Incazelo emfushane:

Imibandela Yesevisi Ejwayelekile
Ukuphakama 1000- 3000m;
Izinga lokushisa lemvelo alikho ngaphezu kuka +40″C, hhayi ngaphansi kuka -30C (indawo ephakeme nebandayo ayikho ngaphansi kuka-40C);
Umoya ucindezela hhayi ngaphezu kuka-700Pa;(isivinini somoya esilingana no-34ms/s);
Amandla okuzamazama komhlaba aweqi ku-8 degree;
Ubukhulu beqhwa abukho ngaphezu kuka-10 mm;
Ukufaka indawo akufanele kube nokuqhuma kalula kwezimpahla eziyingozi, ukubola kwamakhemikhali nokudlidliza okunodlame;
Isihlukanisi sensika ibanga elingcolile endodaneni: Uhlobo olujwayelekile ikilasi elingu-0, vikela uhlobo olungcolile njengesigaba II.
Lolu chungechunge lokushintshwa kwe-Isolating luhambisana ne《GB 1985-89 exchanges high pressure insulating switch》
I-IEC129(1984> (ukushintshana kuvimbezela iswishi ngokuxhuma umjikelezo weswishi) ne-IEC694 (1980)《imishini yokushintsha ingcindezi ephezulu elawula okokusebenza ukuze ilawule into》izicelo ezihlukahlukene ngokuphelele.
