石墨烯复合快速接地：

一、石墨烯复合接地极材料：

合德华夏公司产品采用多种金属材料复合制成，表面为石墨烯、铜、铝、钛、硅、钼、铅、锡、等金属渗层，石墨烯是已知的世上最薄、最坚硬的纳米材料，导热系数高达5300w/m.K ( 铜400w/m.K)，常温下其电子迁移率超过20000cm2/n.s (硅1500cm2/n.s )电阻率只有 110-80 .m比铜1.75x10-80 .m更低，为世上电阻率最小的材料，其有良好的摩擦性能，提高复合层的厚度和材料的结合度。The products of our company are made of many kinds of metal composite groundmaterials. The surface is graphene, copper, aluminum, titanium, silicon, molybdenum,Material Science lead, tin and other metal infiltrating layers. Graphene is the thinnest and hardest nanomaterial in the world. Its thermal conductivity is as high as 5300w/m.K (Cu 400w/m.K).Theelectron mobility at room temperature exceeds 20000cm2/n.s (Si 1500cm2/n.s). Resistivityis only 110-8 Q .M, lower than copper (1.75 x 10-8.M), and is the material with the lowest resistivity in the world. It has good tribological properties, which can improve thethickness of composite layer and the binding degree of material.

二、石墨烯复合接地极结构：

采用国内外最先进复合材料烧结法，把多种金属材料烧结在接地材料的表面上，使接地材料结合力更强，实用更加可靠稳定，产品符合国际UL467、国内DLT1312-2013标准。

We use the most advanced composite sintering method at home and abroad to meltstructure a variety of metal materials on the surface of the ground material, so that the bonding strength of the ground material is stronger and more reliable and stable. Products conformto international UL 467 and domestic DLT1312-2013 standards.

三、石墨烯复合接地极降阻：  

垂直接地极通过深度下有湿度降低电阻，效果明显，一年四季无电阻变化。

Resistance  The vertical ground electrode reduces resistance through deep humidity, and the effect isreduction  obvious. There is no resistance change in the whole year.

四、石墨烯复合接地极连接方法：

1个六角六槽的合金钻头和二个芯棒，任意芯棒的接头处于另一根芯棒插孔打击成一体。

1 Six bits and six slots of alloy drill and two mandrel, the joint of one mandrel and anothermethod

mandrel inserted into a whole.

五、石墨烯复合接地极施工：

通过紧配的方式将棒与棒连接，提高了工作效率，不需要复杂大型工具，只需要用轻便的油镐便可以施工安装，5-6人一天可以安装输电线路塔基2座或台变塔杆5个的工作量，只用在打棒处开挖一个200mm x 200mm坑就可以施工，最深可以|打击70米深度，降阻能力十分明显，不用开挖地沟和回填大量土方，大大节省人力物力。

The rods are connected by close matching to improve work efficiency. No needconstruction  for complex and large- scale tools, only with a light oil hammer can built and linstall. 5 people can install 2 tower base or 5 tower poles of transmission line inone day. It can be constructed by digging a 200mm X 200mm pit at the bar. Thedepth can be hit at the depth of 70 meters. The ability to reduce the resistance is|very obvious. It cannot dig a ditch and backfill a large number of earthworks, so itsaves manpower and material resources greatly.

六、石墨烯复合接地极机械寿命：  

机械寿命沿海30年，内地高山丘陵40年。

Coastal: 30 years, the mainland, mountains and hills: 40 years.
