A hybrid single or multilayer composite reinforcement system is disclosed. The system is configured to install or apply around the existing power transmission lines, for example, ACSR transmission lines for increasing ampacity and also decreasing sag of the power transmission lines. The hybrid composite system comprises a first layer, a second layer, and a composite core as a structural reinforcement component. The first layer and second layer are formed using a fiber reinforced resin composite material, comprising a basalt fiber and the structural reinforcement component is a carbon fiber. The composite core is disposed between the first layer and second layer. Further, the first layer and second layer are cured, thereby making the multilayer hybrid composite reinforcement system. The composite core, comprising for example carbon fiber, provides structural strength for the hybrid composite system. The system is novel, lightweight, fast and easy to install, long-lasting, reliable, environmentally friendly, and cost-effective.

An isolator device is provided comprising a body of first dielectric material between the first and second conductors, such as primary and secondary coils of a micro-transformer. A region of second dielectric material is provided between the body of first dielectric material and at least one of the first and second electrodes, wherein the second dielectric material has a higher relative permittivity than the first dielectric material. This provides enhances ability to withstand the Electric fields generated at the edge of a conductor. The body of the first dielectric can be tapered to provide stress relief to prevent the second dielectric material developing stress cracks.
