Replacing broken/damaged LT/HT PCC poles (9/11/13 m) & erecting new PCC pole (9/11/13 m) in mid-span to raise low-hanging conductors / AB cable to safe ground clearance - loading from store (up to 100 KM distance from site), carriage to site, return back the scrap to store again, pit digging (depth & grouting as per standard line-construction practice), erection, fixing clamp/cross- arm/insulator, sagging of conductors to safe ground clearance & restoring supply. All grouting material by contractor.

Repair of rust-damaged ST poles (9/11/13 m) near ground by welding additional channel/angle/iron strip of approved section to restore strength. Channel/angle/strip by contractor

Pulling & tightening of loose conductor/AB cable/new conductor (LT & HT) per span, maintaining safe ground clearance as per CEA Safety Regulations.

Straightening of tilted poles by filling gitti/boulder/packing at base & tightening stay to bring the pole vertical. Packing material by contractor.

Cutting/trimming of tree branches fouling 11 kV/33 kV lines and clearing the line for safe supply, with safe disposal of cut material.

Earthing of poles by Gl earth rod/pipe with earth-wire connection; earth resistance as per IE Rules/CEA Regulations. Earth rod by contractor.

Providing and fixing of cradle/cage guarding of LT/HT lines at road/route crossings over the Kanwar route to maintain safe ground clearance per CEA Safety Regulations / IS 5613. The guarding shall comprise two bearer/guard wires cross-laced into a cradle below the conductors and earthed at both ends, complete with guarding cross-arms (at supporting poles, average span -15m) and cross-lacing/binding at intervals not exceeding 1 m. Measurement is per running metre of the guarded span, and the rate is deemed to include the complete cradle- both bearer wires + all cross-lacing + cross-arms + supports earthing-for that length; it is NOT the length of a single wire/cable. Gl guard wire (6 SWG) issued by the Department; cross-arms, lacing wire (10/12 SWG), binding wire (14/16 SWG), fittings, earthing and all labour by the contractor.

Providing and Insulating HT/LT poles against probable leakage current by wrapping insulating plastic sheet of thickness >=50 micron (UV-resistant, weatherproof) from ground up to 8 ft (2.4 m) height in NOT LESS THAN 2 complete layers with minimum 50% overlap, bound sufficiently TIGHT at top, middle & bottom (no slack/slippage) so that no pole surface is exposed within 8 ft

Providing and fixing of rigid uPVC casing pipe of 225 mm nominal outer diameter (9 inch), minimum wall -4 mm, UV-stabilised (non-pressure casing grade), as slip-casing over round ST/STP poles from ground level up to 8 ft (approx. 2.5 m per pole); the bore (~217 mm) fits all pole classes-9m (-140 mm), 11 m (-165 mm) and 13 m (~194 mm base, per IS 2713). The pipe shall be slipped over the pole (or longitudinally slit and closed around it) and secured with a minimum of 3 nos MS clamps (top, middle and bottom), the clamps being welded to hold the casing firmly in position. Applicable to round poles. All material to be supplied by the contractor.
