Our Services
Substation Electrical Construction & Engineering
VoltCore Electrical delivers full-service substation electrical construction from site preparation through energization for utilities, industrial facilities, and renewable energy projects.
Full-Service Substation Construction
VoltCore Electrical provides comprehensive substation electrical construction services for distribution and transmission substations ranging from 12.47kV to 345kV. Our experienced crews handle all aspects of substation construction including foundations, steel erection, equipment setting, bus work, cable and wire installation, grounding, and commissioning.
Protection & Control Systems
Modern substations require sophisticated protection and control systems to ensure reliable operation and rapid fault isolation. Our team installs and commissions protective relay systems, SCADA interfaces, revenue metering, and communication equipment. We work with all major relay manufacturers including SEL, GE, and ABB.
Testing & Commissioning
Every substation we build undergoes rigorous testing and commissioning procedures before energization. This includes insulation resistance testing, contact resistance testing, transformer turns ratio testing, relay calibration, and functional testing of all protection and control systems. We provide detailed test reports and as-built documentation.
Upgrades & Retrofits
Aging substation infrastructure requires periodic upgrades to maintain reliability and comply with current standards. VoltCore performs substation upgrades including relay replacements, breaker retrofits, transformer changeouts, and control system modernization — often while the substation remains energized.
