Suddenly!A circuit failure occurred in a building in Shenzhen,and the CESKO maintenance team was urgently dispatched!

　　Bus ducts,as important transmission and distribution lines,are becoming increasingly common.CESKO:"Only by purchasing high-quality bus ducts can we effectively ensure the safety of our lives and property There are countless examples of serious accident consequences caused by the use of inferior bus ducts.

　　For example,there was a bread supplier in China who chose a certain brand of bus duct at a low price due to the need to upgrade their factory equipment.However,due to the problem of cutting corners in the products of this brand of bus duct,serious safety hazards were buried.After a period of time,more than 30 production line machines were damaged due to circuit short circuits,resulting in a major safety accident where the entire factory was burned down.

　　A thousand mile embankment collapsed in an ant nest.No one wants a major safety accident to happen,what we need to do is to prevent it before it happens.CESKO reminds that only by choosing high-quality bus ducts can one truly ensure the safety of their lives and property.

　　Next,Mr.Cao will take you to see the chaos in the busbar trunking industry.

　　1、The chaos in the bus duct stunned your chin

　　The surface of the inferior bus duct looks great,but in reality,its interior is unbearable to look at.All of this is a trick played by inferior manufacturers to deceive consumers and falsify products in order to save costs,but it is indeed a potential safety hazard for consumers.

　　The market for bus ducts is mixed,and some manufacturers often attract customers with the"lowest price".Cao Gong can easily list some common problems when choosing bus ducts:

　　1.Copper at both ends and aluminum in the middle

　　Aluminum has lower conductivity than copper and is also cheaper in price.Some manufacturers deceive customers by using aluminum bars instead of copper bars in the middle of bus ducts in order to save costs,which poses a safety hazard to customers'electricity consumption.

　　2.Poor insulation material quality

　　Some manufacturers may use inferior insulation materials to wrap the bus duct conductors,such as heat shrink tubing or low-grade polyester tubing supported by inferior materials,resulting in poor insulation and heat resistance.After use,it is easy to cause the bus duct to heat up and short circuit,thereby affecting the overall service life of the bus duct.

　　3 Welding Soft Connections

　　If welding is performed between soft connections,oxidation and heat generation are more likely to occur,which in turn affects the conductivity and lifespan of the bus duct.

　　4.Poor welding process

　　Poor welding process of bus duct can lead to fracture at the welding point of the shell,which in turn affects the mechanical strength and service life of the bus duct.

　　5.Cutting corners in tin plating

　　Tin plating is used to increase the conductivity and oxidation resistance of bus conductors.If the tin plating layer is too thin,it is more likely to cause oxidation corrosion on the surface of the bus duct,thereby affecting its overall life.

　　6 brass instead of purple copper

　　Some manufacturers may use T3 brass instead of T1 and T2 copper to save production costs.However,T3 brass generally has low purity and resistance that does not meet the conductivity requirements,which can lead to poor electrical performance of the bus duct,increased power consumption,and even short circuits due to high temperature rise.

　　7.The shell is as thin as a cicada's wing

　　Some manufacturers use aluminum shells as thin as cicada wings,which are more prone to deformation,have low mechanical strength,and are easily damaged.

　　8.Poor connection structure

　　Poor connector connection structure can easily lead to structural looseness,breakage,and moisture damage at the connection of the bus duct.In severe cases,the bus duct may be burned due to short circuit.The copper plate in the connector shown in the figure will corrode after being dampened,resulting in decreased conductivity and increased power consumption.

　　9.Side panel without heat sink

　　Some manufacturers,in order to save costs,use shell side panels without heat dissipation structures in the production of bus ducts,which is not conducive to the heat dissipation of bus ducts and can also reduce the service life of bus ducts.

　　10.Cutting corners and reducing materials to half the zero line

　　The bus duct required for commercial electricity requires 100%of the N(zero)line as the main phase line,but some merchants may cut the N(zero)line in half to save costs and deceive consumers.The halving of the N(zero)line will bring serious safety hazards,just like the example of cutting corners by only 2 centimeters,which resulted in a short circuit and burning of the entire bus duct during use.

　　2、How to correctly select and use high-quality bus ducts?

　　Bus duct is a front-end main line used to replace cables in power transmission and distribution.Whether a high-quality bus duct can be selected is directly related to the safety and service life of the main power transmission and distribution equipment.

　　Cao Gong reminds us that in order to correctly select bus ducts,we must pay attention to the following four points:

　　1.Pay attention to bus duct conductors

　　If copper is used as the conductor in the bus duct,both T1 and T2 copper can be used as materials,but it is important not to use brass as it has poor conductivity and is prone to heat generation;

　　Secondly,the purchased materials must be consistent both inside and out,with the biggest concern being copper on the outside and aluminum or other materials on the inside;

　　In addition,we also need to pay attention to behaviors such as excessive punching in the middle of the conductor and untreated surface,which are actually the manufacturer's cutting corners.

　　2.Pay attention to the shell material

　　There are three common materials for shells:aluminum,iron,and aluminum alloy.Some inferior manufacturers may use inferior aluminum plates,and do you dare to use aluminum shells that are prone to deformation?

　　There is also a busbar duct with side panel structure,and attention should be paid to whether the mechanical strength is sufficient.If it is too soft,it is not safe.

　　3.Pay attention to insulation materials

　　We can choose DuPont insulation materials or high-quality domestic brands as our preferred insulation materials.Although the price varies,high quality ensures that the bus duct is sufficiently safe.

　　It is best to have a side plate heat sink structure,which is conducive to the dissipation of heat generated by eddy currents during the operation of the bus duct.

　　4.Pay attention to other auxiliary materials

　　In addition to the three main materials introduced above,we also need to pay attention to the performance of the circuit breaker,support device,protective device,and other aspects of the plug-in box.
