ʻO ke koho ʻana i ka uea a me ke kaula i ka hana ʻana i nā mea uila a me nā mea uila e pili pono ana i ka palekana o ka huahana, ka hilinaʻi a me ka hoʻokō hoʻoponopono. ʻO UL1672 kahi maʻamau mai nā Underwriters Laboratories (UL) no ka mea hoʻohana uila (AWM) a he mea koʻikoʻi ia i nā noi uea kūloko. Hāʻawi kēia ʻatikala i kahi kikoʻī kikoʻī i ka uea UL1672 e pili ana i nā ʻenehana ʻenehana maoli a me nā hana ʻoihana, me nā palena, ka hoʻolālā, nā pono hana a me nā hiʻohiʻona noiʻi, a hoʻohālikelike ʻia me nā kūlana UL ʻē aʻe, i hiki ai i nā mea ʻenekinia, nā limahana kūʻai a me nā mea makemake uila ke hoʻomaopopo maikaʻi i kēia ʻano uea i hoʻohana nui ʻia.
Nānā o ka UL1672 Standard
Loaʻa nā kikoʻī ʻenehana nui:
-
Helu uila: 300V AC
-
Kaulana wela: 105 degere
-
Conductor: Paʻa paʻa a i ʻole ke keleawe keleawe i hoʻopaʻa ʻia (loaʻa ke koho tinned)
-
Hoʻopili: PVC (polyvinyl chloride)
-
Kāleka/Uhi: PVC i hoʻokuʻu ʻia a i ʻole XLPVC (cross{0}}linked PVC)
-
Hoʻopaʻa ʻia ka lapalapa ahi: Holo i ka UL VW-1 a me CSA FT1 i nā hoʻāʻo ʻana o ka lapalapa ʻana
Hoʻohālikelike ʻia me nā uea lou -up (e like me UL1007), hōʻike ʻia ka UL1672 i ka hana ʻelua-papa (ka hoʻopuʻi me ka uhi). Hoʻonui nui kēia i ka pale ʻana i ka abrasion, ka ikaika mechanical, a me ka lōʻihi o ke kaiapuni, e kūpono loa ia no nā noi uila kūloko e pono ai ka pale hou.
Hoʻolālā Huahana a me nā Pono Mea
Aia kekahi uea UL1672 maʻamau i nā ʻāpana penei:
1. Conductor: Hana ʻia me ke keleawe -maʻemaʻe kiʻekiʻe, e hāʻawi ana i ka hoʻoili uila maikaʻi loa. Hāʻawi nā mea alakaʻi i hoʻopaʻa ʻia (e laʻa, 7/0.193mm no 24AWG) i ʻoi aku ka maʻalahi, e kūpono ai lākou no nā noi e pili ana i ka piko pinepine. Hāʻawi nā ʻano tinned i hoʻonui i ka pale ʻana i ka oxidation a me ka solderability.
2.Insulation: Uniformly extruded PVC mea e hōʻoiaʻiʻo like mānoanoa, hoʻomaʻamaʻa maʻalahi wehe a me ka terminal hana. Hāʻawi ʻo PVC i nā waiwai hoʻokaʻawale uila maikaʻi a me ka maikaʻi-kuai.
3.Outer Covering: ʻO kahi papa extruded hou o PVC a i ʻole XLPVC hāʻawi i ka pale mechanical. Hoʻokaʻawale kēia uhi i ka UL1672 mai nā uea hoʻokahi -insulated; ʻo kona mānoanoa maʻamau e hōʻoia i ka pale ʻana i ka abrasion a me ke kaomi.
Nā waiwai waiwai maikaʻi loa:
1.Environmental kū'ē: Kū'ē i ka wai, kaʻaila, nāʻakika, nā mea hoʻohenehene, a me ka uluʻana o ka fungal; kūpono no nā wahi ʻoihana.
2.Flame retardancy: Haʻahaʻa uahi a haʻahaʻa toxicity; hoʻokō i nā koi palekana ahi.
