Abstract: A high-voltage electrical insulator formed from a modified thermoplastic insulation composition that include a thermoplastic polymer. The modified thermoplastic insulation composition undergoes radiation exposure to develop a cross-linked thermoset skin layer. The predominately thermoplastic insulation material allows for the insulator to be recyclable while the radiation-hardened skin layer improves the weatherability, durability and electrical resistivity of the exterior surface to provide a more durable and longer lasting electrical insulator.
