Kubva pakuonekwa kwayo, iyo PT inogadzirisa mahwendefa ine yakapusa yakareruka chimiro, iyo zvakare inotemesa yayo yakapusa yekuisa maitiro. Hapana michina yakaoma inodiwa panguva yekuisa, uye inogona kuwana chaiyo yakakodzera. Saka inoiswa sei?
Kugadzirira: Kutanga, tarisa tarisa mahwendefa eP PT, kusanganisira kuona kuti hapana ngura, deformation, kuputika, kana kukanganisa pamusoro pepamusoro; kuti tambo hadzina kuvharwa; uye kuti zinc coating is intact. Tarisa chigadzirwa modhi, yakatarwa mutoro, uye gadziriso renji, uye shandisa yakakodzera wrench.
Kuiswa: Pukuta ndiro yakachena nemucheka kuti ubvise guruva nemafuta, uye shandisa zvishoma zverust inhibitor. Batanidza PT inogadzirisa mahwendefa kune insulator tambo uchishandisa mabhoti, simbisa mabhaudhi, tenderedza gadziriso screw, uye gadzirisa kureba kuti uve nechokwadi chekuti kunyangwe kushushikana uye kusarerekera pane insulator tambo. Shandisa chipanera kuomesa mabhaudhi kune yakatsanangurwa torque, kuve nechokwadi chekubatana kwakachengeteka pasina kusununguka. Chengetedza ndiro inoronga panzvimbo, uchivimbisa kuti hapana kutsauka.
Panguva yekuisa, dzivisa kurova chigadzirwa nechisimba kudzivirira kukanganisa kunyatsogadziriswa. Kana uchisimbisa mabhaudhi, shandisa simba zvakaenzana kudzivirira simba rakawandisa kune rimwe divi, izvo zvinogona kukanganisa tambo. Dzivisa kuisirwa mumamiriro ekunze asina kunaka semvura kana mhute, uye kudzivirira hunyoro hunosara kubva mukukonzera ngura.
PT inogadziridza mahwendefa anogona kugadzirwa emhando dzakasiyana panguva yekugadzira, uye zvinhu zvinowanzokanganisa mashandiro uye anoshanda mamiriro. Pazasi, takanyora ruzivo rwakakodzera pazvinhu zvakajairika kuti zvikubatsire kuita sarudzo yako.
| Material | Mechanical properties | Corrosion resistance | Mari yekupinda | Applicable Scenarios | Kungwarira pakushandisa |
| Kabhoni simbi (Q235B) | Pazasi (anenge 235 MPa) | Kazhinji, anti{0}}corrosion treatment inodiwa. | Low | Mitoro yakareruka (Isingasviki kana kuenzana ne50kN), zvikamu zvechipiri, mumamiriro ezvinhu ane bhajeti shoma uye nzvimbo dzakaoma. | Kupisa-dip galvanizing kana kumwe kunoda-mishonga yecorrosion kunodiwa; dzivisa kushandiswa munzvimbo dzine mwando kana dzinoora. |
| Yakakwirira-simbi yakasimba (Q355B) | High (inenge 355 MPa) | Kazhinji, anti{0}}corrosion treatment inodiwa. | Pakati | Applications involving high loads (>50kN) nemutoro mukuru-zvinotakura zvinhu, uko mutengo nemafambisirwo anofanirwa kuenzana. | Simba repamusoro rinobvumira maprofiles akaonda, asi kudzivirira ngura kuchiri kukosha. |
| Simbi isina tsvina (304) | Pakati (yakafanana nekabhoni simbi) | Zvakanaka, hapana imwe anti{0}}kuora inodiwa. | High | Kumaapplication ane mitoro yakaderera asi ichida kuchengetedzwa necorrosion, kana panobvumirwa bhajeti nekugadzirisa-pachena kushanda. | Inodhura uye inokodzera kunyorova, kwakavhurika-mhepo, kana nharaunda inoora. |
Senyanzvi yePT inogadziridza mahwendefa, isu tinotenda kuti vashandisi vanofanirwa kutarisisa kuenderana, kuvimbika kwekuita, uye kutevedzera zviyero zvekugadzira zvepasirese pavanenge vachitenga. Pazasi, isu tichatsanangura izvi zvakadzama:
Tsanangudzo
PT anogadzirisa mahwendefa anouya mumhando dzakasiyana-siyana uye zvakatemwa, senge PT-7, PT-10, uye PT-12, ayo akajairika. Kuti unzwisise zviyero zvinoenderana, unogona kukumbira chaiwo dimensional dhirowa kubva kumugadziri.
