PART-C (DISMANTLING WORKS)

Dismantling of 03 (Three) phases existing ACSR Zebra conductor all hardware fiting and conductor accessories e.g. Armour rod, vibration dampers, insulator strings etc of existing line and re-rolling of dismantled conductor are empty drum on re-use safety transportation of all removed material to UPPTCL store. (Quantity has been taken double for 06 phase)

De-stringing of 24 Fibre OPGW cable along with hardware fitting,joint box and its proper rolling

Dismantling and Stacking of 220 KV Double Circuit towers after cutting of bolt with all safety and precaution along with associated works. Dismantling of the tower is done piece by piece in a safe manner by removing the tack welding / punching, un-fastening the bolts &nuts in a systematic manner, the members so dismantled shall have to be in such a condition that the same can be re-used in future. To the maximum possible extent as cutting / cutting shall have to be avoided. Similarly, while de-stringing the materials are to be removed carefully without damage to the materials (Conductor/ Insulators / Hardware fittings etc.). The removed/released materials are to be re-used to the extent possible.
