Ipulasitiki enezintambo zethusi izintambo zamandla kagesi ezigxilile ezibekwe ezimayini zamalahle Isithombe esifakiwe

Izintambo zikagesi ezinezimbombo zethusi ezinezinsimbi zethusi ezibekwe ezimayini zamalahle

Lolu hlobo lwekhebula lufanele ukusetshenziswa ekufakweni okungaguquki emigqeni yokudlulisela/yokusabalalisa ama-voltage akalwe angaphansi kuka-10KV njengendawo esuka egunjini lokusabalalisa eliphakathi nendawo ukuya egunjini le-electromechanical, i-transformer substation, indawo yokusebenzela yezimayini ephelele kanye ne-switchgear.Ikhebuli inesici sokubambezeleka kwelangabi eliphezulu.

Ngokuba izintambo zisetshenziswa ekumbiweni kwezimo eziyinkimbinkimbi kanye nemvelo engalungile, egcwele igesi kanye ne-smut, ukuvezwa okubangelwa kalula, izintambo zikagesi zepulasitiki ezivale amalangabi azinazo nje izakhiwo ezishiwo esahlukweni sokuqala sale ncwadi, kodwa futhi zine impahla ye-high flame retardant.Phakathi kwazo, leyo enendawo enkulu ephambanayo engu-50mm nangaphezulu kufanele idlule ekuhlolweni kokuvutha kohlobo A Lokuqoqa Intambo Kagesi nekhebula.Uma ingaphansi kuka-50mm², kufanele idlule ekuhlolweni kokuvutha kohlobo B oluqoqa izintambo zikagesi nekhebuli.

Izici

Izintambo zikagesi ezinezimbombo zethusi ezinezinsimbi zethusi ezibekwe ezimayini zamalahle

1. Izinga lokushisa eliphezulu lokusebenza

2. Ukuzinza kwesevisi okuqinile nokumelana nomlilo, ukuqinisekisa ngokuphumelelayo impilo yesevisi yekhebula.

3. Ubufakazi bokuqhuma

4. Ububanzi obuncane obungaphandle

5. Amandla aphezulu emishini

6. Umthamo omkhulu wamanje wokuthwala

7. Ukumelana nokugqwala okuphezulu

Lo mkhiqizo uyintambo yokubeka engaguquki negxilile enamandla kagesi alinganiselwe angu-1KV nangaphansi ezimayini zamalahle, futhi ifanele ukudluliswa kwamandla ezimayini zamalahle.Qinisekisa ukuphepha kwemishini kanye nokudluliswa kwamandla endaweni eyinkimbinkimbi

Lolu hlobo lwekhebula lufanele ukusetshenziswa ekufakweni okungaguquki emigqeni yokudlulisela/yokusabalalisa ku-voltacesess elinganiselwe kuno-10kV njengendawo esuka egunjini lokusabalalisa eliphakathi nendawo ukuya e-electromechanical chamber, i-movab-e transformer substation, indawo yokusebenzela yezimayini ephelele kanye ne-switchgear.Ikhebuli inesici se-oinigh flame retardancy.
