1、 Product Introduction

Graphite grounding body is a new type of non-metallic conductive material with stable performance, low self resistivity, high and low temperature resistance, acid and alkali corrosion resistance, high current impact resistance, and unchanged material properties. Especially when transportation is inconvenient. In mountainous areas without electricity and with high soil resistivity, graphite grounding can better meet design requirements, and is easy to construct, reducing excavation and costs. Therefore, its application in power transmission and transformation lines is becoming increasingly widespread.

2、 Performance characteristics

This grounding body is cable shaped and made of high carbon graphite wire. The connection end to the tower is made of stainless alloy, which is a non-metallic conductive material. It is corrosion-resistant, rust free, has stable grounding resistance, does not counterattack under high current impact, is not damaged, has constant resistance, is resistant to high and low temperatures, has a long service life of 30 years, is maintenance free, safe and reliable. It is not limited by environmental or climatic conditions, easy to install, does not require electrical welding, saves labor and time, saves materials and costs, is energy-saving, environmentally friendly, and anti-theft. It is especially suitable for use in acidic and alkaline soils, swamps, humid and hot areas, and beaches.
