Hoʻohana nui ʻia ke kaula mana polyethylene i hoʻopili ʻia i loko o ka ʻōnaehana mana ma muli o kona mau waiwai wela a me ka mechanical maikaʻi, nā waiwai uila maikaʻi loa a me ke kūpaʻa i ka palaho kemika. Loaʻa iā ia nā pono o ke ʻano maʻalahi, ke kaumaha māmā, ʻaʻole i kaupalena ʻia ke kau ʻana e ka hāʻule ʻana, a hoʻohana nui ʻia i nā pūnaewele mana kūlanakauhale, nā mines, nā mea kanu kemika a me nā hiʻohiʻona ʻē aʻe. Hoʻohana ka insulation o ke kaulapolyethylene i hoʻopili ʻia, kahi i hoʻololi ʻia me ke kemika mai ka polyethylene molekala linear i loko o kahi ʻano pūnaewele ʻekolu-dimensional, no laila e hoʻomaikaʻi nui ana i nā waiwai mechanical o ka polyethylene me ka mālama ʻana i kona mau waiwai uila maikaʻi loa. Hōʻike kēia ma lalo nei i nā ʻokoʻa a me nā pono ma waena o nā kaula polyethylene insulated crosslinked a me nā kaula insulated maʻamau mai nā ʻano he nui.
1. Nā ʻokoʻa o nā mea
(1) Ke kū'ē ʻana i ka mahana
ʻO ka helu mahana o nā kaula insulated maʻamau he 70°C, ʻoiai ʻo ka helu mahana o nā kaula polyethylene insulated cross-linked hiki ke piʻi i 90°C a ʻoi aku paha, e hoʻomaikaʻi nui ana i ke kūpaʻa wela o ke kaula, e kūpono ai no nā wahi hana ʻoi aku ka paʻakikī.
(2) Ka hiki ke hāpai
Ma lalo o ka ʻāpana ʻāpana like o ke alakaʻi, ʻoi aku ka kiʻekiʻe o ka mana lawe o kēia manawa o ke kaula insulated XLPE ma mua o ke kaula insulated maʻamau, hiki ke hoʻokō i nā koi o kēia manawa me ka ʻōnaehana hoʻolako mana.
(3) Ka laulā o ka noi
E hoʻokuʻu nā kaula insulated maʻamau i ka uahi HCl ʻawahia ke puhi ʻia, a ʻaʻole hiki ke hoʻohana ʻia i nā hiʻohiʻona e pono ai ka pale ʻana i ke ahi kaiapuni a me ka ʻawahia haʻahaʻa. ʻAʻole i loko o ke kaula insulated polyethylene cross-linked ka halogen, ʻoi aku ka launa pū me ke kaiapuni, kūpono no nā pūnaewele hoʻolaha, nā hoʻonohonoho ʻoihana a me nā hiʻohiʻona ʻē aʻe e pono ai ka uila nui, ʻoiai ʻo AC 50Hz, ka uila i helu ʻia he 6kV ~ 35kV mau laina hoʻoili a me ka hoʻolaha paʻa.
(4) Paʻa kemika
Loaʻa i ka polyethylene crosslinked ke kūpaʻa kemika maikaʻi a hiki ke mālama i ka hana maikaʻi loa i ke kaiapuni o nā waikawa, alkalis a me nā kemika ʻē aʻe, kahi e kūpono ai no ka hoʻohana ʻana i nā hiʻohiʻona kūikawā e like me nā mea kanu kemika a me nā kaiapuni moana.
2. Nā pono o ke kaula polyethylene insulated cross-linked
(1) Ke kū'ē wela
Hoʻololi ʻia ka polyethylene crosslinked e nā ʻano kemika a kino paha e hoʻololi i ke ʻano molekala linear i loko o kahi ʻano pūnaewele ʻekolu-dimensional, kahi e hoʻomaikaʻi nui ai i ke kūpaʻa wela o ka mea. Ke hoʻohālikelike ʻia me ka polyethylene maʻamau a me ka insulation polyvinyl chloride, ʻoi aku ka paʻa o nā kaula polyethylene crosslinked i nā wahi mahana kiʻekiʻe.
