EE0770 : HV/MV/LV Cable Specifications, Installation, Commissioning, Splicing, Jointing & Termination

This practical and highly-interactive course includes
practical sessions and exercises where participants
carryout HV/MV/LV cable specifications, installation,
commissioning, splicing, jointing & termination.
Theory learnt in the class will be applied using the
latest heat-shrink jointing and termination methods
suitable for in-class training.
The range of voltage and capacity of power transmitted
through cables is showing a steady increase over the
years. Environmental concerns, aesthetic issues, lack of
transmission corridors and difficulty in routing overhead
lines in crowded human habitats are some of the reasons
for the explosive growth of cable technology well into the
new voltage range. Due to physical limits on cable
lengths for manufacturing and packaging, joints in cable
become inevitable, particularly in the context of the utility
sector. The cables need to be also terminated at sending
and receiving end equipment, a very wide variety of
them, in utility as well as industry applications and these
calls for appropriate cable termination accessories.
Cable terminations and joints form the weakest link in
any distribution system. Also, a failed joint in an
underground distribution system is much more difficult to
locate and repair compared to any similar problem in
overhead distribution systems. This means that we
should do our utmost to achieve a good joint or
termination, which can give years of trouble-free service.
The quality of a joint or termination depends to a large extent on the skill of cable
jointer/splicer. The aim of a cable jointer/splicer must therefore be to obtain a joint which
electrical properties are as good as the original cable both in electrical and mechanical
terms. The design of cable splicing, jointing and termination accessories is based on this
perception. Dependence on operator-skill is sought to be reduced to the extent possible
by good choice and quality of jointing materials, though such dependence cannot be
totally eliminated.
This course is designed to provide participants with a detailed and an up-to-date
overview of HV/MV/LV cable specifications, installation, commissioning, splicing, jointing
and termination. It covers the cable jointing and the different types of cables, insulation
materials, terminations and joints; the construction of cables, conductor materials and
configurations; the different applications and voltages of cables; the various types of
cable connectors, materials and method of connection; the theory of joints and
terminations; the stress control and the effect of joints and terminations on stress
gradients; the areas requiring stress control; the cable jointing, splicing, testing and
termination; the applicable standards, types of tests, routine tests and its limitations; the
training and certification of personnel involved; the reasons for cable failures and
analysis of failures with a predictive approach; and the new trends and technologies
utilized in the industry.
