Product Introduction
Overview
• A ground mounted distribution transformer with cable box is a liquid-filled three-phase unit installed on a concrete pad at grade. Segregated MV and LV cable boxes offer shielded, touch-safe terminations and flexible entry directions. The arrangement supports underground feeders, provides touch-safe connections, and simplifies interface with switchgear, ring main units, and low-voltage panels on modern distribution networks in space-constrained, reliability-focused installations worldwide today.
Application
• Ground mounted distribution transformers with cable boxes are applied on utility feeders, industrial plants, renewable interconnections, and commercial developments using underground or mixed cabling. They interface medium-voltage networks with low-voltage switchboards, providing safe terminations near load centers. The ground-mounted arrangement simplifies civil works, shortens cable runs, and supports phased capacity upgrades with minimal disruption to surrounding operations and future reinforcement.
