UV Resistant Insulated Cable Insulation Waterproof EPDM Cold Shrink Tubing Cold Shrink Tube

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
Compared with the heat shrink tube, it has better resistance to weather and ultraviolet aging, and does not brittle after long-term use
Compared with silicone rubber cold shrinkable pipe, more puncture resistance, wear resistance, acid and alkali resistance
It can synchronize thermal expansion and contraction with the workpiece in the harsh environment, without producing gaps and sealing tightly
Even in a state of wind sway, it can still breathe synchronously with the workpiece, and the sealing effect remains excellent
Suitable for power cables below 1KV and a wide range of specification, and can be used in indoors and outdoors, overhead, water or buried occasions
Strong toughness and rebound resilience, maintaining a constant radial pressure and providing a tight seal for the cable in the long run
Easy installation without heating or special tools and no need for hot melt adhesive or tape to strengthen the seal at the joint
Standard color: Black

Volsun presents an advanced solution for durable cable protection: the UV Resistant Insulated Cable Insulation Waterproof EPDM Cold Shrink Tubing Cold Shrink Tube. Engineered for demanding environments, this EPDM cold shrink tube offers superior performance where longevity, reliability, and ease of installation are critical. Designed to meet modern industry needs, the EPDM cold shrink tube delivers a combination of UV resistant insulated tubing, waterproof cable insulation, and cold shrink waterproofing that ensures cables and terminations remain protected against environmental and mechanical stresses

Product Overview and Key Features

The EPDM cold shrink tube from Volsun is a pre-expanded elastomeric sleeve manufactured from high-grade EPDM rubber compounds. As an EPDM cold shrink tube, it is formulated specifically for UV resistant insulated tubing applications to prevent degradation from prolonged sunlight exposure. The combination of EPDM material and careful compound formulation provides excellent resistance to ozone, ultraviolet rays, weathering, and aging. This EPDM cold shrink tube maintains flexibility and elasticity over a wide temperature range, ensuring reliable sealing and insulation performance in outdoor and indoor installations alike

Waterproof cable insulation is a primary objective of this EPDM cold shrink tube design. Upon deployment, the EPDM cold shrink tube recovers to its original size without heat, creating immediate compression to form a tight, durable seal around connectors, splices, and terminations. This cold shrink waterproofing action eliminates the need for torches, ovens, or heating tools, enabling rapid, safe, and clean installation. The cold shrink waterproofing capability makes the EPDM cold shrink tube an ideal choice where quick deployment and minimal on-site equipment are required

Applications and Use Cases

Volsun’s EPDM cold shrink tube suits a broad range of industries and application scenarios. As UV resistant insulated tubing, it provides robust protection for power distribution networks, telecommunications lines, and outdoor cable assemblies subjected to direct sunlight. The UV resistant insulated tubing properties ensure that outdoor installations maintain mechanical integrity and insulation resistance over long service lives

In utility and infrastructure projects, the EPDM cold shrink tube functions as reliable waterproof cable insulation for jointing and termination of low-voltage, medium-voltage, and communication cables. Its cold shrink waterproofing features are particularly advantageous for field technicians working in confined spaces, elevated locations, or environments where use of heat sources is unsafe or impractical. In automotive and electric vehicle applications, the EPDM cold shrink tube offers resilient insulation protection against moisture ingress and environmental exposure, meeting the demanding vibration and thermal cycles of vehicle systems

Key technical applications include:

- Outdoor aerial and underground cable terminations using UV resistant insulated tubing to prevent solar degradation

- Telecom splice protection where waterproof cable insulation is critical for signal integrity and longevity

- Renewable energy installations, including PV arrays and wind farms, where cold shrink waterproofing facilitates safe, fast sealing of cable ends

- Industrial and marine electrical systems that require durable EPDM cold shrink tube solutions to resist salt spray, humidity, and mechanical wear

Innovation and Technical Advantages

Volsun’s EPDM cold shrink tube integrates material science expertise and production experience to deliver multiple technical benefits. The EPDM cold shrink tube leverages high-performance EPDM formulations that combine excellent dielectric properties with robust environmental resistance. As UV resistant insulated tubing, it avoids the embrittlement and cracking that typical elastomers can suffer under UV stress, maintaining a continuous insulating barrier

The cold shrink waterproofing mechanism provides a permanent seal that resists water intrusion and moisture migration. Because the EPDM cold shrink tube recovers elastically without heating, installation errors due to uneven heating are eliminated, reducing rework and enhancing field reliability. The volumetric memory and recovery force of the EPDM cold shrink tube ensure consistent compression and long-term sealing pressure, preserving waterproof cable insulation integrity even under thermal cycling and mechanical vibration

Another significant advantage is the EPDM cold shrink tube’s compatibility with a variety of substrates and cable designs. The material adheres and conforms to irregular shapes of connectors and splices, delivering comprehensive coverage and eliminating air gaps that can lead to water ingress or corona discharge in high-voltage applications. As UV resistant insulated tubing, it is also resistant to common chemicals and environmental contaminants, further extending operational life in harsh settings

Installation Efficiency and Safety

Cold shrink waterproofing with Volsun’s EPDM cold shrink tube dramatically simplifies field operations. Technicians expand the EPDM cold shrink tube onto a removable core, position it over the prepared splice or termination, and then remove the core to allow the sleeve to shrink into place. This process requires no flame, hot air, or thermal curing, reducing fire risk and the need for specialized heating equipment. The EPDM cold shrink tube’s straightforward installation lowers labor time and costs while improving safety on site

Quality Assurance and Compliance

Volsun’s manufacturing and quality systems ensure that the EPDM cold shrink tube meets stringent performance standards. As a National High-tech Enterprise with extensive R&D capability, Volsun conducts rigorous testing for UV resistance, dielectric strength, water ingress protection, thermal stability, and mechanical durability. The EPDM cold shrink tube is part of a product suite that supports OEM and OEM/ODM needs across global markets, ensuring consistent quality and traceability for large-scale deployments
