"The Copper Bonded Earth Rod is built from high-quality, long-lasting components. We are the leading producer, supplier, and distributor of solid copper bonded earthing rods with copper bonding. These rods have a low electrical resistance, allowing currents to be dissipated. These things are available to our clients at the most reasonable prices. You may order this item by contacting us
Supplier: Gi perforated cable tray, gi earthing electrodes, copper bonded earthing, copper plates, copper wires, gi earthing strips
Bonding jumpers shall consist of 100 mm (4 inches) wide copper strip or two 6 mm² (10 AWG) copper conductors spaced minimum 100 mm (4 inches) apart. Use 16 mm² (6 AWG) copper where exposed and subject to damage. B. Comply with the following when shielded cable is used for data circuits.
The electrodes have a covering of electrolytic copper with a width of 254¥ìm and purity 99.9% which allows a proven resistance to corrosion. This type of electrolytic covering does not produce cracks or fissures, which are produced in the exterior layer of the copper clad rods, worsening its resistance to corrosion. Using the adequate accessories, threaded Copper bond earth rods allow the extension of the rod to get better earthing resistances. Specifications Copper Earth rod: 1.copper coated steel ground rod , molecularly bonded into steel core 2.Steel core: Low carton high tensile steel 3. 99.9% pure electrolytic copper 4:meet UL467 Technical parameters: (1):Copper layer thickness : ¡Ã0.254mm (2):Resistivity : ¡Â 0.05¥Ømm (3):Tensile strength : 500-580N/mm©÷ (4):Copper earth rods be bent over120 ¡Æ, no crack peeling or sharp (5)Corrosion resistance: working life more than 30 years, relieve the maintenance cost of earth rod.
