Kutheni i-PVC-Insulated BV Wire iyisiseko soQhagamshelo oluKhuselekileyo lweTerminal

Icandelo 1: Yintoni i-BV Wire? Inkcazo eQhelekileyo

Ulwakhiwo oluqhelekileyo:

• Umqhubi: Ubhedu oluqinileyo okanye oluxineneyo olufakwe kwi-Annealed (Udidi 1 okanye Udidi 2, ngokwe-IEC 60228)

• Ubushushu: Uhlobo lwe-PVC A, B, okanye C (kuxhomekeke kumlinganiselo wobushushu kunye nokusetyenziswa)

Amacandelo aqhelekileyo:0.5 mm² ukuya kwi-10 mm² (eyona nto ifanelekileyo kwi Ibhloko yesiphelo uqhagamshelo ngaphakathi kwiiphaneli zolawulo kunye neebhokisi ze-junction)

Uvavanyo lweVolthi:450/750 V (eyona ixhaphakileyo) okanye 300/500 V

Uvavanyo lobushushu:Ngokwesiqhelo -15°C ukuya ku +70°C kwi-PVC eqhelekileyo (iiklasi ezikhethekileyo ziyafumaneka: -40°C ukuya ku +105°C)

Ngokungafaniyo neengcingo eziguquguqukayo (i-RVV, i-RV), ingcingo ye-BV ine-ukujiya, ubushushu bePVC obunzimakunye nomqhubi oqinileyo. Oku kuyenza ilungele:

• Iingcingo ezisisigxina ezizinzileyo ngaphakathi kwiiphaneli zombane

• Ukufakelwa kweentambo kwiibhokisi zokusasaza, ii-switchboards, kunye nezixhobo zasekhaya ezizinzileyo

• Uqhagamshelo kwiibhloko zesiphelo zohlobo lweskru kunye nohlobo lwentwasahlobo apho kufuneka khona ii-conductors eziqinileyo okanye ezixineneyo

  Icandelo 2: Kutheni i-PVC - kwaye kutheni umgangatho we-PVC ubalulekile

  Malunga nama-60% eengxaki zokungasebenzi kakuhle kweentambo ezibangelwa ziingxaki zokwambathisa ubushushu zibangelwaukwenziwa kwePVC okungekho mgangathweni, hayi ithusi. Nantsi into ekufuneka ijongwe ngabathengi abaziingcali:

  2.1 Umxholo weplastiki kunye nokufuduka
  I-PVC ekumgangatho ophantsi inee-plasticizers ezininzi. Ekuhambeni kwexesha, ii-plasticizers ziya kwiindawo zokugcina iibhloko (ingakumbi i-PA66 okanye i-PC), nto leyo ebangela ukuqhekeka okanye ukuthamba kwebhloko yokugcina iintsimbi. I-Yueqing Gaopeng Electric ivavanye iintambo ze-BV kubathengisi abangaphezu kwama-40 – singakuxelela oku:ukufuduka akubonakali de kutshabalalise iphaneli.

  2.2 Isalathisi seoksijini (ukungavuthi komlilo)
  I-PVC eqhelekileyo inomlinganiselo weoksijini ongama-26–30%. Intambo ye-BV esemgangathweni kufuneka iphumelele uvavanyo lwelangatye elithe nkqo lwe-IEC 60332-1. Kwiimvavanyo zethu zelebhu, i-PVC engalunganga iyaqhubeka nokutsha emva kokuba ilangatye lisusiwe - umngcipheko womlilo ngqo.

  2.3 Ukumelana nokuguga okushushu
  Ngokwe-IEC 60227, i-PVC insulation kufuneka imelane novavanyo lokuguga lweentsuku ezisi-7 kwi-80°C (kwi-70°C wire rated). I-PVC engaphantsi komgangatho iyaqina kwaye iyaqhekeka ngaphantsi kweentsuku ezi-3 phantsi kwemeko efanayo, nto leyo ekhokelela kwi-short circuits.

  2.4 Uvavanyo lokugoba okubandayo
  Ukuze ithunyelwe eYurophu okanye eMntla Melika, ucingo lwe-BV kufuneka ludlule kwi--15°C ebandayo egobile (okanye -25°C kwiindidi ezikhethekileyo). I-PVC engabizi kakhulu iba buthathaka njengeglasi engaphantsi kwe-0°C - akunakwenzeka ukuba ifakwe ngokukhuselekileyo ebusika okanye kwiindawo ezibandayo.

  Icandelo 3: Indlela i-BV Wire esebenzisana ngayo neeTerminal Blocks – Umbono wobuNjineli

  Oku kubalulekile kuye nawuphi na umthengi othenga iingcingo kunye neeterminal (nokuba zivela kubaboneleli abahlukeneyo). Iingcingo zeBV ezingalunganga zinokubangela ukusilela kwentsimi ye-terminal block:

  3.1 Ukuhambelana kweklasi yomqhubi

  • Uninzi lwee-terminals zohlobo lwe-screw (umz., i-Gaopeng T-Series yethu) zamkela zombini ii-conductors eziqinileyo (zeKlasi 1) kunye nezi-stranded (zeKlasi 2).

  • Iiterminals zohlobo lwentwasahlobo zithanda iClass 5 exineneyo okanye eguquguqukayo – kodwa uninzi lweentambo zeBV ziqinile.

  • Umzekelo wokungangqinelani:Ukusebenzisa i-BV eqinileyo eyi-4mm² kwisiphelo se-spring-clamp esenzelwe ucingo olunemicu emincinci kukhokelela ekubambeni nasekutsaleni okungathembekanga.

  3.2 Ubude kunye nokuchaneka kokuhluba
  Ubukhulu bokugquma kwePVC buyahluka. Intambo yeBV eqhelekileyo ngokwe-GB/T 5023.3 inobukhulu obuchaziweyo bokugquma (umz., 0.8mm kwi-2.5mm²). Nangona kunjalo, iingcingo ezininzi ezingabizi kakhulu zine-insulation encinci okanye engalinganiyo. Isiphumo: nokuba kukukhupha kakhulu (ukuveza ubhedu oluninzi, okubangela ii-short circuits) okanye ukukhupha ngaphantsi (i-PVC ebambeke ngaphakathi kwi-terminal, okubangela ukumelana okuphezulu).

  3.3 Umqhubi ojikelezayo xa kuthelekiswa nowecandelo
  Ucingo lwe-BV olusemgangathweni lune-conductor ejikelezayo ngokwenene. I-BV ekumgangatho ophantsi isebenzisa ubhedu olugoqwe ngokutsha olunobubanzi obungalinganiyo, olungenakuhlala kakuhle ngaphakathi kwe-clamping joke ye-terminal block. Oku kubangelaindawo yokunxibelelanaendaweni yokudibana komgca – ukwanda kwama-300% kokumelana nokudibana.
