Raychem RPG indigenously designed Modular Cantilever System support assembly of overhead power transmission wires — i.e., catenary (1000/1200 kgf tension), contact (1000/1200 kgf tension), and droppers, to transfer overall bending, transverse and vertical loads to the mast via insulators. 

The quintessential cantilever is lightweight and robust to support the current-carrying assembly with train speed up to 250 km/h. In addition to these functional requirements, ease of maintenance, transportation, handling, and aesthetics have been considered.   

The Modular Cantilever System is available in two variants - Single Insulator (foldable design) and Two Insulator (tubular design).
