Paglalarawan ng Produkto
Ang PTC Alloy resistance wire ay may medium resistivity at mataas na positive temerature coefficient ng esistance.
Ito ay malawakang ginagamit sa iba't ibang mga heater. Maaari itong awtomatikong kontrolin ang temperatura at sjust power sa pamamagitan ng pagpapanatiling pare-pareho ang kasalukuyang at paglilimita sa kasalukuyang. Kemikal na komposisyon:
