Copper grounding rod manufacturers wholesale steel core, copper steel ground rods - Preferred Ningbo speed up - Copper Clad Steel grounding rods grounding rods copper grounding rods copper ground rod Applications: petrochemical, oil storage facilities, power plants, substations, communication base stations, airports, and other places of the network room Lightning Protection Engineering. Copper Ground Rod Manufacturer: Ningbo times Sudagongsi production Copper grounding rods is to use the amount of ninety-nine percent of the copper molecules uniform coverage to the low-carbon steel core, copper and steel core complete molecule . It has a copper layer thickness (0.25 mm), the adhesion is good, do not peel (can be rolled thread) and so on. The advantage is that tensile strength (up to 600 N / mm2), corrosion resistance (guaranteed service life of 50 years). Copper grounding rods, after deep underground whether natural corrosion or electrochemical reaction, there is a strong protection. Ground rods and grounding cable using chemical welding flux, so that the ground is under the copper device is fully protected, it becomes virtually maintenance-free grounding devices. Copper grounding rods with a coaxial connector, combating head and drill bits and other accessories. You can also use the tip end of the copper grounding rods. Ground Rod features: 1. tensile strength (up to 600 N / mm2) 2. corrosion resistance, can ensure that more than 50 years of life 3. Copper grounding rods compared with copper grounding rods, both copper excellent electrical properties, but also save the cost of grounding rods and grounding cable using hot-melt welding flux, so that the ground is under the copper device is fully protected, it becomes virtually maintenance-free grounding devices. Common product specification is complete, according to customer requirements.
