He aha nā uwea i hoʻohana ʻia ma nā moku a me nā paepae waho?ʻO kēia ka hoʻolauna ʻana i nā ʻano o nā uwea mana i hoʻohana ʻia ma nā moku a me nā paepae o waho.
1. Ke kumu:
He kūpono kēia ʻano uwea no ka lawe ʻana i ka mana ma nā ʻōnaehana mana me ka volta helu AC o 0.6/1KV a ma lalo o nā moku kahawai a me nā moku moana, ka aila waho a me nā hale wai ʻē aʻe.
2. Kuhikuhi maʻamau:
IEC60092-353 1KV～3KV a ma lalo i hoʻokuʻu ʻia i nā kaula mana moana paʻa paʻa.
3. E hoʻohana i nā hiʻohiʻona:
Hana wela: 90 ℃, 125 ℃, etc.
Uo U0/U: 0.6/1KV
ʻAʻole liʻiliʻi ma mua o 6 manawa o ke anawaena o waho o ke kaula
ʻAʻole emi ke ola o ke kaula ma mua o 25 mau makahiki.
4. Nā hōʻailona hana:
ʻO ke kūpaʻa DC o ka mea hoʻokele ma 20 ° C e hālāwai me ka maʻamau IEC60228 (GB3956).
ʻAʻole i emi iho ka pale insulation o ke kaula ma 20 ° C ma mua o 5000MΩ·km (ʻoi aku ka kiʻekiʻe ma mua o ka helu hana o ke kūpaʻa insulation e koi ʻia e ka maʻamau IEC60092-353).
Hoʻokō ka hana hoʻopaʻa ahi i nā koi o IEC60332-3-22 Class A flame retardant (ke ahi no 40 mau minuke, a ʻaʻole ʻoi aku ke kiʻekiʻe o ka carbonization o ke kaula 2.5m).
No nā uwea pale ahi, hoʻokō kā lākou hana pale ahi i ka IEC60331 (90 mau minuke (puʻu ahi) + 15 mau minuke (ma hope o ka wehe ʻana i ke ahi), wela wela 750 ℃ (0 ~ +50 ℃) maʻamau ka lako uila, ʻaʻohe uila).
ʻO ka index halogen-free haʻahaʻa haʻahaʻa o ke kaula e hoʻokō i nā koi o IEC60754.2, ʻaʻole i ʻoi aku ka hoʻokuʻu kinoea halogen ma mua o 5mg / g, ʻo ka ʻike kikoʻī o kāna waiwai pH ʻaʻole i emi iho ma mua o 4.3, a ʻaʻole ka conductivity. ʻoi aku ma mua o 10μs / mm.
ʻO ka hana ʻana o ka uahi haʻahaʻa o ke kaula: ʻAʻole liʻiliʻi ka nui o ka uahi (transmittance māmā) o ke kaula ma lalo o 60%.E hoʻokō i nā koi maʻamau o IEC61034.
5. Hoʻolālā kelepona
Hana ʻia ka conductor me ke keleawe annealed tinned kiʻekiʻe.ʻO kēia ʻano conductor he hopena anti-corrosion maikaʻi loa.Hoʻokaʻawale ʻia ka ʻōnaehana conductor i nā conductors paʻa, nā conductors stranded a me nā conductors palupalu.
Hoʻohana ka insulation i ka extruded insulation.Hiki i kēia ʻano extrusion ke hōʻemi i ke kinoea ma waena o ka conductor a me ka insulation e pale ai i ke komo ʻana o nā mea haumia e like me ka mahu wai.
Hoʻokaʻawale ʻia ke code kala ma ke kala.Hiki ke koho ʻia nā kala e like me nā pono o ka pūnaewele no ka hoʻokomo maʻalahi.
ʻO ka puʻu o loko/liner (Jacket) kahi mea haʻahaʻa haʻahaʻa halogen me ka hoʻopaʻa ahi kiʻekiʻe.ʻAʻohe halogen ka mea.
ʻO ke kapa kila (Armor) he ʻano wili.ʻOi aku ka maʻalahi o kēia ʻano pale kaua a maʻalahi hoʻi no ka waiho ʻana i ke kaula.ʻO nā mea kila kila i hoʻopaʻa ʻia me ka uea keleawe tinned a me ka uea kila galvanized, ʻo ia mau mea ʻelua he hopena anti-corrosion maikaʻi.
ʻO ka mea o waho (Sheath) he mea haʻahaʻa ʻole halogen.ʻAʻole hoʻopuka kēia i ke kinoea ʻawaʻawa i ke ahi a hoʻopuka iki i ka uahi.Hoʻohana ʻia ia ma nā wahi ākea.
Hiki ke paʻi ʻia ka ʻike ʻana o ke kaula e like me nā pono maoli.
6. Ke kumu hoʻohālike uea:
1. XLPE insulated haʻahaʻa-uwahi halogen-noa waho sheathed uea kükohu:
CJEW/SC, CJEW/NC, CJEW95(85)/SC, CJEW95(85)/NC,
2. EPR insulated haʻahaʻa halogen-noa waho sheathed uwea kükohu:
CEEW/SC, CEEW/NC, CEEW95(85)/SC, CEEW95(85)/NC,
3. Hōʻike hoʻohālike:
C- 'o ia ho'i ke kaula mana moana
J-XLPE hookui
E-EPR (Ethylene Propylene Rubber Insulation)
EW-uhi haʻahaʻa halogen puʻu polyolefin
95- ʻO nā mea kaua i hoʻopaʻa ʻia i ka uea kila kila a me ka LSZH puʻu waho (ʻaʻole i emi iho ma lalo o 84%).
85 - ʻO nā mea kaua i hoʻopaʻa ʻia i ka uea keleawe tinned a me ka LSZH puʻu waho (ʻaʻole i emi iho ma lalo o 84%).
ʻO ka hana pale ahi o ka SC-cable e hui me IEC60332-3-22 Class A i ka lapalapa ahi, a ʻo ka mea halogen ma lalo o 5mg/g.
NC - ʻO ke kūpaʻa ahi o ke kaula e hui me IEC60331, a ʻoi aku ka nui o ka halogen ma mua o 5mg / g.
