Kaula MCPTJ: Ke Kaula Mining Koʻikoʻi no nā Kaiapuni Pōʻino

Hoʻolauna

ʻO kaUea MCPTJhe mea kūikawā Uea ʻeli i hoʻolālā ʻia no ka hoʻohana ʻana i nā lua lanahu ma lalo o ka honua a me nā wahi ʻoihana ʻē aʻe e pilikia nui ana. ʻIke ʻia no kānanā waiwai pale ahi, ka lōʻihi o ka mīkini, a me ka hoʻolālā maʻalahi, hōʻoia kēia kaula i ka hoʻoili mana palekana a hilinaʻi hoʻi i nā kūlana paʻakikī.

1. He aha ke kaula MCPTJ?

MCPTJhekaula mining palupalu i uhi ʻia me ka laholiohoʻohana nui ʻia i nā lua lanahu, ke eli ʻana i nā tunnels, a me nā noi ʻoihana kaumaha. Ua haki ka inoa penei:

M– ʻEli ʻana

C– Alakaʻi keleawe

P– ʻO ka pale ʻana o ka laholio (ʻo ia hoʻi ʻo EPR a i ʻole CSP)

T– ʻUpena laholio paʻa (chloroprene a i ʻole like)

ʻO J– Alakaʻi honua hou aʻe

Ua helu ʻia no0.66/1.14 kV, ʻo ia hoʻi hiki iā ia ke lawelawe660V pae-a-honua a me 1.14kV pae-a-paenā voltages, e lilo ia i mea kūpono noka hoʻoikaika ʻana i nā mīkini mining, nā mea hoʻoili, a me nā lako wili.

2. Nā Hiʻohiʻona Koʻikoʻi a me ke Kūkulu ʻana

A. Alakaʻi

Mea HanaKeleawe kini (no ke kūpale ʻana i ka palaho)

Ka maʻalahi: Nā alakaʻi kaulahao papa 5 (no kēlā me kēiaIEC 60228)

Kumu Hoʻoheheʻe HonuaHoʻokomo pū ʻia kahi alakaʻi keleawe ʻōlohelohe no ka hoʻopili palekana ʻana

B. Hoʻokaʻawale ʻana

ʻEthylene Propylene Rubber (EPR)a i ʻoleʻO ka Polyethylene Chlorosulfonated (CSP)

Kūpaʻa ika ʻaila, ka makū, a me ka ʻānai ʻana

C. ʻUhi

ʻO ka laholio chloroprene hana kaumaha (CR)

Mea pale ahi(hālāwaiMT 818a meIEC 60332)

Haʻahaʻa ka uahi a ʻaʻohe halogen(no kēlā me kēiaIEC 60754 a me 61034)

D. Nā Hiʻohiʻona Koho

Pale kaua uea kila(no ka palekana mīkini keu)

Palekana EMI(lipine keleawe a ulana paha no ke kū'ē'ē i ke komohewa)

3. Nā Kūlana ʻenehana a me nā Palapala Hōʻoia

Ua kūlike nā kaula MCPTJ me:

Kina:MT 818.5-2009(Nā kaula eli pale ahi)

Honua:

IEC 60502-4(Nā uwea mana no ka hana ʻeli ʻana)

MSHA(ʻOihana Hoʻomalu Palekana a me ke Ola Kino o ʻAmelika Hui Pū ʻIa)

ATEX/IECEx(No nā lewa pahū)

Nā Hoʻāʻo Koʻikoʻi:

Ke kū'ē ʻana i ka lapalapa(IEC 60332-1/2)

Ke kūpaʻa ʻaila a me ke kemika(IEC 60811)

Hoʻāʻo kūlou a me ke kūlou(IEC 60228 Papa 5)

4. Nā noi ma nā wahi ʻeli a me nā wahi pōʻino

Hoʻohana nui ʻia nā kaula MCPTJ i:
✔Nā lua lanahu ma lalo o ka honua(nā mea ʻokiʻoki, nā mea hoʻoili, nā pamu)
✔Nā lako hana ʻeli a me ka hana ʻeli ʻana
✔Nā mīkini ʻeli ʻaila a me ke kinoea(nā wahi ʻino a ʻinoʻino)
✔Nā mīkini hana ʻeli lawe lima(ma muli o ke kūlou kiʻekiʻe)

No ke aha i makemake nui ʻia ai?

ʻOi aku ka palekana ma mua o Nā Uea PVC(ʻaʻole e hoʻopuka i nā uahi ʻawahia i ka wā e puhi ʻia ai)

ʻOi aku ka paʻa ma mua o ke kūlana maʻamau Kaula laholionā(kū i ka ʻoki ʻana, ka ʻānai ʻana, a me ka wāwahi ʻana)

ʻOi aku ka maikaʻi o ka maʻalahima mua o nā kaula pale kaua e like meNYRY
