<p>Flexible heating plate is manufactured round a grid of insulated resistance wire with fibre glass matting over the wire grid and a flexible silicone elastomer covering the assembly. An electric power cable is connected to the ends of the electric resistance wire. The electric resistance wire is corrugated along its length and is wound in a zig-zag grid using two rows of pins on a table surface as a former. Layers of fibreglass matting are placed over the resistance wire grid then the assembly is removed from the former, and a second fibreglass layer placed on the other side of the resistance wire grid. The assembly is then immersed in a silicone elastomer compound, after the power cable has been connected, forming a sealed outer envelope over the assembly.</p> |
