EPDM (Ethylene Propylene Diene Monomer) waya dzakaiswa insulated dzinoshandiswa zvakanyanya mumaindasitiri, emotokari, simba uye maindasitiri emidziyo yemumba nekuda kwekunyanya kupisa kupisa, kuramba kwemamiriro ekunze uye zvinhu zvemagetsi. EPDM imhando yezvakagadzirwa rabha zvinhu zvine saturated main cheni chimiro, saka ine kumira zvakanaka kune oxidation, ozone uye ultraviolet mwaranzi, uye inogona kushanda yakagadzikana munzvimbo yakaoma kwenguva yakareba. Iye zvino isu tinoongorora maitiro uye parameters yeEPDM wayas, kunyanya mhando mbiri dzakakurumbira, UL3311 uye UL3279 uye maitiro avo chaiwo uye mapoinzi akakosha ekushandisa. Fekitori yedu inoitika kugadzira ese ari maviri emhando idzi. Kana uchida kudzidza zvakawanda kana kuzvitenga, ndapota inzwa wakasununguka kutibata nesu.
Yakasarudzika mabhenefiti eEPDM zvinhu
EPDM irabha yekugadzira copolymerized kubva ethylene, propylene, uye shoma shoma ye diene monomers. Yayo molecular chimiro ine yakaderera kaviri bond yemukati, nokudaro ichiratidza yakanakisa kugadzikana kwemakemikari uye kuchinjika kwezvakatipoteredza. Kana ichienzaniswa nerabha rechisikigo kana mamwe marabha asina unsaturated, EPDM inoratidza kushanda kwepamusoro mukupisa kupisa, kushoma-kuramba kudziya, kusaita mwando, UV resistance, uye chemical resistance.

Tsanangudzo Yakadzama yeUL3311 uye UL3279 Model Nhamba
Muzvigadzirwa zvewaya zveEPDM, UL certification iindasitiri-inotungamira mwero unovimbisa kuchengetedzwa kwechigadzirwa uye kusachinja-chinja.UL3311uyeUL3279ndiwo maviri anoshandiswa zvakanyanya bhatiri tambo uye mota lead yakatarwa, kazhinji inosimbiswa pamwechete kana kushandiswa nenzira inowirirana.
UL3311
Zvakanyanya kugadzirirwa flexible single-conductor motor lead uye waya dzemukati dzine tembiricha yakayerwa ye90 degrees . Inoenderana neUL uye CSA zviyero, voltage yakayerwa pa600V. Kuvaka kwakajairika kunosanganisira Kirasi K (30 AWG yakanaka strand) isina kana matani emhangura conductor, bepa insulation layer, uye EPDM yekunze sheath. Insulation ukobvu hunosiyana zvichienderana nesaizi yekondakita (kazhinji 0.060-0.080 inches yemakondukita ari pamusoro pe8 AWG), uye inogaro chinjika, isinga piriviri, uye iri nyore kubvisa. Tembiricha inosiyana -50 madhigirii kusvika +90 madhigirii, akakodzera masisitimu ebhatiri, tambo dzemasolder, UPS, uye waya dzemukati mumidziyo yemumba.
UL3279
Inowanzo kupetwa neUL3311, ichipa yakakwira rated tembiricha sarudzo ye105 degree. Zvakare 600V, EPDM insulated, inokodzera maapplication anoda kuenderera mberi tembiricha yakakwira zvishoma, yakadai semamotor lead kana magetsi anokochekera munzvimbo dzakakwirira-. Iwo maviri mamodheru akafanana zvakanyanya, uye vagadziri vazhinji vanopa zvigadzirwa zvinosangana panguva imwe chete UL3311/UL3279, zvichipa kuchinjika.

Mamiriro ekushandisa akajairika
EPDM waya inopenya mumaindasitiri akawanda nekuda kwekusiyana kwayo:
Inoshandiswa kubatanidza mukati memotokari yemagetsi (EV) mabhatiri packs, -mahanesi emagetsi, uye masisitimu ekuchajisa. Kuramba kwayo asidhi, kuzunguzika kwayo, uye tembiricha yakakura inoita kuti ivimbike kwenguva refu-.
Inoshandiswa senge mota inotungamira, transformers, coils, uye mukati wiring mumidziyo. UL3311/3279 modhi dzakanyanya kukodzera mota dzepamusoro-dzinopisa kana midziyo inoda kugara ichibhenda.
Welding tambo, solar inverters, mhepo midziyo yemagetsi, uye UPS masisitimu. EPDM yemamiriro ekunze kuramba inoita kuti ive yakakodzera kune yekunze photovoltaic kana mhepo yekuisa magetsi.
Yakanyanya kuchinjika kufambiswa kwemagetsi mumakungwa, njanji, uye ekuvaka michina maindasitiri
Mumaapplication chaiwo{{0}epasi rose, vagadziri vakawanda vanopa zvigadzirwa zvinobvira pa8 AWG kusvika 4/0 kana zvikure, zvinotsigira kureba nemavara (kazhinji tsvuku/dema), sezvazvinoita kufekitari yedu.
Maitiro ekusarudza iyo chaiyo modhi uye yekuisa precaution

Panguva yekuisa, teerera kusarudzwa kwechishandiso chekubvisa cheEPDM insulation kudzivirira kukuvadza conductor. Kuchengetedza kunofanira kuchengetedzwa kubva kuchiedza uye unyoro, pasinei nekudzivirira kwayo kwakasimba kwemamiriro ekunze. Yakakodzera crimp terminals inokurudzirwa yekubatanidza, uye kuongororwa kwemagetsi kunofanirwa kuitwa.
Matarisiro eMusika uye Mafambiro Ekusimudzira eEPDM Wire
Sezvo nyika inoshandura kuchenesa simba uye magetsi, kudiwa kweEPDM wayainoramba ichikura. Kudiwa kwemidziyo yekudzivirira inovimbika mumotokari itsva dzesimba, 5G base stations, data centers, uye smart grids kuri kufambisa kugadzirwa kwezero-halogen, yakaderera-utsi, uye yakakwirira voltage{4}}level zvigadzirwa. Mune ramangwana, EPDM composite zvinhu zvinogona kuwedzera kunatsiridza dielectric properties uye simba remuchina kuti rizadzise zvinodiwa zvepamusoro-maapplications ekupedzisira senge.HVDC (yakakwirira voltage yakananga ikozvino) cable accessories.
Pakusarudza-mhando yepamusoroEPDM wayamutengesi, zvinokurudzirwa kuisa pamberi makambani ane yakazara UL certification kuti ive nechokwadi chekuenderana uye kutsigirwa kwehunyanzvi. Semuenzaniso, fekitori yedu inyanzvi.
Mhedziso
EPDM waya, kunyanya mamodheru anoenderana neUL3311 uye UL3279 zviyero, ndiyo mhinduro yakasarudzika yekubatanidza magetsi eindasitiri nekuda kwekuita kwayo kwakaringana, zvitupa zvakavimbika zvekuchengetedza, uye kushanda kwakafara. Inopa kusimba kwemagetsi ekudzivirira uye kudzivirira kwemuchina, kungave munzvimbo dzakaomarara dzekunze kana mukati chaimo michina. Mukutsvaga kwemazuva ano kwekushanda, kuchengeteka, uye kusimudzira kwakasimba, kunzwisisa uye kushandisa nemazvoEPDM wayaichawedzera vimbiso yakasimba kumapurojekiti ako.
