Pankhani ya kutentha kwa nthawi yayitali kwa ma cores carter, mitengo ya mphira nthawi zambiri imawerengedwa pa 65 ° Chloride (pvc) Kusindikiza kwa 70 ° C. Kwa mabwalo ofupikirapo (okhala ndi nthawi yayitali osaposa masekondi 5), kutentha kwambiri kovomerezeka ndi 160 ° C kwa pvc phost ndi 250 ° C kwa Xlpe C kwa XLPE.
I. Kusiyana pakati pa XLPE CEGS ndi CVC Nthanzi
1. Zingwe zotsika kwambiri (Xlpe) yolumikizidwa (chifukwa cha m'ma 1990s, tawonapo chitukuko champhamvu, tsopano ndikuwerengera theka la msika limodzi ndi polyvinyl chloride (pvc) chingwe. Poyerekeza ndi zingwe za PVC, xlpe zingwe zowonetsa zapamwamba zaposachedwa, zamphamvu zochulukitsa, komanso nthawi yayitali kutentha kwanyengo nthawi zambiri zimakhala zaka 20. Mukamayaka, pvc imatulutsa utsi wakuda kwambiri komanso mpweya woopsa, pomwe xlpe ntchentche satulutsa mafuta owopsa. Kupambana kwa zingwe zolumikizidwa ndi mtanda kumazindikiridwa ndi kapangidwe kake.
2. Zingwe wamba za PVC (kukumbutsani ndi sheath) zimawotcha msanga ndi kuyamwa mwachangu, kukonza moto. Amataya mphamvu magetsi mkati mwa mphindi 1 mpaka 2. PVC CLUSTIONS imatulutsa utsi wakuda, zomwe zimapangitsa kuti zisapume ndi zovuta zotuluka. Motsimikizika, pvc keranion amatulutsa mpweya woopsa komanso minofu yopanda mphamvu ngati hydrogen. Magetsi awa amapezeka pazida zamagetsi, kunyalanyaza kwambiri magwiridwe antchito ndikutsogolera ku zoopsa zachiwiri zomwe ndizovuta kuti muchepetse.
Ii. Chingwe cha Flamedar
1. Zingwe zokhotakhotakhota ziyenera kuwonetsa mawonekedwe a Flamer ndipo zimaphatikizidwa m'magulu atatu a Flamentant A, B, ndi C Malinga ndi IEC 60332-31 Kalasi yoperekera bwino kwambiri.
Kufananiza kolumikizana ndi ma waya okhazikika komanso opanda moto. Zotsatira zotsatirazi zikuwunikira tanthauzo la kugwiritsa ntchito zingwe zamoto:
a. Mawaya okhazikika amapereka nthawi yopitilira 15 nthawi yothawa poyerekeza ndi mawaya opanda moto.
b. Mawaya okhazikika amawotcha theka lokhalo monga momwe sangalawa okhazikika.
c. Mawaya okhazikika amawonetsa kutentha kwa kutentha kokha kotala imodzi ya maaya opanda moto.
d. Kutulutsa kwa gasi kuphatikizika ndi gawo limodzi mwa magawo atatu a iwo omwe sanyama omwe sakhala amoto.
e. Kugwirira kwa masiteke munthawi yopanda kusiyana kwakukulu pakati pa flamernant komanso zinthu zopanda moto.
2. Chingwe chopanda utsi
Zingwe zokhala zopanda utsi ziyenera kukhala ndi utsi wopanda utsi, komanso mikhalidwe yotsika, komanso mikhalidwe yokhazikika, motsatira izi:
IEC 60754 (mayeso aulere a Halogen) IEC 61034 (mayeso ochepera)
PH Yoyambitsa Mavuto Osachepera
PH≥.3 R≤10us / mm t≥60%
3.. Zingwe zosagwirizana ndi moto
a. Makina osagwirizana ndi moto oyeserera (kutentha kwamoto ndi nthawi) malinga ndi IEC 331-1970 ° ndi 750 ° C kwa maola atatu. Malinga ndi kutanthauza zaposachedwa kwambiri ku IEC 60331 Kukonzekera Kwatsopano kwa IEC Potting, kutentha moto kumachokera ku 750 ° C mpaka 800 ° C Kwa maola atatu.
b. Mawaya osagwirizana ndi moto ndi zingwe zimatha kulembedwa mu chingwe chopanda moto komanso zingwe zosagwirizana ndi moto zokhala ndi moto wokhazikika pazosiyanasiyana zomwe sizikukhulupirira. Zingwe zosagwirizana ndi moto zomwe zimagwiritsa ntchito magwiritsidwe ntchito ogwiritsira ntchito mica ndi zida zotayika monga mawonekedwe akuluakulu, omwe ali ndi zida zambiri. Omwe amakumana mkalasi nthawi zambiri amagwiritsa ntchito matepi apadera a Mika ndi migodi, yamkuwa, yodziwika bwino ngati zingwe zosagwirizana ndi moto.
Zingwe zosagwirizana ndi michere zokhala ndi moto sizingatheke, sizimabala utsi, ndizosagonjetsedwa, zosagwirizana, zosagwirizana, komanso pewani utsi wamadzi. Amadziwika kuti ndi chingwe chamoto, kuwonetsa magwiridwe antchito apamwamba kwambiri pakati pa mitundu yosagwirizana ndi moto. Komabe, njira zawo zopanga ndizovuta, mtengo wake ndi wokwera, kutalika kwawo kwapanga kuli kochepa, ndipo pakadali pano, zotupa zawo zimangochitika zokha. Kukhazikika kosakhazikika ndi zolumikizira zapakati ndizofunikira, kukhazikitsa ndikupanga kumanga kovuta.
