Insulation Filling Material For Dry Tape

Application DL-500 has been developed specifically for filling high voltage bushings and insulators. Description 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. Product Name EHV Power Electronic Insulation Filling Compound Compatibility 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. Processing DL-500 is suitable for cold pumping and processing enabling cable filling without voids created by compound shrinkage.
