Abstract:
1. A method of applying a silicone elastomeric coating, the method comprising spraying a silicone elastomeric material onto an electrical insulator that is for use on high-voltage power transmission lines, the silicone elastomeric material being sprayed using an applicator comprising: (a) an applicator body having a front end, a rear end, an internal bore, and a fluid inlet for receiving a supply of the silicone elastomeric material; (b) a nozzle coupled to the front end of the applicator body, the nozzle having a discharge end with a spray outlet in fluid communication with the fluid inlet via a fluid passageway, the spray outlet being shaped to spray the silicone elastomeric material along a spray axis; (c) a needle valve slidably mounted within the internal bore for movement along a longitudinal axis between a closed position for closing the fluid passageway and an open position for opening the fluid passageway so as to spray the silicone elastomeric material; and (d) an air cap coupled to the front end of the applicator body adjacent the nozzle, the air cap having at least one airflow inlet for receiving a supply of air and a plurality of airflow outlets for providing:
