每小(xiao)時耗(hao)(hao)多(duo)少度(du)電(dian)(dian)(dian)？這(zhe)要(yao)(yao)看(kan)你(ni)用(yong)的(de)(de)(de)伴(ban)熱(re)電(dian)(dian)(dian)纜的(de)(de)(de)功率了，請仔細查看(kan)相關電(dian)(dian)(dian)伴(ban)熱(re)帶(dai)(dai)的(de)(de)(de)產品說明。 例如(ru)(ru)40瓦的(de)(de)(de)恒功率電(dian)(dian)(dian)伴(ban)熱(re)帶(dai)(dai) 每米每小(xiao)時就(jiu)(jiu)是(shi)40瓦時的(de)(de)(de)電(dian)(dian)(dian)耗(hao)(hao)，如(ru)(ru)果一共100米，每小(xiao)時就(jiu)(jiu)是(shi)4千瓦時，也(ye)就(jiu)(jiu)是(shi)4度(du)電(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)耗(hao)(hao)。 但(dan)是(shi)現(xian)在很多(duo)都(dou)是(shi)使(shi)用(yong)自(zi)控(kong)溫電(dian)(dian)(dian)伴(ban)熱(re)帶(dai)(dai)，如(ru)(ru)果是(shi)自(zi)控(kong)溫電(dian)(dian)(dian)伴(ban)熱(re)帶(dai)(dai)的(de)(de)(de)話，實際(ji)功率要(yao)(yao)小(xiao)于標稱功率，因為自(zi)控(kong)溫電(dian)(dian)(dian)伴(ban)熱(re)也(ye)不是(shi)一直(zhi)持(chi)續工(gong)作的(de)(de)(de)，溫度(du)達到一定值后會退(tui)出。溫度(du)降到一定值，又會自(zi)動投(tou)入。自(zi)控(kong)溫電(dian)(dian)(dian)加熱(re)帶(dai)(dai)的(de)(de)(de)話，環(huan)境溫度(du)與維(wei)持(chi)溫度(du)的(de)(de)(de)差數越(yue)(yue)大(da)功率較大(da)，環(huan)境溫度(du)與維(wei)持(chi)溫度(du)的(de)(de)(de)差數越(yue)(yue)小(xiao)功率越(yue)(yue)小(xiao)。
