Ps Explain YWY,AFWY Type Cable
Answer / sanket
YWY- IT MEAN COPPER CONDUCTOR,Y- PVC SHEATH,W-SINGLE ROUND
WIRE ARMOUR Y- PVC INSULATED CABLE..
AFWY DONT KNOW BUT U CAN FIND LIKE THIS
IF THERE IS NO MENTION FIRST IT MEAN COPPER CONDUCTOR(1)
A- ALLUMINIUM COND.(1 CHARACTER)COPPER OR ALU.CONDUCTOR
Y- PVC SHEATH (2)
F- SINGLE ROUND WIRE ARMOUR (3)EITHER F,W OR FF,WW
W- SINGLE STRIP ARMOUR (3)
FF-DOUBLE ROUND WIRE ARMOUR (3)
WW-DOUBLE STRIP ARMOUR (3)
Y - PVC INSULATED(4)

Application of DC motors is generally restricted to a few load speed applications because of _____.
Three set (each phase contain 2 cable of 400 mmsq CU XLPE AWA) of single core cables are connected to 11 KV motor of 14 MW & the switch gear supplay is taken from 11kv feeder & this supplay taken from 275 KV substation. Problem is one pair cable(L3- 2 cable ) getting very hot & gland melted and damaged in switch gear side. the other two cable haven't any more hot(ambient temp only & L3 haveing 95- 100 Degree C. The same problem happened in 275 KV substation switch gear side also where the supply taken for 11 kv switch gear. But here L2 phese cable had problem. Why it is happening like this?. The cable having temperature different at different location from gland side inthe case of 11KV feeder of 275 kv substation. why ?
