The global demand for composite insulators in high voltage applications continues to grow, and since 1988, polymeric hollow core technology has proven to be a reliable, robust product. Hollow Core Insulators (HCIs) components are made of premium quality of glass-fiber reinforced resin tube, silicone rubber housing, and aluminum alloy flanges. This makes them suitable for many high voltage outdoor applications, up to 1100 kV AC and 800 kV DC.
The design and material make them lighter in weight, eliminating support structures, lowers transportation cost, and is much easier to handle. Performance wise, HCI has a proven reputation for reliability, even under extreme environments. Crucially, composite insulators are a high performance product that is cost-effective and a dependable solution.
The silicone housing that NJREC employs improves insulating behavior and protects against simultaneous moisture and pollution threats.
