Stress Control Mastics also known as medium voltage cable joint tapes, electrical stress relief mastic, void-filling electrical tape, high dielectric constant yellow tape is engineered for medium voltage cable joints and terminations, providing superior electrical stress relief. Its self-fusing nature ensures seamless insulation, while its high dielectric strength and temperature resistance make it ideal for demanding environments.
