The selection of lightning protection grounding products can not only look at the unit price, but also to analyze its performance and characteristics. For example, the price of copper-clad steel flat steel is higher than that of galvanized steel, but the current conduction performance and service life of copper-clad steel flat steel are both If the galvanized steel cannot be compared, if the energy and grounding resistance of the drainage are also achieved in a grounding project, because the current conduction performance of the copper-clad steel flat steel is better, the amount of the steel is less than that of the galvanized steel. The cost of copper-clad steel flat steel and galvanized steel in a project is probably not much different. In the long run, galvanized steel is not as good as copper-clad steel flat steel. Copper-clad steel flat steel has a service life of more than 50 years, while galvanized steel has a service life of about 20 years, using copper-clad steel flat steel. Not only can the grounding system be less modified, but also the cost of the project can be saved. From this point of view, the copper-clad steel flat steel is much better than the galvanized steel.
The XYT series of resistance reduction module is a new type of low-resistance resistance-reducing material developed by researchers of Botou Xinyongtai Lightning Protection Equipment Co., Ltd. after careful research. After the XYT series of resistance-reducing modules are buried in the earth, the non-metallic materials and the earth form a good contact. On the one hand, it can be in close contact with the soil, expand the area of ​​the flow, and reduce the electrical resistivity of contact with the soil; on the Other hand, the resistance-reducing module can flow into the surrounding soil gap, significantly reducing the electrical resistivity of contact with the soil, A low-resistance region with a gentle change in resistivity is formed around the grounding body, so that the grounding resistance of the entire grounding system is significantly reduced. Because the XYT series of resistance-reducing modules have strong moisturizing, hygroscopicity and stable electrical conductivity, the contact resistance of the metal grounding body through the peripheral non-metallic module material and the earth will be greatly reduced, achieving good resistance reduction. Because the XYT series of resistance reducing module contains metal passivation preservative, it can quickly passivate the surface of the metal grounding body, effectively prevent the corrosion of the metal grounding body and prolong the service life of the metal grounding body; the humectant can effectively be used in the XYT series of resistance reducing module Keep the moisture in the soil and prevent the grounding resistance in the dry season from being affected by climate change, because it has better corrosion resistance and long-term stability than the XYT series of resistance reducing modules.
Applicable conditions for the resistance reduction module:
The soil resistivity directly affects the installation method of the grounding system and the amount of the module. It is necessary to measure and consult the relevant data first. If the soil resistivity is very high (eg rock formations, sandstone), consider increasing the amount of synergist (reducing agent).
Humidity and temperature: The humidity and temperature of the soil directly affect the value of the grounding resistance. The resistance reduction module should be buried as much as possible below the groundwater level and the frozen soil.
Botou Xinyongtai exothermic welding mold is mainly used in hot-melt welding. The main material of the exothermic welding mold produced by Xin Yongtai Lightning Protection Equipment Co., Ltd. is very high temperature resistant (maximum temperature can withstand 3500oC), as well as high temperature adhesives and antioxidants. At normal temperature, the exothermic welding mold is high pressure. The 100T hydraulic series is adopted, and the surface is smooth and flat, which can perform hot-melt welding of most metals. At the same time, due to the high pressure forming, the exothermic welding mold has high strength and is not easy to be broken. The anti-fall height is more than 2 meters, which avoids the disadvantages of other brands using pure graphite materials, easy to break and short service life.
Xin Yongtai Technology Hot Melt Mold Features
1. The raw material is high temperature resistant and anti-oxidation material, non-toxic and non-polluting.
2. The exothermic welding mold adopts 100T hydraulic forming, the strength is super high, and it can resist the vertical drop test of more than 2 meters.
3. The exothermic welding mold has reasonable structure, good sealing performance, and the product is smooth and smooth after welding.
4. The exothermic welding mold has a long service life and can be repeatedly made more than 70 times, which is more than double the life of ordinary products.
