A coating material dispensing and charging system comprises first electrical conductors extending between first electrically non-conductive supporting members, a power supply coupled across the first conductors and articles to be coated to maintain a high magnitude electrostatic potential difference across a space defined between the first conductors and the articles, a dispenser for dispensing the coating material into the space, and a supply of coating material for the dispenser. The first electrical conductors comprise electrically conductive filaments surrounded by electrically non-conductive sheaths.
