Powell Industries is a strategic provider of highly complex integrated electrical power distribution and control systems. For this purpose, the company has developed solutions such as its “Power Control Room” (PCR^®) – a controller and control cabinet container, which is used in a large number of markets, such as substations for oil and gas projects and transportation systems. “Our PCR^®s ship to all 50 US states and more than 70 countries and are installed there – from the desert and heat of Saudi Arabia to the low-temperature North Slope of Alaska,” says Rick Deiss, Production Designer.

Optimizing Production, Transport and Connection – Thanks to Levers

To make its PCR^®s even more innovative, the Houston-based company relies on lever connection technology developed by WAGO, in addition to its maintenance-free, vibration-proof Push-in CAGE CLAMP^® spring pressure connection technology. The WAGO lever offers a tool-free conductor connection like none other on Earth. For wiring in the factory as well as at the customer’s site especially, it makes the process faster and safer. This offers real added value – especially for large controller and control cabinet containers. “Some PCR^®s so large they need to be split apart and shipped in sections,” explains Rick Deiss, Production Designer at Powell Industries.

During assembly of a larger Power Control Room, the individual sections/rooms are first physically joined together. Then the interconnecting cables between the individual sections must be securely connected in so-called “split boxes” for the wiring. After that, they are “disconnected” again before the PCR® is disassembled once more for shipment to the customer – which is no problem, thanks to pluggable connectors with levers from WAGO. But it wasn’t always like that:

In the past, the cable connections often came loose during shipping of the split boxes, due to vibration and installation errors. Therefore, upon delivery, prior to connecting the rooms together, engineers would need to go into the box, check the wires and re-tighten the screws that held them in place using calibrated torque screwdrivers. “This was really troublesome, time-consuming and costly, not just in terms of labor – the special tools this required also had to be purchased and recalibrated annually,” recalls Rick Deiss.
