ASTM 35kV Aerial Tree Wire Power Line ACSR 3-layer Track-resistant XLPE
HOOLAHA
Nānā nui
35kV Aerial Overhead Power Line Cable (lāʻau lāʻau a me spacer cable) ACSR (compact) 3-layer track-resistant PE i hoʻohana ʻia ma ka uea lāʻau a i ʻole spacer cable, hana ʻia, hoʻāʻo a kaha ʻia e like me ICEA S-121-733, ka maʻamau no ka Uea Laʻau a me ka ʻelele Kākoʻo Spacer Cable.
Aia kēia ʻōnaehana 3-layer i kahi pale conductor (layer #1), a ukali ʻia e kahi uhi 2-layer (nā papa #2 a me #3).
Palapala noi
Ua manaʻo ʻia ka Uea Line Power Aerial (uea lāʻau a me spacer cable) no ka hoʻohana ʻana i nā ʻōnaehana hoʻolaha mua a me ke kula kiʻekiʻe i helu ʻia he 35 kV (nominal) maʻamau no ka pale ʻana i nā hewa ma muli o ka hoʻopili ʻana a i ʻole ka palena o ka wahi.
ʻO ka ʻōnaehana 3-layer kūpaʻa i ke ala e pale ai i nā pōkole pōkole a me nā flashovers inā pili me nā lāʻau a me nā holoholona hihiu.Ke hoʻokomo pololei ʻia, ʻoi aku ka maikaʻi o kēia ʻōnaehana i ka pale ʻana i nā ʻōnaehana outage, pōʻino, a i ʻole ke ahi ma muli o ka hāʻule ʻana o nā kumulāʻau a i ʻole nā lālā.
Uea Laau
Ke hoʻohana ʻia i loko o kahi ʻōnaehana mana uea lāʻau, ua hoʻokomo ʻia ia ma kahi hoʻonohonoho paʻa, ma ke ʻano like a me ka spacing ma luna o nā insulators e like me nā mea alakaʻi i uhi ʻole a uhi ʻia.ʻO nā mea hoʻokele kākoʻo ponoʻī, e like me ACSR, he mea maʻamau i kēia ʻano hoʻonohonoho.
Uea Spacer
Ke hoʻohana ʻia i loko o kahi ʻōnaehana uila spacer, ua hoʻokomo ʻia me kahi ʻokoʻa like ʻole i loko o kahi hoʻonohonoho daimana i mālama ʻia e spacer hardware.Kākoʻo ʻia ka hui spacer a me ke kaula e kahi ʻelele ʻole, e like me ke kila kila alumini, ACSR, OPGW, a i ʻole uea kila galvanized.
Noho liʻiliʻi ka nui o nā hui uea Spacer, e koi ana i ka haiki loa o ke ala kūpono a i ʻole ke alahele.
Nā kūkulu hale
Hoʻokahi kaula me ka ACSR conductor, he 3-layer extruded pale a me ka uhi ʻōnaehana, i loko o ka extruded semiconducting thermoset conductor pale, a me ka 2-layer uhi.
ʻO ka papa i loko he polyethylene crosslinked (XLPE), aʻo ka papa waho he polyethylene crosslinked track-resistant (TK-XLPE).
Hoʻopili ʻia nā papa a pau.
Mea alakaʻi:
AAC (1350-H19, paʻa paʻa).
Palekana alakaʻi:
ʻO ka pale thermoplastic semiconducting extruded i wehe manuahi ʻia mai ke alakaʻi a hoʻopaʻa ʻia i ka uhi.
Ka uhi o loko a me waho:
Uhi polyethylene crosslinked 2 (XLPE), kahi o ka papa o waho e kūpaʻa-track (TK-XLPE).Hoʻopili ʻia nā papa a pau.He ʻeleʻele a ʻeleʻele paha ka ʻaoʻao o waho, pale i ka lā a pale i ke ala.
Nā kikoʻī
Hana ʻia kēia mau kaula a hoʻāʻo ʻia e hoʻokō a ʻoi aku paha ma mua o nā kūlana aʻe:
- ASTM B230 – Aluminum 1350–H19 Uea no nā Hana Uila
- ASTM B231 – Concentric-Lay-Stranded Aluminum 1350 Conductors
