Shandisa imwe kana kudzika kwekuisa kwaunoda kunopfuura 3.0 m, kana zvipingamupinyi zvekutakura zvichidzivirira kubata tsvimbo refu panzvimbo yacho, kana kana mamiriro evhu asina chokwadi uye uchida kuti kudzika kuwedzere zvishoma nezvishoma. Muchirongwa chedu cheAbuja, Nigeria, tsvimbo dzezvikamu dzakasvika 4.2 ohms pakadzika kwe6 m muvhu re laterite uko 2.4 m tsvimbo imwe chete yaiyera 28 ohms.
Kubatanidza tsvimbo yepasi yakarukwa (coupler) isimbi pfupi yemhangura ine tambo dzemukati kumativi ese. Unopinza chikamu chimwe chete chetsvimbo mumativi ese wosimbisa kusvika ku50–80 Nm nepanera. Coupler inofambisa simba rekutyaira kubva kuchikamu chepamusoro kuenda kune chezasi uye inochengetedza kuenderera mberi kwemagetsi. Coupler dzedu dzinoshandisa tambo dzemetric (M16 x 2.0 yetsvimbo dze5/8-inch, M20 x 2.5 yetsvimbo dze3/4-inch) dzine chamfered entries kudzivirira cross-threading—kugadzira patsva kwakaderedza mwero wekukundikana kwedu cross-threading ne70% mushure mekunge tanyora zviitiko makumi mana nenomwe muna 2021.
Matavi akaputirwa nemhangura anoshandisa electroplating inoenderera mberi iyo inogadzira chisungo chesimbi pakati pechikamu chemhangura nepakati pesimbi. Matavi akaputirwa nemhangura anogona kushandisa nzira yekubatanidza michina. Pakutyaira kwakadzika, chisungo chesimbi chinodzivirira kuparadzwa kana charova. Tinoedza nzvimbo yega yega yekugadzira nekuyedza kwe180-degree bend (100 mm radius): mhangura haifanirwe kutsemuka kana kutsemuka. Takakundikana bvunzo iyi kaviri mumakore matatu, nguva dzese dziri mbiri dzakateverwa nekudonha kwevoltage mumutsara wedu we electroplating.
Hapana muganho wehudzamu hwehunyanzvi chero bedzi ivhu richigona kupinda uye majoini ekubatanidza achiramba akasimba. Vatengi vedu vasvika 12 m mu tropical laterite (Democratic Republic of Congo) uye 9 m mujecha rerenje (Saudi Arabia). Muganho unoshanda unowanzova werudzi rwevhu—ivhu rine matombo rinogona kuda gomba repilot kana imwe nzira yekudzika pasi senge chemical grounding electrodes. Kune akawanda mapurojekiti, 3 kusvika 6 m yakakwana kuti iwane kudzivirira kwevhu kunodiwa.
50 kusvika 80 Nm yematanda e5/8-inch (14.2 mm); 60 kusvika 100 Nm yematanda e3/4-inch (17.2 mm). Gara uchichenesa tambo usati wabatanidza uye shandisa chipanera chetorque chakagadziriswa kana chiripo. Muna 2023, chirongwa cheDar es Salaam chakarasikirwa nezvikamu zviviri pasi pevhu apo vanoisa macouplers akasungwa nemaoko vasina chipanera—macouplers akasunungurwa panguva yekutyaira uye zvikamu zvakaparadzaniswa. Iye zvino tava kuisa kadhi re torque mubhokisi rega rega re sectional kit.
Ehe, iyi itsika yakajairika. Tanga netsvimbo imwe chete ye 1.5 kusvika 2.4 m yekutanga, wobva wawedzera zvikamu zvechikamu uchishandisa coupler kana uchida kudzika kwakawanda. Dhayamita yetsvimbo nechimiro cheshinda zvinofanirwa kuenderana ne coupler. Coupler dzedu dzinoenderana netsvimbo dzesimbi dzakajairwa dze 5/8-inch uye 3/4-inch copper-clad dzinoshandisa metric thread convention yakafanana, zvisinei nemugadziri.
Zvigadzirwa zvese zvinogadzirwa pasi peISO 9001:2008. Matavi edu esimbi akaputirwa nemhangura anosangana nezvinodiwa nehukobvu hwemhangura hweUL 467 (≥0.254 mm). Tinopa mishumo yekuedza simba rekudhonza, ukobvu hwemhangura, kuchena kwemhangura, uye kuvimbika kwebond kana zvakumbirwa. Kune mapurojekiti anoda zvitupa zvevamwe, tinoshanda nemarabhoritari ekuyedza ane mvumo kuti tipe magwaro anodiwa.
Bata Jane Yang kuti uwane matsanangudzo ezvigadzirwa, mienzaniso, uye mutengo wepurojekiti. Makore gumi nemanomwe eruzivo rwekugadzira, ISO 9001:2008 certification, tumira kunze kwenyika dzinopfuura makumi matanhatu.
