1. Structural Features

　　o Modular designThe single heating element is composed of six and a half resistive wires (such as Cr20Ni80 nickel-chromium alloy) in series, with a total power of 7.92kW, compatible with standard radiation tube length and furnace chamber space.

　　o Tight layoutThe resistance wire is wound into a spiral, filled with high-purity oxide insulation to ensure insulation and structural integrity at high temperatures.
