| 1.The Numbered And Are Explained In The Corresponding Sections |
|
|
Three parallel insulation copper wires form power generatrix. Electric heating threads are wound around the inner jacket insulation layer ln every certain distance, the heating thread is welded in turn to the three power generatrix circularly. This makes every 2 phases into acontinuous parallel connection resistance. When the generatrix is connected to 3 -phase power supply, the every parallel resistance heats at the same time This makes a continuous heating belt. |
