NYM (ikhebula): incazelo kanye nokubuyekeza

Lapho kwakhiwa noma ukulungisa banoma iyiphi into akuyona ngaphandle ebeka noma esikhundleni amanethiwekhi kagesi. Futhi ngokuqinisekile ukubaluleka kubalulekile yiyona brand ikhebula. imikhiqizo ye-wiring ingaphakathi akumelwe nje bagcine ngokufuna athobele zamanje esiphezulu, ekuhlukanisweni nabantu bakaJehova, ukushisa kuvunyelwe, kodwa izidingo zokuphepha umlilo.

NYM ikhebula design

Ethandwa kakhulu imikhiqizo ikhebula eminyakeni yamuva kuyinto NYM-ikhebula. Incazelo nezici tibalwe lapha ngentasi. Siqukethe babashayeli zethusi olulodwa noma multi-wire behlukene melonapolnennogo PVC. Anemibala ikhebula izintambo:

• 2-wire - black, blue;
• 3-core - oluhlaza-ophuzi, omnyama, blue;
• 4-wire - oluhlaza-ophuzi, omnyama, blue, onsundu ngaphansi;
• 5-wire - oluhlaza-ophuzi, omnyama, blue, onsundu, abamnyama.

Udonga lwangaphandle senziwa PVC melonapolnennogo. Emgodleni umbala - grey ukukhanya. igobolondo Ubude kuyinto extruded melonapolnennoy zenjoloba.

wokugubha

Uhlobo ekubizweni imikhiqizo ikhebula iqukathe izinhlamvu NYM, okubonisa:

• N - ikhebula okujwayelekile (ngezigaba German);
• Y - Kwemihlambi PVC (PVC e incazelo European);
• M - khona emgodleni yangaphandle.

Ngaphezu kwalokho hyphenated izimpawu osetshenziswayo J - khona wire green-ophuzi, noma mayelana - umkhiqizo ngaphandle emithanjeni ophuzi. Ngemva kwalokho ucacise inombolo kanye nesigaba cross, yokusebenza voltage.
Ngokwesibonelo akubiza 3h2,5-0,66 NYM-J simele ikhebula ejwayelekile nge emgodleni yangaphandle PVC ukwahlukanisa nge ezintathu umqhubi cross-ingxenye 2.5 mm² ngoba voltage ka 0.66 kV.
I kophawu abakhiqizi ezifuywayo, ihambisana nemigomo ye GOST R 53769-2010 lokhu ikhebula ephawulwe NYM 3h2,5 kulungile (N, PE). Lapha "o" - umqhubi okuqinile (okukanye "m" -mnogoprovolochnaya) "k" - round wahlala, N futhi PE - zero futhi umqhubi zokuzivikela.
It is wayevame ukuthi ikhebuli wire NYM. Ikhebula - kuyini? Nenikezwa esimweni ejwayelekile, inikeza: "Ikhebula umkhiqizo ehlanganisa eyodwa noma babashayeli ukushisa namakhaza ngaphezulu ebiyelwe igobolondo." Ngakho-ke, ngokuthi kahle NYM hhayi ucingo kanye cable.

Amapharamitha main

Ukucaciswa kobuchwepheshe ibalulekile kokubili ochwepheshe nekhaya izingcweti:

• voltage Kulinganiswe ngo - 0.66 kW.
• Operating okushisa - kusuka -50 kuya +50 ⁰ C.
• Ubuncane Strip lokushisa - -5 ⁰ C.
• Ubuncane ukugoba engaba - hhayi 4 izikhathi esingaphansi ububanzi ikhebula.
• inkonzo nokuphila - iminyaka engu-30.
• Inombolo cores - kusuka 1 kuya 5.
• Ububanzi izigaba cross - kusuka 1.5 kuya 35 kwangu isikwele
• Okufakiwe - amatheku 25, 50 m, noma isigubhu by 500 m.

Futhi-ke, ipharamitha ezibaluleke kakhulu kabelya- wamanje yayo ovumelekile. Okunqumayo kuncike babashayeli kwesigaba, indlela napkin lokushisa ngaphandle. Ukuze ukulinganisela anolaka udinga ukusebenzisa idatha labalwa kusukela EMP:

Kufanele kuqashelwe ukuthi ikhebuli kungenziwa kukhiqizwa ngokuvumelana nezindinganiso ze-European (German), GOST noma TU (ezibekiweko lobuchwepheshe). Kwakamuva akhiwa umenzi. Ngakho-ke, nemingcele ikhebula ezifana ukwahlukanisa ukushuba, ukubekezelelana sesigaba engu- zingahluka kusuka NYM abakhiqizi. Ikhebula izilinganiso, kuye ngokuthi umenzi, uthola okuhle nokubi yini ngakho.

