Diamond Power Infrastructure has commissioned its seventh Medium Voltage and Extra High Voltage (MV and EHV) power cable production line at its Vadodara manufacturing facility. The new line employs Continuous Catenary Vulcanisation (CCV) technology for cross-linked polyethene cable manufacturing and represents a notable upgrade in production capability. The commissioning forms part of a sustained capacity expansion and technology modernisation programme at the company. The addition further strengthens integrated manufacturing for MV and EHV cables.

The facility will cater to utilities, renewable energy projects, industrial infrastructure, metro rail, smart cities, data centres, transmission projects and underground power distribution networks. The company said the expanded capability is intended to support higher voltage underground transmission and specialised transmission projects. Three additional MV and EHV cable lines are under installation and are expected to become operational before 31st March 2027.

CCV is described as an advanced, globally preferred process that delivers uniform cross-linking, lower partial discharge levels and improved electrical stress handling. The process yields consistent insulation quality, higher voltage endurance and enhanced thermal stability, which together reduce failure rates and extend service life in critical transmission applications. Enhanced automation and continuous production are said to improve manufacturing efficiency and facilitate compliance with international utility specifications.

The company characterised the market outlook for MV and EHV cables as driven by renewable integration, underground cabling, grid modernisation and growth in high voltage transmission systems. Diamond Power said capacity utilisation across organised manufacturers remains high and that technology intensity and testing requirements create significant entry barriers in the EHV segment. Management indicated that the commissioning and the planned lines position the company to participate in a multi-decade investment cycle in power infrastructure.
