一、概述
    D/Z/GWL-CT自控温电伴热带自限温电伴热带)分为三种,DWL-CT为低温系列自控温电伴热带,ZWL-CT为中温系列自控温电伴热带,GWL-CT为高系列自控温电伴热带;CT为防腐加强型,外护套使用PF46或PFA进口原料。

    D/Z/GWL-CT自控温电伴热带(自限温电伴热带)结构由导电聚合物发热芯体内的两根平行导线组成,发热芯体经过辐射交联工艺确保经久耐用,可自动调节输出功率来补偿温度变化,当电流经过导体之间的导电聚合物核心便会产生热能。
    镀锡铜丝的编织层覆盖率达到85%,能够更好的起到防爆和抗外力的作用,屏蔽效果更佳。外护套采用了PF46、PFA进口原料生产,大大提高了防腐防爆性能,可耐温180℃以上。是真正可以媲美进口电伴热带的产品,适用于有特殊要求的危险场所,也同样适用于家庭住宅、大型建筑以及工业应用领域。
