DESCRIPTION

Product Overview:

Railway Insulators for Catenary Systems USA are essential components in overhead contact line systems, ensuring reliable electrical isolation in electrified rail networks. WishPower supplies a full range of composite insulators specifically designed for North American railway standards, including ANSI C29 and AREMA RP-8, widely used in 25kV and 2×25kV catenary systems.

Our insulators are made of high-quality HTV silicone rubber, ECR fiberglass core rods, and corrosion-resistant hot-dip galvanized fittings. Designed with modular construction, these insulators can be customized to match different mechanical loads, creepage distances, and installation types.
