Hoʻohana nui ka ʻoihana i ka pepa aramid Z955. ʻO ka pepa aramid Z955 he pepa insulating i ʻōwili ʻia a hoʻonani ʻia i ka wela wela. Hana ʻia ia mai nā fila aramid maʻemaʻe e ka milo pulu a me ke kaomi wela wela. Loaʻa iā ia ke kūpaʻa kiʻekiʻe kiʻekiʻe, ka insulation uila maikaʻi loa, nā waiwai mechanical, a me ka retardancy ahi, ka maʻalahi a me ka pale ʻana i ka waimaka, ka paʻa kemika maikaʻi a me ka hoʻohālikelike ʻana, ka launa maikaʻi me nā ʻano pena insulation, a me ke kūpaʻa ʻaila maikaʻi. Hiki ke hoʻohana pū me ka H-grade a me ka C-grade insulation system no ka hoʻohana lōʻihi ma 200 ℃. Ua kūpono ʻo Z955 i nā manawa i ʻike ʻia e koi ana i nā mea hoʻokalakupua uila ʻano pepa, a hiki ke hana ma lalo o ka overload pōkole me ke kūpaʻa overload ikaika. Hiki ke hoʻohana 'ia no ka inter-turn insulation, interlayer insulation, a me ka hopena insulation o nā transformers like 'ole (mining explosion-proof transformers, power transformers, reactors, rectifiers, etc.), a me ka slot insulation, inter turn insulation, phase insulation, a ka pad insulation o na kaa like ole (mining, metallurgical, shipbuilding, etc.) and generators. Eia kekahi, hoʻohana nui ʻia ia i nā kahua uila a me nā uila e like me nā ʻeke, nā papa kaapuni, a me nā hoʻololi.
