In the field of overhead power distribution, the safe operation of transmission lines is crucial, and insulation protection is a crucial component in ensuring line safety. Traditional insulation protection methods often suffer from drawbacks such as inconvenient installation and poor weather resistance, making them unable to meet the demands of modern power systems. Volsun self-locking overhead line insulation sleeves, with their convenient "roll-and-protect" design and excellent weather resistance, provide an efficient and reliable solution for transmission line protection.

 
Volsun self-locking overhead line insulation sleeves are made of high-quality silicone rubber, capable of maintaining stable performance in extreme environments. They remain flexible and crack-free at temperatures as low as -50°C and resist cracking at temperatures as high as 155°C, making them ideal for outdoor environments of both extreme cold and high temperatures. Furthermore, they offer excellent weather resistance, anti-aging, and corrosion resistance, as well as hydrophobicity and hydrophobic migration properties. Even with long-term outdoor use, their performance remains unchanged, extending their service life far beyond that of ordinary sleeves.
 
Volsun self-locking overhead line covers feature a unique self-wrap design that allows for a tight fit around bare conductors and cables, requiring no tools; they can be manually wrapped. This design reduces installation time by 70% compared to traditional sleeves. It is particularly suitable for power outage-sensitive locations such as substations and high-speed rail lines, significantly reducing the economic losses caused by power outages.
 
In addition, this self-locking insulation sleeve excels in electrical safety, mechanical toughness, and customization options. Its electrical strength reaches up to 20kV/mm, and its volume resistivity exceeds 1×10¹⁴Ω cm, effectively preventing leakage risks and increasing the safe distance between bare cables and objects. With a tensile strength exceeding 4.0MPa and an elongation at break exceeding 200%, it is flexible and bend-resistant, ensuring no damage to cables or conductors during installation. Available in iron red and gray, these colors can be customized upon request.
 
Volsun self-locking overhead line insulation sleeves meet or exceed national standards for all performance indicators, including electrical strength, tensile strength, elongation at break, and low-temperature flexibility. These data fully demonstrate its superior protection capabilities, making it suitable for a variety of applications, including substation aluminum stranded wire, distribution line branches, and overhead cables.
 
Choosing Volsun means choosing a professional and reliable insulation protection solution for your overhead lines!
