Ke koho ʻana i ke kelepona kūpono: He alakaʻi i nā ʻokoʻa YJV Cable a me RVV Cable.

I ka wā e pili ana i nā kaula uila, ʻo ke koho ʻana i ke ʻano kūpono he mea koʻikoʻi no ka palekana, ka hana, a me ka hilinaʻi. ʻElua ʻano uea maʻamau āu e hālāwai aiYJV uweaaRVV uwea. ʻOiai ua like paha lākou i ka nānā mua ʻana, ua hoʻolālā ʻia lākou no nā kumu like ʻole. E wāwahi kākou i nā ʻokoʻa koʻikoʻi ma ke ala maʻalahi a pololei.

1. Nā helu Voltage like ʻole

ʻO kekahi o nā ʻokoʻa nui loa ma waena o nā kaula YJV a me RVV ʻo kā lākou helu voltage.

• Uea RVV: Ua helu ʻia kēia kelepona no300/500V, he mea kūpono ia no nā noi haʻahaʻa haʻahaʻa, e like me ka hoʻohana ʻana i nā mea hana liʻiliʻi a i ʻole ka hoʻopili ʻana i nā ʻōnaehana palekana.
• YJV Uea: Ma ka ʻaoʻao ʻē aʻe, hiki i nā kaula YJV ke mālama i nā voltage kiʻekiʻe aʻe, mai ka0.6/1kVno nā ʻōnaehana haʻahaʻa haʻahaʻa i6/10kV a i ʻole 26/35kVno ka hoʻoili mana waena-voltage. Hoʻolilo kēia iā YJV i ke koho no ka hoʻoili mana ʻenehana a i ʻole ka nui.

2. Na ano like ole

ʻOkoʻa nā uwea RVV a me YJV inā ʻike ʻoe i ka mea e nānā ai:

• Uea RVV: Hoʻohana pinepine ʻia kēia mau mea i nā ʻōnaehana nāwaliwali o kēia manawa a me nāʻelua a ʻoi aʻe paha core i hui pū ʻia me kahi puʻu PVC. Hiki iā ʻoe ke loaʻa iā lākou ma nā hoʻonohonoho e like me 2-core, 3-core, 4-core, a i ʻole 6-core cables. Hiki ke wili pū ʻia nā cores o loko no ka maʻalahi, e maʻalahi kēia mau kaula e hana pū me nā hoʻonohonoho hale a i ʻole nā ​​​​mea liʻiliʻi.
• YJV Uea: Hōʻike nā kaula YJV ake kumu keleawe i hoʻopuni ʻia e ka XLPE (cross-linked polyethylene) insulationa me kahi pahu PVC. ʻAʻole like me RVV, ua hoʻonohonoho maʻamau ʻia nā core keleawe ma nā kaula YJV i nā laina pololei, ʻaʻole wili. Hāʻawi ka papa waho i kahi nānā maʻemaʻe a paʻa, a ua manaʻo ʻia kēia mau kaula i ʻoi aku ka maikaʻi o ke kaiapuni ma muli o kā lākou mea insulation.

3. Mea like ole

Hoʻohana nā kaula ʻelua i ka PVC no ko lākou mau ʻūhā waho, akā ʻokoʻa kā lākou mea insulating a me nā waiwai.

• Uea RVV: He mau uwea hikiwawe keia, me ka insulation PVC e hoomalu ana. Maikaʻi lākou no nā kaiapuni haʻahaʻa haʻahaʻa a me nā hana maʻalahi, e like me ka hoʻopili ʻana i nā kukui hale a i ʻole nā ​​​​mea liʻiliʻi.
• YJV Uea: Hoʻonui kēia mau uwea iā iaXLPE hookui, ʻo ia ka wela a ʻoi aku ka lōʻihi. Hāʻawi ka XLPE insulation i nā kaula YJV i hiki ke kū i nā mahana kiʻekiʻe a me nā ukana kaumaha, e hoʻolilo iā lākou i kūpono no nā noi ʻoihana a i waho paha.

4. Hana Hana

ʻO ke ʻano o ka hana ʻia ʻana o kēia mau kaula e hoʻokaʻawale iā lākou:

• Uea RVV: Hoʻokaʻawale ʻia ma ke ʻano he uwea plastik, ʻaʻole e hele nā ​​​​kauwela RVV i nā lāʻau lapaʻau hou. He maʻalahi kā lākou PVC insulation akā pono no ka hoʻohana haʻahaʻa haʻahaʻa.
• YJV Uea: ʻO kēia mau kaulapili kea, 'o ia ho'i, e hana 'ia kā lākou mea insulating i kahi ka'ina hana kūikawā no ka ho'omaika'i 'ana i ka wela a me ka lō'ihi. ʻO ka "YJ" ma ko lākou inoa ke kū neipolyethylene pili kea, oiai ka "V" e hoike ana i kaPuu PVC. ʻO kēia hana hou i ka hana ʻana e hana i nā kaula YJV i kahi koho maikaʻi loa no nā kaiapuni koi.

5. Nā Kūlana Noi

Eia kahi e lilo ai ka ʻokoʻa i mea kūpono—no ke aha kēia mau kaula i hoʻohana maoli ʻia?

• Nā polokalamu kelepona RVV:
  Pono nā kaula RVV no nā hana haʻahaʻa haʻahaʻa a i ʻole nā ​​​​hōʻailona hoʻouna, e like me:
  • Hoʻohui i ka palekana a i ʻole nā ​​ʻōnaehana pale anti-theft.
  • ʻO nā ʻōnaehana intercom uwea ma nā hale.
  • Nā pili kukui hale.
  • ʻO nā mea hana a me ka hoʻokele hōʻailona hoʻoili.
• Nā polokalamu kelepona YJV:
  ʻO nā kaula YJV, ʻoi aku ka ikaika, ua hoʻolālā ʻia no ka hoʻoili mana i nā kūlana kiʻekiʻe. ʻO ka hoʻohana maʻamau ka:
  • ʻO nā laina hoʻoili mana a me nā laina hoʻolaha no nā ʻoihana ʻoihana.
  • Hoʻonohonoho paʻa i lokonā pā uwea, auwai, a pa.
  • ʻO nā noi kahi e koi ʻia ai ka volta kiʻekiʻe a me ka pale wela.

6. Nā Kiʻi Takeaways

E hōʻuluʻulu:

• E koho iā RVVinā ʻoe e hana ana i nā hana haʻahaʻa haʻahaʻa, mana haʻahaʻa e like me ka hoʻopili ʻana i nā kukui o ka hale, nā ʻōnaehana palekana, a i ʻole nā ​​mea liʻiliʻi. He maʻalahi, maʻalahi e hoʻohana, a kūpono no nā ʻōnaehana nāwaliwali o kēia manawa.
• E koho iā YJVi ka wā e pili ana i nā voltage kiʻekiʻe a me nā kaiapuni ʻoi aku ka paʻakikī, e like me ka hoʻoili ʻana i ka mana ʻenehana a i ʻole nā ​​​​hoʻonohonoho waho. ʻO kona hoʻokaʻawale ʻana XLPE paʻa a me ka mana uila kiʻekiʻe e lilo ia i mea palekana a hilinaʻi hoʻi no nā noi kaumaha.

Ma ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o nā kaula YJV a me RVV, hiki iā ʻoe ke koho i ka mea kūpono no kāu papahana. A inā ʻaʻole maopopo ʻoe, e ʻoluʻolu e hoʻopili iāʻO Danyang Winpower. Ma hope o nā mea a pau, pili ka palekana a me ka pono i ka loaʻa ʻana o ka pono!
