In a recent announcement, CTC Global said that Punjab, earlier this year, saw its first set of ACCC conductor installations.
The first two ACCC conductor installations were done by Punjab State Transmission Corporation Ltd (PSTCL), the state power transmission utility.
The two installations, both reconductoring projects, were:
- 132kV line from 220kV Verpal substation to 132kV Mall Mandi substation (12.8 ckm)
- 220kV double-circuit line from 400kV Ludhiana substation (PGCIL) to 220kV Lalton Kalan substation (5 ckm)
The Verpal – Mandi line is one of the alternate supply lines to the famous Golden Temple of Amritsar and its nearby region. PSTCL selected Casablanca size ACCC® Conductor for the 132kV line and Drake-size ACCC® Conductor for the 220kV lines.
The ACCC® Condctor has so far been installed and energized in nearly 150 projects in 21 states of India.
Gupta Power Infrastructure Ltd manufactured the ACCC® Conductor and also provided engineering and installation services. ACCC Master Installer Bapi Ghosh was onsite to provide training and support. The crews used ZECK, TESMEC and OMAC stringing equipment. TAG provided ACCC Hardware, CTC Global said.
The reconductoring project enabled the use of existing lattice structures that included crossings of the Delhi-Amritsar National highway and two electrified railway crossings. The project was completed during the winter with temperatures approaching zero degree Celsius.
Infrared Thermography Inspections were conducted after both lines were energized, both of which confirmed excellent results.
