A volatile organic compound (VOC) is a chemical substance contained in abundance in paints, etc. that becomes a cause of air pollution as suspended particulate matter or photochemical oxidant when released into the air. As such, Kitashiba Electric is working to reduce the amount of VOCs used. When assembling a transformer, a caulking compound is used for rust prevention where surfaces meet. Previously, a cissing prevention agent was applied on the caulking compound and then a finishing paints in an exterior painting color was applied on them, because the color of the caulking compound is different from the exterior painting color.
Recently, Kitashiba Electric introduced a colored caulking compound to eliminate the cissing prevention agent and finishing paints. As a result, the amount of paints used in the typical transformer was reduced by approximately 5 kg per. Going forward, Kitashiba Electric will expand the scope of application of the colored caulking compound in an attempt to further reduce the amount of painting materials used.
