Ka ʻike o ka laina uila kiʻekiʻe post porcelain insulator
ʻO ka laina pou insulator he ʻano insulator ʻoʻoleʻa i haku ʻia me hoʻokahi a ʻoi aʻe paha mau ʻāpana insulating i hoʻopili mau ʻia ma ke kumu metala a i kekahi manawa he pāpale, a hiki ke hoʻopaʻa paʻa ʻia ma luna o ke kahua kākoʻo me nā bolts stud a i ʻole hoʻokahi a ʻoi aku paha nā bol i hoʻokomo ʻia ma ke kumu metala.Hoʻohana ʻia ia no ka insulating a me ke kākoʻo ʻana i nā conductors i nā laina mana AC me ka voltage nominal ʻoi aku ka kiʻekiʻe ma mua o 1000V, ke alapine ma lalo o 100Hz a me ke kiʻekiʻe ma lalo o 1000m ma nā wahi maʻamau a me nā wahi haʻahaʻa a me ke kaumaha.ʻO ka mahana wela o kona kahua hoʻokomo ma waena o - 40 ℃ a me ~ + 40 ℃.
Hiki i ka laina (solid) post insulator ke pani i ka pin insulator.ʻO ka pin insulator kahi ʻano B insulator, hiki ke hoʻopau i ka wā e hana ai.E haʻihaʻi ka insulator aniani paʻakikī iā ia iho i kēia manawa, ʻoiai ʻaʻole e haki ka insulator porcelain.No laila, pono ka ʻoihana mana e hoʻolilo i ka nui o nā manpower a me nā kumuwaiwai no ka ʻike uila a me ka hoʻāʻo pale ʻana i nā insulators porcelain, aia kekahi mau hemahema i ka hoʻokele waiwai a palekana.No laila, me ka hoʻomohala ʻana i ka ʻenehana hana, ua puka mai nā laina (solid) post insulators.He insulator paʻa kēia ʻano insulator a no ke ʻano insulator.No laila, ʻaʻohe pono e hopohopo e pili ana i ka haki ʻana ma ka ʻaoʻao o ka insulator i ka wā o ka hana, ʻo ia kekahi o kāna mau pono.
E like me ka helu ʻana o ka uila impulse e kū i ka uila, ua māhele ʻia ka laina post porcelain insulator i ʻewalu mau papa: 95, 105, 125, 150, 170, 200, 250 a me 325kv;E like me ka helu ʻana i ka hāʻawi ʻole ʻana, ua māhele ʻia i ʻehā mau papa: 3, 5, 8 a me 12.5kn;E like me kāna ʻano hoʻonohonoho, hiki ke hoʻokaʻawale ʻia i ka hoʻonohonoho kū a me ka hoʻonohonoho ʻana;Hiki ke hoʻokaʻawale ʻia i ke ʻano paʻa kiʻekiʻe a me ke ʻano clamp kiʻekiʻe e like me ke ʻano pili me ka conductor kiʻekiʻe-voltage;E like me ke ʻano o ka pilina ma waena o ka wāwae kila a me ke kumu, hiki ke hoʻokaʻawale ʻia i ka separable (threaded connection) a me ka non separable.
Psn-105 / 5zs nā kaula pili i hana ʻia e kā mākou hui i loaʻa ma M16, M18 a me M20.I ka manawa like, i mea e hoʻomaikaʻi ai i ka mamao creepage, hoʻomohala ʻia nā huahana pollution-resistant psn4-105 / 5zs.
