| Abstract |
Prescribes specified values for the electrical and mechanical
characteristics and for the principal dimensions of string insulator
units of the long rod type with insulating parts of ceramic material
intended for a.c. overhead lines with a nominal voltage greater than
1 000 V and a frequency not greater than 100 Hz.
It is also applicable to insulators of similar design, used in
substations.
Applies also to string insulator units:
-of the long rod type either with a clevis at both ends for coupling
with a tongue, or with a socket at both ends for coupling with a pin
ball
-with external metal fittings
-for use on overhead lines situated in slightly polluted areas, and
the creepage distances given in Tables I and II have been
established accordingly
-and insulators of similar design, used in substations.
This standard may be regarded as a provisional standard for
insulators for d.c. overhead lines.
Note -For general definitions and methods of tests see IEC 60383.
-For dimensions of clevis and tongue couplings of string
insulator units, see IEC 60471.
-For dimensions of ball and socket couplings of string
insulator units, see IEC 60120.
