Uea UL3311: Ka Mea Hoʻohui Nui Ma hope o ka 'Iron Man' - Blog

I ka honua ʻoihana hou, ʻaʻole nui ka poʻe koa i hōʻike i ko lākou mau maka. ʻAʻole lākou ʻo nā kaʻa ʻālohilohi a i ʻole nā pihi uwē, akā ʻo nā uea leo e lawe i ka ikehu. I kēia lā: ʻo ka uea UL3311, he "Iron Man" maʻalahi akā ikaika loa. Paʻa paʻa ka pōhaku i ke kiʻekiʻe o ka wela, ka haʻalulu a me ka ʻakika a hiki ke ʻike ʻia i nā mea āpau mai nā forklifts uila a i nā hale hana wili a me nā ʻōnaehana mālama ikehu hou. Mai poina i kēia uea, ʻo ia ka meʻe kaulana ʻole e hāʻawi i ka palekana a me ka pono!

ʻO UL3311 kahi kaila i hoʻomohala ʻia e Underwriters Laboratories (UL) no nā mea uila uila (AWM), e like me nā kūlana UL 758 a me nā kikoʻī CSA C22.2. He 600V kona kaha, ka helu wela kumu o 90 degere (a hiki i ka 105 degere ke hoʻohana pū ʻia me UL3279), a hoʻohana i ka hoʻolalelale kiʻekiʻe - thermosetting EPDM (ethylene propylene diene monomer rubber rubber).

ʻOi aku ka maikaʻi o ka hoʻokaʻawale ʻana o EPDM ma mua o ka PVC maʻamau: ʻo ia ka ʻaila -kūpaʻa, ʻakika-kūʻokoʻa, pale-alkali-kūʻokoʻa, ʻaʻahu -kū kūʻē, a kūpaʻa pū i nā haʻani a me ka ozone. ʻO ka hapa nui o nā mea hoʻokele ka papa K kiʻekiʻe - hiki ke hoʻopaʻa ʻia i ke keleawe ʻulaʻula a i ʻole ke keleawe -pani ʻia, me ka nui o nā kaula (haneri a mau kaukani paha i nā ana nui), hiki ke maʻalahi ka uwea e like me "noodles," e hoʻomaʻamaʻa i ka hoʻokomo ʻana ma nā wahi paʻa a i ʻole nā kūlou pinepine.

Hoʻohālikelike ʻia me nā uea uila maʻamau, ʻo UL3311 kahi hōʻano hou:

UL3311	UL1007	UL1015
600V	300V	600V
90-105 degere	80 degere	105 degere
Hoʻolaha ʻia ʻo EPDM i nā uwila kūloko kiʻekiʻe, -palena i ke ahi a he nui nā mana he halogen-ʻole, e hoʻokuʻu ana i nā kinoea ʻino i ka wā o ke ahi.	PVC lahilahi, kūpono i nā noi ha'aha'a-a me ka māmā-haawe.	ʻOi aku ka mānoanoa o PVC, akā ʻaʻole maikaʻi kona kūpaʻa kūlohelohe e like me EPDM.

Ua hala i ka ho'āʻo hōʻoia UL ikaika a mālama i ka ikaika dielectric maikaʻi loa a me nā waiwai mechanical ma lalo o nā kūlana koʻikoʻi. ʻO ia ke kumu i lilo ai i "evergreen" i ka ʻoihana.

kahua lako wiliwili

I loko o nā hale hana hoʻoheheʻe kahi e lele ai nā kukui, aia nā ʻaila hinu ma nā wahi a pau, a ua loli nui ka wela, ʻo ka UL3311 uea, i hoʻohana ʻia ma ke ʻano he alakaʻi mīkini kuʻi, hiki ke kū i ka ʻenekini mechanical a me ke koʻikoʻi wela, e hōʻoiaʻiʻo ana i ka hoʻouna ʻana i kēia manawa a me ka pale ʻana i nā pōkole pōʻino. ʻOiai ka hū nui ʻana o nā welders, pale mālie kēia uea iā lākou mai nā mea.

Nā alakaʻi kaʻa a me nā uwea kūloko o nā mea uila

Mai nā kaʻa ʻenehana a hiki i nā lako uila UPS kūʻai ʻole a hiki i nā ʻāpana o loko o nā mea hana hale, hāʻawi ʻo UL3311 i nā pilina palekana a hilinaʻi. Hoʻonui kona ʻaloʻalo i ka pono o ka laina hui a kūʻē i ka ʻelemakule a me ka haki ʻana i ka hoʻohana lōʻihi-

Ke au ikehu hou

Aia ma nā wahi a pau: nā mea hoʻohuli o ka lā, nā lako makani makani, UPS kikowaena data, a me nā ʻōnaehana mālama ikehu nui -nui. Ke hoʻopili ʻia nā pūʻulu pākahi he nui, hōʻike ia i ke kūpaʻa ma lalo o ka haʻalulu a me ka loli ʻana o ka mahana, e lilo ia i koho koho no nā OEM he nui. Hoʻopili hou ka mana zero-halogen me nā ʻano hana ʻōmaʻomaʻo, e kōkua ana i nā pahu hopu kalapona.

