Products classified under HTS 2710.19.45.45
Transformer Mineral Insulating Oil
A highly refined mineral oil used in electrical transformers for insulation and cooling, consisting of mixtures of hydrocarbons with not over 50% of any single compound by weight. It falls under HTS 2710.19.45.45 as an insulating or transformer oil derived from petroleum, meeting the criteria for mixtures not elsewhere specified.
High-Voltage Switchgear Insulating Oil
Specially formulated petroleum-based oil for insulating high-voltage switchgear equipment, featuring low volatility and high dielectric properties from hydrocarbon mixtures. Classified under HTS 2710.19.45.45 due to its role as an insulating oil with balanced hydrocarbon composition.
Circuit Breaker Transformer Oil
Refined hydrocarbon mixture oil designed for cooling and insulating circuit breakers in power distribution systems. It qualifies for HTS 2710.19.45.45 as a transformer/insulating oil not containing biodiesel and with no single hydrocarbon dominating over 50%.
Synthetic Blend Insulating Oil
A blend of petroleum hydrocarbons and minimal synthetics for electrical insulation in distribution transformers, maintaining >70% petroleum base. Falls under HTS 2710.19.45.45 for its hydrocarbon mixture profile suited as insulating oil.
Power Transformer Cooling Oil
Petroleum-derived insulating oil optimized for heat dissipation in large power transformers, composed of mixed hydrocarbons under 50% single compound. Classified in HTS 2710.19.45.45 as a non-crude transformer oil preparation.
Electrical Grade Transformer Fluid
Purified mineral oil fluid for electrical transformers, ensuring arc suppression and insulation via hydrocarbon mixtures. Meets HTS 2710.19.45.45 for insulating oils not elsewhere specified.
Distribution Transformer Insulating Oil
Hydrocarbon-based oil for pole-mounted distribution transformers, providing dielectric insulation and thermal management. Under HTS 2710.19.45.45 as a qualifying mixture for transformer applications.
Industrial Grade Insulating Oil
Versatile petroleum oil for industrial electrical equipment insulation, mixed hydrocarbons preventing breakdown under high voltage. Fits HTS 2710.19.45.45 for non-specific insulating oils.
