Detailed Description:
Hello,
We inquire about the pricing and availability of capacitor oil that meets the specifications outlined in our Product Standard, CR 90105.
We are seeking a high-quality, unused, clear, and synthetic electrical insulating liquid for capacitor impregnation. The liquid must be stable, both chemically and physically, on heating and must be compatible with capacitor-grade PP film and other materials used in capacitor insulation systems, such as cable paper and tissue paper.
Here are some of the key technical requirements from our standard:
Physical Properties:
Specific Gravity at 27°C: 0.97 to 1.01.
Flash Point, COC °C: 130°C minimum.
Kinematic Viscosity at 37.8°C: 2.4 to 3.2 cST.
Water Content: 100 ppm maximum.
Pour Point: -50°C (this is a typical test conducted once for every 10 batches).
Chemical Properties:
Neutralisation Value (Total Acidity): 0.01 mg KOH/gm maximum.
Active Epoxide Content: 0.4 to 0.8% by weight.
Electrical Properties:
Dielectric Strength (BDV) 2.5 mm GAP: 70 kV minimum.
Dissipation Factor at 50 Hz/100 Hz at 90°C: 0.4% maximum.
Resistivity at 90°C: \bm{25 \times 10^{12}} Ohm-cm minimum.
Please note that we require a 5-liter sample drawn from each manufacturing batch to be supplied for testing at the EPL Enterprises lab.
We would appreciate it if you could provide a rate quotation for this material. We look forward to the possibility of establishing a business relationship with your company.
Thank you for your time and consideration.
