NJREC manufactures a full spectrum of glass insulators for high-voltage transmission and distribution lines. Our lineup includes standard glass insulators (e.g., U40, U70, U120, U160, U210, U300), anti-pollution insulators (U120BP/U210BP), aerodynamic glass insulators (UG70BSA/U120BLA), double shed types, and grounded circuit glass insulators (U70CN/U120C). Additional variants include line post glass insulators, pin-type insulators, and more. These insulators are primarily used for insulating, suspending, and supporting conductors, and withstanding mechanical tension on high-voltage overhead lines. With voltage compatibility from 10kV up to 1000kV, and mechanical strength ratings ranging from 40kN to 550kN, NJREC insulators are ideal for utility, substation, and grid infrastructure worldwide. Our glass insulators are made from toughened tempered glass, providing high dielectric strength, long-term durability, low aging effects, and easy visual inspection for safety assurance. Whether your project demands anti-fog glass suspension insulators, double shed types for polluted environments, or custom high-strength glass insulators, NJREC offers reliable and certified solutions for every application.
