Pahū ʻo Shenhai
Pono e hoʻopaʻa ʻia nā lako uila i hoʻonui ʻia i ka palekana i loko o kahi pā i hoʻolālā ʻia. He mea koʻikoʻi kēia casing ʻaʻole wale no ka hui ʻana i nā ʻāpana uila akā no ka pale ʻana iā lākou mai nā hoʻoweliweli o waho e like me nā ʻāpana paʻa., mākū, a me ka wai. He pilikia koʻikoʻi kēia mau mea no ka mea hiki iā lākou ke alakaʻi i nā pōkole pōkole, nā haʻihaʻi insulation, a me nā hoʻokuʻu uila weliweli.
Ua ʻike maikaʻi ʻia nā mea uila e pili ana i nā mea kūlohelohe. ʻO nā mea haumia paʻa, ʻo kahi laʻana, hiki ke hoʻokomo a hoʻopōkole, ʻoiai hiki i ka wai ke hoʻohaʻahaʻa i ka insulation, e alakaʻi ana i nā leaka a me nā huna ahi - he kūlana weliweli maoli. ʻO ka hoʻohana ʻana i nā pā me ka helu palekana kūpono hiki ke pale i kēia mau pilikia.
Wahi a ke kūlana GB4208-2008, e kuhikuhi ana i nā pae palekana o ka pā (IP code), Hōʻike ʻia kēia mau pae e ka IP code a ukali ʻia e nā helu ʻelua a i kekahi manawa nā leka hou. Hōʻike ka helu mua i ka pae o ka pale ʻana i nā mea paʻa, a ʻo ka lua e kūʻē i ka wai. ʻo kahi laʻana, Hāʻawi kahi pā i helu ʻia IP54 i kahi pae o ka pale ʻana i nā mea paʻa a me nā wai. Hoʻokaʻawale ʻo GB4208-2008 i ka pale i nā mea paʻa 6 pae a kūʻē i ka wai i loko 8 pae.
I ka wā e pili ana i nā pā:
Me nā ʻāpana ola i hōʻike ʻia, pono ka palena iki o IP54.
Me nā ʻāpana ola insulated i loko, pono ia ma ka liʻiliʻi loa IP54.

No ka hoolele:
Ma ka papa I lako, ka palena iki o IP54 (no nā ʻāpana ola ʻole-mālamalama) a i ʻole IP44 (no nā ʻāpana ola insulated) koi ʻia.
No na lako Papa II, ʻAʻole e emi ka helu ma lalo o IP44, me ka nānā ʻole i ke ʻano o nā mea i loko.
Inā loaʻa nā mea uila palekana palekana palekana i loko nā kaapuni a i ʻole nā ʻōnaehana, pono e hoʻokaʻawale ʻia kēia mau mea mai nā kaapuni palekana ʻole. Pono e waiho ʻia nā kaapuni palekana ʻole i loko o kahi keʻena me ka liʻiliʻi o ka helu IP30, hoailonaia me ka olelo ao: “Mai wehe i ka mana!”
He mea koʻikoʻi ka paʻa o nā lako uila i hoʻonui ʻia no ka pale ʻana i nā ʻāpana o loko mai ka hoʻopili ʻana o waho a me ka hōʻoia ʻana i ka hana insulation o ka circuitry e paʻa mau., no laila ka huaʻōlelo “hoʻonui-palekana pa.”
