PORTABLE EARTHING DEVICES WITH
STICKS PZ110-220SH, PZ330-500SH
|
 |
|
These
devices are designed for applying on
to 110 to 500 kV overhead lines wires of commercial frequency for
separate earthing of wires with 90 to 600 mm2
cross-section area of disconnected overhead lines in order to protect
personnel in case of accidental
energization
of the section or appearance of induced voltage in the section.
Permissible operating
temperature is from –25oC to +55oC at air
relative humidity up
to 80% at 25 oC.
