Copper is a high current conduction products for high and low voltage electrical appliances, switching contacts, distribution equipment, busbar and other electrical engineering, is also widely used in metal smelting, electrochemical plating, chemical and caustic soda and other large current electrolysis smelting works. Electrical copper has low resistance, bendability advantages. 
Copper, also known as copper bus bar, copper or copper busbar bus, grounding copper bar is made of copper material production, rectangular section or chamfered (rounded) long rectangular conductor made of aluminum material called aluminum row, in the circuit from the current supply and connecting electrical equipment role. Quality copper bus request is executed GB / T 5585.1-2005 standard.
Since the electrical properties superior to copper, aluminum, copper electrical equipment, especially power distribution apparatus has been widely used; in general distribution cabinet in the A, B, C, N phase busbars and the PE busbar are made of copper; copper in use phase is generally marked with the letter color logo or coated with paint, a copper phase is identified as "yellow" color, B phase as "green" color, C phase of the "red" color , N phase "light blue" color, PE bus to "yellow-green" color.
Copper is mainly used in the last line (high current phase, neutral and ground will be used copper), connected to the electrical cabinet of a higher current copper components are used, such as a row of electricity cabinet between the cabinet and the cabinet is connected row mistress, mistress branch busbar row assigned to each side of the cabinet electric switch (isolating switches, circuit breakers, etc.) on. There are tin-plated copper also bare copper, copper in the electrical cabinet connections generally do tin plating treatment and an embossing treatment or add a conductive paste. Heat shrink sleeves have spare office protection, and some are with insulating paint. With copper-carrying capacity is the most important consideration, according to the size of the current selection of a suitable copper, the screw connection must be tightened, otherwise there will be pillow melting copper may be current is large.
For the price of copper bus bar of course, the standard, the better, "copper price calculator" to help you solve the ribs on the copper price is difficult. This software is mainly used for copper sales process.
