Optical Ground wire cables or OPGW cables are extensively applied by electric utility industries to protect the conductors in transmission lines from lightning. These cables also provide a path for internal telecommunication as well as that with third parties. The purpose of OPGW is to replace earth or static wires in overhead transmission lines and bear mechanical stresses caused through ice or wind. OPGW also takes care of electrical faults in transmission lines, since it charts a path to the ground without destroying the optical fibers in the cables.
Now Sterlite Power has developed immense technical knowledge and expertise in OPGW fiber optic cables and energy-efficient power conductors over the last 20 years. It has come up with a comprehensive OPGW solution by combining the major strengths of these two products. Optical fibre composite ground wire is the perfect solution for power distribution industries, equipping ultility companies with the abilities of a telecom carrier. As a leading manufacturer of OPGW cables, Sterlite offers different types as given below:
Sterlite AERIAL-LITE OPGW Cable (High Fault-Current Design) – These are offered up to 96 fibers, and are suited for super high voltage power lines. In these, steel tubes are wrapped with steel wires which can bear high strain, so as to be suitable for high fault applications.
Sterlite AERIAL-LITE OPGW Cable (Aluminum Clad Central Steel Tube ) – Available in fiber counts of up to 24, these cables consist of steel tubes clad in aluminium. They are ideal for overloaded towers owing to small diameter and lightness. They last long and are very reliable as well.
Sterlite AERIAL-LITE OPGW Cable(High Strength Design) – Designed for transmission lines above 400kV, these cables are made up of steel tubes stranded with high strain steel wires. The dual layer design is apt for applications requiring high strength, and aluminium ensures high fault rating current values.
Sterlite AERIAL-LITE OPGW Cable (Central Core tt) – The central core of these cables is an aluminium sheathed tube made of loose polymer tubes. The outer layers are a combination of ACS and AA wires with ratings as per the client’s requirement. These cables feature fiber count of up to 144 fibers and are moisture proof as well.
Sterlite AERIAL-LITE OPGW Cable (Central Steel Tube Design) – These cables come with high fiber count of 96, consist of steel tubes stranded with steel wires, and find use in high strength applications. They can bear high load and are perfect for long spans.
With advanced manufacturing units based in Uttarakhand, Dadra, Nagar Haveli and Odisha, Sterlite has carved its niche as one of the major OPGW cable suppliers in India. By using advanced technologies and following stringent quality control parameters, it has also achieved fame as a leading exporter of OPGW from India, and supplies 40 countries. Sterlite has been able to set up inter and intra state power transmission systems and develop electricity infrastructure, even in rough terrains and flood infested areas.
