GEM Resistance Reducing Material JSBOUND JB-DA
Products Descriptions
Jsbound's Resistance reducing material is a simple, economical and easy-to-use conductive backfill material which can substantially lowers the resistance and surge impedance
of the grounding system, especially in areas of poor conductivity such as rocky ground,areas of moisture
variation and sandy soils.
Features
1. Permanent and maintenance-free
2. Maintains its earth resistance with time
3. Harm-free to the soil and local water table
4. Easy installation-installed in the slurry form
5. Requires no continuous presence of water to maintain its conductivity
Applications
The products can be applied widely including various fields in national economy, such as power,
communication, construction, television, railway, road, military, mine and so on.
