Isicelo

I-15kV Aerial Power Cable (intambo yesihlahla nentambo yesikhala) I-AAC (icwecwe) i-PE enezingqimba ezi-3 engavimbeli ithrekhi ihloselwe ukusetshenziswa kumasistimu okusabalalisa aphezulu aphezulu kanye nakwesibili alinganiselwe ngo-15 kV (okuyigama) ngokuvamile ukuvimbela amaphutha ngenxa yokuxhumana noma lapho isikhala sikhona. okulinganiselwe.Isistimu enezingqimba ezi-3 ezimelana nethrekhi ivimbela ama-short-circuits kanye nama-flashavers esimweni sokuxhumana nezihlahla noma izilwane zasendle.Uma ifakwe ngendlela efanele, lesi simiso sisebenza ngempumelelo ekuvimbeleni ukucisha kwesistimu, ukulimala, noma imililo ngenxa yokuwa kwezihlahla noma amagatsha.

Intambo Yesihlahla

Uma isetshenziswa kusistimu yamandla ezintambo zesihlahla, ifakwa ekucushweni okuyisicaba, ngendlela efanayo kanye nesikhala kuma-insulators njengamakhondaktha angaphezulu angenalutho noma amboziwe.Ama-conductor azisekelayo, afana ne-ACSR, ajwayelekile kulolu hlobo lokufakwa.

Ikhebula le-Spacer

Uma isetshenziswa kusistimu yamandla ekhebula yesikhala, ifakwa ngesikhala esifanayo ekucushweni kwedayimane okugcinwa yi-spacer hardware.Ukuhlanganiswa kwe-spacer nekhebula kusekelwa yisithunywa esingenalutho, njengensimbi engenalutho ye-aluminium, i-ACSR, i-OPGW, noma izintambo zensimbi.Amakhebula e-Spacer athatha indawo encane, edinga indlela encane yendlela noma iphaseji.

Ezokwakha

Ikhebula elilodwa elinekhondatha ye-AAC, isihlangu esinwetshiwe esinezendlalelo ezi-3 kanye nesistimu yokumboza, ehlanganisa isivikelo somqhubi we-thermoplastic esikhishiwe, kanye nesembozo sezendlalelo ezi-2.Isendlalelo esingaphakathi siyi-polyethylene ephansi, emaphakathi noma ephezulu (LDPE, MDPE noma i-HDPE), kuyilapho ungqimba lwangaphandle lumelana namathrekhi i-polyethylene ephakathi nendawo noma ephezulu (TK-MDPE noma i-TK-HDPE).Zonke izendlalelo zihlanganiswe ndawonye.

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

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

-Isimbozo 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.
