Isicelo

Ikhebula le-ASTM 25kV Space Aerial lisetshenziswa ezindaweni ezinekhava yezihlahla eziphakeme, izindawo ezinezindawo ezivulekile eziqinile, imigwaqo kanye nezindawo ezivulekile ezinde.Le divayisi isondeza izintambo zamandla ngaphandle kokuzivumela ukuthi zithinte.Ngaleyo ndlela, avikelekile emagatsheni awile, emoyeni, noma kwezinye iziphazamiso.

Ezokwakha

Ikhebula elilodwa elinesihlangu esi-3-ungqimba olunwetshiwe kanye nesistimu yokumboza eyenziwe yisivikelo somqhubi we-semiconducting thermoset ekhishiwe kanye nesembozo sezendlalelo ezi-2, esiqiniswe ngensimbi ye-aluminium conductor.
I-XLPE yenza ungqimba lwangaphakathi lwesembozo, futhi i-TR-XLPE yenza ungqimba lwangaphandle.
Isendlalelo ngasinye sihlanganiswe nesibopho.

Umqhubi:
I-AAC (1350-H19, iminyene).

I-Conductor Shield:
Isihlangu esinwetshiwe se-semiconducting thermoplastic esikhumula mahhala ku-conductor futhi sihlanganiswe nesembozo.

Isembozo sangaphakathi nangaphandle:
Isembozo se-polyethylene engu-2-layer crosslinked (XLPE), lapho ungqimba lwangaphandle lumelana namathrekhi (TK-XLPE).Zonke izendlalelo zihlanganiswe ndawonye.Ungqimba lwangaphandle luzoba mnyama noma lube mpunga, lumelane nokukhanya kwelanga futhi lukwazi ukumelana namathrekhi.
