Our premium Medium Voltage Tape is a high-performance insulating solution specifically engineered for solid dielectric cables ranging from 600V to 69kV. Designed to meet rigorous industrial standards, this tape serves as the primary insulation for stress cones and provides essential jacket restoration for intermediate joints and terminals, ensuring maximum electrical stability and safety in high-voltage environments.
Beyond primary insulation, this versatile rubber tape is ideal for creating moisture-proof seals for critical electrical connections, busbar insulation, and cable end seals. To achieve optimal performance, we recommend stretching the tape to 3/4 of its original width during application and finishing with a layer of PVC electrical tape for enhanced mechanical protection against external wear and tear.
