Long Distance distribution in Medium Voltage HTI (3200 or 5500 V)

Product catalog summary

Introduction
This document addresses the challenges of low voltage (LV) limitations in lighting projects, particularly for roads, motorways, and large sites. It proposes solutions using medium voltage (MV) technology to overcome these constraints.

Specifications and Solutions
The document outlines the limitations of LV sources, which are often unavailable near lighting courses, and suggests using a single electrical source with energy transport at 3200V or 5500V. This approach is suitable for extra-urban street lighting projects and can be implemented from existing LV or high voltage (HV) sources.

Examples and Case Studies
Several examples illustrate the application of MV technology:

Example 1: Road lighting using a 3200V single-phase network over 4500 meters.
Example 2: Road lighting with an exchanger using a 3200V network with multiple output feeders.
Example 3: Motorway lighting with a 5500V three-phase network over 22,000 meters.
Example 4: Great site lighting using a 5500V three-phase network.

Technical Considerations
The document discusses the feasibility of transporting HV along courses, the costs involved, and the management of administrative formalities. It emphasizes the autonomy and cost-effectiveness of MV solutions, which can reduce budgets by 15-30% and allow for future extensions and energy savings.

Equipment and Installation
Augier SA provides design and manufacturing services for step-up and step-down cabinets, transformers, and cables. The MV sources (3200V or 5500V) are transported by adapted cables, and transformers are installed near lighting columns to restore LV voltage.

Energy Saving and Management
The document highlights the potential for energy savings of 30-50% through the use of voltage variation/regulation devices and remote control systems (STEP) for monitoring and managing the MV networks.

Conclusion
Augier SA offers certified solutions for MV networks, providing autonomy, cost savings, and flexibility for lighting projects. The company is ISO 9001 certified and offers additional solutions for 950V networks.
