Abstract
A high-voltage homogeneous co-curing composite insulator includes first and second end fittings longitudinally separated by a spacer, a resin impregnated fiber core wound onto the end fittings and onto the spacer, and an outer sheath moulded onto the fiber core. Since the resin matrix of the core and the material used to form the outer sheath each include curable resins from the same family and are, therefore, chemically compatible, a chemical link exists between these two elements. The end fittings are provided with a relatively thin wall defining a mechanical fuse.
