IOSK oil paper insulated rent trsansfrrent transformers are of the head type. Each unit is designed in accordance with the latest IEC and IEEE/ANSI standards.

General Features

• Excellent insulation stress control using a fine graded bushing (less weight, less oil volume, increase safety and reliability)
• Maintenance free
• Safety (strong limitation of internal overpressure, shielded secondary windings, hermetically sealed)
• Special core class ratings TPS, TPX, TPY and TPZ are available
• Low reactance bar-type primary permits high short circuit currents and high primary current
• Essentially unaffected by stray external magnetic fields
• Excellent seismic performance due to optimized designs (low weight) and porcelain (cementing) and flanges (welding)
• Exclusive use of corrosion resistant materials (aluminum base and head)
