Waya Yakatsetseka yeNichrome Saizi Yakagadzirwa Nekupisa Kwakanyanya Karma Waya Yakatsetseka Yezvinhu Zvinodzivirira Kunyatsonaka
Waya Yakatsetseka yeNichrome Karma Flat WireInoshandiswa Sezvinhu Zvinodzivirira Kururama
1. Karma Alloy
Karma alloy inoumbwa nemhangura, nickel, Aluminium neIron sezvinhu zvikuru. Kudzivirira kwayo kwakapetwa kaviri kusvika katatu kupfuura MENTONG.
Ine tembiricha yakaderera yekudzivirira (TCR), ine EMF yakaderera yekupisa kana ichienzaniswa nemhangura, uye inogara kwenguva refu ichidzivirira.
uye inodzivirira oxidation yakasimba. Tembiricha yayo yekushanda yakafara kupfuura MENTONG (-60~300ºC). Yakakodzera kugadzira zvinhu zvinodzivirira kusimba zvakanaka uye kusimba.
2. Saizi yeKarma
- Waya: 0.018mm-10mm
- Ribhoni: 0.05*0.2mm-2.0*6.0mm
- Chidimbu: 0.5*5.0mm-5.0*250mm
