The Heavy Wall Heat Shrink Tube (MV) is designed for medium voltage applications, offering superior mechanical protection and environmental sealing. Made from high-quality polyolefin, it protects cables from damage, moisture, and environmental factors.
With a 3:1 shrink ratio, it fits a wide range of cable sizes and ensures a secure, watertight seal with its thermoplastic adhesive liner. Operating at -45°C to 110°C, it performs reliably in harsh conditions, including underground and submersible installations.
Our Heavy Wall Heat Shrink Tube (MV) is engineered for exceptional performance in demanding medium voltage applications. Designed to meet the rigorous requirements of underground cable installations, submersible environments, and direct burial conditions, these tubes offer superior mechanical protection and environmental sealing. These heat shrink tubes provide reliable insulation and stress relief, safeguarding your electrical systems even under the most challenging conditions.
Manufactured from high-quality polyolefin material, the Heavy Wall Heat Shrink Tube is specifically designed to protect cables from mechanical damage, moisture, and other environmental factors that can lead to premature failure. The thermoplastic adhesive liner ensures a secure, watertight seal, enhancing the tube’s ability to provide environmental protection while maintaining high dielectric strength and electrical insulation. Whether used in underground applications, submersible environments, or exposed installations, these tubes are built to withstand harsh weather conditions, mechanical wear, and abrasion.
The 3:1 shrink ratio ensures that the tube fits a wide range of cable sizes, making it versatile for various types of installations. Its continuous operating temperature of -45°C to 110°C allows it to perform reliably in extreme conditions, while the full shrink temperature of 125°C ensures a secure and tight fit for optimal performance.
