        (1)產品結構與工作原理

        Product Structure and Working Principle



           電源母線為二根平行絕緣銅線,在內絕緣層上纏繞電熱絲,并將電熱絲每隔一定距離與母線連接,形成連續(xù)并聯電阻。母線通電后,各并聯電阻發(fā)熱,因而形成一條連續(xù)的加熱帶。

        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)產品特點及應用場合

          Product Characteristics and Applications


            恒功率電熱帶單位長度的發(fā)熱量恒定,使用的電熱帶越長,輸出的功率越大。該電熱帶在現場能按實際需要長度任意剪切,并具有柔軟性,可以緊貼管道表面敷設。電熱帶外層的編織層能起到傳熱和散熱的作用,提高電熱帶的整體強度,同時還能用作安全接地線。

        The heat output per length unit out of the constant wattage heating cable is fixed and constant.The longer the heating cable, the stronger the power is output. The electric heating belt can be cut flexibly according to the actual needs. And it is flexible and can be laid closely on the pipe surface. The outer brade layer can execute the function of heat transmitting and radiating, to enhance the general intensity of the heating belt. It can also be earthed.


            一般用于小管線或管網系統(tǒng)短管線的伴熱保溫。

        Itiscommonly used for thermal insulation of the small pipes or the short pipes of the pipe
