3 to 1 Shrinkratio Dual Wall Heat Shrink Tubing Featuring Low Longitudinal Shrinkage for Connector Sealing and Cable Joint Insulation

Product Description:

The dual wall heat shrink tube is an essential component in electrical insulation and protection, particularly designed to provide reliable and durable sealing for cable terminations and joints. This specialized tubing features a dual-layer construction that combines the benefits of both heat shrinkable material and an inner adhesive lining, making it an ideal choice for applications requiring superior sealing performance and environmental resistance.

One of the standout features of this dual wall heat shrink tube is its impressive shrink ratio of 3:1. This means the tubing can shrink to one-third of its original diameter when heat is applied, allowing it to conform tightly around cables, connectors, and joints of varying sizes. This high shrink ratio ensures a secure fit and excellent mechanical protection, even on irregular or uneven surfaces, which is crucial for maintaining the integrity of the cable assembly.

The dual wall adhesive heat shrink tubing is designed to operate effectively within a wide temperature range, from -45°C to 125°C. This broad temperature tolerance makes it suitable for use in various environments, including those exposed to extreme cold or heat. The tubing remains flexible and resilient under these conditions, ensuring long-lasting insulation and protection without cracking or losing adhesion.

Importantly, this dual wall heat shrink tube offers excellent oil resistance, which significantly enhances its suitability for industrial and automotive applications where exposure to oils, solvents, and other chemicals is common. The oil resistance insulation property helps prevent degradation of the tubing material, thereby extending the lifespan of the cable terminations and joints it protects. This makes it a reliable solution for harsh environments where electrical components are exposed to potentially damaging substances.

The minimum shrink temperature for this dual wall heat shrink tubing is 70°C, which means it begins to shrink and activate the adhesive lining at relatively low heat levels. This feature allows for quick and efficient installation using standard heat guns or other heating tools, reducing downtime and labor costs. The inner adhesive melts and flows upon heating, creating a watertight and airtight seal around the cable or joint, which is vital for preventing moisture ingress and corrosion.

Primarily used in PILC (Paper Insulated Lead Covered) cable terminations and joints, the dual wall heat shrink tube is tailored to meet the demanding requirements of these traditional yet critical power cables. PILC cables are known for their robustness and long service life, and using dual wall heat shrink tubing helps to maintain this reliability by providing enhanced insulation, mechanical protection, and environmental sealing at connection points where cables are most vulnerable.

In summary, the dual wall heat shrink tube is a highly versatile and effective solution for protecting electrical cable terminations and joints. Its 3:1 shrink ratio ensures a snug and secure fit, while the dual wall construction with an adhesive inner lining offers superior sealing against moisture, dust, and contaminants. The tubing’s ability to resist oils and withstand temperatures ranging from -45°C to 125°C makes it suitable for a broad spectrum of applications, especially in industrial settings and power distribution networks.

Whether you are working on PILC cable terminations, automotive wiring, or industrial electrical installations, choosing dual wall adhesive heat shrink tubing provides increased durability, enhanced insulation, and improved protection against environmental factors. Its ease of installation at a minimum shrink temperature of 70°C further adds to its practicality, making it a preferred choice for professionals seeking dependable and long-lasting cable protection solutions.
