These new rotary tap switches can be configured for manual or motor operation, and have dual (continuous/intermittent) ratings from 100/150 to 1,600/2,400 amps at 600V and come in single, two or three-phase models. The switches are made to hold up under shock and severe vibration. They have a handle that accommodates two padlocks, nonferrous parts, an escutcheon, fire-retardant nontracking insulation, low operating torque, and high-pressure line contact. Models rated for 200 or more amps have silver-plated current-carrying parts. Models rated up to 1,000 amps have glass-fiber-reinforced bases, with fabricated bases for models rated over 1,000 amps. Modifications are available such as increased voltage and amperage ratings, angled terminals, key-interlock provisions, auxiliary switches for remote indication, an "off" position, and a mechanical-release handle.
Our LinkedIn systems and product design engineering group discusses if they are happy with their decision of remaining a technical contributor instead of becoming a manager.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
