A line guard is a protective device used to maintain proper spacing and separation between conductors. A line guard also helps shed ice and snow in cold climates to reduce the risk of overload or damage to conductors. It also has deterrents such as spikes or barriers to discourage animals from nesting on the lines. It also helps reduce the risk of equipment failure, power outages and electrical fires caused by conductor contact. They are from materials such as metal or composite materials. These help them withstand the different outdoor conditions. Line guards help maintain uninterrupted electricity supply in the tropical storms and monsoons. Common types include spacers, dampers, bird flight diverters, insulator covers and anti-icing devices. They find use in wildlife protection, mechanical protection, improving visibility and anti-icing applications.
