The difference between standard copper row and high voltage cable

 The difference is as follows:


(a) In terms of current carrying capacity, wire and cable are for carrying small currents, busbars are for carrying large currents;


from the structural form, wire and cable is flexible (internal copper core external insulation layer) can be bent, bus bar is rigid (internal rigid copper row external steel or aluminum alloy shell) can not be bent, the need for specially made bend through;


From the point of view of the use of characteristics, the installation of wire and cable production trouble, each power equipment need to be independently wired, while the bus bar is easy to install flexible, not easy to install errors, a bus bar can be used for many points of equipment at the same time with electricity.



The principle is the same, copper row because of a single flow area is larger so dynamic stability and thermal stability are better than the cable, so the high current load or power supply is generally connected with closed busbar, but because the copper row is a rigid connection so the distance is long when the need to install expansion joints.


Use occasions: busbar use copper row, electrical panel cabinet connection between the use of copper row, dry change and low-voltage cabinet connection between the use of copper row, the connection between the generator and the booster change between the use of copper row. Other electrical equipment connection between the use of cable.


Among them, the standard high-voltage copper cable type specifications, high-voltage copper cable specifications high-voltage cable specifications are: YJV is a high-voltage copper-core cable, the model now has 35, 70, 120, square, etc.. Today's equipment transformers can use 70, including other equipment using 35 and 50 basic less used.


Another is the low-voltage cable. High-voltage hard copper cable models common high-voltage cable models are: WDZA-YJY23, WDZA-YJLY23, WDZB-YJY23, WDZB-YJLY23, WDZC-YJY23, WDZC-YJLY23, NA-YJV, NB-YJV.

Description of cable requirements for electric vehicle charging modes

 With the development of science and technology, as a means of transportation for daily travel, cars will continue to change in the future trends. Among them, electric vehicle charging connectors and charging cables have become a trend for the development of electric vehicles. Electric vehicles generally have two charging connection methods, one is the vehicle's built-in matching charging connector, and the other is a common charging pile in public places. Compared with the charging pile that comes with the car's own charger, which charging efficiency is more efficient? First of all, compare the charging connectors of electric vehicles with charging piles: household appliances are all 220V, and the same is true for appliances with charging piles. Because the input power of the power supply is limited, it takes longer for the car to come with its own charger. On the contrary, charging piles in public places use three-phase alternating current, and the input power can reach 380V,...

Learn more about the development history of OMG cable manufacturer

 In modern society, cables play an obvious role in life. In the early 20th century: Simple cables based on copper wires began to be used for charging electric vehicles. However, the cable transmission efficiency and safety of this period were poor, making it difficult to meet the growing charging needs of electric vehicles. In the following decades: cable design was continuously optimized, using highly conductive metals, multi-layer insulation and intelligent control technology to significantly improve performance. Cables during this period had significant improvements in transmission efficiency and safety. International standardization: With the rapid development of global charging infrastructure, a number of international standards and specifications for cable connections have been introduced, laying the foundation for the standardized application of electric vehicle charging cables . These standards regulate the design, manufacturing, testing and use of cables to ensure safety a...
