Enameled Nichrome /Constantan /Copper / Lizt / Uea waihoʻoluʻu / Kālā / Uea Twist
Hōʻike huahana
Ua hoʻohana nui ʻia kēia mau uea kūʻē enamel no nā resistors maʻamau, kaʻa
nā ʻāpana, nā mea pale wili, a me nā mea ʻē aʻe me ka hoʻohana ʻana i ka hana insulation kūpono loa no kēia mau noi, e lawe pono ana i nā hiʻohiʻona ʻokoʻa o ka uhi enamel.
Eia kekahi, e hoʻokō mākou i ka pale enamel coating insulation o ka uea metala makamae e like me ke kālā a me ka uea platinum ma ke kauoha.E ʻoluʻolu e hoʻohana i kēia production-on-order.
