How to install heating cables in different areas
加热电缆是一种现在市面上很常用的采暖、保温环保材料，常用于冬季取暖，房屋融雪等。它虽是一种新型的采暖系统，但是安装起来也不是很难。你知道加热电缆应该怎么安装吗？
严禁蒸汽伴热和电伴热混用于一体，加热带安装时不得破坏绝缘层，应紧贴于被加热体以提高热效率。若被伴热体为非金属体，应用黏胶带增大接触传热面积，以尼龙扎带固定，严禁用金属丝绑扎。法兰处介质易泄漏，缠绕电热带时应避开其正下方。电热带一端接入电源，另一端线芯严禁短接或与导电物质接触并剪切为“V型，必须使用配套的封头严密套封;防水防爆场合应有配套的防爆接线盒和终端子。接线后应用硅橡胶密封（使用屏蔽层的电热带终端处须将屏蔽层剥离250px，以防短路);安装时应逐一测量伴热点的绝缘，屏蔽层必须接地，绝缘阻值小能低于20欧。按电伴热各路的电压、电流等参数选定双极性断电和漏电保护断路器，凡需蒸汽清扫管线除垢时，应注意先清扫后安装电热带，如需每年例行扫线检修应按特殊情况,设计安装。
电伴热系统安装好后，需求在保温层外加警示标签说明“内有电热带”，更需说明所有配件的位置，以便于后期的维修和维护。
MI加热电缆在差别区域安装的留意事项：
MI矿物绝缘铠装加热电缆在管道上安装时普通要求安装在管道的下方，用耐高温铝箔胶带粘贴在管道上，并且边敷设边粘贴，并用力压实使之与管道紧密接触，如果是直径较大管道每隔势必距离要用不锈钢卡带举行固定。
