The three heads of three-phase power are called phase lines, and the three tails of three-phase power are connected together. The neutral line is also called "zero line". The reason for calling the zero line is that no current flows through the neutral line of the three-phase equilibrium moment, and then it is directly or indirectly connected to the earth, and the earth voltage is also close to zero.
The ground wire is a line that reliably connects the earth of the equipment or the electrical appliance to the earth, and is a good solution to prevent electric shock accidents.
Under normal circumstances, the three-phase circuit uses red, yellow, and blue colors to indicate three live lines, and the zero line uses black. In a single-phase lighting circuit, generally yellow indicates a live line, blue is a neutral line, and yellow-green is a ground line. In some places, red is used to indicate the fire line, black is the neutral line, and yellow and green is the ground line.
The electric appliance has a neutral line and a live line, thereby forming a passage, so that the electric current has an electric current to pass through, and the zero line is uncharged.
The ground wire is not powered regardless of whether the switch is off or not. Its main function is the grounding you mentioned. In order to avoid the occurrence of electric leakage accidents or high-potential potential hazards to humans, high-power electrical appliances have a grounding wire that can be used to introduce excess current or strong electric potential into the earth through the ground wire.
PCD END MILL REAMERS
PCD End Mill Reamer is a multi-diameter tool allowing for excellent hole size and concentricity between diameters.Nowadays, more and more automotive gearboxes are made of die-cast aluminum alloys with complex shapes. There are many stepped shaped holes on the gearboxes, in order to meet high efficiency and high precision processing, it is especially suit for machining with PCD Step Reamers.
Choosing PCD end mill reamer is very often the best way to reduce the total cost, using highly advanced PCD reamer can reduce the number of tools needed and increasing productivity, thus lowering your production unit costs considerably.
Advantages:
Unique guidepad geometry allows for excellent roundness and straightness, even in an interrupted cut condition.
Surface roughness is reduced obviously.
