Difference Between HT and LT Cables

Difference Between HT and LT Cables

Cables are the most critical part of the entire power
transmission systems as cables are the physical
mediums used to transmit power from point A to
point B. All aspects of the industry & even our
homes use some or the other type of cable which is
accountable for the safe transfer of power to our
locality, bringing that power in our homes, as well
as to run our electrical gadgets.
Cables can be classified as Low tension or low
voltage cables & High tension or high voltage cables
on a very broad level for better understanding.
Many cable makers are involved in the
manufacturing of both Low tension and High
tension cables and most of them sport identical
capabilities and specifications. The categorization
basically boils down to the specifications. Cables
which have 3.3kV to 33kV rating can be categorized
as high tension cables & cables sporting a rating of
1.1kV can be sorted as low tension cables. Some
cables with specialized applications come under the
EHV or extra high voltage cables category.

Construction of these cables is identical to
every other cable. Basic parts of these cables
are the conductors, inner and outer sheaths,
insulating layers, filler material, armor and
copper taping. A few cables which fall under
the class of power transmission cables, but
transmit the power via over head mediums
are also LT cables popularly known as aerial
bunched cables. These cables are safe,
reliable, have very less power losses, less cost
of operation and maintenance. Such cables
are perfect option for installations in semi
urban, rural, forest area or regions with
difficult terrain. Such aerial bunched cables
are manufactured and tested according to
IS:14255 & other specifications. These cables
have amazing protection against line and
ground faults.

Typically HT cables have a simple and tough
construction. At the core a copper or
aluminium conductor can be found. Over the
top of this conductor, inner semicon is placed
which is then wrapped with XLPE insulating
material. Outer semicon wraps the XLPE
insulation. Finally the conductor is wrapped
by a copper metal tape. All the other
conductor cores are wrapped in the similar
way.
