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)
