JFB-口/2 型单相恒功率并联电热带
1)产品结构与工作道理
Product Structure and Working Principle
电源母线为二根平行绝缘铜线，在内绝缘层上缠绕电热丝，并将电热丝每隔肯定距离与母线衔接，形成陆续并联电阻。母线通电后，各并联电阻发热，因而形成一条陆续的加热带。
The power generatrix wire is 2 parallel insulative copper wires. Heating threads are wound around the inner jacket insulation layer. Every certain distance the heating thread is welded to the generatrix,which makes the continuous parallel connection resistance. When the generatrix is powered, the parallel connection resistance begin to heat. This makes a continuousheating belt.

3)产品特点及利用场所
Product Characteristics and Applications
恒功率电热带单元长度的发热量恒定，使用的电热带越长，输出的功率越大。该电热带在现场能按现实必要长度肆意剪切，并拥有柔软性，能够紧贴管路表表敷设。电热带表层的编织层能起到传热和散热的作用，提高电热带的整体强度，同时还能用作安全接地线。
