ʻO ka pahu kaʻa kaʻa maʻalahi, i kapa ʻia hoʻi ʻo ka hui hoʻonui ʻana o ka pahi kaʻa, ka mea hoʻopili hoʻonui ʻia kaʻa pahi, e komo pū ana ka pahu kaʻa paʻa keleawe foil, ka pahu kaʻa paʻa keleawe, ka busbar flexible copper braid a me ka busbar uea keleawe flexible busbar. He ʻano ʻāpana hoʻopili maʻalahi i hoʻohana ʻia e uku no ka deformation bar bus a me ka deformation vibration ma muli o nā loli wela. Hoʻohana ʻia ia i loko o ka pā pākaukau a i ʻole ka hoʻopili uila ma waena o nā pahu kaʻa laminated.
