Power line construction is the foundation of MHG Holdings. We build transmission lines, distribution lines and substations from 0.4kV to 220kV for industrial owners, industrial parks and power generation projects.
Our differentiator is that the main materials — spun concrete poles, steel poles, steel structures and hot-dip galvanizing — all come from factories within the group. Schedules do not depend on outside suppliers and quality is controlled from the source.
- Mobile construction crews with dedicated grid equipment
- Safety documentation and method statements per power-sector regulations
- Close coordination with local utilities during energisation
