Electrical insulating oil

Basic Identifiers

ID Type BO
6747 transformer mineral

Description

Shell DIALA® Oils A & AX meet standard specifications required by both ANSI/ASTM D 3487 and NEMA TR-P8-1975 for domestic electrical oil applications. These products have high electrical resistance and are thermally and oxidatively stable. Two oils, designated Type I and Type II, are covered in these specifications. Type I oil is intended for use where normal oxidation resistance is required. Type II oil is for more severe service applications requiring greater oxidation resistance.

ASTM D341 Viscosity Calculator

You may calculate the viscosity of the oil at various temperatures based on ASTM D341. This uses the two sets of calibration data that we already have in order to calculate the viscosity at any temperature. You may input multiple temperatures at once, seperated by comma.
