Product Introduction<\/strong>
\nThe main component of the absorptive grounding electrode is conductive non-metallic material. Internally, it contains a cable-like graphene lightning protection grounding body. The overall shape is cylindrical, unaffected by water, soil, acidity, alkali, or galvanic corrosion. Its main component is high-carbon graphene, which has stable chemical properties. It is connected to the graphene lightning protection grounding body using a special 316 stainless steel connecting clamp (lap clamp).
\nAbsorptive grounding electrode specifications: \u2264100*1000mm. Measured values \u200b\u200bmust not be less than nominal values.
\nThe resistance change rate of the absorptive grounding electrode after a 100kA impulse current withstand test is \u22645%. The resistance change rate of the absorptive grounding electrode after a 30A power frequency current withstand test is \u22645%.
\nThe solid-state resistivity of the absorptive grounding electrode is \u22644\u00d710-5 \u2264 183 \u00b5m.
\nWeight per unit length of the absorptive grounding electrode: 10\uff5e11 kg.<\/p>\n

(Note: Each set of equipment is equipped with one wire lug, a 15-meter graphene grounding electrode, two grounding electrodes, and two sets of connecting clamps. Among them: 1. The wire lug is made of 316 stainless steel; 2. The armored protection includes a 2-meter braided 316 stainless steel protective layer and an outer insulating sheath to enhance its resistance to external damage; 3. The clamps are made of 316 stainless steel to enhance corrosion resistance.)<\/p>\n
