NU-SLEEVE HV-565 is a heavy wall silicone-coated fiberglass sleeving offering high heat resistance up to +200°C, excellent abrasion resistance, and strong adhesion. It resists fray and coating fracture, making it ideal for high-stress applications. The sleeving provides good resistance to acids and alkalis, though some swelling may occur with certain solvents. Commonly used for terminal and lead insulation, as well as high-current dry transformers, it also delivers high dielectric voltage ratings.
