ASTM 25kV Aerial Spacer Cable AAC 3-layer Track-resistant XLPE
HOOLAHA
Palapala noi
I mea e pale aku ai i nā hewa pili a i nā kūlana i uku nui ʻia ka lewa, ua hoʻolālā ʻia ʻo ASTM 25kV Aerial Cable (ka uea lāʻau a me ka spacer cable) no ka hoʻohana ʻana i nā ʻōnaehana hoʻoili mua a me ka lua i helu ʻia ma 25 kV (nominal).
Inā pili me nā kumulāʻau a i ʻole nā holoholona hihiu ʻē aʻe, hoʻopau ka ʻōnaehana 3-layer kūpaʻa i nā ala pōkole a me nā uila uila.Hiki i kēia ʻōnaehana ke hoʻopau pono i nā hemahema o ka ʻōnaehana, pōʻino, a i ʻole ke ahi i hoʻokumu ʻia e nā kumulāʻau a i ʻole nā lālā hāʻule ke kau pono ʻia.
Kūkulu
ʻO Aerial Spacer Cable me kahi mea hoʻokele i hana ʻia me ka aluminika, kahi pale extruded 3-layer a me ka ʻōnaehana uhi i hana ʻia me kahi uhi 2-layer a me kahi pale semiconducting thermoset conductor extruded.
Hana ʻia ka polyethylene crosslinked i ka papa o loko o ka uhi, a ʻo ka polyethylene crosslinked track-resistant ka papa waho.
Hoʻohui ʻia kēlā me kēia papa me kahi paʻa.
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 kūlana
E like me nā kikoʻī i hōʻike ʻia e ka American Society for Testing and Materials:
ʻO nā ʻāpana alumini 1350-H19 conductor o kēia huahana e hui a ʻoi aku paha ma mua o nā kūlana B230 no nā mea i ʻōlelo ʻia.
Hoʻopili pū nā ʻāpana conductor i ka maʻamau B231 no nā uea alumini concentric-lay-stranded 1350-H19.
ʻO ke kila alumini concentric-lay-stranded (ACSR) i hoʻokō i nā kūlana B232.
ʻO ke kila kila i hoʻopaʻa ʻia i ka zinc-coated no ka hoʻoikaika ʻana e hoʻokō i nā kūlana ASTM B498.
