Abstract: An enhanced breakdown strength dielectric material includes a base dielectric layer having first and second opposing major surfaces. A first stress mitigating layer is disposed on the first major surface of the base dielectric layer. A second stress mitigating layer disposed on the second major surface of the base dielectric layer. A volume conductivity of at least one of the first and second stress mitigating layers is at least 2 times a volume conductivity of the base dielectric layer.

Abstract: A tubular stress control article having an axial bore with a length comprises a first and innermost layer formed from an electrical stress control composition having a filler material comprising nanosilica-modified inorganic particles and a discontinuous arrangement of conductive material dispersed in an elastomeric material. At least a portion of the conductive material is in durable electrical contact with the inorganic particles. The article further comprises a second layer disposed on the first layer, the second layer comprising an electrical insulation material. The article also comprises a third layer disposed on the second layer, the third layer comprising an elastomeric stress control material. The article further comprises a fourth layer disposed on the third layer, the fourth layer comprising a track-resistant elastomeric material. Each of the first, second, third, and fourth layers are substantially continuous along the length of the axial bore.
