Nā kikoʻī:

    Ua kūpono nā kaula 25KV no ka hoʻohana ʻana i nā wahi pulu a maloʻo, nā auwai, nā ʻauwaʻa, nā pā, nā pā, ke kanu pololei ʻana i ka wā i hoʻokomo ʻia me kahi mea hoʻokele honua ma kahi kokoke e like me ka NEC pauku 311.36 a me 250.4(A)(5), a ma kahi o ka uila ʻoi aku ka maikaʻi. makemake ʻia nā waiwai.Hiki i kēia mau uwea ke hana mau i ka mahana conductor ʻaʻole iʻoi aku ma mua o 105 ° C no ka hana maʻamau, 140 ° C no ka hoʻouka pilikia, a me 250 ° C no nā kūlana pōkole pōkole.Kuhi ʻia ma -35°C no ka piʻo anu.ST1 (uhi haʻahaʻa) Ua helu ʻia no nā nui 1/0 a nui aʻe.Hana ʻia ka lole PVC me ka ʻenehana SIM a loaʻa ka coefficient o friction COF o 0.2.Hiki ke hoʻokomo ʻia ke kaula i loko o ka conduit me ke kōkua ʻole o ka lubrication.Hoʻoholo ʻia no 1000 lbs./FT kiʻekiʻe o ke kaomi ʻaoʻao ʻaoʻao.

Ke alakaʻi: Papa A a i ʻole B CompressedCconcentric stranded alumini alloy, Aluminum a i ʻolemea lawe keleawe.Hoʻopaʻa ʻia nā conductors stranded i ka wai me ka conductor filling compound.
Pale Pale: Extruded thermosetting semiconducting pale i wehe manuahi ʻia mai ke alakaʻi a hoʻopaʻa ʻia i ka insulation.
Insulation: Extruded, hoʻopiha ʻolePolyethylene hoʻopaʻa ʻia i ka lāʻau (TR-XLPE)e like me ka mea i wehewehe ʻia ma ANSI/ICEA S-94-649 - 133% pae hoʻokaʻawale.
Palekana Insulation: Extruded thermosetting semiconducting pale me ka hoʻopaʻa ʻia ʻana i ka insulation e hāʻawi ana i ke kaulike pono ma waena o ka pono uila a me ka maʻalahi o ka wehe ʻana.
Palekana Metala:Ua hoʻohana ʻia nā uea keleawe paʻa paʻa a hoʻopaʻa ʻia.
Pale Wai: Hoʻohana ʻia nā mea pale wai ma luna o ka pale insulation a puni nā uea kū ʻole e pale aku i ke komo ʻana o ka wai longitudinal.E hoʻāʻo ʻia ke komo ʻana o ka wai lōʻihi e like me ka paʻi hou loa o ICEA T-34-664 koe wale nō ka palena haʻahaʻa he 15 psig no 1 hola.
