A coating element for an electrical junction or circuit that reduces surface electric field densities. The coating element comprises a layer of plastic material laden within or in which there is dispersed conductive particles. The coating element surrounds the junction or circuit such that an inner layer or surface of the element is in contact with the outer layer or surface of the junction or circuit. The plastic material may be an elastomer, a polymer, a polyurethane or a silicone. The conductive particles may be a metal powder of aluminum or stainless steel or graphite. The resistivity of the coating element is between about 1 ohm-cm to about 100 kilohm-cm.
