Providing new copper windings in place of damaged winding including cost of material and labour, drying etc., Taking into account value of released copper which has to be retained by the repairer (Meeting IS 6160&7404 standards) New copper rate Rs 551.64/kg Sl.No.4 Scrap copper rate Rs 391.00/Kg Sl.No.19(a)
Net copper rate after deducting the scrap rate Rs.551.64-391.00=160.64 per Kg.
Untanking mass as per name plate =13705Kg
C&W Mass = untaking mass x 35% C&W Mass = 13705 x 0.35= 4797Kg. (4796.75)
Weight of solid insulation = C&W Mass x 20% = 4797*20%=959KG (959.4)
Hence Total wt of the copper = C&W mass - weight of solid insulation
= 4797 - 959= 3838
Total weight of the copper winding per phase =3838/3=1279 KG per phase (after GST)(1279.3)