Nā forklifts uila i loko o ka hale kūʻai

E noʻonoʻo ʻoe i kahi forklift uila e hoʻokele ana i kahi hale kūʻai, kahi e koi aku ai nā pūʻolo pākahiko hilinaʻi kiʻekiʻe-hoʻouna i kēia manawa-ka UL3311 uwea interconnect pākahiko ke koho kūpono loa. ʻO nā anana nui (e like me 4 AWG a i ʻole ka nui) e lawelawe maʻalahi i nā haneli amperes, kūpono ke kūpaʻa ʻakika no ke alakaʻi -acid a i ʻole ka lithium battery environment, a na ka Class K flexible conductor e hiki ai i nā mea hoʻokomo ke hoʻohuli maʻalahi i ke kaulahao.

ʻO ka mea hoihoi, hoʻohana pinepine ʻia ʻo UL3311 me UL3279. ʻO ka mea mua e pili ana i ka hilinaʻi 90 degere, ʻoiai hiki i ka hope ke hiki i 105 degere. Hoʻopili ʻia, uhi lākou i nā hiʻohiʻona kiʻekiʻe a pau -koi loko. ʻAʻole kūpono ia no ke kanu pololei ʻana ma waho a i ʻole nā noi uila -kiʻekiʻe kiʻekiʻe, akā, ʻaʻole hiki ke hoʻohālikelike ʻia ma ke ʻano o ka -mea hoʻonaninani kiʻekiʻe.

E nānā pono kākou i nā "superpowers" o UL3311:

Mea hoʻokele: Ke keleawe -maʻalahi kiʻekiʻe, AWG mai nā uwea hōʻailona maikaʻi a hiki i 1000 kcmil kiʻekiʻe- uwea mana, hiki ke hoʻololi i nā koi like ʻole. Hoʻemi ka hoʻolālā helu strand kiʻekiʻe i ka hopena o ka ʻili a hoʻomaikaʻi i ka hana.
Insulation: Mea EPDM, ʻoi aku ka mānoanoa e like me nā kikoʻī (e laʻa, ma kahi o 0.095 iniha no nā ana nui), hāʻawi i ka pale mīkini maikaʻi loa, kaʻawale uila, a me ka maʻalahi. Loaʻa i kahi kaulike kūpono ma waena o ke kumukūʻai a me ka hana, ʻoi aku ka maikaʻi ma mua o ka silicone rubber a i ʻole Teflon.
ʻO nā hiʻohiʻona o ka hana koʻikoʻi: Ke kūpaʻa abrasion maikaʻi loa, ka maʻalahi, ka pale kemika, a me ka ikaika dielectric kiʻekiʻe. ʻO ka palena wela liʻiliʻi -50 degere, ʻaʻole e ʻoʻoleʻa ʻoiai ma nā wahi anuanu.

Manaʻo Manaʻo Hoʻokomo: E nānā i ka pākaukau hiki ke lawe i kēia manawa i ke koho ʻana i kahi kumu hoʻohālike (e noʻonoʻo ana i ka emi ʻana ma muli o ka wela o ka ambient) a e hoʻohana i nā hopena crimp kūpono. E mālama i kahi mamao mai ka lā a me nā mea ʻoi, a e nānā mau i ke kūlana insulation. Hoʻohālikelike ʻia me nā uea PVC, ʻaʻole hiki ke palupalu i nā wela kiʻekiʻe a ʻoi aku ka lōʻihi o ke ola ʻana ma nā wahi kemika, e lilo ia i uea "lōʻihi{2}}mau loa".

Hāʻawi nā brands e like me Southwire, Cobra Wire, a me Direct Wire i nā huahana oʻo, mai nā uwea uila AWG maikaʻi a hiki i nā uwea pākaukau mānoanoa. Ke kūʻai ʻana, e ʻimi i ka māka UL a nānā i ka helu faila E-o ka mea hoʻolako e hōʻoia i ka hoʻokō ʻana i nā kikoʻī o ka papahana.

Me ka nalu electrification (EVs, energy storage, robotics, 5G base stations), e pahū ke koi no kēia mau uea AWM hana kiʻekiʻe. I ka wā e hiki mai ana, e ʻālohilohi paha lākou i nā mea akamai aʻe, e lilo i "nā ipu koko" e pili ana i ka ikehu ʻōmaʻomaʻo.

ʻO kaʻoiaʻiʻo, pono e hoʻohana pono ʻia nā uea maikaʻi loa: e pale i ka overloading a hana i ka mālama mau e hoʻonui i ko lākou waiwai. ʻO ka palekana ka mea nui loa!

ʻAʻole paha he hiʻohiʻona ʻōlinolino o UL3311, akā ua lanakila kāna hana hilinaʻi ma luna o nā ʻenekinia. ʻAʻole ʻo ia i nā wela kiʻekiʻe, hoʻomanawanui i nā haʻalulu, a hāʻawi i ke kākoʻo koʻikoʻi i nā manawa koʻikoʻi-he ʻano maoli o ka ʻuhane ʻoihana. I ka manawa aʻe e ʻike ʻoe i ka holo mālie ʻana o nā mea uila a i ʻole ka mīkini wiliwili e hana mau ana, e hoʻomanaʻo i ka moʻolelo ma hope o kēia uwea.
