WishPower is a global supplier of electrical insulation components and lightning protection systems. With advanced pultrusion and molding facilities, we specialize in manufacturing FRP winding cores, insulator rods, and surge arrester accessories for power grids, substations, and renewable energy systems.
The composite insulation winding core is a key internal component in metal oxide surge arresters (MOA). It is typically made from FRP (Fiber Reinforced Polymer) with excellent electrical insulation, mechanical strength, and dimensional stability. The core is surface-treated with epoxy resin or silicone coating, ensuring safe operation under high-voltage and harsh environmental conditions.
This component is suitable for use in surge arresters rated from 10kV to 220kV and can be fully customized in length, diameter, and end-machining to match specific design requirements.
