High and Low Voltage Complete Equipment Project Contracting
High and low voltage (HV/LV) project contracting involves turnkey solutions covering design, supply, installation, commissioning, and maintenance of electrical systems from 415V to 132kV, including automation and monitoring technologies.
Scope of HV/LV Contracting
Design and Engineering: Contractors provide full design services for HV and LV systems, including substations, distribution networks, and interconnecting feeders. Designs comply with prevailing standards and safety regulations, ensuring reliable and efficient power distribution . Equipment Supply: Complete electrical equipment packages include:
- Low-voltage distribution cabinets with advanced protection, remote monitoring, and automatic switching functions .
- High-voltage switchgear using vacuum circuit breakers or SF6 gas insulation for high breaking capacity and insulation performance .
- Transformers (dry-type or oil-immersed) optimized for efficiency, low noise, and long lifespan .
- Automation control systems integrating PLC, SCADA, and data acquisition for real-time monitoring, fault diagnosis, and operational efficiency . Installation and Commissioning: Contractors handle the installation of HV/LV equipment, substations, and interconnecting networks. This includes testing, commissioning, and ensuring systems operate safely and efficiently . Maintenance and Inspection: Ongoing maintenance services ensure system reliability, safety, and compliance with legislation. Advanced monitoring systems, such as real-time electrical parameter analysis, enable predictive maintenance and self-protection of equipment .
Safety and Compliance
Contractors implement rigorous HV and LV safety protocols to protect personnel, assets, and the public. Accreditation, such as NERs certification, ensures independent and compliant solutions for contestable connections and electrical infrastructure projects .
Applications
HV/LV contracting services are applicable to:
- Industrial and manufacturing facilities
- Commercial and residential complexes
- Infrastructure projects including renewable energy (solar, wind) and charging stations
- Utility and power grid operators requiring substations and network upgrades
Advantages of Turnkey HV/LV Contracting
