Isikhokelo sokugqibela sokuKhetha uMmandla oMnqamlezo ogqibeleleyo kwiiCables zakho zeWelding

1. Intshayelelo

Ukukhetha indawo efanelekileyo ye-cross-sectional ye-welding cable ibaluleke kakhulu kunokuba unokucinga. Ichaphazela ngokuthe ngqo ukusebenza komatshini wakho we-welding kwaye iqinisekisa ukhuseleko ngexesha lokusebenza. Izinto ezimbini eziphambili omele uzigcine engqondweni xa usenza ukhetho lwakho yimali yangoku intambo inokusingatha kunye nokuhla kwamandla ombane ngaphezu kobude bayo. Ukungahoyi ezi zinto kunokukhokelela ekushiseni, ukusebenza kakubi, okanye umonakalo omkhulu wezixhobo.

Makhe sicazulule into ekufuneka uyazi ngendlela elula, inyathelo nenyathelo.

2. Imiba ephambili ekufuneka iqwalaselwe

Xa ukhetha i-welding cable, kukho izinto ezimbini ezibalulekileyo zokucinga:

1. Umthamo wangoku:
   • Oku kubhekiselele kubungakanani bangoku intambo inokuthwala ngokukhuselekileyo ngaphandle kokufudumeza. Ubungakanani bekhebula (ummandla we-cross-sectional) unquma ubuninzi bayo.
   • Kwiintambo ezimfutshane kuneemitha ezingama-20, unokujolisa kwi-ampacity kuphela, kuba ukuhla kombane akuyi kubaluleka.
   • Iintambo ezinde, nangona kunjalo, zifuna ukuqwalaselwa ngononophelo kuba ukuxhathisa kwentambo kunokukhokelela ekwehleni kombane, okuchaphazela ukusebenza kakuhle kwe-weld yakho.
2. Ukwehla kweVoloji:
   • Ukuhla kwe-voltage kuba kubalulekile xa ubude bentambo budlula i-20 yeemitha. Ukuba intambo incinci kakhulu ngoku ithwalayo, ilahleko ye-voltage iyanda, ukunciphisa amandla ahanjiswe kumatshini we-welding.
   • Njengomthetho wesithupha, ukuhla kwamandla akufanele kudlule i-4V. Ngaphaya kweemitha ezingama-50, kuya kufuneka ulungelelanise ukubala kwaye mhlawumbi ukhethe intambo eshinyeneyo ukuhlangabezana neemfuno.

3. Ukubala iCross-Section

Makhe sijonge umzekelo ukuze sibone ukuba kusebenza njani oku:

• Masithi i-welding current yakho300A, kunye nomthwalo wexesha lomthwalo (usebenza kangaphi umatshini).60%. Umsinga osebenzayo ubalwa ngolu hlobo:
  $300A\times 60\%=234A300A\; \backslash \; amaxesha\; 60\backslash \%\; =\; 234A$

  300A×60%=234A

• Ukuba usebenza ngoxinaniso lwangoku lwe7A/mm², uzakufuna intambo enendawo enqamlezileyo:
  $234A÷7A/mm2=33.4mm2234A\; \backslash div\; 7A/mm²\; =\; 33.4mm²$

  234A÷7A/mm2=33.4mm2

• Ngokusekelwe kwesi siphumo, umdlalo ongcono kakhulu uya kuba yiYHH-35 intambo yerabha eguquguqukayo, onommandla onqamlezileyo oyi-35mm².

Le ntambo iya kusingatha okwangoku ngaphandle kokushisa kwaye isebenze ngokufanelekileyo ubude ukuya kwi-20 yeemitha.

4. Isishwankathelo se-YHH Welding Cable

Yintoni intambo ye-YHH?Iintambo ze-YHH ze-welding zenzelwe ngokukodwa ukudibanisa kwecala lesibini kumatshini we-welding. Ezi ntambo zomelele, zibhetyebhetye, kwaye zilungele iimeko ezirhabaxa zokuwelda.

• Ukuhambelana kombane: Banokusingatha i-AC peak voltages ukuya kuthi ga200Vkunye ne-DC ephezulu yombane ukuya kuthi ga400V.
• Ubushushu bokusebenza: Ubushushu obuphezulu bokusebenza bu60°C, ukuqinisekisa ukusebenza okuthembekileyo naphantsi kokusetyenziswa okuqhubekayo.

Kutheni iintambo ze-YHH?Isakhiwo esikhethekileyo seentambo ze-YHH zenza ukuba ziguquguquke, zilula ukuphatha, kwaye zixhathise ukugqoka kunye nokukrazula. Ezi zakhiwo zibalulekile kwizicelo ze-welding apho intshukumo rhoqo kunye neendawo ezixineneyo ziqhelekileyo.

5. Itheyibhile yokuchaza iCable

Apha ngezantsi kukho itafile ecacileyo yeentambo ze-YHH. Igxininisa iiparitha eziphambili, kubandakanywa ubungakanani bekhebula, indawo elinganayo ye-cross-sectional, kunye nokumelana nomqhubi.

Isixelela ntoni le theyibhile?

• I-AWG (i-American Wire Gauge): Amanani amancinci athetha iingcingo ezityebileyo.
• Ubungakanani obulinganayo: Ibonisa indawo enqamlezileyo kwi-mm².
• Ukuchasa iKondi: Ukuchasana okuphantsi kuthetha ukuhla kwamandla ombane amancinci.

6. IziKhokelo eziSebenzayo zokuKhetha

Nalu uluhlu lokukhangela olukhawulezayo lokukunceda ukhethe intambo efanelekileyo:

1. Linganisa ubude bentambo ye-welding.
2. Qinisekisa ukuba ubuninzi bangoku umatshini wakho welding uya kusebenzisa.
3. Qwalasela umyinge wexesha lomthwalo (usebenza kangaphi umatshini).
4. Khangela ukuhla kwamandla ombane kwiintambo ezinde (ngaphezu kwe-20m okanye i-50m).
5. Sebenzisa itheyibhile yokuchaza ukufumana owona mdlalo ubalaseleyo ngokusekwe kubuninzi bangoku kunye nobukhulu.

Ukuba uyathandabuza, kusoloko kukhuselekile ukuhamba ngentambo enkulu kancinane. Intambo etyebileyo inokubiza ngaphezulu, kodwa iya kubonelela ngokusebenza okungcono kwaye ihlale ixesha elide.

7. Isiphelo

Ukukhetha intambo ye-welding echanekileyo imalunga nokulinganisa umthamo wangoku kunye nokuhla kwamandla ombane ngelixa ugcina ukhuseleko kunye nokusebenza kakuhle engqondweni. Nokuba usebenzisa intambo ye-10mm² kwimisebenzi ekhaphukhaphu okanye intambo ye-95mm² kwimisebenzi enzima, qiniseka ukuba uyayitshatisa intambo kwiimfuno zakho ezithile. Kwaye ungalibali ukudibana neetheyibhile zenkcazo yesikhokelo esichanekileyo.
