Iyo pre-stranded waya inoshandiswa kubatanidza mafittings epamusoro pesimba conductor uye simba pamusoro pepamusoro cable terminal, kuturika uye kubatana. Iyo pre-tambo waya yakatanga kuonekwa muUnited States muma1940 nema1950. Chigadzirwa chepakutanga chaive spiral wire dziviriro yekusimbisa nzvimbo yewaya isina chinhu uye chinzvimbo chekuora kwemagetsi nekupisa kwearc. Mushure memakore ebudiriro, pre-yakamonyoroka waya fittings yakashandiswa zvakanyanya mukufambisa uye kugovera magetsi, optical fiber kutaurirana, njanji yemagetsi, cable TV, kuvaka, kurima uye mamwe minda.
Steel core aluminiyamu waya inoshandiswa zvakanyanya mu10 kV yekugovera network yewaya huru, ine nhevedzano yemabhenefiti esimba rakanyanya kusimba, kuita kwakanaka kwekudzivirira mheni, mutengo wakaderera, unoshandiswa zvakanyanya mumasabhabhu ekubatana kwemaguta uye tambo dzemagetsi dzekumaruwa. . Nekudaro, kana simbi yesimbi yealuminium conductor mutsara yakuvadzwa nekunze kwesimba kana mamiriro ekunze akaipa, zviri nyore kuve nepfupi yedunhu kukanganisa. Kana iyo yakasanganiswa pfupi yedunhu inoitika, waya ichaputswa. Kana mamiriro ezvinhu akadaro awanikwa, kurapwa kwakakodzera kwewaya kunofanirwa kupihwa munguva yekudzivisa kuenderera kwetambo dzisina kusimba dzinotungamira mukuderedzwa kwemagetsi uye magetsi emagetsi etambo.
Prestranded wire chigadzirwa che akati wandei-strand spiral wire prestranded. Zvinoenderana nehukuru hwechikamu chewaya, waya yehelix ine dhayamita yakatsanangurwa yemukati inotenderedzwa pamwe negwara rehelix kuti riite tubular mhango. Iyo pre-stranded wire is spiral yakaputirwa nekunze kwewaya. Pasi pekuita kwekumanikidza kwewaya, iyo spiral inotenderera kuita anchorage simba rewaya. Iyo yakakura tension yewaya, kusimba kunoita spiral uye kukura kwesimba rekubata. Iyo yakapfuura kugadzirisa prestranded waya inoshandiswa zvakanyanya mu35 kV uye pamusoro pemitsara, asi isinganyanyi kushandiswa mumitsara ye10 kV, uye inogona kungoshandiswa muchikamu chemutsara ne7% kana kushoma tambo yakatyoka uye kukuvara kwakakura hakuna kukura, uye. haigone kusvika pakusimbisa maitiro. Tension pretwisted waya yekubatanidza bha imhando nyowani ye pretwisted waya zvigadzirwa mumakore achangopfuura. Inoshandiswa semhando yekubatanidza chishandiso. Inogona kushandiswa kutsiva yakajairwa clamp pressure yekubatanidza pombi uye pressure pombi, inogona kushandiswa kubatanidza aluminium stranded waya, aluminium alloy stranded waya, simbi yepakati aruminiyamu yakasungwa waya uye dzimwe waya, kuti iwane yayo yepakutanga mechanical simba uye magetsi kushanda.
