MX Series High Performance Transformer Oil

Our MX Series transformer oil serves as the critical lifeblood of power distribution systems, combining exceptional dielectric strength with long-term thermal stability. Refined from high-purity base oils, it effectively prevents arcing under high voltage loads while rapidly dissipating heat from transformer coils. Available in VG 15, 22, and 32 grades, with RoHS and SGS certification for industrial clients in power generation and distribution.

The MX Series is a mineral-based transformer oil formulated for power generation and distribution systems. Refined from high-purity base oils, the product fulfills two core functions in electrical equipment: it acts as an electrical insulating medium to isolate energized components, and it transfers heat generated by live coils to maintain stable operating temperatures.

This product line includes three ISO viscosity grades to adapt to diverse operating conditions, serving industrial clients in power transmission, grid operation, and electrical equipment manufacturing. All grades of the MX Series comply with relevant industrial safety specifications and hold third-party testing certifications to support commercial procurement and project acceptance procedures.

MX Series Electrical Insulating Oil

Core Performance Characteristics of MX Series Electrical Insulating Oil

Dielectric Insulation Performance

The MX Series transformer oil has high dielectric strength, which reduces the risk of arcing between energized components under high-voltage loads. This insulating property supports stable operation of medium and large power transformers, and helps maintain consistent equipment performance during voltage fluctuations and peak load periods. The dielectric capacity remains stable after long-term immersion with electrical components, without rapid performance degradation.

Thermal Conductivity and Low-Temperature Fluidity

This series of insulating oil has a low pour point, which supports normal equipment startup in low-temperature and cold climate regions. Its fluid properties enable efficient heat transfer from transformer windings and cores to the external cooling structure, lowering the risk of coil overheating during continuous peak load operation. Different viscosity grades are designed to match heat dissipation requirements under different ambient temperature conditions.

Oxidation Stability Performance

The MX Series transformer oil has oxidation resistance for long-term operation at elevated temperatures. During sustained high-temperature operation, the formulation slows the formation of sludge and acidic byproducts in the oil. This property helps extend the service cycle of the oil in equipment, and reduces the frequency of oil replacement and related maintenance costs for commercial users.

Buyers may select the appropriate grade by matching the viscosity grade with their equipment’s design requirements, local ambient temperature, and operating voltage level. Technical consultation is available for projects with special working conditions.

Application Scenarios for MX Series Mineral Insulating Oil

MX Series transformer oil is designed for oil-immersed power equipment in power generation facilities, transmission networks, and distribution systems. Typical use cases include power transformers, distribution transformers, and other electrical devices that require both insulating protection and heat dissipation support.

VG 15 grade is intended for high-voltage equipment and projects located in extreme cold regions. VG 22 grade is suitable for conventional distribution transformers and general power grid facilities. VG 32 grade adapts to heavy-duty transformer equipment and industrial environments with long-term high ambient temperatures.

Packaging, Certifications & Custom Formulation Services

For bulk commercial procurement, the MX Series transformer oil is available in two packaging specifications: 200L steel drums and IBC bulk tanks. Packaging can be adjusted according to customer requirements for specific projects.

The product supports multiple logistics methods including sea freight, air freight and land transport to accommodate global delivery needs. Accepted payment terms include T/T, L/C and PayPal.

All grades of the MX Series have obtained SGS test reports and meet RoHS compliance requirements. Production processes are managed under the ISO 9001 quality management system to ensure consistent product performance across batches. For enterprise customers with unique performance or formulation needs, OEM and ODM custom formulation services are provided by our technical team.

FAQ About MX Series Transformer Oil

How do I select the correct viscosity grade for my equipment?

Choose VG 15 if your equipment operates at high voltage levels or is installed in regions with extremely low winter temperatures. VG 22 matches the requirements of standard distribution transformers in most climate zones. For heavy-load transformers or facilities located in high-temperature environments, VG 32 is the suitable option. You may also contact our technical support team for grade recommendations based on your equipment model and operating conditions.

Do you offer custom formulation services for specific project needs?

Yes, we provide OEM and ODM custom formulation services for industrial applications. Customers can submit their required performance indicators, compliance standards and application scenarios, and our R&D team will develop targeted formulations and provide sample testing support accordingly.

What compliance certifications does this transformer oil hold?

The MX Series transformer oil has passed SGS performance testing and conforms to RoHS environmental protection standards. The production facility operates under an ISO 9001 quality management system, with batch testing conducted before delivery to ensure product consistency.
