Technical
Improvement
As transmission system operators
have sought further solutions to assist them with
their transmission projects, both cable and overhead
line manufacturers have developed new solutions
designed to improve the flexibility of their products
and to reduce costs.
For overhead lines, the principal
issue has been to improve the strength of towers
whilst reducing the visual impact. For underground
cables, the drive has been to reduce costs and
to ensure that reliability expectations are met.
Advances in materials have ensured
that the low cost potential of XLPE insulation
materials in underground cable systems has been
available in a reliable form for many years. Consequently,
the key issues that transmission system operators
have to consider are associated with maintenance
and the detection of faults.
Choose from the topics below to
learn more about how cables contribute to lower
overall system maintenance and how new cable technology
allows faults to be rapidly and precisely located
and repaired.
