Huahana Huahana

Hōʻike huahana

Loaʻa i ka overhead insulated cable nā hiʻohiʻona o ka lawe mana nui a me ka ikaika mechanical ikaika.Ke hoʻohālikelike ʻia me nā uea hū ʻole, loaʻa iā ia nā mea maikaʻi o ka liʻiliʻi o ka waiho ʻana, ka palekana kiʻekiʻe a me ka hilinaʻi, a me ke kūpaʻa maikaʻi ʻana i ka wā kahiko.Hoʻohana maikaʻi ʻia nā racks no nā hana kūkulu mana o ke kūlanakauhale a me ke kua'āina.
He kūpono kēia huahana no nā laina mana o luna a me nā laina hoʻoili a me ka hāʻawi ʻana me ka AC helu ʻia U (Um) 10 (12) KV a ma lalo i nā hale kiʻekiʻe o ke kūlanakauhale, nā wahi hoʻomohala mākaʻikaʻi, nā wahi ulu lāʻau, etc.
Kū ʻo JK no luna
ʻO L ka mea alakaʻi he uea alumini,
ʻO Y no ka polyethylene,
ʻO YJ ka polyethylene i hoʻopili ʻia,
JKLY uwea insulated overhead.

Nā kuhikuhi huahana no ka hoʻohana

(1) He 10 kV ka volta helu o ke kaula.
(2) Max.ʻAe ʻia ka mahana hana lōʻihi o ka conductor:
Xlpe insulation he 90 ℃
Kiʻekiʻe kiʻekiʻe polyethylene insulation 75 ℃
(3) Ke kaapuni pōkole (ʻo ka lōʻihi loa ʻaʻole i ʻoi aku ma mua o 5 kekona), ʻo ka wela kiʻekiʻe o ke kaula:
Xlpe insulation he 250 ℃
ʻO ka insulation polyethylene kiʻekiʻe he 150 ℃.

Nā palena ʻenehana huahana

Nā hiʻohiʻona hoʻolālā huahana

1. Hoʻohālikelike ʻia me ke kila kila alumini stranded uea, ʻo ka insulated overhead cable nā mea maikaʻi o ka mamao hoʻokomo liʻiliʻi ma waena o nā kaula, hoʻemi ʻia ka nui, a me ke kumu palekana kiʻekiʻe.
2. Hoʻohana nui ʻia nā kaula i hoʻopaʻa ʻia ma luna o ke poʻo i ka hoʻololi ʻana i nā mana mana ma nā kūlanakauhale a me nā wahi nahele.He mea maʻalahi ka huahana, palekana i ka hoʻohana ʻana, a loaʻa iā ia nā waiwai mechanical, kino a me nā uila.Kūʻē maikaʻi loa i ka nānā ʻana, ka hoʻokuʻu ʻana o ka ʻili a me ke kū ʻana o ka lewa.I ka manawa like, i ka wā e hoʻohana ʻia ai ke kelepona ma luna no ka hoʻouna ʻana i ka mana lōʻihi ma nā wahi e pili ana i ke kaona, he haʻahaʻa loa ke kumukūʻai inductance, a he liʻiliʻi ka hāʻule o ka laina.Mai hoʻonui i nā hana hoʻoikaika, i loaʻa nā pono waiwai kiʻekiʻe.
