ORDER TO KNOW:
As the resistor is usually used for the short time work system,and the power and the voltage level are subject to the power distribution system ,users must provide the following parameters when placing the order ,and the visual dimension shall be determined after the consultation between both parties.
1.rated power
2.rated resistance
3.rated current
4.rated voltage
5.power-on time
tection level
7.line incoming and outgoing modes
8.indoor or outdoor type
9.shell color
10.environmental conditions
11.whether with current transformer or other specific requirment
12.whether the preparation of epoxy cast dry-type transformer grounding
