Petro-Canada’s LUMINOL™ family of electrical insulating fluids can help you minimize power loss and maximize productivity.

LUMINOL fluids:

  • withstand energy spikes and hot and cold weather extremes better than naphthenic electrical insulating oils
  • have naturally high oxidation stability that resists breakdown longer and helps provide extended service life, resulting in less maintenance and top-up

Petro-Canada produces LUMINOL fluids using the HT Purity Process combined with Hydroisomerization. These ultra-pure fluids are:

  • inherently biodegradable in natural environments
  • free of carcinogenic polynuclear aromatics (PNAs)
  • virtually non-toxic

LUMINOL delivers worry-free, corrosive sulphur-free performance in your transformer.
