WishPower is a leading exporter and manufacturer of power system components including surge arresters, insulators, transformers, and their internal accessories. We specialize in producing insulation inner cores for surge arresters, using high-strength FRP (fiber-reinforced epoxy resin) materials suitable for high-voltage applications.
With precise production capabilities and strict quality control, we provide custom sizes and structures for clients worldwide, supporting OEM and ODM cooperation.
The insulation inner core is the critical structural support inside a metal oxide surge arrester (MOA). It holds zinc oxide varistors in place and ensures the mechanical and dielectric integrity of the overall assembly.
WishPower produces high-performance FRP rods in various diameters and lengths, tailored to different voltage levels from 10kV to 220kV. The rods are manufactured using epoxy resin reinforced with glass fiber for superior electrical and mechanical performance.
