STRUGGLING WITH OUTDATED WWTP CABLE
Wastewater treatment plants (WWTP) need reliable wire and cable solutions to keep their drive systems and pumps running smoothly—anything less could lead to frequent interruptions of this critical service.
One facility on an island in Massachusetts was struggling with their outdated power cable. All of their low voltage variable frequency drives (VFDs) powering the pumps were installed underground, great for combating the corrosive environment, but this led to constant electromagnetic interference (EMI) issues.
IMPORTANCE OF PROPERLY TERMINATED CABLES
VFDs inherently generate more EMI that gets radiated into the environment. Without the proper cable, this can induce voltages, currents, and crosstalk onto adjacent equipment. In this case, it was causing short interruptions in performance that had a rippling effect throughout the entire plant and ultimately the local community.
Service Wire’s experienced VFD experts were able to quickly identify the issue and recommend a solution, the ServiceDrive® VFD Cable System. Unlike the outdated cables previously installed in the facility, ServiceDrive® VFD cable uses a 5-mil copper tape shield with 50% overlap to ensure full electrical containment, reducing EMI emissions from the drive and motor.
TINNED COPPER CONDUCTORS
In examining the plant’s EMI issue, the Service Wire team quickly identified another concern: the wire and cable used throughout the entire facility was below current standards and in need of replacement to operate efficiently. ASTM B-33 rated tinned copper was recommended and later installed to help the facility get back up and running.
Tinned copper better protects against oxidation and corrosion, especially in environments prone to long-term salt water exposure like those found in wastewater treatment plants. Without this added protection, corrosion results in brittle, hazardous wire that poorly conducts electricity, endangering plant and personnel.
