Construction
Ceramic Strip Heaters are constructed with ceramic insulation that quickly conducts heat from the resistance wire to the sheath resulting in low internal temperatures and long heater life in the most demanding applications. Precise placement of the resistance wire provides uniform sheath temperature across the width and along the entire heated length. This is an extremely rugged construction capable of high temperatures and high watt densities.
The inner construction consists of wound nichrome resistance coil. The inner flexible wire is strung through ceramic insulator pieces. The coils are attached to the screw terminals, or high temperature lead wires, for a positive connection. MgO (magnesium oxide) is used to fill and pack open areas surrounding the coils. The MgO material helps increase the elements thermal conductivity and dielectric strength.
