Disclosed on Tuesday, September 15, 2026, the contract covers the manufacture and supply of specialized medium-voltage and low-voltage underground power cables for the Mumbai distribution network.

The latest order marks the third consecutive year that Diamond Power has secured this major utility contract, underscoring its technical competency in fabricating water-tree retardant (TR-XLPE) cables. Engineered with longitudinal and radial water-blocking construction, the supplies are specifically designed to withstand heavy coastal monsoon conditions across the metropolitan region.
