Gupta Power Infrastructure, in alliance with Bhutan Power Corporation Limited, has successfully completed the installation of the latter’s first two ACCC® Conductor installations in Bhutan — according to the reports.
The 66 kV Semtokha to Hongtsho transmission line and the 66 kV Semtokha to Dechencholing line used 242 kcmil (122.7 mm2) Silvassa size ACCC® Conductor to replace ACSR Dog size conductor initially installed in 1985. Existing steel lattice structures were used without modification. Spans included highway crossings up to 712 meters.
ACCC® Conductor for the projects were supplied by Gupta Power and ACCC® Hardware was supplied by TAG. The ACCC Conductor’s composite core was produced by CTC at its Global headquarters in Irvine, California.
Bhutan Power Corporation’s projects enabled a substantial capacity increase to support the new 33/66 kV substation at Hongtsho. Hitesh Mundhada, Vice President CTC Global – South Asia stated: “The mountainous terrain made it extremely difficult to bring in men, materials and equipment, and elevation differences between adjacent towers made it very challenging for conductor pulling, but the projects were completed successfully without issue.”
