1. Adopted high quality importe stainless steel or domestic stainless steel electric heating metal material, the product operates safely and reliably with the advantages of high conductivity, high temperature coefficient, corrosion resistance, thermostability, good oxidation resistance, high tensile strength, resistance value stability and etc.
2. The device also could be applied in medium power distribution system. When transfomer is angle-connected, independent grounding transformer could be installed with which the neutral point and resistance are connected
3. Resistance value could be designed from 1ohm to 2000ohm and current from 1A to 2000A
4. The cabinet could be installed indoor or outdoor. As the cabinet body is corrosion-resistant and of high protection grade, made from stainless steel plate or painted cold rolled steel plate
5. The counting function could be added to the device, which records times of resistance grounding
6. Isolated switch could be added which convenient examination and repair and so does temp. Or humidity controller
7. Intelligent monitor is at customers' option, which could monitor un-balanced current of neutral point when resistance cabinet is in normal operation, temp. Of resistance panel, and
