Yintoni iCopper Clad Steel Wire (CCS Wire)?

Ucingo lwentsimbi olugqunywe ngekopolo luyi-bimetallic composite conductivity equlathe isiseko sentsimbi (ngesiqhelo intsimbi ephantsi ukuya kwephakathi yekhabhoni) enomaleko wangaphandle ogqunywe nge-electroplated okanye ogqunywe nge-high-purity copper. Isiseko sentsimbi sibonelela ngamandla okutsalwa kunye nenkxaso yesakhiwo, ngelixa umaleko wekopolo—ngesiqhelo i-6–40% yendawo iyonke enqamlezileyo—uhambisa umbane.

Iinkqubo eziphambili zokuvelisa ziquka:

• • Ukufakelwa nge-Electroplating: Ubhedu lufakwa ngokulinganayo kumbindi wentsimbi ngenkqubo ye-electrochemical, ukuqinisekisa ukuba ubhedu luhlala luqinile kwaye lunamathelana ngokuqinileyo.
• • Isigqubuthelo (Isigqubuthelo): Umcu wobhedu usoloko usongwa kwaye ubotshelelwe ngesinyithi kumbindi wentsimbi, nto leyo eyenza ujongano olungenamthungo lwe-bimetallic.

Ngenxa yokuba imisinga ye-frequency ephezulu ihamba kumphezulu wangaphandle we-conductor (isiphumo sesikhumba), i-CCS wire ifikelela ekusebenzeni kokudluliselwa kwesignali okufana kakhulu ne-copper wire eqinileyo enobubanzi obufanayo, ngelixa inciphisa ukusetyenziswa kwe-copper ngama-50–70%.

I-CCS Strand Wire vs. Solid Copper: Zithelekiswa njani?

Xa kuvavanywa ii-conductors zegridi zokumisa umhlaba, iintambo ze-messenger, okanye ii-coaxial cable inner conductors, abathengi be-B2B badla ngokuthelekisa intambo ye-CCS strand kunye nentambo yobhedu eqinileyo. Olu thelekiso lulandelayo lubonisa umahluko ophambili:

Kwizicelo ezininzi zokumisa umhlaba, ukubopha, kunye nokuhambisa isignali, ucingo lwe-CCS strand lubonelela ngokulinganisela okufanelekileyo kokusebenza, ukuqina, kunye neendleko. Ubhedu oluqinileyo luhlala lukhetho lwezicelo ezifuna ukuhanjiswa okuphezulu (umz., izixhobo ezichanekileyo) okanye apho iikhowudi ziyiyalela ngokucacileyo.

Iintonga Zomhlaba Ezigqunywe Ngobhedu: Umqolo Weenkqubo Zomhlaba Ezithembekileyo

I-electrode yokumisa umhlaba yeyona nto ibalulekileyo phakathi kwenkqubo yombane nomhlaba. Ibonelela ngendlela ethintela umbane ukuba usasazeke ngokukhuselekileyo, ikhusela izixhobo kunye nabasebenzi. Iintonga zomhlaba ezigqunywe yikopolo—ezaziwa ngokuba ziintonga zomhlaba zentsimbi ezigqunywe yikopolo—ziphakathi kwezona zisetyenziswa kakhulu kwihlabathi liphela.

I-Xinchang Shibang yenza iintonga zomhlaba ezigqunywe ngobhedu ngokufaka ubhedu olucocekileyo oluyi-99.9% kwiintsimbi zentsimbi ezinekhabhoni ephantsi ezikumgangatho ophezulu. Iinkcukacha zobugcisa eziphambili ziquka:

Iintonga zomhlaba ezigqunywe ngekopolo zifanelekile kwiindawo ezahlukeneyo—ukusuka kwiimeko zomhlaba eziqhelekileyo ukuya kumhlaba omanzi, onetyuwa, okanye osebenzisa iikhemikhali. Zisetyenziswa kakhulu kwezi:

• • Izityalo zombane kunye nezitishi ezingaphantsi

• • Iinkqubo zombane kunye nemiqondiso kaloliwe
• • Izityalo zoshishino kunye nezakhiwo zepetrochemical
• • Ulwakhiwo lwezakhiwo zorhwebo nezindlu zokuhlala

Ukuwelda kwe-Exothermic: Ukudala uQhagamshelo oluhlala luhleli, olungenakumelana kakhulu nomhlaba

Kwanentambo yentsimbi egqunywe ngobhedu kunye neentonga zomhlaba ezikumgangatho ophezulu zisebenza kuphela xa ziqhagamshelwe. Ukuwelda kwe-exothermic (okwaziwa ngokuba yi-thermite welding) ngumgangatho ogqwesileyo wokudala iibhondi ezihlala zihleli, ezikumgangatho weemolekyuli phakathi kwee-grounding conductors.

Le nkqubo isebenzisa i-chemical reaction—eqhele ukuba phakathi komgubo we-aluminiyam kunye ne-copper oxide—ukuvelisa amaqondo obushushu angaphezulu kwe-1,400°C. Ubhedu olunyibilikisiweyo oluphumayo lungena kwi-graphite mold, lujikeleze ngokupheleleyo ii-conductors eziza kudibana. Nje ukuba ipholile, i-weld yenza unxibelelwano ne:

• • Ukumelana kombane okulingana okanye ongaphantsi kunee-conductors ngokwazo
• • Amandla oomatshini alingana namandla eentsimbi ezimbini ezidibeneyo
• • Ukumelana nokugqwala okugqwesileyo, nokuba kuphantsi komhlaba okanye kwiindawo zaselwandle
• • Akukho mfuneko yemithombo yamandla yangaphandle—ilungele ukufakwa okude

Ukuwelda kwe-exothermic kubaluleke kakhulu ekudibaniseni intsimbi egqunywe yi-copper clad kwi-copper ecocekileyo, i-copper kwi-galvanized steel, okanye i-copper kwi-cast iron. Yindlela yokudibanisa ekhethwayo echazwe kwi-IEEE 80 kwiinkqubo zokumisa umhlaba kwaye iyaqatshelwa yi-US National Electrical Code (NEC) §250.8 njengendlela eyamkelekileyo yokubopha i-grounding conductors.

Indlela yokukhetha ucingo lwentsimbi oluqinileyo lweCopper Clad oluchanekileyo kwisicelo sakho
