Abstract

The invention provides an ion grounding electrode filling material which is characterized by comprising the following raw materials in percentages by weight: 55% of graphite, 20% of bentonite, 5% of conductive powder, 3% of lime and 17% of alum. The ion grounding electrode filling material has good resistance reducing effect, low resistance and longer service time and better stability.

Description

technical field [0001] The invention relates to a ground material, in particular to an ion ground electrode filling material. Background technique [0002] With the continuous development of the national economy and the rapid improvement of the modernization level, under the guidance of informatization to drive industrialization, various types of information equipment, electronic computers, precision instruments, and data network equipment are more and more widely used, and the hazards of lightning strikes are also increasing. getting bigger. In this case, it has become a mainstream to use lightning and surge protectors to discharge the lightning current into the ground, and grounding materials are also widely used in various grounding systems. The quality of the grounding effect is directly related to Therefore, grounding has become an important part of lightning protection. In urban construction, the utilization rate of land area is increased, and the open space between ...
