Izoluesit -Provat në suportet e izoluesve të brendshëm të materialit organik për sistemet me tensione nominale më të mëdha se 1 kV por duke mos përfshirë 300 kV

Insulators - Tests on indoor post insulators of organic material for systems with nominal voltages greater than 1 kV up to but not including 300 kV

Asnjë informacion i shtuar.

Applicable to post insulators of organic material for indoor service in electrical installations or equipment operating in air at atmospheric pressure on alternating current with a nominal voltage greater than 1 000 V up, but not including, 300 kV, as defined by range I of EN 60071-1, and a frequency not greater than 100 Hz. Composite insulators are not covered by this standard. The object of this standard is - to define the terms used, - define electrical and mechanical characteristics of post insulators of organic material and to prescribe the conditions under which the specified values of these characteristics are verified, - to prescribe methods of testing, - to prescribe acceptance criteria. This standard does not give numerical values for insulator characteristics, nor does it deal with a choice of insulators for specific operating conditions. HD 578 S1 specifies numerical values for electrical and mechanical characteristics and gives the dimensions necessary for interchangeability of post insulators.
