Basic Knowledge And Tensile Test Of Copper Clad Ground Rod
1. Definition of 1 2 in x 8 ft copper ground rod
10 foot copper ground rod is a steel product composed of multiple steel wires twisted together. The surface of carbon steel can be added with galvanized layer, zinc-aluminum alloy layer, aluminum layer, copper layer, epoxy resin coating, etc. as needed.
2. Classification of 5 8 by 8 copper clad ground rods
According to the use classification: prestressed steel strand, (electricity) galvanized steel strand and stainless steel strand, among which prestressed steel strand coated with anti-corrosion grease or paraffin and wrapped with HDPE is called unbonded prestressed steel strand, and prestressed steel strand is also made of galvanized or galvanized aluminum alloy steel wire. Classification according to material properties: steel strand, aluminum-clad steel strand and stainless steel strand. According to the structure classification: prestressed steel strand can be divided into 7-wire, 2-wire, 3-wire and 19-wire according to the number of steel wires, and the 7-wire structure is commonly used. Galvanized steel strand and aluminum-clad steel strand for power are also divided into 2, 3, 7, 19, 37 and other structures according to the number of steel wires, and the 7-wire structure is commonly used. Classification by surface coating: can be divided into (smooth) steel strand, galvanized steel strand, epoxy coated steel strand, aluminum clad steel strand, copper coated steel strand, plastic coated steel strand, etc.
3. Application of 5 8 in x 10 ft copper ground rod
5 8 in x 8 ft copper ground rod usually refers to the use of load-bearing cables, pull wires, reinforcing cores, etc., and can also be used as ground wires for overhead power transmission, blocking cables on both sides of the road, or structural cables in building structures. The commonly used 5 8 x 8 copper ground rod in bonded rod is low relaxation copper bonded without coating, and there are also galvanized ones, which are often used in bridges, buildings, water conservancy, energy and geotechnical engineering, etc. copper bonded earth rod price is often used in floor slabs, foundation engineering, etc.
4. Detection of steel strand
Steel strand and its connectors are an indispensable material for construction projects. The detection of steel strand and its connectors is directly related to the quality and safety of construction projects. Therefore, it is very necessary to detect steel strands.
The test items for steel strands include tensile test, overall dimensions, steel strand straightness, relaxation rate, elastic modulus, etc.
