Question
what is the difference between the HT Cable and LT Cable ?
 Question Submitted By :: Guest
I also faced this Question!!     Rank Answer Posted By  
 
  Re: what is the difference between the HT Cable and LT Cable ?
Answer
# 1
HT MEANS MORE THAN 500V
LT MEANS LESS THAN 450V
Michael Faraday (1791-1867) an Englishman, made one of the
most significant discoveries in the history of electricity:
Electromagnetic induction. His pioneering work dealt with
how electric currents work. Many inventions would come from
his experiments, but they would come fifty to one hundred
years later.

Answer
# 2
Basic difference is the dielectric strength/ thickness of
insulation. For LV PVC is OK. However, for HT cable cross
linked poly ethylene(XLPE) is used.

Answer
# 3
In HT cable used single core but in LT used multicore.
Insulation desine with carrying voltage. HT cable unarmoud
but LT is armoud.

HT cable have only 3 core.having semiconductor layer on
core insulation.
LT have 3.5/4 core.

Answer
# 6
In High Tension cable there is no Neutral.In market will
get only 1,3 core cbles where as in LT cable there is a
neutral U have to prefer for 3.5 or 4 core cable.HT cable
having Screen to avoid voids and cavities.

  Re: what is the difference between the HT Cable and LT Cable ?
Answer
# 8
the basic diff is of grading of the cable.
for HT- 6.35/11 Kv
for LT-1100 Voit

  Re: what is the difference between the HT Cable and LT Cable ?
Answer
# 9
The basic differance betwwen the HT and LT cable is
insulation of the cable. Because of insulation is always
govern by voltage level so we have higher on HT cable
compare to LT cable

  Re: what is the difference between the HT Cable and LT Cable ?
Answer
# 10
LT HT
1. Use Below 450V Above 500
2. Insulation PVC XLPE
3. Core(Neutral) Yes No
4. Grading 1100 V Above 11KV
5. O.D. - Lesser than LT
6. Current
Carring Cap. - Greater than LT
