⭐ Conductor Name, Diameter & Technical Information — Download PDF

This PDF provides complete technical details of ACSR (Aluminium Conductor Steel Reinforced) conductors used in overhead power transmission and distribution lines. It includes all essential engineering data such as conductor type, diameter, stranding, mechanical strength, aluminium and steel area, and electrical resistance.

The document lists multiple conductor categories in both Metric and British sizes, giving engineers and buyers accurate specifications required for designing and selecting the right conductor. Each conductor’s outer diameter, wire size, weight per kilometre, and rated strength are clearly shown to support safe and efficient installation of transmission lines.

This PDF is especially useful for utilities, EPC contractors, electrical engineers, transmission line designers, and procurement teams who need verified and reliable technical information for ACSR conductors.

Cyclones Nivar & Burevi Brought Much Ease To Migrating Birds- Tamil Nadu:

Arrival of cyclones proves to be an angle with food for migrating birds. The night of November' 25th'2020 brought downpour in several coastal and northern districts of Tamil Nadu, Southern Andra Pradesh, Pondicherry along India's south east coast. Birds habitation eagerly need these rain filled cyclones to allow different microorganisms and fish to flourish and act as a major source of food for birds. Many birdwatcher elaborates that avian species take a thorough survey much before they plan for roosting, breeding as well as settling down at a place and only if they feel that the place is well equipped and secure they stopover else they disappear.

Researchers also further shares that most of the migrating birds have low frontal vision because of which they  are unable to identify powerlines obstacles and hence results in collisions. Installing Bird diverter on powerlines can be a considered as one of the best possible solution.

Karnataka High Court To State Government On GIB Survival

It was on Thursday - Karnataka High Court Questioned State Government

Will You Appoint Expert Agency To Study Habitat Of Great Indian Bustard?

The starting of year 2021 opens more possibilities / feasibility for Critically Endangered species "Great Indian Bustards - GIB. On Jan'07'2021 ,Thursday - Karnataka High Court commands State Government to submits a report by Jan'21'2021 elaborating on whether they intend to appoint a highly experienced agency like Bombay Natural History -BNHS or Wildlife Institute of India -WII to study the natural habitation of the remaining critically endangered species of "Great Indian Bustards - GIB in the state.

Bird Diverters Installation Is A Must On Power Lines- As Per NGT

The myth about the Great Indian Bustard (GIB), Powerlines and Bird Diverters is always a very sensitive point of discussion from decades. Multiple seminars, meetings and conferences were held around the globe from time to time by different wild life-saving associations, federations and other prominent governing bodies. Recently it was on 04-04-2019 ref "Original Application No. 385/2019" when Hon'ble National Green Tribunal -NGT has directed The Ministry of Environment, Forest and Climate Change - MoEF&CC to furnish a accurate report on the deaths of Great Indian Bustard within 2 months. The said report (FACTUAL REPORT ON THE GREAT INDIAN BUSTARD RECOVERY PROGRAM) was finally submitted to The Registrar of  Hon'ble National Green Tribunal -NGT  on 11-07-2019 by Deputy Inspector General MoEF&CC. After going through the facts and figures as elaborated in the above mentioned  factual report, The National Green Tribunal -NGT found that steps taken are not adequate and there continues to be high mortality of the birds.

Hence later this year on 23-12-2020{(Original Application No. 385/2019) -(IA No. 333/2020)}  The National Green Tribunal - NGT passed an order during which it has been directed that the installation of “bird diverters” on power transmission lines should be done on priority basis in order to protect the critically endangered Great Indian Bustard (GIB).

 

The Crucial Points of The National Green Tribunal -NGT Order (mitigation measures for

protection of Great Indian Bustard (GIB) are:-

 

• Bird Diverters Installation on power transmission lines is Mandatory.

• Under-grounding of transmission lines needs to be insured for all new projects by making it mandatory under the Water/Air Acts by the concerned State PCBs which may be overseen by the CPCB and the MoEF&CC.”

• Route planning

• Vane tips of the wind turbine shall be painted with orange colour to avoid bird hits

 

 

The National Green Tribunal -NGT has strictly directed the MoEF&CC/CPCB/State PCBs to take further action as per the plan suggested by the six-member committee appointed by the Tribunal itself.

In the final verdict, The Court inclined the matter by directing that all mandatory steps be taken for preserving critically endangered Great Indian Bustard (GIB) by installing bird diverters on all existing power transmission lines as suggested by the six-member Committee of the MoEF&CC. It has further directed that  Monitoring of compliance be done, preferably by the Wildlife Institute of India at least twice a year.

The Court has considered the report submitted by the Committee and directed it to finalize the proposed action plan within two months.

There has been a drastic  decline by 75% in the population of the Great Indian Bustard (GIB) since the last 3 decades. The main reason for these declines is lethal accidents /collisions with power transmission lines.

Project Great Indian Bustard (GIB) Announced by Govt of Rajasthan

Rajasthan being addressed as the continent of Great Indian Bustard-GIB. Being the largest bird of the well-known bustard family mostly prefer grasslands and scrublands as their most preferable destinations.

 

Govt. of Rajasthan came forward to rescue Great Indian Bustard by announcing a clean chit for 12 Crore -"Project - Great Indian Bustard" specifically for retrieving the population of different avian species. 

 

The Great Indian Bustard is one of the heaviest flying bird species in the world. They can weight upto 15kg and can attain height up to one meter. GIB has been observed as frequent visitors of grasslands. The latest reports confirm the population of these creatures are centric to 200 numbers only out of which 100 are expected to found in Rajasthan. The numbers very well elaborate that they are very near to extinction in the upcoming decades. This will turn Great Indian Bustard-GIB among the first Indian super species to fade off after the great Cheetah. 

As per combined survey reports the population graph of Great Indian Bustard-GIB is around 1500-2000 no's in the 1980s.GIB was found to be spread throughout the western belt of India. With uncontrolled chasing and declining prairies, their population got diminished.

Researchers suggested the installation of Bird Flight Diverter as a impactful solution in the said cause.

In July 2011 the International Union for Conservation of Nature (IUCN) declared all winged creatures as endangered species.

This alarming statement by IUCN creates a huge panic in the Union Ministry of Environment and Forests (MoEF). Immediately MOEF created an animal varieties retrieval program to save Great Indian Bustard-GIB, Lesser Florican, Bengal Florican, three of the four bustard species found in India. A year back all these three species have been indigenous to Indian fields and were found near to the edge of elimination.

 

The said retrieval program is considered to be more in books rather than to be implemented. As per some MoEF sources, the last form of the rules for the recuperation program is yet to be printed and must be communicated within the states. 

 

The tendency of the government for maintaining the nature of pendency could cost dearly for the flying species. An initiative was taken a month ago by a few influential personalities, encouraging the central clergyman of Rajasthan to start a campaign for securing winged animals. The population of winged animals in Rajasthan is extremely crucial for the said retrieval program. As per the available research, the population of these species are restricted to below 10 in different states. It's not a very easy task to lead the retrieval program with limited population.
