Product Overview
COMPAQ CSCM stress control/field graded mastic tape is engineered to ensure the long-term reliability and safety of medium and high voltage (MV/HV) cable systems. By effectively relieving electrical field stress at critical points, it minimizes the risk of insulation breakdown, partial discharge, and premature system failures.
Manufactured from a thermally stabilized polyolefin blend and reinforced with high-permittivity additives, the CSCM tape provides precise control of voltage gradients around connectors, screen cut-backs, and other stress concentrations. Its self-fusing properties allow it to conform seamlessly to irregular surfaces, ensuring void-free filling, water resistance, and superior adhesion to cable insulation and metallic components. This combination delivers a moisture-tight, mechanically stable, and electrically robust seal that performs reliably under demanding environmental and operational conditions.
By incorporating the COMPAQ CSCM Series into jointing and termination systems, utilities and installers can achieve extended service life, reduced maintenance risks, and improved performance in modern power transmission and distribution networks.
Equilibrates the electric field, reducing stress concentrations in MV/HV applications.
Bonds seamlessly to insulation and connectors, filling voids and eliminating air pockets.
Suitable for both dry and oil-filled environments.
High-permittivity additives manage electrical fields, reducing partial discharge risk.
Conforms easily to irregular shapes and varying diameters.
Maintains performance under continuous load and short-term overloads.
