For LT cable
1. Use : Up to 690V
2. Insulation : PVC
3. Core(Neutral) : Yes
4. Insulation Grading : 1100 V
For HT cable
1. Use : Above 690
2. Insulation : XLPE
3. Core(Neutral) : No
4. Insulation Grading : Above 3.3kV, 11KV..etc
( Please note that now 690 V using in VFD application with LV cable and 440 V for DOT motor starter)

What precautions to be taken when working with Transformer?
Frist putt of the main incomer HT side then Rack out the breaker and put the LOTO after that Discharge the cable Both side (HT/LT).
Why Vacuum circuit breaker is using HT and why Air circuit breaker is using in LT?
Dielectric Strength of Vacuum is more than that of Air. In HT voltage is more than LT. So VCB is used in HT & ACB in LT. Rakesh Gaikwad
What is the benefit of using HT Motors instead of LT?
to reduce Current and Coast
What is the difference between HT and LT line?
ht cable that means voltage level is high , it is obvious that power is going to remain same ,so if voltage rises ,current has to be lowered .since current level is less in ht cable therefore size (dia) is less compared to l.t cable , (p=v.i),lt cable current rating is more and voltage rating is less
What are HT and LT drives?
HT drives are the pumps or motors operate at more power typically more than 0.5 Amps at 110 or 220 V DC whereas LT drives operate at lesser power less than 0.5 Amps at 24 V DC or 240 V AC.

What is the full form of LT and HT motor?
LT motor abbrevation
What are different Testing steps of HT and LT panel?
The different testing steps of HT and LT panel include commissioning, sanctioning, erection and the CPP set. All this is done in the servicing of the transformers and the HT/LT control panels.
What is difference between lt and ht pannel?
lt pannel is a iow tensan pannel. lt pannel work is 240v and 440v. ht pannel is a high tensan pannel . ht pannel work is 11kv,33 kv ,66kv, 120kv
What is an LT cable?
An LT cable is a low tension (or low voltage) cable.
What is the main difference between HT and LT Lines?
It's the voltage: HT high voltage LT low voltage Tension = voltage (French?)

How can you tell Volvo C70 LT or HT?
The 1999, 2000, 2001 C70 engines that are HT are the 2.4 L Engines. The LT engine is the 2.3 L but it produces more horsepower than the HT.
What is difeerence between ht motor and lt motor?
ht motor is to be fed with more than 415v like in kvolts. all the other operated below 415 volts are lt motors
What is difference between the HT panel and LT panel?
An LT panel is a device that receives power and distributes it to other devices and boards. An HT panel is the same thing except it is used for high tension cables.
What is the benefit of using HT Motors instead of LT?
to reduce Current and Coast
Why the HT and LT voltage in the multiple of 11?
because our system form factor is 1.1
