ʻO EMI Shielding Braided Layer e ka hui ʻana i nā uea keleawe ʻole a i ʻole
wehewehe huahana
ʻO ka walaʻau uila ke ʻano o ka ikehu electromagnetic i hoʻokahe ʻia e nā mea uila e like me nā mīkini hoʻomaʻemaʻe, nā mea hana, nā mea hoʻololi, nā mana relay, nā laina mana a me nā mea ʻē aʻe. .
I mea e hoʻopaʻa pono ai i ka hana pono o kahi mea uila, e mālama ʻia i ka leo i makemake ʻole ʻia. ʻO nā ʻano kumu (1) pale, (2) noʻonoʻo, (3) absorption, (4) bypassing.
Mai ka hiʻohiʻona o ke alakaʻi, ʻo ka papa pale e hoʻopuni mau i nā conductors lawe mana, e hana ma ke ʻano he hōʻike no ka radiation EMI a ma ka manawa like, ma ke ʻano he ala e alakaʻi ai i ka leo i ka honua. No laila, no ka mea, ʻo ka nui o ka ikehu e hiki aku i ka conductor i loko e attenuated e ka pale pale, hiki ke hoʻemi nui ʻia ka mana, inā ʻaʻole e hoʻopau loa. ʻO ke kumu attenuation e pili ana i ka pono o ka pale. ʻOiaʻiʻo, hiki ke koho ʻia nā degere like ʻole o ka pale e pili ana i ke kiʻekiʻe o ka walaʻau i ke kaiapuni, ke anawaena, ka maʻalahi a me nā mea pili ʻē aʻe.
ʻElua ala e hana ai i kahi pale pale maikaʻi i nā conductors. ʻO ka mea mua ma o ka hoʻohana ʻana i kahi ʻāpana alumini ʻeleʻele ʻeleʻele e hoʻopuni ana i nā conductors a ʻo ka lua ma kahi ʻāpana wili. Ma ka hoʻopili ʻana i nā uea keleawe ʻole a i ʻole ke kani ʻana, hiki ke hana i kahi papa maʻalahi a puni nā conductors. Hāʻawi kēia hāʻina i ka maikaʻi o ka maʻalahi o ka hoʻopaʻa ʻia ʻana, ke crimped ke kaula i kahi mea hoʻohui. Eia nō naʻe, ʻoiai ke hōʻike nei ka braid i nā wahi ākea liʻiliʻi ma waena o nā uea keleawe, ʻaʻole ia e hāʻawi i ka uhi piha. Ma muli o ka paʻa o ka ulana, ʻo nā pale pale maʻamau e hāʻawi i kahi uhi mai 70% a 95%. Ke paʻa ke kaula, 70% ka mea maʻamau. ʻAʻole hiki i ka uhi ʻili kiʻekiʻe ke lawe mai i ka pono pale kiʻekiʻe. No ka mea, ʻoi aku ka kiʻekiʻe o ka conductivity o ke keleawe ma mua o ka alumini a ʻoi aku ka nui o ka braid no ka hoʻokō ʻana i ka walaʻau, ʻoi aku ka maikaʻi o ka braid e like me ka pale i hoʻohālikelike ʻia me ka papa foil.
