Kutheni i-nyy sybs yindawo yokuhamba-hamba kwizicelo zokwakha

Xa kufikwa kwo ukhuseleko lomlilo kwizakhiwo, ukuba neentambo ezinokuthenjwa kubalulekile. Ngokwe-Eurocable, abantu abangama-4,000 bafa minyaka le eYurophu ngenxa yemililo, kwaye i-90% yale mililo yenzeka kwizakhiwo. Oku kugqabhuka kwezibalo eziqaqambileyo kuphela ukuba ibaluleke kangakanani ukusebenzisa iintsimbi ezinganyangekiyo zomlilo ekwakhiweni.

I-nyy scobs sisisombululo esinjalo, sinikezela ngokuchasene nomlilo ogqwesileyo ecaleni kwezinye izinto ezinomtsalane. I-TÜV-iqinisekiswe kwaye isetyenziswa ngokubanzi iYurophu yonke, ezi ntambo zilungele izakhiwo, iinkqubo zokugcina amandla, kunye nezinye iindawo ezifuna izinto. Kodwa yintoni eyenza i-nyy cable inokuthenjwa? Kwaye yintoni umahluko phakathi kwe-NYY-J kunye ne-NYY-O? Masiyiphule phantsi.

Zithini iintambo zenyy?

Ukwaphula igama

Igama elithi "nyy" libonisa kakhulu ngesakhiwo sentambo:

• Nimele i-coper yobhedu.
• Yimele ukufudumala kwe-pvc.
• YIkwabhekisa kwi-PVC engaphandle.

Le nkqubo yokuqonda ilula igxininisa iingxwaba ezimbini ze-PVC ezenza ukufunyanwa kwentambo kunye nokukhubazeka okukhuselayo.

Inkcazo ngokujonga

• I-NYY-O:Ifumaneka kwi-1C-7C x 1.5-95 I-MMT.
• Nyy-J:Ifumaneka kwi-3C-7C x 1.5-95 I-MMT.
• I-voltage enqwenelekayo:U₀ / U: 0.6 / 1.0 kV.
• I-Voltage yoVavanyo:I-4000 V.
• Iqondo lokushisa:-5 ° CA ukuya kuthi ga kwi-50 ° C.
• Iqondo lokushisa elisigxina:-40 ° C ukuya kwi-70 ° C.

Ukusetyenziswa kwe-PVC i-insultions kunye ne-sheang inika i-nyy yeentambo eziguquguqukayo. Oku kwenza ukuba bakwazi ukufaka, nkqu nakwimisebenzi yesakhiwo esinzima esinendawo eziqinileyo. I-PVC ikwabonelela ngomswakama kunye nokuchasana nothuli, nto leyo ebaluleke kakhulu kwiindawo ezinamagumbi angaphantsi kunye nezinye iindawo ezinomswakama.

Nangona kunjalo, kubalulekile ukuba uqaphele ukuba iintambo zenyy azilungelanga ufakelo lwekhonkrithi ezibandakanya ukuntywila okuphezulu okanye uxinzelelo olunzima.

Nyy-J Vs. Nyy-o: Yintoni umahluko?

Umahluko ophambili phakathi kobu buxoki bobabini kwisakhiwo sabo:

• Ny-jibandakanya ucingo oluhlaza oluhlaza oluhlaza. Oku kwenza ukuba kube lula kwizicelo apho kufuneka khona umhlaba ukubonelela ngokhuseleko olongezelelweyo. Uya kuhlala ubona ezi ntambo zisetyenziswa kufana phantsi komhlaba, kwiindawo ezingaphantsi kwamanzi, okanye iindawo zokwakha zangaphandle.
• Nyy-oayinaso ucingo oluphakamileyo. Isetyenziswe kwiimeko apho umhlaba ungafuneki okanye ususwe kwezinye iindlela.

Lo mahluko uvumela iinjineli kunye nombane ukuba bakhethe intambo efanelekileyo kwiprojekthi nganye.

Ukuchasana komlilo: kuvavanywa kwaye kungqinwa

Iintambo zenyy zaziwa ngokuchasene nomlilo, kwaye ziyahlangabezana nemigangatho engqongqo yehlabathi:

• IEC60332-1:
  Lo mgangatho uvavanya ukuba intambo inye ixhathisa njani umlilo xa ubeka ngokuthe nkqo. Uvavanyo oluphambili lubandakanya ukulinganisa ubude obunganyangekiyo kwaye ujonge ukuthembeka komhlaba emva kokufumana amadangatye.
• IEC6050502-1:
  Lo mgangatho we-voltage ye-cable ephantsi igubungela iimfuno zobugcisa ezifana neereyithingi ze-voltage, imilinganiselo, izixhobo zokufaka, kunye nokuxhathisa ubushushu kunye nokufuma kubushushu.

Le migangatho iqinisekise ukuba ii-nyy zenyoka zinokwenza ngokuthembekileyo, nokuba ziimeko ezinzima.

Zisetyenziswe phi iintambo zenyy?

Iintambo zenyy ziguquguqukayo kwaye zinokusetyenziswa kuluhlu olubanzi lwezicelo:

1. UQHAGAMSEBENZI
   Zigqibelele kwi-Wiring ngaphakathi kwizakhiwo, zibonelela ngokuqina kunye nokhuseleko lomlilo kwiiprojekthi zokuhlala nezorhwebo.
2. Ukufakelwa okungaphantsi komhlaba:
   I-PVC yabo ye-PVC iyenza ilungele ngokuthe ngqo ngqo ngaphantsi komhlaba, apho bakhuselwa ngumswakama kunye ne-corosion.
3. IZIDLA ZABASEKHAYA:
   Ngomntu oxineneyo, i-nyy cabs inokumelana nothuli, imvula, kunye nezinye iimeko ezinzima ezifumaneka kwiindawo ezingaphandle.
4. Iinkqubo zokuGcina amandla:
   Kwisisombululo semihla ngemihla, njengeenkqubo zokugcina ibhetri, iintambo zenyy qinisekisa ukuhanjiswa kwamandla kwaye kufanelekile.

Ukujonga phambili: ukuzibophelela kuka-Winpower

Xa siwile, sihlala sizabalazela ukufikelela kwiimfuno zokuvela zabathengi bethu. Ngokwandisa amatyala okusebenzisa iintambo zenyy kunye nokuphuhlisa iimveliso ezintsha, sijonge ukucoca izithintelo kwinkqubo yothutho lwamandla. Nokuba izakhiwo, ukugcina amandla, okanye iinkqubo zethu, injongo yethu kukubonelela ngezisombululo zengcali ezinikezela ukuthembeka, ukhuseleko, kunye nokusebenza.

Ngeentambo zethu zenyy, awukufumana nje imveliso-ufumana uxolo lwengqondo kwiiprojekthi zakho.
