Thumela I-imeyili KithiNgemibuzo mayelana nemikhiqizo yethu noma uhlu lwamanani, sicela usishiyele i-imeyili futhi sizokuthinta kungakapheli amahora angama-24
AS 1222.1 GSW Galvanized Steel Cable Conductor SC/GZ Messenger Wire
LANDA IZINCAZELO ZESIKHATHI
Isicelo
Ikhondatha yensimbi eyenziwe ngensimbi i-SC/GZ yizintambo zensimbi ezikhangayo ezisetshenziselwa kakhulu ukusimamisa umthwalo wemishini embonini kagesi.
Izici
I-galvanized guy wire yenziwe ngensimbi ebulewe ngokuphelele enekhabhoni engu-0.6% ine-UTS engu-1.31-1.39GPa. Ifakwe insimbi noma ngenqubo ye-electrolytic ukunikeza isisindo se-zinc esingu-200-260g/m.2kucaciswe ku-AS 1222.1 ejwayelekile.
Ukupakisha
Ubude bokulethwa bunqunywa ngokucatshangelwa kwezinto ezifana nobukhulu bemigqomo ebonakalayo, izisindo zesigubhu, ubude be-span kanye nezinto zokuphatha.
Ukwakha
Izintambo zensimbi ezikhangayo ziboshelwe ngokugxilile futhi izendlalelo ezilandelanayo zinendlela ehlukile ye-lay, ungqimba olungaphandle kakhulu lusesandleni sokudla.
Uma kudingeka, ucingo olumaphakathi olukhudlwana (i-king wire) lufakwa ku-conductor.Ububanzi balolu cingo busekelwe ekucatshangelweni kwedizayini ye-conductor futhi ngokuvamile bukhulu ngo-5% kunezintambo ezizungezile.

Qaphela
Izici zokusebenza zikagesi eziboniswe ngenhla azinaki imiphumela kazibuthe ngakho-ke ziyalinganiselwa kuphela.
Izilinganiso zamanje zisekelwe kulezi zimo ezilandelayo:
• Izinga lokushisa lekhondatha likhuphuka ngaphezu kwe-ambient engu-40°C
• Izinga lokushisa lomoya we-ambient.engu-35°C emini yasehlobo noma u-10°C ebusuku basebusika
• Amandla emisebe yelanga aqondile angu-1000 W/m2 emini yasehlobo noma eyiziro ebusuku basebusika
• Sabalalisa amandla emisebe yelanga angu-100 W/m2 emini yasehlobo noma uziro ebusuku basebusika • Ukukhanya okuphansi okungu-0.2
