The invention brings forward a low-thermoelectric-force voltage dividing box capable of generating low voltage. The low-thermoelectric-force voltage dividing box comprises a voltage dividing outer box, a voltage dividing inner box, a heat-insulation layer, a printed circuit board, precision resistors (including a resistor 1 [Omega], a resistor 9 [Omega], a resistor 90 [Omega], a resistor 900 [Omega], a resistor 9 k[Omega], a resistor 90 k[Omega], a resistor 900 k[Omega] and a resistor 9 M[Omega]), and voltage dividing outer box output terminals (with numbers from 1 to 7). The connection mode of the low-thermoelectric-force voltage dividing box is shown as the drawing 1, and the voltage dividing principle is shown as the drawing 2. The low-thermoelectric-force voltage dividing box helps to provide a basis for calibration of low-voltage parameter equipment such as nanovoltmeters in the communication field.
