Hoʻohana nui ka ʻoihana i ka pepa aramid Z955 a me ka pepa honeycomb aramid Z953. Ma ke kahua o ka insulation uila ma ke kaʻaahi kaʻaahi, Z955 pepa aramid i hoʻohana ʻia ma ke ʻano he kumu insulation mea nui no ka traction motors, transformers a me nā mea uila ʻē aʻe, hiki ke hoʻomaikaʻi nui i ka hana palekana a me ke ola lawelawe. Loaʻa iā ia ka insulation uila maikaʻi a me ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa overload ikaika, a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma luna o 200 ℃. Hiki iā ia ke hōʻemi nui i ka hoʻolālā leo o nā kaʻa a me nā mea hoʻololi, a hoʻohana ʻia e like me ka mea insulation nui no nā ʻōnaehana insulation, hoʻohana nui ʻia i nā ʻāpana koʻikoʻi e like me nā motika traction a me nā mea hoʻololi i ke kaʻa kaʻa, e like me ka insulation slot, ground insulation, phase insulation, wire. ka hoʻokuʻu ʻana, a me ka hoʻokaʻawale ʻana.

Ma ke kahua o ke kaʻaahi kaʻa māmā, hiki ke hoʻohana nui ʻia ka ʻōnaehana sanwic aramid honeycomb i hoʻomākaukau ʻia e Z953 i nā kahua e like me nā kaʻa maglev, nā kaʻa kaʻa kiʻekiʻe, nā subways, nā kaʻa māmā, etc. nā mea ʻē aʻe o nā kaʻaahi. Hiki i kona hoʻohana ke hoʻemi i ke kikowaena o ka umekaumaha o ke kaʻa, a me ka ukana ma nā axles a me nā alahele, ʻoiai e hōʻemi ana i ke kaumaha o ke kaʻa a hoʻonui i ka wikiwiki o ke kaʻa.
