Nā Palena Aluminuma me Cement Resistors pili i ka ia waeʻano o wirewound resistors, akā,ʻaʻohe mea likeʻole ma waena o Aluminum Resistors a me Sima Resistors e pili ana i ka waiwai kū'ē. ʻO nā mea pale sima he mau wirewound resistors i hoʻopaʻa ʻia me ka sima, ʻo ia hoʻi, ua ʻeha ʻia ka uea resistor ma luna o nā ʻāpana seramika non-alkaline wela, ʻo waho o ka mea i hoʻohui ʻia me ka wela-, moisture-, a me ka corrosion-kūpono mea no ka pale a me ka fixation, a ua hoʻokomo ʻia ke kino resistor wirewound i loko o kahi pahu seramika huinahā, i hoʻopiha ʻia a hoʻopaʻa ʻia me kahi sima kūʻokoʻa ʻole wela. ʻO ka ʻaoʻao o waho o ka resistor sima ka mea nui i hana ʻia me ka keramika. ʻElua ʻano o nā mea pale pale sima: nā pale sima maʻamau a me nā mea pale sima talc porcelain.
Mai ka mana o ka mana, ka mana o kapale pale aluminihiki ke hana i ka nui, akā hiki ke hana ʻia ka resistor sima a hiki i 100W. ʻO ka pale pale alumini hale no ka mana kiʻekiʻe o ka resistor, hiki iā ia ke ʻae i ka hele ʻana o nā au nui. Ua like kona kuleana me ka resistor maʻamau, koe wale nō hiki ke hoʻohana ʻia i nā manawa kiʻekiʻe, e like me ke ʻano me ka motika e kaupalena i ka hoʻomaka ʻana o ke kaʻa, ʻaʻole nui ka nui o ke kūʻē. Loaʻa i nā mea pale sima nā hiʻohiʻona o ka liʻiliʻi liʻiliʻi, ke kū'ē haʻalulu, ke kūpaʻa o ka wai, ka wela a me ka wela maikaʻi, ke kumu kūʻai haʻahaʻa, a me nā mea ʻē aʻe. mea lako.
Mai ka manaʻo o ka hana hoʻopau wela, e hana i ka hoʻohālikelike maʻalahi,nā pale pale aluminiua like ia me ka ea ea, a ua like na mea pale sima me na mea paani. Aluminum shell thermal hana maikaʻi, overload hiki i ka manawa hooluolu, i hiki ole i ka mahana kū'ē i kahi kiʻekiʻe loa, i loko o kekahi laula, ke kū'ē waiwai 'aʻole e loli, oiai ka sima resistor cooling e e iki ino. I ka wā o ke kaʻina hana, ua hoʻolako pū ʻia ka resistor hale alumini me nā mea sima kūikawā i loko, ʻo ka ʻokoʻa ʻo ka mea ma waho o ka pūʻolo he alumini alumini, ʻo kekahi ma waho he porcelain.
