bar-type allows high short circuit currents and high primary current. It is not affected by stray external magnetic fields, it has optimized designs that lessens weight, porcelain for cementing, and flanges for welding which makes it excellent in seismic performance and it has exclusivity in the use of corrosion resistant materials like the aluminum base and head.
