MIDEL 7131 is a fire safe, synthetic ester-based transformer fluid that has been successfully serving the global market for over 30 years. Users favor the fluid for a range of applications because of its flexibility, reliability, high performance and asset life extension.
MIDEL 7131 provides a safe alternative to traditional fluid and dry-type transformers. It offers high temperature performance, increased fire safety, greater environmental protection and superior moisture tolerance. The fluid has been used in thousands of projects, many of which are located in demanding or critical areas such as offshore and underground.
The transformer industry recently reported the failure of multiple large units due to the presence of corrosive sulfur. MIDEL 7131 has been tested by independent laboratories to ASTM D1275 B, Standard Test Method for Corrosive Sulfur in Electrical Insulating Oils and IEC 62535, Insulating liquids – Test method for detection of potentially corrosive sulfur in used and unused insulating oil. It was found to be Non-Corrosive.
In addition, the fluid is RoHS compliant and does not contain the flame retardants PBB and PBDE, nor is it formulated using lead, cadmium, mercury or hexavalent chromium. The concentrations of these heavy metal contents are all below 1ppm.
MIDEL 7131 filled transformers are available from all major transformer manufacturers. The fluid is compatible with standard transformer insulating materials, components, and with fluid processing equipment and procedures. Midel is suitable for a wide range of transformer applications, including sealed and free-breathing transformers located indoors or outside.
The company says the benefits of its MIDEL 7131 include:
· UL Classified
· FM Global Approved Less Flammable Transformer Fluid
· ATEX Certification
· REACH Registered
· RoHS compliance
