Application of electric heat tracing in household life

北方地区冬季气温较低，生活水管容易结冰，影响正常生活供水。人们会采取热水灌注解冻的方法，但这种方法可能会导致管道破裂。因此，建议采用伴热带的方式保持生活管道畅通。
管道防冻的目的是补充管道内外温差造成的热量损失和管道内液体损失的热量，从而平衡管道内流动液体的温度。生活管道中的介质为水，因此只需将温度维持在5℃左右，即可保持管道畅通。因此，自限温伴热带的选择可以满足要求。它由两个并联母线和聚合物导电碳颗粒加绝缘层组成。PTC加热元件的电阻率具有高的正温度系数，并且并联连接。其特点决定了它可以任意切割、横切、卷绕良好，并具有自动温度控制功能，非常方便。
以上介绍了电伴热带在国内管道防冻中的应用。电伴热带不仅用于国内管道防冻，还广泛应用于石油、化工、电力、冶金、食品等管道保温领域。芜湖市恒鑫电缆有限责任公司是专门生产电热带的厂家，我们的产品广泛应用在生活和生产中，有需要的可以联系我们。
