HCL串联式恒功率电伴热带

信息来源:皖缆集团 浏览次数:2873 发布时间:2014-03-04

HCL型串联式恒功率电伴热带是一种新型的电伴热产品,它与其它电伴热带相比,其最大特点是使用长度长,它比一般恒功率、自限温电伴热带的最大使用长度长5—12倍。因此特别适用于石油、化工、电力、码头等行业的长输管线,大型槽池,油罐等防冻,保温及伴热,与其它防爆附件配合后,可用于Ⅱ类防爆炸性气体场合。
工作原理:根据焦耳定律可知,电流通电导体不断的放出能量,形成一条连续的、发热均匀的电伴热带

二、型号规格
HCL1,2,3(Q)-J3-1.5:芯线结构19×0.32/φ1.60,公称截面1.5,20℃阻值12.70Ω/km;
HCL1,2,3(Q)-J3-2.0:芯线结构19×0.37/φ1.85,公称截面2.0,20℃阻值9.50Ω/km;
HCL1,2,3(Q)-J3-2.5:芯线结构19×0.42/φ2.10,公称截面2.5,20℃阻值7.43Ω/km;
HCL1,2,3(Q)-J3-3.0:芯线结构19×0.42/φ2.25,公称截面3,20℃阻值6.53Ω/km;
HCL1,2,3(Q)-J3-4.0:芯线结构19×0.42/φ2.60,公称截面4,20℃阻值4.88Ω/km;


三、结构形式
1、A型结构为有三根独立的相同功率,相同长度电伴热带联合组成;
2、B型结构为三根互相绝缘并联组合在一起的电伴热带;
3、HCL型串联型电伴热的绝缘护套及外缘护套均为F46或F4,发热芯为特种发热器材,加强铜编织外护套内绝缘护套发热芯。编织层可选:“合金丝”和“镀锡铜丝”,材质不同价格不同。
 

四、安装说明
(1)施放电伴热带时不应在地面拖拉;
(2)电伴热带安装时碰到锐利的边棱时必须把锐角磨光或用铝胶带衬垫,以防绝缘层划破;
(3)电伴热带弯曲安装时其最小弯曲半径不应小于其厚度的五倍;
(4)电伴热带安装时用铝胶带粘贴,一则增大散热面,有利于热传导,二则方面安装。敷设后,每隔50—80cm用固定胶带径向固定;
(5)串联式电伴热带一般均按管线实际长度设计,因此安装时应严格设计长度安装,过长或过短影响功率,因此不允许任意剪切;
(6)串联式电伴热带安装时按Y接线,为避免三相电流误差,故在末端需接地;
(7)电伴热带控制柜应有过载、短路、漏电保护及温度控制装置,以保证使用质量;
(8)电伴热带埋地或周围有腐蚀性气体则应使用加强型。


五、技术参数
三相串联恒功率电伴热带主要用于各种管道、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。
额定电压:380VAC
介电强度:2000VAC/50HZ/1min
长期最高耐温:最高表面温度195℃
