Q:Galvanized flat steel how much is one meter?
Formula of flat steel: width * thickness * 0.00785 (kg/m), zinc coating weight: 1.06Galvanized pipe formula: (outer diameter wall thickness) * wall thickness * 0.02466 * 1.06, DN25 galvanized pipe outer diameter 33.5, GB thickness 3.25, weight: 2.57kg/m, DN32, outer diameter 42.3, wall thickness 3.25, weight: 3.32kg/m. DN stands for nominal caliber.Angle formula (approximate): edge width * thickness * 0.015, 4# angle iron weight 2.422kg/m
Q:Lightning protection grounding, what is called three surface welding?
Lightning protection, grounding, the three sides of the welding:The buried depth of the grounding body shall not be less than 1m at the top, and the steel pipe grounding body shall be vertically configured.The length of the vertical grounding body shall not be less than 2.5m, and the spacing between them shall not be less than 5m.
Q:Do I need to make the ring galvanized flat steel ground connection between the electric well and the distribution room?
There are two forms, one, as you say, because the distribution room has high voltage equipment and cables, and the total equipotential balance is uneven. Repeated earthing of the equipment is required.
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.
Q:How can copper cables and flat steel be welded together?
As a thin strip of copper or copper brazing Hanbian flat, the flat copper or steel crimping brazed or welded to the ground flat strip. Not copper brazing, tin soldered or crimped copper braid, then copper tape terminal is connected to the flat.
Q:What line is the LEB line, please? Is it wire or flat steel or galvanized round bar?
General requirements of the building's outdoor metal doors and windows, equipment shell, distribution box, etc., are required to do a second potential connection,It has not seen the specific technical requirements, we can use the past construction experience, building floor steel ring, Liang Gangjin, reinforced connecting line, equipment shell available 6 mm galvanized welded steel garden.
Q:Why do some buildings need a steel bar around the top?
Galvanized flat steel can be used to produce iron, tools and mechanical parts, and is used as frame structures and escalators for buildings.Flat steel adopts negative deviation rolling, but according to actual weight delivery, the utilization ratio of steel plate increased by -5 percentage points. Flat can according to user needs, set the thickness, width and length of production, for the user to reduce the cut and save processes, reducing labor, material consumption, but also reduce the loss of raw materials processing, time saving, material saving. Products have been specialized in steel structure manufacturing, machinery manufacturing, automotive industry, mining machinery, lifting machinery and other industrial materials.
Q:Is there a requirement for the ground resistance of the field motor? Is it good to use ground flat steel or ground wire?
The enclosure is grounded and the ground wire is the same, and the ground wire requirement is no more than 4 ohms. Generally, the motor shell can be connected to zero. There is no need to ground. In the power system, earthing and zeroing can not be mixed.
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)?
Flat steel and steel, flat steel and angle steel, in order to reliable connection, should be in addition to the contact regions on both sides of the welding, and welding with arc steel should be bent into (or rectangular) clips or directly from the strip itself curved (or rectangular) and steel (or steel) welding.
Q:How to use -40*4 galvanized steel bar to do grounding electrode?
The -40*4 galvanized flat steel is used as the grounding electrode, and the horizontal grounding electrode needs to be welded with the lead wire.
