Due to damage that may have occurred during transport, a visual
inspection of the insulators' condition is required before every in-
itial filling and commissioning, as well as after maintenance work
or any other actions.
Therefore:
- all present persons must take cover or
- comply with the following minimum distance:
for porcelain insulators: approx. 50 m
for composite insulators: the height of the device
(measured from ground level to the upper edge device)
The filling gas must be used purs. to IEC 60376.
