Answer / amrita

LT Cables are designed for 490V & below voltages.
It has insulation of 1.1KV
HT cable are designed for 490V & more i.e; 6.6KV,11KV etc.
It has insulation of 11KV & above.

Answer / er.arun babu s

HT cable has contain phases only not neutral core 1 or 3 core 1ly insulation was thick but 
 
LT cable has contain additional neutral have core 3.5 and 4 

Answer / c.annarajan

Difference between LT and HT
1. Use Below 450V Above 500
2. Insulation XLPE , XLPE and Double Layer insulated
3. Core(Neutral) Yes No
4. Grading 1100 V Above 110KV
5. O.D. - Lesser than LT
6. Current
Carring Cap. - Less than LT
7. Voltage
Carring Cap. - Greater than LT

Answer / k. parasiramreddy

HT Cable is heavy duty cable and high volts , ht is no neutral,

LT Cable is pvc cable, and most load ,
Medium volt's and full load

Answer / zahed

do earthing conductor comes from transformer side to main
distribution board?
what is the difference between TN-S,TN-C,TN-C-S?

Answer / sunil

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

Answer / raja

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 / sunil kumar

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