Product DescriptionOufdoorimmersed bushingBushing, one end of which
is intended to be in ambient air and exposed to outdoor atmospheric
conditions and the other end to be immersed in an insulating medium
other than ambient air (e.g. oil or gas).Creepage distanceShortest
distance along the surface of an insulafor between fwo conducfive
partsMinimum nominal creepage distanceUnless otherwise agreed
between purchaser and supplier, or demonstrafed by a fest, the
creepage distance in accordance with lEC 815 isdetermined by Ur/KVl
x dcs /mm/kV)x kD where;Arcing distanceShortest distance in citr
extemal to the insulator between metalic parts which normally have
the operating voltage between them.AltitudeAlthough the insulafion
level refers to sea level, bushings coresponding fo this standard
are declared suitable for operafion at any altitude not exceeding
1000 m. in order to ensure hat the external withstand voltages of
the bushing are suficient at alitudes exceeding 1000 m, the
arcing distance normally required shall be increased by
a suitable amount. It is not necessarv to adjust the radial
thickness of insulation or the clearance of the immersed end. The
puncture strength and the flashover voltage in the immersion medium
of a bushing are not affected by altitude.To the limitations of
puncture strength and flashover voltage in the immersion medium it
may not always be possible to check the adequacy of the increased
arcing distance by actual test at any altitude lower than that of
operation. In such a case the supplier shall demonstrate by the
amount of increase of the arcing distance, that the bushing is
adequate.For general guidance an increase of 1,0% of the arcing
distance necessary at sea level for each 100 m in excess of 1000 m
up to a maximum of 3000 m above sea level should be applied.EXAMPLE
Altitude of installation 2800 m;Increase in arcing
distance.Material: porcelain in accordance group C100 or equivalent
maferial. Colour: brown (other materials are allow by previous
agreement) Surface: glazed excepting for the worked surfaces.