3.Flexibility a me ka processability: Uniform mānoanoa hoʻomaʻamaʻa automated uea wehe a me ka soldering; kū'ē i ka hoʻoheheʻe ʻana i ka hoʻopili ʻana me kahi hao hao (ʻoi aku ka mana XLPVC).
4.Color coding: Kākoʻo i nā code kala like ʻole (eg, ʻulaʻula, ʻeleʻele, uliuli, keʻokeʻo) no ka ʻike kaapuni maʻalahi.
No ka laʻana, ʻo ka pepa kikoʻī i hāʻawi ʻia e kā mākou hale hana e hōʻike ana i ka 18 AWG stranded conductor version e hōʻike ana i kahi anawaena kūpono o waho, me ke kaupaona a me nā waiwai kūʻē e kūpono ana i nā kūlana, a me ke kūpaʻa conductor kiʻekiʻe ma 20 degere i mālama ʻia i loko o kahi pae kūpono.
ʻIkepili o nā pono hana
1. Ka palekana a me ka hoʻokō ʻana: ʻO ka hōʻoia ʻana o ka UL e hōʻike ana ua loaʻa ka huahana i nā hoʻokolohua koʻikoʻi o ke keʻena hoʻokolohua, e like me ke kūpaʻa ʻana o ka volta, ka ʻelemakule wela, ka retardancy ahi, a me nā hoʻāʻo koʻikoʻi mechanical. Ma ka mākeke ʻAmelika ʻAmelika, lawelawe kēia ma ke ʻano he "passport" no ke komo ʻana i nā ʻāpana e like me nā mea hana hale a me nā mea lapaʻau. Hiki i nā uea helu ʻole{3}}UL ke kū i ka hemahema o ka hōʻoia ʻana a i ʻole he pilikia palekana.
2. ʻO ka Mahana a me ka Voltage kūpono: ʻO ka helu 105 degere ʻoi aku ma mua o ka nui o nā uea PVC maʻamau (80 degere), e ʻae ana i ka hana paʻa i nā mahana ambient kiʻekiʻe. He kūpono ka helu 300V no nā kaapuni kūloko haʻahaʻa haʻahaʻa.
3. Paʻa Mechanical: Hāʻawi ka hana ʻelua -papa ʻelua i ke kūpaʻa abrasion maikaʻi loa, no laila kūpono ia no ke alahele ʻana a puni nā kihi ʻoi a i ʻole i loko o nā mea haʻalulu. Hoʻohālikelike ʻia me ka uea hoʻokahi-insulated, hoʻemi ia i ka pōʻino o ka insulation.
4. Pili Kaiapuni a me ka Hoʻohālikelike: Nui nā mea hana e hāʻawi i ke alakaʻi -free, RoHS- mana e kākoʻo pū ana i ka CSA AWM palapala, e hiki ai i ka palapala hōʻoia ʻelua no ka mākeke ʻAmelika ʻĀkau.
5. Uku -Pono: ʻOiai e hāʻawi ana i ka hana hilinaʻi, ua kūʻai haʻahaʻa ke kumu kūʻai o PVC-e kumu kūpono no ka hana nui ʻana.
Nā hiʻohiʻona noi nui
Hoʻohana nui ʻia ka UL1672 i:
-
ʻO nā uwea kūloko no nā mea hana hale: ʻO nā ea, nā umu microwave, nā kuke laiki, nā keʻena disinfection, a me nā mea pono hale ʻē aʻe.
-
Nā lako uila: Nā panela hoʻomalu, nā mea kani, nā mea hoʻololi mana, nā ʻaoʻao kamepiula, a me nā lako hana ʻenehana.
-
Nā mea hana lapaʻau a me ka pololei: ʻO nā pilina kūloko no nā mea lapaʻau e koi ana i ka hilinaʻi kiʻekiʻe a me ka pale ahi.
-
Nā mea hoʻohana ʻē aʻe: Robotics, nā hoʻokele elevator, ʻōnaehana kōkua uila uila (ʻole{0}}laina uila), etc.
