Inkcazo kunye nosetyenziso lwe-Aluminium conductor steel-reinforced (ACSR)

I-ACSR i-conductor okanye i-aluminium conductor yensimbi eqinisiweyo isetyenziselwa ukuhanjiswa kwe-overhead engenanto kunye nentambo yokuqala kunye neyesibini yokusabalalisa. Imisonto yangaphandle yi-aluminiyam yococeko oluphezulu, ekhethwe ngenxa yokuqhuba kakuhle kwayo, ubunzima obuphantsi, ixabiso eliphantsi, ukuxhathisa ukubola kunye nokuxhathisa ngoxinzelelo kumatshini. I-strand yeziko yintsimbi yamandla ongezelelweyo ukunceda ukuxhasa ubunzima bomqhubi. Intsimbi yomelele ngaphezu kwe-aluminiyam evumela ukwanda koxinzelelo lomatshini ukuba lufakwe kwi-conductor. Intsimbi ikwanayo ne-elastic esezantsi kunye ne-inelastic deformation (i-elongation esisigxina) ngenxa yokulayisha ngoomatshini (umz. umoya kunye nomkhenkce) kunye ne-coefficient ephantsi yokwandiswa kwe-thermal phantsi kokulayisha ngoku. Ezi zakhiwo zivumela i-ACSR ukuba igxumeke kakhulu ngaphantsi kwee-conductor ze-aluminiyam. Ngokwe-International Electrotechnical Commission (IEC) kunye neQela le-CSA (eyayisakuba yiCanadian Standards Association okanye i-CSA) ingqungquthela yamagama, i-ACSR ityunjwe i-A1/S1A.

I-alloy ye-aluminium kunye nobushushu obusetyenziselwa imicu yangaphandle e-United States naseCanada ngokuqhelekileyo i-1350-H19 nakwezinye iindawo i-1370-H19, nganye inomxholo we-99.5 +% we-aluminium. Ubushushu be-aluminium buchazwa sisimamva senguqulo ye-aluminium, kwimeko ye-H19 inzima kakhulu. Ukwandisa ubomi benkonzo yeentambo zetsimbi ezisetyenziselwa i-conductor core ngokuqhelekileyo zifakwe i-galvanized, okanye zifakwe nge-zinc ukukhusela ukubola. Ububanzi beentambo ezisetyenziselwa zombini i-aluminium kunye neentsimbi zetsimbi ziyahluka kwii-conductors ze-ACSR ezahlukeneyo.

Intambo ye-ACSR isaxhomekeke kukuqina kwe-aluminiyam; iqiniswa kuphela yintsimbi. Ngenxa yoku, ubushushu bayo obuqhubekayo bokusebenza bulinganiselwe ukuya kuma-75 °C (167 °F), iqondo lobushushu apho ialuminiyam iqala ukunyibilika kwaye ithambe ngokuhamba kwexesha. Kwiimeko apho kufuneka ubushushu bokusebenza obuphezulu, ialuminium-conductor steel-supported (ACSS) ingasetyenziswa.

Ukulala komqhubi kunqunywe yiminwe emine eyandisiweyo; Isalathiso "ekunene" okanye "ekhohlo" sokulala simiselwa ngokuxhomekeke ukuba sihambelana nomnwe ukusuka kwisandla sasekunene okanye sasekhohlo ngokulandelelanayo. I-aluminium engaphezulu (i-AAC, i-AAAC, i-ACAR) kunye nabaqhubi be-ACSR e-USA bahlala beveliswa kunye nomgca we-conductor wangaphandle kunye nesandla sokunene. Ukuya ngasembindini, umaleko ngamnye uneendawo zokubeka ezitshintshanayo. Ezinye iintlobo ze-conductor (umz. i-copper overhead conductor, i-OPGW, i-EHS yentsimbi) yahlukile kwaye inesandla sasekhohlo kwi-conductor yangaphandle. Amanye amazwe aseMzantsi Melika achaza ilele yesandla sasekhohlo yomaleko womqhubi wangaphandle kwi-ACSR yawo, ngoko ke ezo zilimele ngokwahlukileyo kunezo zisetyenziswa e-USA.

I-ACSR eyenziwe sithi inokuhlangabezana ne-ASTM, AS, BS, CSA, DIN, IEC, NFC njl njl.
