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

Whether used in industrial installations, utility distribution, construction projects, or outdoor power systems, Volsun RUBLS-EPDM offers a robust solution for modern low voltage wiring challenges
Product Overview and Key Attributes
Volsun RUBLS-EPDM is a low voltage wiring product featuring cross-linked EPDM insulation that provides outstanding fire resistant insulation and excellent resistance to severe weather conditions. This black EPDM compound is specially formulated to maintain elasticity, dielectric strength, and mechanical integrity across a wide temperature range. The cable’s design emphasizes EPDM cable safety through minimized propagation of flame, reduced smoke emission, and stable electrical parameters under thermal stress. In addition to fire resistant insulation, the product’s weather resistant power cable properties make it ideal for outdoor routing, direct burial, rooftop installations, and areas exposed to UV, ozone, and moisture
Core Technical Advantages
- Fire resistant insulation: The EPDM used in Volsun RUBLS-EPDM is optimized to provide fire resistant insulation properties, helping maintain circuit integrity during fire scenarios and minimizing the risk of short circuits caused by insulation degradation. This fire resistant insulation characteristic directly supports EPDM cable safety by slowing flame spread and protecting conductors under elevated temperatures
- Weather resistant power cable design: The outer EPDM jacket and insulation formulation impart superior weather resistance, including UV stability, ozone resistance, and water repellency. As a weather resistant power cable, Volsun RUBLS-EPDM withstands prolonged sun exposure, precipitation, and freeze-thaw cycles without cracking or hardening, ensuring dependable low voltage wiring performance in exposed conditions
- Mechanical durability: The EPDM compound delivers high tensile strength and elongation, providing resilience against abrasion, impact, and mechanical stress. This mechanical robustness enhances EPDM cable safety by reducing the likelihood of insulation breaches and subsequent electrical faults
