Uhlolojikelele

(Intambo yesihlahla nentambo yesikhala) 25kV ikhebula lasemoyeni elihlanganisiwe i-AAC Intambo yesihlahla noma ikhebula yesikhala ekhiqiziwe, yahlolwa, futhi yaqokwa ngokuhambisana ne-ICEA S-121-733, okujwayelekile kwe-Tree Wire kanye ne-Messenger Supported Spacer Cable, inezintathu Izendlalelo ze-PE ezingazweli kumathrekhi.
Ungqimba lokuqala lwalesi sakhiwo esinezingqimba ezintathu yisihlangu somqhubi, esilandelwa yizingqimba #2 kanye no-#3 zesembozo.

Isicelo

Ukuze ugweme amaphutha okuxhumana noma ezimeni lapho sishoda khona indawo, ikhebula lasemoyeni (intambo yesihlahla nentambo yesikhala) ivamise ukusetshenziswa ezinhlelweni zokusabalalisa ezihamba phezulu nesesibili zikalwe ngo-25 kV (okuvamile).
Uma kwenzeka ukuthintana nezihlahla noma ezinye izilwane zasendle, ukwakheka kwethrekhi okunezingqimba ezi-3 kuqeda imijikelezo emifushane nama-flashavers.Lolu hlelo lungamisa ngempumelelo ukwehluleka kwesistimu, ukulimala, noma imililo ebangelwa ukuwa kwezihlahla noma amagatsha lapho lubekwe kahle.

Ukwakha

Umqhubi:
Umqhubi we-AAC.

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

Isembozo sangaphakathi nangaphandle:
Isembozo se-polyethylene enesendlalelo esi-2 esiphansi, esimaphakathi noma esiphezulu (LDPE, MDPE noma i-HDPE), lapho ungqimba lwangaphandle lumelana namathrekhi (TK-MDPE noma i-TK-HDPE).Zonke izendlalelo zihlanganiswe ndawonye.Ungqimba lwangaphandle luzoba mnyama noma lube mpunga, lumelane nokukhanya kwelanga futhi lukwazi ukumelana namathrekhi.

Ikhebula le-ASTM 25kV I-Aerial Tree Wire AAC I-PE enezingqimba ezi-3 engazweli kwithrekhi (2)
