Services
Emergency Electrical Service
Terminal Andrae provides round-the-clock emergency electrical services for industrial and commercial clients. Our trained technicians respond to power outages, equipment failures, and safety hazards at any hour. With rapid deployment capabilities across Southeastern Wisconsin, we minimize downtime and restore operations swiftly while adhering to strict safety protocols.
Preventative Maintenance
Our preventative maintenance programs include thermal imaging, power metering, and equipment testing to identify potential issues before failures occur. Regular inspections extend equipment lifespan, reduce energy costs, and ensure compliance with OSHA and NFPA standards for commercial and industrial facilities.
Medium Voltage Construction
Specializing in 600V-69kV systems, we design and install medium voltage electrical infrastructure for industrial plants and large facilities. Our certified engineers implement safe, code-compliant solutions for power distribution, including ring-main and parallel feeder configurations tailored to client operational requirements.
Infrared Thermography
Using advanced infrared technology, we detect hidden electrical hotspots that indicate potential failures. This non-invasive diagnostic tool identifies loose connections and component wear in energized systems, allowing proactive repairs that prevent costly outages and safety hazards.
Structured Cabling
We install and upgrade voice, data, and security cabling systems for commercial buildings. Our BICSI-certified team designs scalable infrastructure solutions that support current and future communication needs while ensuring optimal performance and code compliance for Wisconsin businesses.
