TECHNICAL DATA SHEET
DL-500 has been developed specifically for filling high voltage bushings and insulators.
DL-500 is a thixotropic, non-sticky water-blocking compound with a very low density. It is based on highly refined white oil and exhibits high compressibility for improved filling and low acidity to prevent corrosion. DL-500 has excellent electrical strength and low permittivity with good oxidation resistance.
EHV Power Electronic Insulation Filling Compound
DL-500 is compatible with most polymers, resins, bushing cores and adhesives. Tests on typical polymers show minimal reaction but it is recommended that compatibility tests are made with all materials likely to come into contact with the gel.
DL-500 is suitable for cold pumping and processing enabling cable filling without voids created by compound shrinkage.
