Product overview
This product is a saturated polyol ester (POE), classified as an eco-friendly and environmentally sustainable material. It exhibits low thermal expansion coefficient, high lubricity, high dielectric breakdown strength, exceptional flame resistance, and outstanding thermal-oxidative stability. It can be used as a standalone base oil or a synthetic base stock component and is widely applied in high-capacity power transformers (up to 238 kW), pole-mounted transformers, traction transformers, and tap-changer-equipped transformers.
