The high-frequency ceramic tube is chosen as the high-power wire-wound resistor for the production of shunt-connected resistors instead of earthenware tube. The high-frequency ceramic tube has the characteristics of durability, high power, high heat dissipation and small size. Taiwanese nano-silicone coatings are used for surface coating. They are green, environmentally friendly, non-toxic and odorless, and ensure stable power, good heat dissipation and safety. All hardware fittings are thicker, wider and safer to install.
1. It can withstand high current impact, has good power load and wide power range.
2. Fully welded structure, the product has high reliability.
3. Vertical corrugation on the surface is beneficial to heat dissipation and reduce parasitic inductance. High flame retardant coating is selected to effectively protect the resistance wire from oxidation and prolong its service life.

_Resistance in the use of the circuit is best to retain 1.5 times the power margin, such as the circuit voltage 100V, current 0.01A, calculation power: P = 100 * 0.01 = 1W, then resistance can not use 1W, calculation 1 * 1.5 = 1.5W, there is no 1.5W resistance need to use 2W resistance.
_Resistor in use can not exceed the maximum use voltage of resistance, such as resistance 1/4W 10K maximum use voltage is: V = 20.25*10000 = 50V, not 250V in 4.0. Or 1/4W 1M, calculated V = 20.25*1000000 = 500V, the maximum use voltage at this time is 250V in 4.0, rather than the calculated 500V, take the smaller value of the two.
Pay attention to the ambient temperature of brake resistance. If there is no air conditioning, increase the power of using brake resistance appropriately.
