Infographic: designing enclosures for resistors

Power resistor enclosures provide a number of functions, including protection from harsh weather conditions, cooling and preserving the safety of the public. Each of these specifications will vary, dependant on the exact requirements of the client, and the resistor they purchase; however, a full understanding is crucial to the design phase.

The research stage is usually undertaken when the customer provides an initial specification, but on some occasions this does not happen; therefore it is the manufacturer's responsibility to ask those important questions.

The infographic explains five questions that must be answered in order to design and manufacture an effective enclosure that meets all the required specifications. These queries cover the final resistor environment, industry challenges, aesthetic considerations, health and safety and choices around shipping and installation. By thinking about these points early, the final product can be designed to meet each and every requirement.

Andrew Keith, engineering director at Cressall Resistors says: "We produced this infographic to provide design engineers, as well as the end user, a checklist of things to consider when they are planning their resistor and corresponding enclosure.

"Sometimes enclosures can be left as an afterthought, but this will rarely achieve the most efficient, advantageous solution. Thinking about the enclosure at the same time as designing the resistor is crucial to ensuring the final product will meet all the requirements, reducing the risk of compromises having to be made."
