DWL-P低温自限温电伴热带

发布于:2016-07-25 14:12来源:安邦电伴热带 作者:电伴热带厂家点击:
产品名称:HWLX(RDP2-J3)并联恒功率电伴热带
维持温度:0-150℃
耐温温度:205℃
绝缘材料:氟塑料
产品认证:CE RoHs
主要用途:主要用于各种管道、仪表的防冻保温;最高维持温度可达150℃;
可用于工厂一区、二区爆炸性气体场合。

一、原理
  DWL-P自限温保温电伴热带是利用电伴热设备将电能转化为热能,通过直接或间接的热交换,补充被伴热设备通过保温材料所损失的热量,并采用温度控制,达到跟踪和控制伴热设备内介质的温度,使之维持在一个合理和经济的水平上。
   二、结构
  1、铜芯导线;2、导电塑料层;3、绝缘层;4、屏蔽层;
  三、性能
  DWL-P自限温保温电伴热带金属编制层具有传热和散热功能,可以提高电伴热带的整体抗拉强度,还能作为安全接地线使用,安全接地线必须做到接地保 护,而接地保护是为防止电气装置的金属外壳、配电装置的构架和线路杆塔等带电危及人身和设备安全。适用于干燥无腐蚀的环境和电气上需要接地,以避免静电感 应或产生漏电火花的危险区域。
  四、技术指标
  1、标准颜色:黑色;
  2、温度范围:最高工作温度65±5℃;最高曝露温度85℃;最高承受温度:改良性聚烯烃105℃,阻燃聚烯烃105℃,
  3、施工温度:最低-40℃;
  4、热稳定性:由10℃至99℃间来回循环300次后,伴热带发热量维持在90%以上;
  5、弯曲半径:-20℃时为25.4mm;-30℃时为35.0mm。
  五、电伴热带特点
  1、间歇操作时,升温启动快速;
  2、良好的绝缘性能、抗老化性能、低压运行;
  3、安全可靠、柔软性好、便于安装、使用维护方便等优点;
  4、便于自动化管理;
  5、接地保护,安全可靠。
