How Does PE Overhead Line Cover Revolutionize Overhead Line Insulation Protection?

We know that insulation protection for overhead transmission and distribution lines is a crucial component of the entire power system. So, how can we effectively protect bare overhead conductors? Volsun PE overhead line cover is the answer.

The core advantages of Volsun PE overhead line cover lie in its superior material properties and user-friendly design. 

First, its use of high-quality radiation-cross-linked polyolefin as a base material gives it exceptional environmental adaptability. Whether in winter temperatures as low as -50°C or as high as 125°C, it maintains stable physical properties, resisting brittle cracking at low temperatures and aging at high temperatures, ensuring long-term, reliable operation in a variety of extreme climates. Furthermore, its excellent weather and corrosion resistance means it effectively resists UV rays, moisture, and chemical damage, significantly extending the service life of outdoor cables.

Second, Volsun PE overhead line cover sleeve offers revolutionary convenience during installation. It eliminates the complex processes of traditional sheathing, such as hot work and gluing, and adopts a unique snap-fit design. Construction workers simply slide the sheath onto the cable and snap it shut, requiring no tools or materials. This design not only reduces cable installation time by over 50%, but more importantly, it allows for "no-hot-fire" operations, making it particularly suitable for safety-critical fire-prohibited areas such as substations and high-speed rail tunnels. For projects like urban power grid reconstruction, which require meticulously planned power outages, rapid installation minimizes the economic losses and social impact of outages.

Furthermore, Volsun PE overhead line cover excels in safety. It boasts excellent insulation properties, achieving a breakdown strength exceeding 25kV/mm for low-voltage lines of 10kV and below, and as high as 40kV/mm for high-voltage lines of 35kV and above. This effectively isolates leakage risks and ensures the safety of personnel and equipment. The product also combines high flexibility with high strength, boasting a tensile strength exceeding 9 MPa and an elongation at break of up to 550%. This means it can easily adapt to cable bends and withstand unexpected compression during construction and maintenance, providing a sturdy, form-fitting "armor" for conductors and cables.

Thanks to its comprehensive performance, Volsun PE overhead line cover has a wide range of applications, from urban distribution networks and residential cable branch boxes to substations and high-voltage transmission lines, cable tunnels in high-speed rail and subway systems, and power lines in various industrial plants. Whether in standard sizes from Ø14 to Ø38 or customizable models for specialized applications, it perfectly adapts to provide reliable protection for cables of varying voltage levels and environments.
