Product Overview
Kembot TF Transformer Oil is a highly refined naphthenic/paraffinic mineral insulating oil possessing superior dielectric properties, high breakdown voltage, and excellent heat dissipation.
Technical Specifications
| Specification Standard | IS 335: 2018 / IEC 60296 |
|---|---|
| Breakdown Voltage (BDV) | > 70 kV (After filtration) |
| Dielectric Dissipation (Tan Delta @ 90°C) | < 0.002 |
| Flash Point (PMCC) | > 140 °C |
| Pour Point | < -30 °C |
Performance Features & Benefits
- ✓ High dielectric breakdown voltage (BDV > 70 kV post-filtration)
- ✓ Low dielectric dissipation factor (tan delta) ensuring minimal power loss
- ✓ Excellent cooling efficiency via rapid convection circulation
- ✓ Zero corrosive sulfur (ASTM D1275B & DIN 51353 compliant)
- ✓ High oxidation resistance preventing sludge formation on transformer coils
Applications & Recommended Usage
- Power transformers, distribution transformers, switchgear, and circuit breakers.
- Capacitors, tap-changers, and high-voltage electrical bushings.
- Industrial substation and grid transformers.
Usage Guidelines: Filter and vacuum dehydrate prior to filling transformers. Test dielectric breakdown voltage (BDV) per IS-335 before commissioning.
