A polymer insulator manufacturing plant specializes in producing composite insulators used for high-voltage transmission and distribution systems. These insulators consist of a fiberglass core rod, silicone rubber housing, and metal end fittings. Compared to traditional ceramic insulators, polymer insulators are lighter, more durable, and highly resistant to pollution and weathering.
WishPower operates a modern manufacturing plant equipped with automated injection systems, vulcanization equipment, and mechanical test labs. Our products comply with IEC 61109 and GB standards, covering voltage ratings from 10kV to 220kV with various structural and dimensional customization options.
