Petro-Canada LUMINOL TRI – Premium Transformer Oil for Superior Electrical Performance

Petro-Canada LUMINOL TRI is an advanced transformer oil engineered to deliver exceptional protection, reliability, and thermal stability for power and distribution transformers.

Unlike traditional naphthenic-based insulating fluids, LUMINOL TRI transformer oil also uses ultra-pure, severely hydrotreated isoparaffinic base oils. This next-generation transformer fluid is designed to minimize power loss, extend service life, and maximize equipment productivity—even in the harshest operating environments.

This premium oil for transformers is free of corrosive sulfur compounds, eliminating the risk of transformer breakdown caused by sulfur-induced corrosion.

LUMINOL TRI also boasts outstanding cold weather performance, making it a reliable choice for regions facing wide temperature extremes. Its superior oxidation resistance helps reduce fluid degradation over time, meaning fewer top-offs, less maintenance, and improved transformer uptime.

Key Features & Benefits:

• Made from ultra-pure isoparaffinic base oils for cleaner, longer-lasting performance

• No corrosive sulfur—no need for passivators or additional inhibitors

• Excellent heat transfer properties help transformers run cooler, even under heavy load

• High dielectric impulse strength improves insulation under high-voltage stress

• Negative gassing reduces the risk of transformer failure due to hydrogen bubble formation

• Full compatibility with naphthenic transformer oils simplifies transitions and fluid mixing

• Virtually non-toxic and inherently biodegradable—safer for workers and the environment

• Free from polynuclear aromatics (PNAs), lowering health and environmental concerns

In addition, LUMINOL TRI is well-suited for use in high-capacity power transformers, distribution transformers, pad-mounted units, pole-mounted systems, and free-breathing equipment. It performs reliably under continuous high voltage and frequent load spikes. Whether you’re operating in freezing climates or sweltering industrial zones, this transformer fluid offers consistent protection and thermal efficiency.
