ʻO ke kaula crosslinked he pōkole no ke kaula insulated polyethylene crosslinked (XL-PE). He kūpono nā kaula crosslinked no nā laina hoʻoili a me ka hāʻawi ʻana me ka uila mana alapine ac a hiki i ka 500KV. I kēia manawa, ua hoʻopaʻa ʻia ka hapa nui o nā kaula uila kiʻekiʻe e ka polyethylene crosslinked.
ʻO nā kaula i hoʻopili ʻia e pili pinepine i nā kaula nona ka insulation i hana ʻia me nā mea i hoʻopili ʻia. ʻO ka mea i hoʻohana pinepine ʻia ʻo ka polyethylene i hoʻopili ʻia (XLPE). ʻO ke kaʻina hana crosslinking ka hana ʻana i ka ʻano molekala linear o ka polyethylene (PE) ma o kahi ala hana kikoʻī e hana i ke ʻano o ka ʻano laina reticulated polyethylene crosslinking. ʻO ka hopena, ua hoʻokiʻekiʻe ʻia ka mahana hana i ʻae ʻia no ka manawa lōʻihi mai 70 ℃ a i 90 ℃ (a i ʻole kiʻekiʻe), a ua hoʻokiʻekiʻe ʻia ka mahana i ʻae ʻia no ka pōkole mai 140 ℃ a i 250 ℃ (a i ʻole kiʻekiʻe), kahi e hoʻomaikaʻi nui ai i ka hana maoli ma lalo o ke kumu o ka mālama ʻana i kāna hana uila maikaʻi loa.
Nui nā pono no XLPE. Hāʻawi ʻo Wenchang i nā ʻano XLPE he nui no kāu koho.
E like me UL3265, UL3266, UL3167, UL3173, UL3182, UL3194, UL3195, UL3196, UL3199, UL3236 a pēlā aku.
(1) Nā waiwai mechanical a me ke kino maikaʻi loa, kūpaʻa maikaʻi i ka haki ʻana o ke kaiapuni, kūpaʻa ʻaʻahu maikaʻi loa, ʻoi aku ka nui o ke kūpaʻa ʻana o ka PVC a me PE i ke kaumaha mechanical i hoʻopaʻa ʻia.
(2) Kūpaʻa i nā mea hoʻoheheʻe kemika like ʻole, paʻa i nā ʻano media corrosive like ʻole a puni.
(3) ʻOi aku ka liʻiliʻi o ke anawaena o waho o ka uea polyolefin i hoʻopili ʻia i ka irradiated ma mua o ke uea polyvinyl chloride āpau me ka ʻāpana kikoʻī like, hiki ke hōʻemi i ke anawaena paipu i hoʻohana ʻia i ke kūkulu ʻana i ke kaula paipu, a i ʻole e ʻaʻahu i nā uea hou aʻe ma lalo o ke kūlana anawaena paipu like, a pēlā e hōʻemi ai i ke kumukūʻai hoʻonohonoho kūkulu.
(4) ʻOi aku ka māmā o ka huahana uea insulated polyolefin irradiation crosslinked ma mua o ka huahana uea insulated PVC, ʻoi aku ka maʻalahi no ke kau ʻana a me ka halihali ʻana, e hoʻemi ana i ka ikaika o ka hana a me ke kumukūʻai halihali.
(5) Hiki i ka mahana kiʻekiʻe loa o ka uea insulated crosslinked irradiated ke hiki i 125 ℃ i ka wā hana lōʻihi, a ʻoi aku ka nui o ka hiki ke lawe ma mua o ka uea insulated PVC.
(6) ʻAʻole ia e hoʻokuʻu i nā kinoea ʻino a i ʻole nā kinoea ʻawahia i ka wā e puhi ai, a ʻaʻole ia e hōʻino lua. He ʻano huahana palekana kaiapuni hou ia e kūlike me nā koi palekana ahi o kēia wā.
(7) Hana uila maikaʻi, ʻoi aku ke kiʻekiʻe o ke kūpaʻa insulation ma mua o ke kaula PVC, a he liʻiliʻi loa ka tangent angle loss medium, ʻaʻole ia e loli me ka loli o ka mahana.
