What is the difference between a constant power electric heating belt and a self limiting temperatur
恒功率电热带和自限温电热带有什么区别
这两者功能相似,很多用户在购买时经常混淆它们。根据不同的适用场合和使用要求,选择不同的电热带,但在不同场所的使用中,选型时仍应注意恒功率电热带和自限温电热带的区别:
一、结构区别
恒功率电热带:在绝缘导线上缠绕镍铬发热丝,隔一定距离与绝缘导线相连接。
自限温电热带:在导线中间填充PTC高分子导电材料;
二、工作原理
恒功率电热带:绝缘导线上通电时,电流通过发热丝,发热丝发热,传递热量。
自限温电热带:接通电源后,电流由其中一根导线通电,经过PTC芯带到另一根导线,形成回路,具有电阻值的芯带发热;
三、运行环境
恒功率电热带:在石油、化工、钢铁等需抗凝场所有明显优势。
自限温电热带:多运用于地热采暖、消防、解冻、石油化工保温;
四、使用长度
恒功率电热带:最大使用长度180m,最短使用长度不小于5m。
自限温电热带:最大使用长度100m,最短使用长度10mm;
五、产生效果
恒功率电热带:始终保持一定的温度,发热量及功率恒定,稳定性强。
自限温电热带:能随周围环境温度调整自身发热温度;
六、其他
恒功率电热带:可根据使用情况发热节长任意剪接。
自限温电热带:不可任意剪接;