Ma nā hoʻohana pono, hoʻohana pinepine ʻia ʻo UL1672 ma ke ʻano he uwea lou -up no nā mea mīkini, nā keʻena hoʻomalu, a me nā mea hana. ʻO kona maʻalahi a me ke kūpaʻa kemika e hōʻoia i ka hana maikaʻi loa i nā wahi hoʻonohonoho hale hana. Wahi a nā alakaʻi alakaʻi UL, ua manaʻo nui ʻia kēia ʻano uea AWM no ka wili o ka hale hana ma ke ʻano he mea pili i loko no nā mea hana.
Hoʻohālikelike me nā kūlana UL ʻē aʻe
ʻO ka hoʻomaopopo ʻana i kahi e kūpono ai ʻo UL1672 i ke koho kūpono:
UL1007: Ua helu 'ia no 80 degere a me 300V me ka -papa ho'okahi; ʻoi aku ka lahilahi a hoʻohana mau ʻia no ka uwea lou -maʻamau. Hōʻike ka UL1672 i ka hoʻolālā ʻelua-papa e hāʻawi i ka pale ʻoi aku.
UL1015: Ua helu ʻia no 80–105 degere a me 600V; lawelawe 'o ia i na volta ki'eki'e, 'oiai e 'oko'a paha kona mānoanoa, no laila kūpono 'o ia no nā noi uila - ki'eki'e.
UL1061: Loaʻa nā hiʻohiʻona semi-oolea PVC hoʻokaʻawale; kūpono no nā lako hoʻopaʻa leo kikoʻī.
UL1571: Nā hiʻohiʻona ʻoi aku ka lahilahi o ka insulation; kūpono no ka -pololei i kaupalena 'ia.
UL1672hāʻawi i ke koena kūpono o ka mānoanoa, ka pale, a me ke kumukūʻai, no laila, kūpono loa ia-no nā noi e koi ana i ka pale mīkini ʻē aʻe inā ʻaʻole i ʻoi aku ka uila ma mua o 300V.
Nā ʻenehana a me ka wā e hiki mai ana
ʻO ke ʻano o nā mea uila he miniaturization, hoʻohui kiʻekiʻe a me ka hana akamai, kahi e alakaʻi ai i nā koi ʻoi aku ka paʻakikī o nā uea uila. Ua hoʻomau ka UL1672 i ka ulu ʻana ma ke ʻano he maʻamau e hoʻokō i nā kauoha kūlohelohe e like me ka hoʻokō ʻana o RoHS, nā kikoʻī manuahi halogen, a me nā ʻano uahi haʻahaʻa. E hoʻomaikaʻi hou aku i ka hana ma nā hanauna e hiki mai ana nā mea i hoʻopili ʻia a me nā ʻenehana alakaʻi kiʻekiʻe.
ʻO Kina kahi kumu hana nui o nā uea uila ma ke kaulahao lako honua. Nui nā hale hana ma Kina i hoʻokuʻu aku i ka nui o nā huahana e kū ana i nā kūlana UL1672, e hoʻoikaika ana i ka ulu ʻana o ka mea hana hale a me nā ʻoihana uila.
Ka hopena
ʻO ka uea UL1672 ka mea i koho ʻia e nā ʻenekinia he nui ma muli o kāna hana palekana hilinaʻi, nā waiwai mechanical maikaʻi a me ka hoʻohana ākea. ʻAʻole kēia ʻo ka uea "kiʻekiʻe" loa ma laila, akā ʻo ia kekahi o nā mea kūpono a kaulike. Inā hoʻolālā ʻoe i nā kaʻa kaʻapuni home, mālama i nā mea hana ʻenehana, a i ʻole nā mea uila kumu, ʻo ka ʻike ʻana i ka UL1672 e kōkua iā ʻoe e hoʻoholo i ka maikaʻi.
Loaʻa i ka hana hou ka palekana e like me ka laina lalo. ʻO ka uea i hōʻoia ʻia ʻo UL kahi laina pale ikaika no kāu huahana a no ka poʻe hoʻohana i kāu huahana.
