How to make an entrance

摘要

Chris Lloyd, Sales and Marketing Manager for Spelsberg UK, explains the strengths and weaknesses of different cable entry options and provides details on the latest developments. When specifying an enclosure for electrical applications one of the key considerations has to be cable entry. The cable entry points of an enclosure can help to determine the overall level of ingress protection (IP) provided against the external environment as well as cable retention force and crucially, installation speed, all-the-while balancing utility with cost. Recent developments in materials, moulding technology and push-fit grommets have changed the options that are available providing a far more specialised solution for a variety of applications; time to reassess the options then. Making the right choice of enclosure and entry method can make the difference between a profitable job and a loss, as well as guaranteeing the all important safety of installers and end users.
