Excuse me, what are the copper bars above 10x200 used for? Where are copper bars used in chemical and polysilicon industries and what role do they play? thank you

Copper bus is a kind of high current conductive product, which is suitable for high and low voltage electrical appliances, switch contacts, power distribution equipment, bus duct and other electrical projects, and is also widely used in metal smelting, electrochemical electroplating, chemical caustic soda and other ultra-high current electrolytic smelting projects. The electrical copper bar we supply has the advantages of low resistivity and high flexibility.

Copper bus, also known as copper bus, copper bus or copper bus and grounding copper bus, is a long conductor with rectangular or chamfered (rounded) rectangular cross section made of copper material, and aluminum bus made of aluminum material plays the role of transmitting current and connecting electrical equipment in the circuit. At present, the quality requirement for copper bus is GB/T 5585. 1-2005 standard.

Because the conductivity of copper is better than that of aluminum, copper bus has been widely used in electrical equipment, especially in complete sets of distribution equipment. The A, B, C, N phase buses and PE buses in the distribution cabinet generally adopt copper bars; In use, copper bus bars are usually marked with color letters or painted with color paint. A phase copper bus is marked with yellow, B phase is marked with green, C phase is marked with red, N phase is marked with light blue, and PE bus is marked with yellow-green.

This kind of elite talent for copper bar processing is also the most lacking in China at present. At present, there are many copper bar processing talents, which is a professional recruitment and job search website for copper industry talents.

Copper bus is mainly used for primary lines (copper bus is used for high-current phase lines, neutral lines and grounding lines), and copper bus is used for connecting high-current primary components in the electric cabinet. For example, a row of electrical cabinets are connected between cabinets by a main bus, and the main bus is distributed to switching power (disconnectors, circuit breakers, etc.). ) with a branch bus. There are tin-plated and bare copper bars, and the copper bar joints of electrical cabinets are generally tin-plated embossed or added with conductive paste. The spare parts are protected by heat shrinkable sleeves, and some of them are coated with insulating paint. The main consideration in using copper bars is the current carrying capacity.
