Inhibited Transformer Oil INH-T2 – 210L Drum (PCB-Free, Eskom Tested)
Greyhound INH-T2 is a premium inhibited transformer oil formulated from high-purity virgin base stocks. It delivers high dielectric strength, very low pour point and excellent oxidation stability for reliable insulation and cooling in power and distribution transformers, switchgear, rectifiers and circuit breakers. The product is PCB-free and has been Eskom tested (meets Eskom required parameters; pending final Eskom Approval).
