Answer Posted / c.satheeshkumar
1.For earthed and un earthed XLPE cables, the IS 7098 part2
1985 does not give any difference in specification. The
insulation level for cable for unearthed system has to be
more. In simple statement the manufacturers states that 11
KV earthed cable is suitable for use in 6.6 KV unearthed
system.The process of manufacture of cable is same. The
size of cable will depend on current rating and voltage
level.
what IS specifies and I quote below:
" b) Voltage Grade (Uo/U)
1) Earthed System - 1.9/3.3 kV, 3.8/6.6 kV, 6.35/11 kV,
12.7/22 kV and 19/33 kV.
2) Unearthed System - 3.3/3.3 kV and 11/11 kV.
Note 1 - Cables of 6.35/11 kV grade (earthed system) are
suitable for use on 6.6/6.6 kV (unearthed system) also.

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
