Incazelo Yemodeli: "PH" ikhombisa indandatho yesandiso, futhi "7" ikhombisa umthwalo ophukayo ongu-70kN.
Impahla: Yenziwe ngensimbi enendawo eshisayo-edipha uthayela ukuze ikwazi ukumelana nokugqwala futhi ifaneleke ezindaweni zokusebenza zangaphandle ezinokhahlo.
Isakhiwo: Ngokujwayelekile-indandatho efojiwe yocezu olulodwa, efana ngesimo sendandatho elengayo emise oku-U{1}, kodwa izimbobo zokuxhuma ekugcineni zingaklanywa ngendlela ehlukile ukuze kufakwe izingxenyekazi zekhompuyutha ezihlukene nokulungiswa kobude.
Ubukhulu obuyinhloko: Ububanzi bendandatho 20mm, ububanzi bembobo 16mm, ubude bendandatho 80mm.
Amapharamitha wezobuchwepheshe: Umthwalo ophulayo ongu-70kN, isisindo esicishe sibe ngu-0.4kg.
Isicelo: Isetshenziselwa ukuxhuma izintambo ze-insulator ku-hardware, phakathi kwama-clamp nezintambo ze-insulator, naphakathi kwamakhondaktha ombani nemibhoshongo yezigxobo. I-Hardware yokuxhumana yendawo yonke.
PH-7 indandatho yesandiso ijwayele ukubizwa ngokuthi PH-0780, lapho okuthi "07" imele umthwalo ophukayo ongu-70 kN futhi "80" isho ubude bendandatho obungu-80 mm. Ikhiqizwa ngezinqe zensimbi eziyindilinga{12}ezishiselwe noma zenziwe ngomgunyathi njengesiqephu esisodwa, sakhe isakhiwo esimise okuyindandatho. Iziphetho zendandatho yokunwetshwa zingaxhunywa kwezinye ihadiwe, ngezikulufo zokuxhuma ziqondaniswe ngendlela efanayo, ziyenze indandatho ehambisanayo. Indawo enothayela ithuthukisa ukumelana nokugqwala futhi inwebe impilo yayo yesevisi. Njengokuxhumanisa okumise okwendandatho, kuvame ukusetshenziselwa ukuxhuma izintambo ze-insulator ku-hardware, phakathi kwama-clamp nezintambo ze-insulator, naphakathi kwamakhondaktha ombani nemibhoshongo.
Abasebenzisi bokuqala-beringi yesandiso ye-PH-7 bayelulekwa ngokukhethekile ukuthi bazijwayeze nokucaciswa kwayo kokusetshenziswa ukuze kuqinisekiswe ukufakwa okushelelayo.
Umkhawulo Womthwalo
Nakuba umthwalo ophukayo wendandatho yesandiso ye-PH-7 ingu-70kN, umthwalo wangempela wokusebenza kufanele ube Ngaphansi noma ulingane no-49kN, omele u-70% womthwalo ophukayo.
Ukuhambisana nokufaka
Amabhawodi kumele aqiniswe ngamantongomane aphindwe kabili ukuvikela ukuxega. Uma kukhwelana -nobakaki omise okwenkomishi, imvume kufanele ibe Ngaphansi noma ilingane no-1mm.
Contraindications kwezemvelo
Izinguqulo ze-cast iron zivinjelwe ezindaweni ezisogwini nezimboni. -Izinguqulo zengxubevange yezinga lokushisa eliphansi kufanele zikhethelwe izindawo ezingaphansi -20℃.
Indandatho yesandiso ye-PH-7 isetshenziswa ngokuyinhloko njengesixhumi emigqeni yamandla, nalezi zinhlelo zokusebenza ezilandelayo:
Isinxephezelo Sokuxhumana
Ukunweba ukuxhumeka phakathi kwezintambo zesivikelo naphakathi kwezinsimbi nezinsimbi zesivikelo ukuze kunxeshezelwe izikhala zokufakwa noma ukulungisa ukuchezuka kobude.
Imigqa Yokudlulisa
Izixhumi zokushintsha phakathi kwezintambo zokumiswa kanye nezintambo ze-tension ukuze kudluliswe imithwalo yemishini.
I-Pole Tower Transposition
Kufakwe ezintanjeni ze-tension insulator ukuze kuhlangatshezwane nezidingo zokucaciswa kukagesi zama-jumpers embhoshongweni.
Okujwayelekile okushisayo-i-dip galvanized alloy steel iqinisekisa ukumelana nokugqwala ngesikhathi sokusebenza. Nokho, izindandatho zokunweba ezinezijobelelo zika-"Z" zinqatshelwe ukusetshenziswa ezindaweni ezibola kakhulu.
PH-7 indandatho yesandiso ngokuvamile inempilo yesevisi yeminyaka engu-15-20. Nokho, ngokusetshenziswa isikhathi eside, ukuphila kwayo kuzophela ekugcineni. Ngakho unquma kanjani uma indandatho yesandiso idinga ukushintshwa? Cabangela izici ezintathu ezilandelayo:
Ukugqwala ukujula
Lapho ukugqwala kudlula i-1mm, ungqimba lwezinc lonakaliswa, kusheshisa ukugqwala kwensimbi.
Ukuguquguquka
Uma ukuguga komzimba okuyinhloko kudlula u-5%, iringi izogoba ngaphansi kwengcindezi noma ukucindezelwa, noma indawo yokungena izophuma iyindilinga.
Ukushisa-okuphansi
Uma amazinga okushisa angaphansi kokuthi -20℃engaphansi -20℃, ajwayele ukuphuka uma ingxubevange yezinga lokushisa eliphansi ingasetshenziswa.
Amashadi ashisayo: indandatho ye-ph-7, i-China ph-7 abakhiqizi bendandatho yesandiso, abahlinzeki, imboni
