Overhead Line Insulation Sleeve
Live installation Lightweight Anti-tracking
Weather Resistance
Superior UV and Abrasion Resistance
Localized Installation
•Designed to provide reliable protecting for different cables such as power electrical wire and meshwork of tunnel.
•Suitable for single-phase 50Hz/25KV alternating current. •It can provide high resistance to tracking and arcing, as well as to enhance the insulation properties of cable from 1KV to 35KV. Without heating and easy to install and economic. •Used for railway contact network overhead line system, improve insulating performance and prevent electrical outages caused by incidental contact from tree branches or wildlife.
•If overhead lines get across tress or are close to trees or buildings, it may lead to electrical outages caused by incidental contact from tree branches or wildlife. Overhead Line Insulation Sleeves can provide unique insulating protection solution for those kind of problems.
