POWER LUBE

TRANSFORMER

TRANSFORMER OIL



DESCRIPTION & APPLICATION

Power Lubes Transformer oils are widely used in Transformers, oil immersed circuit breakers and switchgears, Power Lubes Transformers oils are widely used in special transformers designed to operate of elevated to temperatures and in low maintenance/maintenance –free transformers designed to operate for longer periods.


PROPERTIES

  • Good dielectric properties resulting in minimum power loss.
  • Proven resistance to electrical stresses.
  • Low viscosity improves cooling.
  • High flash point resulting in low evaporation losses due to high thermal stability.
