Q:Is the laying of a 40X4 flat steel for fire fighting metal trunking?
The angle between the bridge is connected or welded together by rivets, but in accordance with the relevant provisions of the State Grid, not admit that these are valid connection. At the same time in order to protect the ground, must have a grounding cable connection between all seams of metal objects, so that it can recognize all of its bridge is connected to one end, through one or a plurality of total grounding grounding.
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:Where can I buy ground level bending machine?
Galvanized flat steel and galvanized steel (or steel) for welding, reliable connection, should be in addition to the contact regions on both sides of the weld, should also direct the flat curved (or rectangular) and steel (or steel) and steel pipe welding, when welding on the steel pipe wrapped around the welding length 2 times less than the width of flat steel.
Q:What is the negative deviation allowed by the national standard for galvanized flat steel of 40*4?
40 is the width of the section steel, 4 is the thickness of the steel, and the unit is mm.Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling.
Q:Construction of lightning protection ground galvanized flat steel approach, need to retest test? What's the test?
Hot rolled flat steel is a general purpose rectangular cross section strip. Its specifications are expressed in millimeters of thickness / width, flat steel can be finished steel, used for components, ladders, bridges and fences, etc.. Flat steel can also be used to weld rigid steel and billets and slabs of laminated sheets. This standard is applicable to hot-rolled flat steel with rectangular cross section. Measurement: flat length and length of flat steel, according to the theoretical weight of delivery.
Q:-40x4 hot galvanized flat steel, a water 1m, what do you mean?
Water is to protect the wall foundation using cement mortar width not less than 600 of a circle along the walls of the cement ground, if the main part of the project before the electrical engineering, auxiliary grounding length less than in bulk water, auxiliary grounding, ditching to destroy the water, so that the design requirements of 1 meters water is conducive to the construction of welding, may be more than one meter in order to facilitate their work.
Q:What is the difference between steel band and steel ring? The steel strip is flat steel and the steel ring is made of steel. Am I right?
A steel strip is also a coil, usually a narrow strip, also known as a steel strip. The volume is relatively wide. In addition, flat steel is usually hot-rolled out of long strip steel, fixed length 5 and 5.5,6 meters range, steel coil is Kaiping Chang 12501500, length 2.5 meters, 4 meters, 6 meters, ranging from steel plate
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:Is medium plate steel flat?
Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of 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:Does the cable trench need grounding?
According to the design requirements of excavation and masonry, the groove side wall welding force angle, steel frame and required to ground, covered with the cover of the underground channel, that is, cable ditch. Its purpose is to lay underground tunnels for cables.
