classification of underground cable is done on varies basis.
1) ON THE BASIS OF NUMBER OF
CORE
2) ON THE BASIS OF VOLTAGE
3) ON THE BASIS OF
APPLICATION
4) ON THE BASIS OF
INSULATION
5) ON THE BASIS OF SHEATH
6) ON THE BASIS OF ARMOURING
7) ON THE BASIS OF
CONSTRUCTION
Base on Above
Classification, we will summerise.
1) ON THE BASIS OF NUMBER OF
CORE
1 - core
2 - core
3 - core
3.5 - core
4 - core
2) ON THE BASIS OF VOLTAGE
A. Low Tension (LT) cable _
operating voltage up to 1KV
B. High Tension (HT) cable _
operating voltage up to 11KV
C. Super Tension (ST) cable
_ operating voltage up to 33KV
D. Extra High Tension (EHT)
_ operating voltage up to 66KV
E. Extra Super Tension (EST)
_ operating voltage up to 132KV
3) ON THE BASIS OF
APPLICATION
A. Power Cable _ Use for
transmission & Distribution of Power.
B. Control Cable _ Used for
transmission of Control Signals.
4) ON THE BASIS OF
INSULATION
A. Rubber Insulated
B. PVC Insulated

D. aluminium sheathed
6) ON THE BASIS OF ARMOURING
A. Single Layer Steel Wire
Armoured
B. Double Layer Steel wire
Armoured
C. Double Layer Steel tape
Armoured
7) ON THE BASIS OF
CONSTRUCTION

F. Super tension cable
·
Oil-filled cable
·
gas pressure cable
USES OF DIFFERENT TYPES OF
CABLE:-
1. LT (Low Tension) Cable _
in distribution, street light, machine wiring in factories.
2. Beltd cable _ in LT &
HT Distribution.
3. H type cable _
Manufacture for 66KV rating (LT transmission line)
4. OIL filled / Gas-filled
Cables _ Manufacture for 132KV, 220KV (for primary transmission line)
