Hoʻouna i kahi leka uila19/33kV XLPE-insulated medium-voltage uwea mana kūpono no nā pūnaewele ikehu e like me nā mana mana. No ka hoʻokomo ʻana i nā ducts, lalo a me waho. Hiki ke hoʻohana ʻia no nā hoʻonohonoho paʻa i loko o nā ʻupena hoʻolaha, nā wahi ʻoihana, a me nā kikowaena mana. E ʻoluʻolu e hoʻomaopopo: Hiki i ka ʻulaʻula ʻulaʻula ke hele a mae ke ʻike ʻia i nā kukuna UV. Hana ʻia nā kaula uila me ka hoʻohana ʻana i ke kaʻina monosil. Hāʻawi mākou i ka mea kanu kūikawā nui, nā keʻena noiʻi hou a me nā kaʻina hana hoʻomalu maikaʻi e koi ʻia no ka hana ʻana i nā kaula i hoʻopaʻa ʻia PVC no ka hoʻohana ʻana a hiki i 6KV a me XLPE / EPR i hoʻopaʻa ʻia no ka hoʻohana ʻana i nā volta a hiki i 35 KV. Mālama ʻia nā mea āpau i nā kūlana hoʻomaʻemaʻe i ka wā o ke kaʻina hana i mea e hōʻoia ai i ka homogeneity piha o nā mea insulation i hoʻopau ʻia.
