Unit rate (Rs): 2,500/-

Amount (Rs): 1,00,000/-


Item 4: End terminations of 11KV, 3 core, 95/70 Sq.mm XLPE / PVC cable along with the jointing materials such as heavy duty crimping type lugs, cable compound/putty, Empire/HT tapes etc., complete with the cost of jointing materials, labour tools & implements & as per the directions of engineer-in-charge.

Unit: Each

Quantity: 4 set.

Unit rate (Rs): 15,000/-

Amount (Rs): 60,000/-


Item 5: Buy-back offer for the existing 11KV, 400 Amps, 250 MVA capacity "Reyrolle burn" make oil circuit breaker together with P.T., on where is as is basis. The contractor has to lift the OCB at his own cost and risk and the amount thus quoted for taking back the OCB will be deducted/adjusted against the bill for other items.

Unit: Lump Sum

Quantity: 1 No.

Unit rate (Rs): 10,000/-

Amount (Rs): 10,000/-



Total = Net ( 1 + 2 + 3 + 4 - 5)=Rs. 6,07,000/-


Note: The above shown rates may be varied as per the location. This is for providing general information only.
