that runs between a transformer and a house) Relatively safe ... but power
lines come in a whole variety of voltages and cable types. Some insulated
The very dangerous high-voltage transmission lines (which transmit power
over long distances from the power stations) are uninsulated (mostly because
a few millimeters of plastic woudn't be any use at all against hundreds
of thousands of volts. That kind of voltage could drive deadly current
through your kite lines (even if dry) and your body, if you flew a kite
into them. They are always on high pylons but some transmission lines are
well within reach of kitelines.
Medium voltage distribution lines (thousands or tens of thousands of
volts - the kind that run between substations or from substations to
transformers) may be insulated but are most often not insulated.
That voltage may not be capable of killing you through dry kitelines but
could easily do so through wet or damp lines and would have no problem
frying you if you if you got dragged up onto them. Just pulling those
conductors together (or close) by wrapping a kiteline around them will
cause violent arcing, destroy your gear and probably cause fires.
It a good idea to keep kites as far as possible from power lines,
especially if you are not sure of the differences between
transmission lines, distribution lines and domestic overhead cables.
