Thumela i-imeyileIintambo zamandla ze-XLPE ezifakwe i-insulation ye-19-33kV zifanelekile kwiinethiwekhi zokusasaza okanye zothumelo lwesibini, zihlala zisebenza njengombane ophambili kwiinethiwekhi zorhwebo, zemizi-mveliso, nezedolophu. Zifanelekile kwiinkqubo zamandla aphantsi aphezulu anee-currents ezilinganiselweyo ukuya kuthi ga kwi-10kA/1 second. Izakhiwo ezinomthamo wamandla aphantsi aphezulu zinokubonelelwa xa ziceliwe.
Ulwakhiwo:
Izinto zomqhubi:Ezinye izinto ezikhethwayo ziquka ubhedu oluqhekekileyo, oluqinileyo noluxineneyo okanye i-aluminium.
Ukukhusela umqhubi:Ikhompawundi eqhuba kancinci esetyenziswa yi-extrusion phezu komqhubi.
Ubushushu:I-polyethylene edityanisiweyo (XLPE) compound ehambelana ne-AS/NZS 3808. I-XLPE inika ukumelana nobushushu kunye nokungagugi kakuhle xa kuthelekiswa ne-PVC.
Ukukhusela ubushushu:Ikhompawundi ye-semiconductive ekhutshiweyo egubungela umaleko we-insulation.
Ubushushu obuphezulu bokusebenza:Ii-conductors zingasebenza kubushushu obuphezulu obuqhubekayo obuyi-90°C.
Ubushushu obuphezulu be-short-circuit:Intambo inokumelana nobushushu obuphezulu be-short-circuit obuyi-250°C ukuya kuthi ga kwimizuzwana emi-5.
Ukukhusela isinyithi:Ngokwesiqhelo yenziwe ngocingo lobhedu oluxutyiweyo okanye iteyiphu yobhedu.
Izixhobo zesinyithi:Iinguqulelo ezixhotyisiweyo ziquka ucingo lwentsimbi olune-galvanised (SWA) lweentambo ezine-core ezininzi kunye nocingo lwe-aluminium (AWA) lweentambo ezine-core enye.
Izinto zoMngxunya:
Isiciko esiqhelekileyo simnyama sePVC compound 5V-90.
Ezinye iindlela ze-LSZH (Low Smoke Zero Halogen) zifanelekile kwiindawo zangaphakathi, zikawonke-wonke, okanye kwezinye iindawo ezifuna uqwalaselo lokhuseleko lomlilo.
Ijakethi ye-polyamide (nylon) ekhutshiweyo ingongezwa ukuze ikhusele iintubi.
I-HDPE (High-Density Polyethylene) yangaphandle ingasetyenziswa njengenye indlela.
