Q:How large is the flat steel used for equipotential grounding?
3.2.15 general equipotential connection with the sectional area of protective bonding conductors, shall not be less than the maximum protection of conductor size distribution line 1/2, protective bonding conductor cross-sectional area of the minimum and maximum value shall comply with the provisions of table 3.2.15.
Q:The difference between galvanized flat steel 40*4 and galvanized flat steel 80*8 is the difference on the material list!
There are many kinds of flat steel, Q235A/B/C, mainly depends on the location of your specific requirements, what is needed?;
Q:Difference between cold drawn flat steel and flat steel
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:What is flat steel, please? What are the specifications 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.
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:Earthing flat steel and earthing main line
The flat steel is connected to the ground system, and the grounded line is connected to the protected equipment
Q:Can roof strip be replaced with steel pipe instead of flat steel and round steel? Are there any examples of practical use?
Steel pipes can be used instead of flat steel or round steel, and some of the structures on the buildings are connected and grounded by using steel pipe handrails on the walls of their daughters.
Q:Between the MEB and the power distribution cabinet with wire with the flat and why
Even if there is no condition to make the ring flat steel belt, the ground terminal box is usually reserved for the access pipe. If multiple power line is recommended to see 500 2.7. central area substation, but also set the MEB based, attracted special line, and the reinforced layer access line; flat steel (copper) can save you, ha ha
Q:Connect the equipotential terminal box to the ground flat iron. Can I use plain flat steel?
Equipotential terminal box is the protection main buildings, water gas pipes, heating and refrigeration, cooling system, link building components such as metal parts, in order to meet the anti shock protection requirements of the electrical contact voltage of less than 50V. Is an important component of modern building electrical appliances, is widely used in high-rise buildings.
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.
