     The construction of resistor Cement Type Resistors shall be as follows:

 

2.1、External dimensions
            The dimensions shall be satisfied with5、External dimensions
1、General
1.4、Rated voltage
    
The rated voltage shall be the D.C. or A.C.(R.M.S. at power frequency) voltage which corresponds the rated power and the value of which is calculated from the formula below

     E=(PxR)  Where E:Rated voltage(V)   P:Rated power(W)   R: Nominal resistance(Ω)

1.3、Rated power
    
Rated power is maximum power which can be continuously loaded at specified ambient temperature 70,as Table-1;however when the ambient temperature exceeds 70,rated power should be determined from the derating curve of Fig.1.
