Heat Shrink Closures
November 10, 2022
The engineering team at DexGreen has developed a range of high-performance heat-shrinkable closures for pressurised and unpressurised applications.
The Heat Shrink tubing is engineered for use in numerous applications, including back-end connector sealing, breakouts, and connector-to-cable transitions. It is a solid alternative to taping, molding, or potting. When heated, our heat-shrinkable closures conform to the size and shape of the substrate beneath, enabling quick and easy installation.
This established technology has been used for many years with carriers globally. It is fully tested and approved. There is a full range of pressurised and unpressurised closure available in all sizes. Airblock closure is also available., and closures are accompanied by a full range of accessories.
Inferior quality materials, coupled with Non-Compliant work practices, frequently result in the failure of Heat Shrink joints. Failure of low-quality Heat Shrink joints is caused by Moisture, Ingress, Corrosion, and Extreme Weather. As a result, this can lead to cables remaining exposed to damage, strain, dragging, flexing, and abrasion. This typically occurs during the installation stage and results in serious faults once the joint is installed.
DexGreen has developed a range of high-performance heat-shrinkable closures for pressurised and unpressurised applications in every installation configuration.
These innovative in-line heat shrink closures are fully tested and approved. Based on established, widely-used technology, DexGreen has enhanced the benefits of heat shrink applications so that users can yield the well-established advantages of heat shrink technology.
Features of the DexGreen heat shrink range include:
- Compatible with polyethylene and metal jacketed cables.
- Pre-installed valve for pressure access and measuring.
- Suitable installation locations: aerial, buried, and ducted projects.
- Suitability for use with all standard connector systems.
- Wraparound closure – suitable for both maintenance and new construction.
- End-caps and tough, highly-durable product materials for maximum durability.
Offering exceptional reliability and meeting the wide-ranging needs of a broad variety of installation and maintenance projects, DexGreen’s innovative Heat Shrink solutions are suitable for a wide range of skill levels.
With highly resilient Heat Shrink joints to suit all cable configurations (pressurised and unpressurised, in all sizes, etc.), DexGreen has ensured the successful completion of countless underground, aerial and ducted projects throughout the networks of the world’s leading telecom carriers.
Importantly, an airblock closure solution is available; plus, DexGreen provides a full range of accessories.
