Isicelo

Amandla adla ngokusiwa kwintloko yenkonzo yomsebenzisi, xa uqhagamshelo kungeniso lwenkonzo lwenziwa, kusetyenziswa intambo yomoya ye-25kV engaphezulu.
Ukuba isetyenziswe kunye namaqondo okushisa angaphantsi kwe-75 ° C kwi-polyethyl insulated conductors kunye ne-90 ° C kwii-conductor ezidibeneyo kwi-600V okanye isigaba esingaphantsi kwisigaba.

Ulwakhiwo

Intambo enye ene-AAAC conductor, i-3-layer extruded shield kunye nenkqubo yokugubungela, equlethwe yi-semiconducting semiconducting i-thermoplastic conductor shield, kunye ne-2-layer covering.
Umaleko wangaphakathi ogqumayo yi-polyethylene ephantsi, ephakathi okanye ephezulu (LDPE, MDPE okanye i-HDPE), ngelixa umaleko wangaphandle unokumelana nomkhondo we-polyethylene ephakathi okanye ephezulu yoxinaniso (TK-MDPE okanye TK-HDPE).
Zonke iileya zidityaniswe kunye.

IKondi:
I-AAAC

IKhoki Shield:
Isikhuseli se-semiconducting semiconducting eyongeziweyo se-thermoplastic esikhulula ngokukhululekileyo kwi-conductor kwaye siboshwe kwisigqubuthelo.

Isigqubuthelo sangaphakathi nangaphandle:
I-2-layer low-, medium- or high-density polyethylene covering (LDPE, MDPE okanye HDPE), apho umaleko wangaphandle uxhathisa umkhondo (TK-MDPE okanye TK-HDPE).Zonke iileya zidityaniswe kunye.Umaleko ongaphandle uya kuba mnyama okanye ngwevu, ukumelana nokukhanya kwelanga kunye nokumelana nemikhondo.

I-ASTM 25kV ye-Space ye-Aerial Cable ye-SAC yaMandla oMntla we-SAC I-ACSR i-3-layer ekwaziyo ukumelana ne-Track XLPE (2)

Imigangatho

Ezi ntambo zenziwa kwaye zivavanywe ukuhlangabezana okanye ukugqitha le migangatho ilandelayo:
