RTE’s breadth of work covers the
largest electricity network in Europe,
with 100,000km of lines in France, some
of which carry currents up to 400kV.
In addition to its five H135s that were
purchased specifically for power line
surveillance and maintenance work, RTE
currently operates an H215 and two H225s
for heavy-duty work, such as moving pylons.
Five H125s are used for inspection duties
in mountainous areas, and an AS355N
conducts human external cargo missions
with heli-baskets. The live-line system
is designed to address the 500kV
requirement of networks in countries
such as China and the US.
Addressing the evolution of the power
line market and its maturity, the Airbus
spokesperson explained that aspects like
inspection, maintenance and repair are
primary areas that continue to be most
important, with operators having to make
sure their work does not cut electricity
or stop service to local populations.
‘Countries in Asia, Latin America and
Africa have recently started building their
networks from scratch and are focused on
quick and sustained construction growth.
So, different parts of world have different
development issues requiring different
solutions,’ the spokesperson noted.
Alhough the OEM did not disclose exact
numbers of its power line operator base, it

Role dependence
According to both Kraus and Reno, the
Airbus H135 and H145 are the most
popular rotorcraft used by operators for the
dedicated EMS role. Kraus said that these
two platforms take a market share of ‘60%
or more’.
The main benefits of these helicopters
are that they are dual-engine models and
have more power and therefore can take
more weight. Reno noted that in terms of
single-engine aircraft, the Bell 206 and 407
are popular options alongside A-Star and
Twin Star helicopters in the US, and the
AW109 and AW119 series are also
becoming more popular.
‘For the H135 and H145, you are really

Reno insisted. ‘The 145 has quite a large
