ZX39 series resistor is suitable for AC 50Hz 1,140V and DC 1,000V, and mainly used for start, braking & timing of motor.

1)In the case that the series of the alloy steel resistors are used for the electrical motor of big capacity,the number of resistor boxes are less than when the resistors made of iron-chrome-aluminum are used.

2)The endurance in vibration,antionxidization,preservation and non-inductance.

3)The connections between the flakes of the alloy steel resistor are by point welding,so there is no contact resistance and its appesrance looks good.

4)The resistance value is stable and the errors of the total values of the whole resistance and every segment are less than ±7.5%.

5)Every box of the standard ZX39 series of resistor contains 20 flakes and is power is 5.6KW while the power of the iron-chrome-aluminum resistor is only 4.6KW.

6)The alloy steel resistor is durable and its service life is very long.

When this resistor works under the bad environment,high temperature,or corrosive surroundings,all its components may be made of alloy steel material,(including the outer panel,protect cover,bolts,screws and so on).

7)The ZX39 series of the alloy resistors have 32 types,which replace the ZX9,ZX12,ZX15 types of iron-chrome-aluminum resistors,and ZX1 and ZX2 types of wire-wound resistors.They contain all kinds of alloy steel resistors,manufactured only by our factory in china.

Note:The alloy steel is one kind of the stainless steel.