Scene
Nzwisisa chiyero chevoltage yendima yekushandisa, ingave yakaderera voltage kana yakakwira voltage, nzwisisa mhando yetambo ye insulator uye mamiriro ekushushikana, uye tsanangura mamiriro emutsara uye nzira yekubatanidza kumugadziri.
Mitemo
Ingave inoenderana nemitemo yenyika, ingave yakapfuura CE, UL uye zvimwe zvitupa, uye paunenge uchitaurirana, unofanirwa kubvunza nezve mutengo weFOB/CIF weiyo modhi chaiyo, pamwe nehuwandu hwekuraira huwandu, kusanganisira kurongedza uye nyaya dzekufambisa;
Mapuleti ePT anogadziridza anonyanya kushandiswa seakakosha ekubatanidza hardware mumasisitimu emagetsi uye anogona kushandiswa kune akasiyana siyana ekufambisa magetsi-ane hukama, kusanganisira zvinotevera:
High{{0}matambo ekufambisa magetsi
500kV kutapurirana mitsetse ine yakakwirira conductor tension, uye kaviri insulator tambo dzinoshandiswa kusangana nezvinodiwa zvesimba. Kana mutsara watendeuka, tambo mbiri dzichava nemasimba akasiyana. Iyo PT inogadzirisa mahwendefa inogona kugadzirisa kureba kwetambo kuita kuti insulator tambo dzitakure simba zvakaenzana, izvo zvinogona kuenderana nekutsauka kure panguva yekuvakwa kwemutsara.
01
Matanda emagetsi
Iyo danda uye insulator / pasi clamp yakabatanidzwa nesvikiro inobatanidza zvakasimba insulator uye pasi rinosungirirwa kune shongwe ruoko kana yekubatsira chimiro chedanda. Nekugadzirisa nzvimbo yemakomba ayo, inogona kuchinjirwa kune akasiyana maumbirwo saizi uye akarembera poindi zvinzvimbo, izvo zvinogona kunyatso kudzivirira njodzi dzekuchengetedza.
02
Kuvakwa kwegetsi remagetsi
Mitsetse yekugovera magetsi yemumaguta nemaruwa inoda kufamba pakati pezvivakwa nemigwagwa, uye nzvimbo yekumisikidza yakaoma. Nzira uye kona yekubatanidza yemitsara yakasiyana. PT inogadzirisa mahwendefa inogona kushandiswa kubatanidza insulator tambo ne clamps uye shongwe mune simba rekugovera network. Nekugadzirisa urefu kuti huenderane nemakwara akaoma, kugadzikana kwakagadzikana kwemitsara yekugovera magetsi kunogona kuvimbiswa, nokudaro kudzivirira kugadzikana kwemagetsi.

Special power transmission projects
Nzvimbo dzakakosha dzakaita senzvimbo dzemumhenderekedzo yegungwa, nzvimbo dzemaindasitiri, nenzvimbo-dzine mwando wakakwirira dzine makomo ane hunyoro hunodiwa zvakanyanya kuitira kusaita ngura uye kugadzikana kwemagetsi. Mushure mekunge pasi paiswa galvanized, kukora kwezvidziviriro nemhepo yegungwa munyu uye gasi rekubuda muindasitiri kunogona kudzikiswa, izvo zvinokwanisa kuchengetedza kugadzikana kwenguva refu-kwetambo yekubatanidza nekudaro kuderedza mari yekuzogadzirisa.
