A high-voltage composite insulator and method are described herein. The 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 mould onto the fiber core. The construction o f the insulator offers many advantages. First, the wound core presents improve d mechanical characteristics. Since the resin matrix of the core and the material used to form the outer sheath are compatible, a chemical link exist s between these two elements. Finally, the end fittings are provided with a relatively thin wall defining a mechanical fuse. A method for making such an insulator where both the core and the outer sheath are co-cured is also described herein.
