SU4420 : Pylons are bigger than you think (4)
taken 16 years ago, near to Chandler's Ford, Hampshire, England
Pylons are bigger than you think (4)
After replacing the righthand insulator string, the whole process is repeated for the lefthand one. Here the old insulator is being lowered to the ground. A hydraulically operated capstan winch on a Landrover below is used for the lifting tasks.
The metal hoop within which the lower man is standing is a precaution against the wires being struck by lightning. In that event an arc will pass from the hoop through the air onto the metal of the pylon, rather than arcing over the surface of the insulators and damaging them.
