ʻO ke ʻano o nā kaula mana moana
ʻO ka mea maʻamau, ʻo ke kaula mana he conductor (cable core), kahi insulating layer (hiki i ka layer insulating ke kū i ka volta o ka mānoanoa), kahi hoʻopiha a me ka pale pale (hana ʻia me ka semiconductor a i ʻole nā mea metala), kahi sheath (mālama i ka insulation. waiwai o ke kaula) mai loko a waho.) a me nā ʻāpana nui ʻē aʻe, ʻo ka maikaʻi o kāna hana insulation e pili pono i ka hana palekana a paʻa o ka ʻōnaehana uila holoʻokoʻa.No laila, ʻo IEEE, IEC/TC18 a me nā kūlana honua ʻē aʻe i kuhikuhi maopopo i ka hana o ke kaula.

Ma muli o nā hiʻohiʻona o ka conductivity uila kiʻekiʻe a me ka ikaika mechanical kiʻekiʻe o nā conductors keleawe, hoʻohana ʻia ke keleawe ma ke ʻano he kumu conductor i nā kaula mana moana.Uea.Hoʻokaʻawale ʻia nā alakaʻi kelepona i ke ʻano hoʻopiʻi a me ke ʻano non-compression e like me ke kaʻina hana.ʻO ka mea hoʻokele kelepona i hoʻopaʻa ʻia he ʻano paʻa, hiki ke mālama i nā mea waiwai a hoʻemi i nā kumukūʻai, akā ʻaʻole he pōʻai maʻamau ke alakaʻi hoʻokahi, e like me ka mea i hōʻike ʻia ma ka Figure 1. Ma waho aʻe o nā mea hoʻokele me nā ʻāpana liʻiliʻi liʻiliʻi, hoʻopaʻa pinepine ʻia nā alakaʻi kaula. hiki ke hōʻoia i ka loli kiʻekiʻe a me ka liʻiliʻi ikaika o ke kaula, a ʻaʻole hiki ke hōʻino i ka insulation a me ka deformation plastic.Mai ka hiʻohiʻona o ke ʻano o ke kaula, hiki ke hoʻokaʻawale ʻia nā conductors stranded i ke ʻano o ka peʻa, ka pōʻai, ka pōʻai hollow a pēlā aku.E like me ka helu o ka uwea conductor cores, uwea hiki ke maheleia i hookahi-core uwea a me multi-core uwea.E ʻike iā GB3956 no nā ʻōlelo kikoʻī e pili ana i ka helu a me ke anawaena nominal.

ʻO ka maikaʻi o ka insulation a me ke kiʻekiʻe o nā kaula mana moana he mea koʻikoʻi i ke ola lawelawe o nā kaula e pili ana i ke ʻano.Hoʻokaʻawale ʻia nā kaula mana moana e like me nā ʻano insulation maʻamau, e like me ka mea i hōʻike ʻia ma ke kiʻi.ʻO ka mānoanoa a me nā waiwai mechanical o nā ʻano like ʻole o ka insulation cable i wehewehe ʻia ma GB7594.
