How to distinguish and regulate the voltage level of transmission power? There is no particularly strict standard, and as the line voltage level becomes higher and higher, the distinction between voltage levels also changes somewhat. At present, generally speaking: 35kV, 110kV, 220kV, and 330kV are high voltages; 500kV, 660kV, and [...]
Electricity generated by thermal power plants, hydropower plants, nuclear power plants, etc. is sent to the grid, which is then distributed to users. Due to the long distance between the power plant and the user, the electric energy will be lost during the transmission process, which is called line loss, [...]
The load on the cross arm can generally be decomposed into three types: lateral load, longitudinal load, and vertical load. The lateral load is the load along the direction of the cross arm, such as the direct pole commercial wire, the horizontal wind force of the ground wire, the corner [...]
1.hot dip galvanizing solution The total content of impurities (except iron, tin, aluminum and nickel) in the zinc solution used for hot-dip galvanizing should not exceed 1.50% of the total mass. Refer to GB/T470 for the impurities referred to. 2. Surface treatment requirements before galvanizing 2.1 Before galvanizing, the surface [...]
1.According to the function and structure, it can be divided into suspension clamps, tension clamps, UT clamps, connecting fittings, splicing fittings, protection fittings, terminal connectors, T-type clamps, busbar fittings, guy wire fittings, etc.; It can be divided into line fittings and substation fittings according to the purpose. 2.According to the [...]
