Medium-Voltage Distribution Network Modernization in the Middle East

1. Project Overview

In March 2026, JYDQ completed the supply and commissioning of pole-mounted medium-voltage switching and protection equipment for a distribution network modernization program in the Middle East. The project aimed to enhance grid reliability and reduce outage duration for residential and commercial consumers across multiple distribution feeders.

JYDQ supplied a comprehensive range of outdoor pole-mounted equipment including vacuum circuit breakers, load break switches, and integrated protection and control units. All equipment was designed for reliable operation under the region's challenging environmental conditions — high ambient temperatures, dust exposure, and intense solar radiation.

2. Technical Value & Impact

The pole-mounted solution offered significant advantages over traditional ground-mounted substations for this application: reduced land acquisition requirements, faster installation timelines, lower civil works costs, and simplified maintenance access. Each unit was factory-assembled and tested before shipment, minimizing on-site construction work.

JYDQ's equipment incorporated key design features for the Middle Eastern environment: UV-stabilized polymer insulators with extended creepage distance, IP65-rated stainless steel control cabinets with thermostatically-controlled ventilation, and anti-corrosion hot-dip galvanized steel support structures.

3. Customer Feedback

"The JYDQ equipment has been operating reliably since commissioning. The factory pre-assembly significantly reduced our on-site workload, and the technical documentation provided was thorough and professional. We have already placed follow-up orders for additional feeders."
