Description
Product overview
A ring network cabinet is kind of fully-insulated and fully-enclosed common box type modular ring network switchgear, and is the main equipment for realizing ring power supply of the grid. Ring network refers to the ring power distribution network, i.e. the power supply mains form a closed loop. The power supplies electricity to the ring mains, and the power electricity is then distributed outside from the mains via the HV switch through each circuit.
The standard modules of the ring network cabinet include model C, C1, F, V, V1, S, D, M, Cpt, P and BR/L. Different functional modules can be combined into non-expandable units randomly. When it is necessary to have 7 or more unit modules to be connected, different modules can be designed into expandable units through special connectors, to achieve diversified unit combinations, and maximize the power supply and distribution design schemes required by different users.
