<p>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 of the insulator offers many advantages. First, the wound core presents improved mechanical characteristics. Since the resin matrix of the core and the material used to form the outer sheath are compatible, a chemical link exists 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.</p> |
