Control of the Electric Field Distribution in the Connectors of the Cables

The paper presents the analysis and control of electrical field in the mechanical connectors of the high-voltage (HV) cables. In the cable terminals a field enhancement occurs because the core has a sharp edge and the shield is interrupted. A mechanical connector links the cables and controls the electric field using special materials to ensure a homogeneous potential distribution. We present the analysis of the electric field in connectors and the control of the electrical field using Raychem technology. A semiconductor shield and a control tube can optimise the field distribution in cable connectors and terminals.
