影响电伴热带质量的因素也是购买评判的标准

随着伴热带的市场越来越大,各地的厂家纷纷投入生产,但由于生产设备、技术水平、工艺条件的限制,产品质量也参差不齐。如果用户不慎使用了劣质的电伴热带,轻则短路跳闸,重则会引发伴热管线起火,甚至烧毁被伴热设备等重要部件这都是不可挽回的损失。

优质电伴热带

如何鉴别电伴热带的品质,成了选购电伴热带的头等大事。我们可以从以下几方面对电伴热带的品质进行区分和判断:电伴热带是扁形长带,其导电线优劣也直接关系到产品的好坏,通常导电线芯用镀锡或镀镍铜丝绞合成型,制造时除了要选择质量好的镀锡铜丝外,还必须考虑导电线芯表面护套对电伴热带产生的影响。

电伴热带中的PTC芯带是电伴热带的核心部分,芯带的好坏决定了电伴热带在使用中的稳定性及使用寿命,其关键系数就是启动电流大小,启动电流是指电伴热带接通电源时,瞬间产生的最大电流的值。它对电伴热带的品质有着决定性意义,如果启动电流较大,那么单一电源的电伴热带使用长度就会减短,这样每次启动时,还会破坏PTC层与导电线芯的电接触界面,缩短电伴热带的使用寿命,并存在很大的安全隐患。所以在选购时,务必弄清启动电流这个参数,在条件允许的情况下,最好自己测量,尽量选购启动电流较小的产品,以免造成不必要的损失。
