PTT Hivolt 99

PTT Hivolt 99 is an inhibited type insulating oil for transformers, produced from high quality base oil and anti-oxidation additive, to prolong oil service life and exhibits high dielectric strength.

  • Provides thermal stability, low volatility, high flash point and good flow characteristic.
  • Minimizes insulating oil oxidation reaction and sludge formation.
  • Compatible with wire coating material.
  • Used to transfer heat in transformers, switch gears and other electric equipment.
  • Suitable for use in oil filled capacitors, circuit breakers, switches and other equipment.
  • ASTM D 3487 : 2000 (Type II)
  • IEC 60296 : 2003 (Inhibited)
