Cable / Coil Heaters With Inbuilt Thermocouple And SS Braided Protection Sleeve
1. Coil Heater Brief Introduction
The coil/cable heater can be formed into a variety of shapes. Cable
heaters are small diameter,high-performance units, fully annealed
and readily bent to a multitude of configurations.The cable heater
can be formed into a compact, coiled nozzle heater supplying a full
360 degrees
of heat with optional distributed wattage. A straight cable heater
can snake through an equipment application. Flat spiral
configurations can be used in high-tech manufacturing while a star
wound cable can be used for air and gas heating. Different
applications require different construction methods, including one,
two or four resistance wires; parallel coil or straight wire;
drawn or swaged sheaths; with or without internal thermocouples;
leads exiting from one or both ends, and round, rectangular or
square cable cross sectionals.
