Nichrome thread up to 2 mm is usually used for heating eelementov electrothermal increased equipment reliability, as the heat-resistant and chemical-resistant alloy for neprezitsionnyh resistors that can operate in hostile environments. Because of its properties, it has a high operating temperature of approximately 1100 ° C, mechanical strength. Also — this is a mandatory requirement for such materials — high resistivity.
selection
Nichrome wire is an integral part of the heating parts of vacuum devices and connectors of electronic equipment. To operate at a voltage of 220 volts, it is subject to the overall diameter of the selection rule. You must select a wire, the allowable current strength which is not less than the estimated strength of the current passing through the heater.
Calculation
Using simple arithmetic proportion is easy to calculate the length of nichrome filament under different voltage. Assume, determine the thread length on the winding shaft 3 mm. The recommended length of this thread to be equal to 380 Volt 16 cm is the proportion:. 380 Volt — 16 cm, and 220 Volts — X cm
Then X = 220 multiplied by 16 and divided by 380, we get 9 cm.
Nichrome filament wound Cr20Ni80 9 cm on the rod without undercutting, connect it to the voltage to ensure proper winding.
Marking
Marking Nichrome wire reflects the percentage of cells in this case — Cr20Ni80 is 20% chromium and 80% nickel. By default, the alloy introduce additional components such as silicon, manganese, aluminum.
