Some of these manufacturers include Siemens, Kruger, Aluminium X, ThyssenKrupp Access, Clark, Kohler and Thule. These manufacturers all offer high quality bus bars that can be used for a variety of applications. Therefore, when deciding on a busbar system, one needs to determine which specific type of application the busbar will be required for.<br><br><br>The most important factor when determining a busbar rating is the current capacity of the equipment. A current capacity calculation is used to determine the maximum load that the system can carry. This calculation is based on the dynamic pressure (dynamic lifting force) and tensile strength of the individual bars. Most manufacturers provide a current capacity calculation on their websites, so this step is not very difficult to complete.<br><br><br>To complete a current capacity calculation, two measurements must be made. These measurements are the dynamic pressure, as well as the tensile strength of each individual bar. To determine the required load, you can use the following formula:<br><br><br>Current capacity is usually calculated using standard busbar ratings bus configurations. However, if the application is highly demanding, or the equipment is expected to perform for prolonged periods of time (such as a power generator), then high current consumption may be required. In these instances, it is often necessary to purchase specialised high power systems, that possess the capability to meet the demands of the application. To determine the maximum allowable current, it is often necessary to consider the load of all three phase conductors in the system.<br><br><br>If the current consumption is determined, then this number is subtracted from the maximum allowable current. The resulting value is the maximum achievable current and is often referred to as the maximum allowable overload, or MOP. This calculation is required to ensure that the busbar systems will operate within their maximum safe working range and so should always be performed before purchasing any equipment.<br><br><br>Once the maximum current is calculated, you can then calculate the required load on each individual bar. For single phase busbar systems, the required load is the maximum achievable current multiplied by the number of bars. Again, the calculation is based on the maximum allowable overload. Single mode and isolated earth wiring designs will have different requirements for the load, as will many other types of systems. The three phase conductor will be able to supply the entire rated current, so it is often unnecessary to include this number in a sandwich bus duct specification.<br><br><br>When evaluating the standard MOP rating, there are many other factors that can affect this calculation. Isolation of the wire in any form (i.e. thermal, magnetic or electrical) can alter the MOP rating. Moreover, the wire can be made to contain more than one insulated conductor, all of which can affect the rating significantly. The best way to reduce these effects is to place the isolated conductor between the two bars that make up the standard MOP rating. This way both the thermal and the electrical conductors are effectively isolating, allowing a higher MOP rating to be obtained.<br><br><br>As well as the effect of thermal and/or electrical isolation, there is the effect of magnetic fields. If you beloved this information and also you desire to acquire guidance regarding [https://www.rhibusbar.com/product/electrical_power_bending_busbar.html visit our website] generously stop by the page. Standard busbars designed for use with short circuit systems can be subjected to significant variations in their RMS rating due to this factor. It should be noted that the effective RMS rating is only affected to an extent where the metal surface will become damaged, though this would normally only be seen in the case of improperly manufactured bustrunking equipment. Where this is the case, a carefully designed system will overcome the effects of magnetic fields.<br>' |
