Features / benefits
1.revolutionary changes in grounding material.
2.fast-track construction &convenient construction.no welding.
3.convenient transportation,not easy broken.
4.long life and difficulty to corrosion.durable
5.safety and environmental protection.
6.good economic benefit with low cost.
Application
Transmission line tower. power plants, substations, gas stations, communications, defense, railways and refineries, construction and other important equipment grounding system. ( especially solve the soil resistivity where the terrain is limited for excavation area.eg: town,residential area,hillside,mountaintop)