(2) ʻOi aku ka mahana hana
Hiki i ka mahana hana i helu ʻia o ke alakaʻi ke piʻi i 90 ° C, ʻoi aku ke kiʻekiʻe ma mua o nā kaula PVC kuʻuna a i ʻole polyethylene insulated, no laila e hoʻomaikaʻi nui ana i ka hiki ke lawe i kēia manawa o ke kaula a me ka palekana hana lōʻihi.
(3) Nā waiwai mīkini kiʻekiʻe loa
ʻO ke kaula polyethylene insulated crosslinked he mau waiwai thermo-mechanical maikaʻi nō ia i ke kiʻekiʻe o ka mahana, ʻoi aku ka maikaʻi o ka hana ʻana i ka wela, a hiki ke mālama i ka paʻa mechanical i kahi ʻano wela kiʻekiʻe no ka manawa lōʻihi.
(4) Māmā ke kaumaha, hoʻonohonoho kūpono
ʻOi aku ka māmā o ke kaumaha o ke kaula polyethylene insulated cross-linked ma mua o nā kaula maʻamau, a ʻaʻole i kaupalena ʻia ke kau ʻana e ka hāʻule ʻana. He kūpono loa ia no nā wahi kūkulu paʻakikī a me nā hiʻohiʻona hoʻokomo kaula nui.
(5) Hana maikaʻi aʻe no ke kaiapuni:
ʻAʻohe halogen i loko o ke kaula polyethylene insulated cross-linked, ʻaʻole hoʻokuʻu i nā kinoea ʻawahia i ka wā e puhi ai, ʻaʻohe hopena iki i ke kaiapuni, a kūpono loa ia no nā wahi me nā koi koʻikoʻi no ka palekana o ke kaiapuni.
3. Nā pono i ke kau ʻana a me ka mālama ʻana
(1) ʻOi aku ka lōʻihi o ke kūpaʻa
ʻOi aku ka kiʻekiʻe o ka hana anti-kahiko o ke kaula polyethylene insulated crosslinked, kūpono no ke kanu ʻana i ka wā lōʻihi a i ʻole ka ʻike ʻana i ke kaiapuni waho, e hōʻemi ana i ke alapine o ka hoʻololi ʻana i ke kaula.
(2) Hilinaʻi ikaika o ka pale ʻana
ʻO nā waiwai insulation maikaʻi loa o ka polyethylene crosslinked, me ke kūpaʻa voltage kiʻekiʻe a me ka ikaika breakdown, e hōʻemi ana i ka pilikia o ka hāʻule ʻana o ka insulation i nā noi voltage kiʻekiʻe.
(3) Nā kumukūʻai mālama haʻahaʻa
Ma muli o ke kūpaʻa ʻana i ka pala a me ke kūpaʻa ʻana i ka wā ʻelemakule o nā kaula polyethylene insulated crosslinked, ʻoi aku ka lōʻihi o ko lākou ola lawelawe, e hōʻemi ana i nā kumukūʻai mālama a me nā hoʻololi i kēlā me kēia lā.
4. Nā pono o ke kākoʻo loea hou
I nā makahiki i hala iho nei, me ka hoʻomaikaʻi ʻana o ka ʻenehana mea polyethylene crosslinked, ua hoʻomaikaʻi hou ʻia kāna hana insulation a me nā waiwai kino, e like me:
Hoʻonui ʻia ka mea pale lapalapa, hiki ke hoʻokō i nā wahi kūikawā (e like me ke kaʻaahi, ke kahua mana) nā koi ahi;
Hoʻomaikaʻi ʻia ke kūpaʻa anu, paʻa mau i ke kaiapuni anu loa;
Ma o ke kaʻina hana crosslinking hou, ʻoi aku ka maikaʻi o ke kaʻina hana hana kaula a ʻoi aku ka launa pū me ke kaiapuni.
Me kāna hana maikaʻi loa, noho nā kaula polyethylene insulated cross-linked i kahi kūlana koʻikoʻi ma ke kahua o ka hoʻoili mana a me ka hāʻawi ʻana, e hāʻawi ana i kahi koho palekana, hilinaʻi a pili i ke kaiapuni no nā pūnaewele mana kūlanakauhale hou a me ka hoʻomohala ʻoihana.
