Hovednettet

Hovednettet is a term used in Nordic contexts to denote the main network, the backbone that connects subordinate networks within a country or sector. It refers to the central, high-capacity part of a system that enables long-distance transport of information, power, or people between major hubs, while regional and local networks handle access and distribution. The term is most commonly used in telecommunications and electrical infrastructure, but in some contexts it may also describe the principal routes in transport planning. It emphasizes the essential, high-capacity links that provide core connectivity and resilience for the wider network.

In telecommunications, the hovednettet comprises long-haul fiber-optic links, core routers and switches, and interconnection points that tie together cities and international links. It is designed for high capacity, low latency, and high reliability, and is built with redundancy and diverse routing to reduce the risk of outages. Ownership and management typically involve national carriers, state or government entities, or regulated operators, with strict cross-border interconnections to neighboring networks.

In electricity, the hovednettet refers to the high-voltage transmission grid, typically operated by a national grid operator. It carries large power quantities over long distances from generation sources to regional distribution networks and is linked to neighboring countries to ensure security of supply. The grid relies on substations, high-voltage transmission lines (AC and sometimes HVDC), and advanced grid management to balance supply and demand and maintain stability.
