ECR Rod is pultruded from glass fiber, epoxy resin and curing agent, primarily for manufacturing composite insulators.
Our ECR Rod features excellent dielectric strength, superior stress corrosion resistance, high surface resistivity, and extremely high mechanical strength and hardness, enabling a broader range of applications.
It also boasts good corrosion resistance, lightweight property, long service life, non-magnetic performance, flame retardancy, arc and tracking resistance, electromagnetic transparency, outstanding electrical insulation, low thermal conductivity and electrically non-conductive characteristic.
