Voltage level is different in LT & HT cables.
LT is low tension i.e Low voltage & H.T is high tension i.e High voltage .
Generally 433 v (or 1.1 kV in cable ) is LT system and
3.3 KV, 6.6 kV , 11 KV, 22 KV , 33 KV etc are HT cables.

Question is not about difference of HT & LT. When question come in cable, the main difference is in Insulation level. Because of high voltage there should be more insulation in HT cable.

As the voltage ratings have been defined in previous answers but dere are more consideations that have to be made, such as height of pole carrying transmission line wires which will be more in case of HT lines, cause there may be static discharge to ground and may cause arking and heavy transitions, the insulations have to be made strong, circuitbreakers have to be higher capacity such as SF6 circuitbreakers. the basic of LT is used for secondary distribution has low voltage so low protections, where is HT lines are for Primary consumers such as industries.

L.T: Without shield cable.
H.T: With / Without shield cable.

Inn HT cable dielectric insulation is there or else because of high voltage outer most electron of air atom will get detached from the atom and will provide a conducting path from phase to phase or earth. This may cause a flash over

L.T. means low tension use for below 1000 volts normally pvc cables
H.T. means high tension cable use for more then 1000 volts normally are xlpe shielded cables
