ʻAʻole wale ka maikaʻi o ka uila, nā waiwai mechanical, akā, he kūʻē ikaika nō hoʻi i ka corrosion kemika, ka wela a me ke koʻikoʻi o ke kaiapuni.He maʻalahi kona ʻano.ʻO ka mahana hana lōʻihi he 90ºC. He maʻalahi ia e hoʻohana a hiki ke waiho ʻia me ka ʻole o ka palena ʻole o nā pae like ʻole.
Hoʻopaneʻe i ka laha ʻana o ka lapalapa ma ke kaula i ʻole e hoʻonui ʻia ke ahi.Ma muli o kona kumu kūʻai haʻahaʻa, hoʻohana nui ʻia i nā kaula ahi.Ma lalo o nā kūlana o ke kaula hoʻokahi a i ʻole ka waiho ʻana i ka pūpū, hiki ke hoʻomalu ʻia ka laha ʻana o ke ahi i loko o kahi ʻano i ka wā e ʻā ana ke kaula, no laila hiki ke pale ʻia nā pōʻino nui i hana ʻia e ke ahi, i mea e hoʻomaikaʻi ai i ka pae pale ahi o ka laina kelepona. .

Nā kuhikuhi huahana no ka hoʻohana

A) i ka hana maʻamau o ke kaula, ʻo 70 ℃ ka wela o ka conductor no ka PVC insulation a me 90 ℃ no XLPE insulation.
B) ʻO ka wela kiʻekiʻe loa o ka mea alakaʻi i ka wā pōkole (ʻaʻole ʻoi aku ka lōʻihi ma mua o 5 kekona):
PVC insulation -- 160 ℃ no ka mea alakaʻi kea pauku ≤300mm2, 140 ℃ no ka conductor keʻa pauku > 300mm2;Hoʻopili ʻia ka hoʻokaʻawale PVC ma 250 ℃.
C) I ke kau ʻana i nā kaula, ʻaʻole e emi ka mahana ambient ma mua o 0 ℃, a ʻo ka liʻiliʻi liʻiliʻi i ʻae ʻia e like me kēia:
ʻO ke kaula kumu hoʻokahi: 20D ponoʻole, 15D pale kaua
Uea nui-core: 15D no ka mea kaua ole, 12D no ka mea kaua
Kahi: D- anawaena maoli o waho o ke kaula.
D) Ka mana uhaki uwea:
Uea kumu alumini: 40×S (N)
Uea kumu keleawe: 70×S (N)
'Ōlelo Aʻo: S ka huina kea o ka mea hoʻokele

Ke kumu hoʻohālike huahana a me ka manaʻo

YJ: XLPE hoʻokaʻawale
L: Aluminum conductor
V: Puu PVC
32: ʻO ke kaula kila-3 cores
22: ʻO ke kāʻei kila-3 cores
72: Aluminum uea pale kaua-1 kumu
62: Ke kila kila lipine pale kaua-1 kumu
ZR: Paʻa ke ahi
