ATD (Auto Tensioning Device)

Light weight spring ATD for 25 KV line - 20KN and 24 KN. In an electric rail system, power is supplied by overhead lines that run along the entire length of the railway tracks. This power is transferred to the train by means of the pantograph which is a current collector mounted on top of the locomotive. ATD provides a mechanism for automatic tensioning of OHE lines to ensure smooth collection of current by moving pantograph. Tensioning is needed on the contact lines due to variation in their lengths. Contact lines are primarily made from copper-based alloys prone to expansion and contraction due to variations in atmospheric temperatures. The absence of tensioning causes overhead lines to sag or tighten, leading to pantograph entanglement or snapping of overhead equipment (OHE) lines. We have introduced an indigenous spring ATD which is very light in weight and can cater to the load requirement upto 30 KN.

Heat Shrink Medium Voltage Joints

Medium Voltage Heat Shrink Joints-Conventional and next generation. Raychem developed highly specialized polymers for heat shrink joints suitable for plastic and paper cables upto 36 kV. For transition joints, a special oil barrier tubing is used to transform draining oil (MI) and non-draining oil (MIND) paper insulated cable into quasi-polymeric insulated cable with a radial field. The conventional design developed in 1980 was based on multiple layer tubing concept providing insulation and stress functions. The latest developed heat shrink joint is a single tubing (triple layer co-extruded) of adequate thickness which provides insulation for a particular voltage range.

MCS (Modular Cantilever System)

MCS for 25 KV high speed requirements - 20 KN and 24 KN. Raychem Indigenous Modular Cantilever System is designed to support the assembly of overhead power transmission wires — i.e., catenary (1000/1200 kgf tension), contact (1000/1200 kgf tension), and droppers — to transfer the overall bending, transverse, and vertical loads to the mast via insulators. The quintessential cantilever is lightweight and robust enough to support the current-carrying assembly for semi-high speed and high-speed trains up to 250 km/h. In addition to these functional requirements, ease of maintenance, transportation, handling, and aesthetics have been considered.

SNS (Short Neutral Section)

Short Neutral Section (PTFE) for 25 KV line, The utility power supply system expects equal loading on all phases. Traction power system works on single phase 25kV traction system. It now becomes important to use all the three phases equally and convert them into one phase traction supply. This is achieved by feeding single phase supply to the adjacent traction substation which is separated by a neutral section. Each feed covers a distance of about 30-40Km feeding all the trains in that zone. Short Neutral sections are dead zones in the overhead line, used for isolating or separating different sections of the overhead electricity transmission line &also to provide smooth transition of pantograph from one section to another. To ensure strong Electrification drive, wear and tear nature of existing PTFE SNS needs a complete relook and design. Raychem RPG has introduced indigenous Short Neutral section for 25 KV line which is a moving roller-based technology and also, an alternative retrofit system for easy replacement of linings. A system which can eliminate the periodic maintenance and servicing issues.
