To improve telecom connectivity in hilly areas, Power Grid Corporation of India Limited (POWERGRID), has recently signed an agreement with Himachal Pradesh State Electricity Board Ltd. (HPSEBL) in Shimla (H.P.) for utilization of 500 Kms of OPGW Telecom network.
- Through this OPGW Network, Telecom Service providers will be able to provide uninterrupted mobile/Internet services to the people of the state.
- An optical ground wire is also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire.
- It is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and communications.
- OPGW is optical fiber composite ground wire. This cable contains a tubular structure having one or more optical fiber and surrounded by layers of aluminium and steel wires.
- This layer of aluminium and steel wires serves to connect the tower to the ground. The optical fiber within the cable is used for the high speed data telemetry between the utilities or sold to some third parties for high speed fiber interconnection between the cities.
- POWERGRID, a ‘Maharatna’ CPSE under Ministry of Power, Government of India and Central Transmission Utility (CTU) of India, is India’s principal power transmission company and also one of the largest power transmission utilities in the world.

With reference to the optical ground wire (OPGW), consider the followi...
Statement 1: It is a type of cable that is used in overhead power lines.
Statement 2: The cable contains a tubular structure having one or more optical fiber and surrounded by layers of aluminium and steel wires.
Explanation:
The optical ground wire (OPGW) is a type of cable that is used in overhead power lines. It is designed to serve a dual purpose of providing electrical grounding and fiber optic communication for the power transmission system. OPGW cables are installed on the transmission towers and provide a reliable and efficient means of communication between different power stations and substations.
The construction of OPGW cables involves a tubular structure that contains one or more optical fibers. These fibers are protected by layers of aluminum and steel wires. The aluminum wire provides electrical conductivity for grounding purposes, while the steel wire provides strength and durability to the overall cable structure.
The tubular structure of the OPGW cable allows the optical fibers to be placed in the center, surrounded by layers of aluminum and steel wires. This design ensures that the optical fibers are well-protected from external factors such as weather conditions, mechanical stresses, and electromagnetic interference.
The aluminum and steel wires also serve as the electrical conductors for grounding the power lines. The OPGW cable acts as a shield against lightning strikes by providing a low-resistance path for the current to flow into the ground, effectively protecting the power transmission system from damage.
In summary, both statements are correct. The optical ground wire (OPGW) is indeed a type of cable used in overhead power lines, and it contains a tubular structure with one or more optical fibers surrounded by layers of aluminum and steel wires.
