XIAMETER® CTG-1890 Protective Coating Gray is a general purpose coating material providing extra protection to such electrical equipment as:
• Motor stator windings – Protects insulated motor windings from: dust occurring in quarries, cement plants, mines, taconite mills; moisture in dairies, food processing plants, paper mills, bottling plants; chemicals in tanneries, packing and dye houses, fertilizer plants
Bus bars – Exposed bus bars can be quickly coated by brushing on XIAMETER CTG- 1890 Protective Coating Gray
• Splices and connectors – Provides insulated splices with additional protection against ultraviolet radiation, water and moisture; exposed connections covered with this coating are protected against contaminants and corrosive fumes
• Transformers – Insulates the tops of distribution transformers and prevents short circuits caused by animals bridging between exposed terminals and the grounded tanks; also prevents short circuiting caused by birds or animals on other equipment
• Wooden pole tops and insulator pins – Prevents pole-top damage resulting from weathering and moisture when used to seal the end-grains of wooden poles; applied to wooden insulator pins and crossarms; prevents damage due to current tracking and subsequent burning
