恒功率并联式高温电伴热带由多个发热节在整个长度上并联相接,能按实际需要切割长度,发热时必须与温控器配套使用,可精确设定介质温度,实现自动控制。其单位长度的发热量恒定,使用的电伴热带越长,输出的总功率越大。此外电伴热带因富有柔软性,可以紧贴管道表面,外层金属屏蔽网能起到传热和散热的作用,提高电伴热带的整体强度,同时还可以用做安全接地线。所以广泛应用于管道、阀门、小型储罐、泵体等的保温、防冻、加热。

 

并联恒功率电伴热带生产工艺


加强型恒功率电伴热带是在普通型电伴热带外层再包复一层防腐绝缘层,其余结构与普通型电伴热带相同,加强型电伴热带除具有普通型电伴热带的优点外,还具有机械强度高,防腐能力强等特点。 三相恒功率电伴热带除有单相恒功率电伴热带的特点外,同时具有最大使用长度长、发热均匀性好,能均衡电网负荷等特点。
