陶瓷圈

      陶(tao)(tao)瓷電熱(re)(re)圈(quan)采(cai)用(yong)的不是(shi)一般云母撓線方式制作，而是(shi)采(cai)用(yong)陶(tao)(tao)瓷條穿(chuan)絲方式，因(yin)此該產品(pin)的功率比普(pu)通的要高0.5~1.5倍。發熱(re)(re)體為進口圓絲陶(tao)(tao)撓成彈簧狀(zhuang)穿(chuan)入(ru)陶(tao)(tao)瓷條圈(quan)成,外(wai)罩采(cai)用(yong)日(ri)本產不銹鋼,中間采(cai)用(yong)高溫(wen)隔熱(re)(re)保(bao)溫(wen)棉（硅酸鋁(lv)纖維板）防止(zhi)溫(wen)度外(wai)泄。陶(tao)(tao)瓷條是(shi)高頻陶(tao)(tao)瓷具有傳熱(re)(re)快、堅硬不易碎、高溫(wen)不變(bian)形不易老(lao)化等優點。
