About Product
Highlight
RUBLS-EPDM a series of open-ended, tubular rubber sleeves, which are factory expanded and assembled onto a removable core. They are supplied for field installation in this pre-stretched condition. The core is removed after the tube has been positioned for installation over an in line connection, terminal lug, etc., allowing the tube to shrink and form a waterproof seal. The insulation tube is made of EPDM rubber, which contains no chlorides or sulphurs. Various diameter sizes will cover a range of 1000 volt cables, copper and aluminum conductors

Volsun RUBLS-EPDM UV Resistant EPDM cold shrink tube for low voltage power cable joint protection 600V~1KV is an engineered solution designed to deliver reliable sealing, durable insulation, and rapid installation for low voltage cable systems. The Volsun RUBLS-EPDM cold shrink tube product line focuses on simplicity and performance, combining EPDM UV resistant elastomer formulation with an optimized cold shrink tube construction to meet the demands of modern utility, industrial, and commercial power networks. This cold shrink tube delivers trusted low voltage cable joint protection while supporting a wide range of field applications and ensuring long-term service life in outdoor and indoor environments.
Key Features and Material Advantages
The core material in this design is EPDM UV resistant rubber, specifically formulated to provide exceptional resistance to ultraviolet radiation, ozone, moisture, and temperature variation. EPDM UV resistant properties protect the cold shrink tube from cracking, hardening, and degradation under prolonged sun exposure, making it ideal for exposed locations. As a cold shrink tube, the product is pre-expanded onto a removable core so that installers can achieve consistent sealing and insulation without heat sources or complex tools. The cold shrink tube construction enables quick deployment and reliable low voltage cable joint protection across a spectrum of site conditions.
Mechanical resilience is a major benefit of the EPDM UV resistant compound. The rubber formulation maintains elasticity and compressive recovery to sustain a robust seal around cable joints over time. The EPDM UV resistant material offers superior dielectric behavior for low voltage applications, providing safety and performance in the 600V-1KV power cable solution range. Combined with precise molding and quality control, Volsun RUBLS-EPDM cold shrink tube products resist abrasion and mechanical stress while forming an effective environmental barrier.
Installation and Field Application
The Volsun RUBLS-EPDM cold shrink tube simplifies installation for technicians and reduces labor time. The installer merely slides the pre-expanded cold shrink tube over the prepared cable joint and removes the inner core, allowing the EPDM UV resistant sleeve to contract tightly around conductors, connectors, and splices. The cold shrink tube design removes the need for torches, ovens, or adhesive curing; this enables safer, faster work in confined spaces and live-service scenarios that are typical for low voltage cable joint protection tasks.
Applications for these cold shrink tube solutions include residential and commercial distribution networks, outdoor feeder lines, underground-to-overhead transitions, street lighting circuits, and other low voltage infrastructure where quick, reliable sealing is needed. The 600V-1KV power cable solution rating ensures compatibility with a broad range of low voltage systems and simplifies inventory management for utilities and contractors who require versatile products for cable joint protection.
Innovation and Engineering
Volsun leverages its long-standing polymer research and development capability to optimize the EPDM UV resistant compound and the cold shrink tube manufacturing process. Formulation innovations enhance thermal stability, oxidative resistance, and long-term elasticity to extend service life. Production methods yield consistent wall thickness, uniform compression set behavior, and tight dimensional tolerances to ensure predictable performance when deployed. These engineering improvements directly translate into more dependable low voltage cable joint protection and fewer field failures.
The product’s UV resistant EPDM compound is tailored to resist common aging mechanisms, including UV embrittlement and ozone cracking. By addressing these degradation modes through material science, Volsun ensures that each cold shrink tube retains insulating properties and mechanical integrity throughout the rated lifespan. This focus on material longevity reduces maintenance cycles and lifecycle costs for low voltage networks.
Technical Performance and Standards
Designed for 600V-1KV power cable solution requirements, the Volsun RUBLS-EPDM cold shrink tube provides reliable dielectric strength and environmental sealing appropriate for low voltage distribution systems. The EPDM UV resistant composition ensures stable electrical insulation characteristics under varying ambient conditions. The cold shrink tube can be specified for different diameters and lengths to match conductor sizes and splice geometries while maintaining consistent low voltage cable joint protection.
Quality systems and manufacturing excellence underpin performance. Volsun’s production follows robust certification and quality control procedures to deliver reproducible properties such as tensile strength, elongation, compression set, and dielectric withstand. These quality attributes are essential for a cold shrink tube intended to deliver consistent protection for low voltage cable joints across diverse installation scenarios.
Safety, Efficiency, and Cost Benefits
Cold shrink tube solutions like the Volsun RUBLS-EPDM product reduce installation risk by eliminating open flames and hot-work requirements that are common with heat-shrink methods. The quick-fit approach shortens installation times, reduces labor costs, and minimizes downtime for energized circuits. The EPDM UV resistant material lowers the likelihood of premature failure due to environmental exposure, thereby lowering long-term replacement and maintenance expenses for low voltage cable joint protection.
By offering a product tuned for the 600V-1KV power cable solution range, Volsun helps installers and asset owners standardize on a dependable protective sleeve that performs across many low voltage use cases. Fewer part numbers, simplified training, and faster installations translate to operational efficiencies and improved project timelines.
