    Can design different kinds of resistors basing on the user requirements,resistance is from 1Ωto 2000Ω,the flowing current ia allowed from Ω~2000Ω,and the flowing time is 10s,15s,30s,60s,2h.

   Service Condition:

    1.Generally applies to outdoors,used in the system of 50 Hz and 60 Hz.

    2.The altitude shall not exceed 3500m.

    3.Ambient temperature : -20°C~+70°C,Relative humidity:≤95%

    4.Wind pressure is not above 700Mpa (amount to wind velocity 34m/s)

    5.Earthquake intensity :< 8

    6.Thickness of ice coating: <10mm

    7.Gradation for surface pollution of air : not above class 4

    8.The air at the installation site shall be free from flammable gas, explosive gas,corrosive 

       gas,and conductive dust.

    9.As resistor is heating element,when use it ,the temperature will rise highly,so the installation    of resistors should be in the place around with gap,to prevent the outside heat source.please attation,when installing and using.
