The main factor of the welding effect of copper clad ground rod is the cleanliness of the mold and the object to be welded. If there is dust, grease, oxide (rust) or other attachments on the surface of the welded object,it must be completely removed and made clean and bright before the welding operation, otherwise the conductive and mechanical properties of the welding joint will be seriously affected. However, if the grounding system with copper clad ground rod and bare copper stranded wire cannot effectively solve the problem of excessive contact resistance at the connection point, it cannot meet the requirements.


The exothermic welding method can effectively reduce the contact resistance at the welding point for the connection between the copper steel alloy ground rod and other grounding bodies in the grounding network. In the grounding project of refining and continued construction, the common grounding device is used in the production device. Through the above application examples, it can be proved that the new grounding method and exothermic welding technology can completely replace the traditional grounding method, which has great promotion and application value.

 

After repeated research and demonstration, it is finally decided to adopt a grounding system with copper clad steel as the ground electrode and bare copper stranded wire as the ground wire. The connection between the ground conductor and the ground electrode is made by exothermic welding. This new type of grounding connection mode of the basic operating procedure is very simple, namely the working grounding, protective grounding, lightning protection grounding and anti-static grounding are connected with computers at the same time to form a common grounding network, so the grounding resistance value is required to be less than 1Ω. If conventional galvanized flat steel and angle steel are used for construction, the number of grounding poles must be increased in order to meet the requirements of the grounding resistance.

 

Copper clad grounding rod has a wide range of applications, which can be adapted to the soil conditions of different humidity, temperature and pH value. Quick installation and minimally invasive operation greatly improve the construction efficiency. The exothermic welding mould is designed and manufactured by professionals according to the different connection modes of conductors. In normal use, each mould can be used 50-100 times. The appearance of each connection point is beautiful and consistent.
