Mai ka makahiki 1958, ua ʻoi aku ka nui o ke kūʻai aku ʻana o Thunder, Lightning brand tempered glass insulator ma mua o 100 miliona mau ʻāpana, helu no ka hapalua o ka ʻāina a me ka hapaono o ka honua.
Hoʻokumu ʻia ka Glass Insulator me kahi pāpale hao, nā ʻāpana aniani i hoʻopaʻa ʻia a me ka pine kila, i hui pū ʻia me ka lāʻau sima.Ma mua o ka hui ʻana, ua hāʻawi ʻia ka piko o ka pine kila me kahi kīʻaha palupalu, ʻo ka lua o loko o ka pāpale hao a me ka pau ʻana o ka pine i ka wahi hoʻopili me ka mea hoʻopili sima ua uhi ʻia me ka tar.Hoʻohana ʻia ka gasket a me ka tar no ka hoʻopōʻino ʻana i ka wā e kū ana ka insulator i ka hoʻonui ʻana a me ka ʻoki ʻana.Hoʻohana ʻia nā ʻāpana aniani i hoʻopaʻa ʻia no ka insulate.
Loaʻa i nā Insulators aniani nā hiʻohiʻona o ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka haki ʻana i ka waiwai ʻole, a me ka ʻike maʻalahi;ikaika mechanical kiʻekiʻe;kū'ē maikaʻi arc;maikaʻi ka hoʻomaʻemaʻe ponoʻī a ʻaʻole maʻalahi ka makahiki.Eia kekahi, ʻo ka mea hoʻoheheʻe i nā mea maikaʻi o ka hydrophobicity ikaika, ke kūpaʻa lōʻihi i ka pollution, ka leakage haʻahaʻa ma ka ʻili, a me ka mālama ʻole i ka wā o ka hana;hoʻohana nui ʻia ia i nā kaʻapuni like ʻole ma ka home a ma waho.
Hoʻokaʻawale ʻia nā insulators aniani hoʻokuʻu disk i ke ʻano maʻamau, Anti-pollution Type, DC type, Aerodynamic Type, Out-ribs Type a me Ground Wire Type.
