Thumela i-imeyiliIzintambo zikagesi ze-XLPE ezifakwe ugesi eziphakathi nendawo ezingama-19-33kV zifanelekela amanethiwekhi okusabalalisa noma okwesibili okudlulisa, ngokuvamile zisebenza njengomthombo wamandla oyinhloko wamanethiwekhi ezentengiselwano, ezimbonini, kanye nawasemadolobheni. Zifanelekela izinhlelo zamanje ezinephutha elikhulu ezinama-current anephutha alinganiselwe afinyelela ku-10kA/1 umzuzwana. Izakhiwo ezinomthamo wamanje onephutha eliphakeme zinganikezwa uma ziceliwe.
Ukwakhiwa:
Izinto zomqhubi:Izinketho zifaka phakathi ithusi eligoqekile, eliqinile nelihlanganisiwe noma i-aluminium.
Isivikelo somqhubi:Inhlanganisela ehambisa ugesi kancane esetshenziswa yi-extrusion phezu komqhubi.
Ukuvikela:Inhlanganisela ye-polyethylene exhumene (XLPE) ehambisana ne-AS/NZS 3808. I-XLPE inikeza ukumelana nokushisa okuphezulu kanye nokumelana nokuhuzuka uma kuqhathaniswa ne-PVC.
Ukuvikela ukuvikela:Inhlanganisela ye-semiconductive ekhishwe emboza ungqimba lokufaka umswakama.
Izinga lokushisa eliphezulu lokusebenza:Ama-conductor angasebenza ekushiseni okuphezulu okuqhubekayo okungu-90°C.
Izinga lokushisa eliphakeme kakhulu le-short-circuit:Ikhebula lingamelana nokushisa okuphezulu kwe-short-circuit okungu-250°C kuze kube yimizuzwana emi-5.
Ukuvikela insimbi:Ngokuvamile kwenziwa ngocingo lwethusi oluhlanganisiwe noma i-tepi yethusi.
Izivikelo zensimbi:Izinhlobo ezihlonyisiwe zifaka intambo yensimbi egayiwe (i-SWA) yezintambo ezinama-core amaningi kanye nentambo ye-aluminium (i-AWA) yezintambo ezinama-core owodwa.
Izinto Zokumboza:
Igobolondo elijwayelekile liyinhlanganisela emnyama ye-PVC engu-5V-90.
Ezinye izindlela ze-LSZH (Low Smoke Zero Halogen) zifanelekela izindawo zangaphakathi, zomphakathi, noma ezinye izindawo ezidinga ukubhekwa kokuphepha komlilo.
Ijazi le-polyamide (inayiloni) elikhishwe ngaphandle lingangezwa ukuze kuvinjwe umuhlwa.
I-HDPE (High-Density Polyethylene) yangaphandle ingasetshenziswa futhi njengenye indlela.