Izinzuzo Ububi

Njenganoma yimuphi umkhiqizo, chips has NYM-ikhebula. Incazelo izici zayo lapha ngenzansi:

• Ikhwalithi ephezulu ukwahlukanisa izinto. PVC plasticized ukushisa ukumelana, ayisekeli amandla omlilo, kuba nezimo.
• Ubulula kokuthenga. Ngenxa yamathebhu athambile ikhava zokuzivikela kungenziwa kalula zisuswe ngaphandle kokulimaza zamanje esithwele umqhubi ukwahlukanisa.
• izintambo Quality conductive athambile zethusi wire. basonta Kalula ukwakha uxhumano eliphezulu.
• Khanyisa grey umbala udonga lwangaphandle ekahle kakhulu wokugubha ipeni obungangenhloko kakhanjana noma umaka phakathi nokufaka.
• ukuphila isikhathi eside, standard iminyaka engu-30.
• Ikhebula akunconyelwe ukufakwa ongaphandle, amelana elangeni.
• kwesigaba lokungafani wahlala licaciswe ku wokugubha. Sivame ukuzwa "ukuthenga NYM-ikhebula, siyini lesi umbhedo?" Futhi konke silula: imikhiqizo ngaphansi kwalesi brand namuhla yingcweti kokubili izitshalo ikhebula zasekhaya, futhi eduze phesheya. Futhi akubona bonke luqoqwe namazinga German noma ngisho izivakashi zethu.

isicelo

NYM - ikhebula kabani ncazelo ibonisa ukuthi senzelwe ukufakwa olulodwa fixed endlini kuphela. Ukubeka ngendlela ugongolo ngaphandle ukuvikelwa okungeziwe akuvunyelwe. Futhi, ungasebenzisi leli ikhebula brand kuxhumana ngqo namatheminali zikagesi, i intambo isandiso. Izindlela kubekwa enganyelwe nehhanisi kanye neziqondiso kuzo kagesi umlilo imibhalo ngokuphepha. Ivumela laying amakhebuli e izimbotshana neziteshi Udonga panel, ukusika anemifantu ezindongeni e ungqimba usimende ku amashubhu kanye Amapayipi amakhulu kagesi. It wagomela ngokuthi kungenzeka NYM izintambo kwaholela ngokukhululekile ezindongeni sokhuni, kodwa akuyona. Kagesi imithetho Ukufakwa zibonisa ngokucacile ukuthi kungenzeka laying elivuliwe kuphela amapayipi noma Amapayipi, futhi kufihlwe ngaphakathi kwezindonga ngokhuni - e metal amapayipi kwanoma iyiphi wire, kuhlanganise NYM. Ikhebula, okuyinto has izithombe ngezansi, ukukhwezwa kahle.

ikhebula Ukukhethwa

Ngo emakethe yasekhaya ngokuyinhloko imikhiqizo ikhebula zokukhiqiza yasekhaya noma "engaziwa" isitshalo. Lapho ekhetha look for the mshini kwanoma iyiphi sina ikhebula isitshalo uvele logo yakho noma igama. Lena okungenani ubuncane, kodwa namanje isiqinisekiso izinga.

• Ngezinye izikhathi abathengisi ukuncoma esikhundleni ukusebenzisa SHVVP NYM, sts. Ungakuvumeli lokhu Iqhinga: SHVVP futhi PVA - ke izintambo, NYM - ikhebula. Incazelo ulawula inkambu ohluke ngokuphelele isicelo. Izintambo - uxhumano endlu Imishini kanye nezintambo zokunweba, ikhebula - I-wiring esinqunyiwe.
• Sebenzisa izintambo lesithathu eziphilayo eluhlaza nephuzi ngoba umhlaba zokuzivikela.
• Lapho kukhethwa intambo cross-section engaqondiswa ngesincomo elula: ukukhanyisa - 1.5 mm², ngoba inethiwekhi zesifazane - 2,5 mm², ngoba endzaweni lephephile kagesi nge kuhhavini - 4-6kv.mm.
• Uma ungabaza ngokusebenza ikhebula -priobretite obuncane 1 imitha kwanele. Hlola flammability ikhebula - ukwahlukanisa akumelwe ukusekela self-amandla omlilo.
• Kuyinto uyelulekwa ukuhlola esigabeni cross. Uma kungekho i-mic, ungavele uvalwe nilimaza 10 ematfuba umqhubi angenalutho kwi ipensela. Bese ulinganise ubude obuyizinkulungwane umugqa ezivamile emazombezombe. Kwehlukanisa ngo-10, sithola ubukhulu langempela le wire.
