A composite long rod insulator is a type of insulator used in high-voltage electrical power systems. It is designed to provide insulation and support for power transmission lines and electrical apparatus. Composite long rod insulators are primarily used in suspension strings in straight-line supports and as tension strings in anchor towers and dead-end towers. They are also used in the jumpers or portals of outdoor substations. Composite long rod insulators are made from a combination of materials, typically fiberglass reinforced with epoxy resin. The composite materials used in these insulators offer several advantages over traditional ceramic or glass insulators. Some of the …
