  • Semiconductive coating and application process for shielded elastomeric electrical cable accessories
    Patent number: 7090796
    Abstract: A method is provided for manufacturing a semiconductive insulating shield for an electrical cable accessory. The method includes providing a substrate having a desired contour in relation to the electrical cable accessory. The substrate is then coated with an elastomeric semiconductive material to form a coated substrate. An elastomeric insulating dielectric material is then molded around the coated substrate, and the elastomeric semiconductive material and elastomeric insulating dielectric material are cured by applying heat and pressure sufficient to transfer the elastomeric semiconductive material to the elastomeric insulating dielectric material by chemical bonding.
    Type: Grant
