Nā mea hoʻokaʻawale polimer(i kapa ʻia ʻo composite a i ʻole nonceramic insulators) ʻo iahe aniani aniani

lāʻau i hoʻopili ʻia i ʻelua mau mea hoʻopili metala i uhi ʻia e kahi ʻōnaehana weathershed.Polymer

Ua hoʻokumu mua ʻia nā insulators i nā makahiki 1960 a hoʻokomo ʻia i nā makahiki 1970.

ʻOkoʻa nā insulators polymer, i ʻike ʻia he insulators composite, me nā insulators porcelain

i loko o ia mau mea i haku ʻia me ka polymer rain-proof sheath a me ka mandrel o nā mea resin.ʻo ia

ʻike ʻia e ka maʻalahi ʻole e hōʻiliʻili i ka wai, ke kūpaʻa kiʻekiʻe i ka fouling a me ke kaumaha māmā.Ma ka

i kēia manawa, ʻaʻole ʻo Iapana e hoʻolaha wale i ka hoʻohana ʻana i nā ala kaʻa uila, akā ʻo ka ʻāpana mana hoʻi,

a ua manaʻo ʻia e lilo ia i mea hoʻokaʻawale hou (no ka catenary) i ka wā e hiki mai ana.

Nā noi

Hoʻopili ʻia nā mea hoʻokele o nā laina mana ma luna o ka hale kiaʻi e nā insulators

a me ka lako lako.ʻO nā insulators i hoʻohana ʻia no ka insulation o nā uea a me nā hale kiaʻi ʻaʻole pono e kū wale

ka hana o ka volta hana, akā e kau ʻia i ka hana o ka overvoltage i ka wā o ka hana,

a e halihali pū i ka hana o ka ikaika mechanical, nā hoʻololi wela a me ka mana o ka

a puni, no laila pono ke kūlana maikaʻi o ka insulator.nā waiwai hoʻokaʻawale a me

kekahi ikaika mechanical.ʻO ka maʻamau, hoʻopili ʻia ka ʻili o ka insulator.

ʻO kēia no ka mea: ʻO ka mua, ka mamao leakage (ʻike pū ʻia ʻo ka mamao creepage) o ka insulator

hiki ke hoʻonui ʻia, a hiki i kēlā me kēia kaula nalu ke pāʻani i kahi hana i ka pale ʻana i ke arc;

ʻO ka lua, ʻo ka ua, ʻaʻole e kahe pololei ka wai e kahe ana mai ka insulator

mai ka ʻaoʻao o luna o ka insulator a i ka ʻaoʻao haʻahaʻa, i mea e pale aku ai i ka hoʻokumu ʻana o nā kolamu wai

a hoʻoulu i nā pōʻino pōkole, a pāʻani hoʻi i ka pale ʻana i ke kahe ʻana o ka lepo;

ʻO ke kolu, ʻo ia ka wā e hāʻule ai nā mea haumia i ka lewa ma luna o ka insulator, ma muli o ka like ʻole o ka

insulator, ʻaʻole e pili pono nā mea haumia i ka insulator, kahi e hoʻomaikaʻi ai i ka anti-pollution

ka hiki o ka insulator i kekahi nui.Nui nā ʻano insulators no nā laina mana o luna,

hiki ke hoʻokaʻawale ʻia e like me ke ʻano o ke ʻano, insulating medium, connection method and

ka hiki o ka insulator.
