Hoʻouna i kahi leka uilaHe kūpono nā kaula mana waena-voltage 19-33kV XLPE-insulated no nā pūnaewele hoʻolaha a i ʻole nā pūnaewele hoʻoili lua, e lawelawe pinepine ana ma ke ʻano he lako mana mua no nā pūnaewele kalepa, ʻoihana, a me nā hale noho kūlanakauhale. He kūpono lākou no nā ʻōnaehana au hewa kiʻekiʻe me nā au hewa i helu ʻia a hiki i 10kA/1 kekona. Hiki ke hāʻawi ʻia nā hale me ka mana au hewa kiʻekiʻe ma ke noi.
Kūkulu ʻana:
Mea alakaʻi:ʻO nā koho e komo pū me ke keleawe a i ʻole ka alumini i wili ʻia, paʻa a paʻa.
Palekana alakaʻi:He hui semi-conductive i hoʻopili ʻia ma ka extrusion ma luna o ke alakaʻi.
Hoʻokaʻawale:ʻO ka hui polyethylene cross-linked (XLPE) e kūlike ana me AS/NZS 3808. Hāʻawi ʻo XLPE i ke kūpaʻa wela maikaʻi loa a me ke kūpaʻa ʻana i ka ʻāʻī ʻana i hoʻohālikelike ʻia me PVC.
Palekana hoʻokaʻawale:ʻO ka hui semiconductive i hoʻopuka ʻia e uhi ana i ka papa insulation.
Ka mahana hana kiʻekiʻe loa:Hiki i nā alakaʻi ke hana ma ka mahana mau loa o 90°C.
Ka mahana pōkole kiʻekiʻe loa:Hiki i ke kaula ke kū i ka mahana pōkole kiʻekiʻe loa o 250°C a hiki i 5 kekona.
Pale hao:Hana pinepine ʻia mai ka uea keleawe annealed maʻemaʻe a i ʻole ka lipine keleawe.
Nā mea kaua hao:ʻO nā mana i hoʻopaʻa ʻia me ka pale kaua e komo pū me ka uea kila galvanized (SWA) no nā kaula multi-core a me ka uea alumini (AWA) no nā kaula hoʻokahi-core.
Mea Uhi:
ʻO ka ʻūpā maʻamau he hui PVC ʻeleʻele 5V-90.
He kūpono nā koho ʻē aʻe LSZH (Low Smoke Zero Halogen) no loko, nā wahi lehulehu, a i ʻole nā wahi ʻē aʻe e pono ai nā noʻonoʻo palekana ahi.
Hiki ke hoʻohui ʻia kahi ʻaʻahu polyamide (nylon) i extruded no ke kūpale ʻana i ka ʻanuʻu.
Hiki ke hoʻohana ʻia ka uhi waho HDPE (High-Density Polyethylene) ma ke ʻano he koho ʻē aʻe.
