Mahavir Transmission Limited has been able to indigenously develop advanced Carbon Composite Core Type HTLS Conductor under the brand name of “ACER” in June 2023.
We have launched this special product for the power industry. It is the first time ever that such a product has been developed indigenously; which will fulfil the need of efficient, sustainable transmission and distribution infrastructure throughout the country.
Our Plant is equipped with all modern facilities in respect of machinery and testing equipment required to manufacture this special type of conductor. Moreover, our Carbon Core Partner is qualified according to ASTM B987 from internationally recognized laboratories for the usages in HTLS Conductor which is Type Tested as per ASTM B987.
A fully equipped composite testing laboratory is located at our Carbon Core Partner’s Plant which provides end to end testing required for the product. We, Mahavir Transmission Limited continue to focus on nation building and our vision is aligned with the vision of India’s Honourable Prime Minister Sh. Narendra Modi to make India into Atmanirbhar Bharat.
1. 100% Indigenous Product.
2. Composite Core having high strength.
3. Low Coefficient of Linear Expansion.
4. High Operating Temperature.
5. Low Density.
