Q:What is the difference between 60X6 and 50X4 flat steel in grounding?
There are differences, mainly based on the local geological conditions, the purpose is to meet the requirements of grounding resistance.
Q:What is the negative deviation allowed by the national standard for galvanized flat steel of 40*4?
40*4 galvanized flat steel GB permitted negative deviation value is the thickness deviation value is 0.2mm, the deviation 0.4mm, the width deviation value is the upper deviation 0.5mm, lower deviation 1.0mm
Q:80 * 80 * 4 galvanized flat steel is what specifications?
Galvanized square is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency; or the cold hollow steel well in advance of the re galvanized square by galvanizing processing of pipe.
Q:The grounding electrode 50 angle steel and the ground wire 50, the flat steel lap welding, according to the specification 169 needs the flat steel to be late 90 degrees, bends close to the angle steel side, the overlap width is 4 times (200mm)?
GB50169-2006 in the 3.4.2 stipulates that the grounding body (line) shall be welded by lap welding, and its lap length shall comply with the following requirements:1. flat steel is 2 times its width (and welded with at least 3 edges);2. round steel is 6 times its diameter;3. round steel and flat steel connection, its length is round steel diameter of 6 times;
Q:What about the installation height of the socket and the height of the ground flat steel?
In accordance with the final use of functional considerations, it is not recommended to reduce the socket installation height. According to the actual use of functional requirements, the socket location can be changed to optimize to avoid the ground flat iron position? If it is not feasible, then reduce the height of ground flat iron.
Q:What is the representation of flat steel?
Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings.
Q:Please: hot galvanized flat steel and copper clad steel ground!
Copper layer adhesion is high: because the copper layer and the surface of the steel is the combination of molecules, so the degree of adhesion is high, in the stranding of synthetic strands, the copper layer will not be damaged, there will be no separation, skin cracking and cracking.
Q:What does QB stand for in Q235B flat steel? What's the difference between Q235B and Q235A?
There are also some subtle differences between Q235A and Q235B:1, chemical composition: Q235A:C:0.14~0.22:Mn:0.30~0.65; S:0.050;2, mechanical properties: tensile test without distinction, impact test A do not do, Q235B I-beam, Q235B angle steel, Q235B channel steel, Q235BH steel, Q235B flat steel B do 20 degree impact test, V type impact power (longitudinal) J no less than 27.
Q:Earthing flat steel and earthing main line
Grounding flat ground belongs to the material, the grounding line belongs to the grounding line, grounding flat steel used for grounding grid, the grounding line is also one of the flat ground, for connecting the grounding grid, the grounding grid extends to the metal shell of the substation ground of all electrical equipment, and the grounding grid connected together.
Q:What is the use of slitting flat steel?
Compared with the conventional steel plate, slitting flat steel has the following advantages:1, the product surface is bright and clean. Two times in the process of high-pressure water descaling process, to ensure that the steel surface clean and bright.2, special product specifications. The thickness of 8~45mm, width 150-600mm, length 5-15m, and the product specifications span is dense, can meet the needs of users, instead of in use, without cutting board, we can directly carry out welding.3, both sides of the vertical, clear water chestnut. The two vertical rolling in the finishing mill ensures good verticality of both sides, clear corners and good quality of the edges.
