Isicelo

Izinkampani zensiza kudala zasebenzisa ikhebula le-spacer ukukhulisa ukwethembeka kwamanethiwekhi okusabalalisa okuyisisekelo kanye nekhwalithi yamandla ngenkathi ziqinisa ukumelana kwazo nokulimala kwesiphepho.
Idizayini yekhebula yesistimu yokusabalalisa izinsiza, ukuqina kwesistimu, nezakhiwo ezihlangene nakho kungasiza ekusingatheni ezinye izinkinga ezingaba khona.Ukuze kubhekwane nezindaba ezifanele futhi konge imali ngokwehlisa inani lezigxobo ezidingekayo, amasekhethi amaningi angabekwa esigxotsheni esisodwa ngenxa yokucushwa okuhlangene kanye nezidingo eziphansi zokuvunyelwa.
Izindleko zokunweba umthamo zingehliswa kakhulu ngokufaka ama-Over or Under Building Spacer Cable Systems kumasekhethi okuphakelayo, emigwaqweni, nasezikhungweni zesiteshi esincane.

Ezokwakha

Ikhondatha ye-AAAC kukhebuli eyodwa enesembozo sezendlalelo ezi-2, isihlangu esikhishwe izendlalelo ezi-3, nesihlangu esenziwe nge-semiconducting thermoset conductor esikhishiwe.
I-Crosslinked polyethylene insulation yenza ungqimba lwangaphakathi lwesembozo, kanye nesembozo sangaphandle se-polyethylene esinqamula ithrekhi sakha 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.
