Provat mbi izoluesit e postave në ambjentet e nrëndshme dhe të jashtëme me material qeramike ose qelqi për sistemet me tensione nominale më të mëdha se 1kV

Tests on indoor and outdoor post insulators of ceramic material or glass for systems with nominal voltages greater than 1 kV

Asnjë informacion i shtuar.

Applies to post insulators and post insulator units of ceramic material or glass for indoor and outdoor service in electrical installations or equipment operating on alternating current with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. Notes: -May also be regarded as a provisional standard for insulators for use on d.c. systems, see IEC 60438. -When considering hollow insulators, see HD 329. -Tests on indoor post insulators of organic material will be covered by a future publication: Tests on indoor post insulators of organic material for systems with nominal voltages greater than 1 000 V up to but not including 300 kV. -For artificial pollution and radio-interference tests, see EN 60437 and 60507. -For numerical values for insulator characteristics and for selection of insulators for specific operating conditions, see EN 60273.
