Indoor Substations

Indoor Substations

Indoor or chamber substations are an important part of any low voltage network in larger cities and in harsh environments. In many cases today the same networks use large kiosk substations for the same application. However in the central business districts of the capital cities and harsh environments such as the snowfields, low voltage distribution switchboards will always be located indoors. From a simple 500kVA form 1 constructed switchboard to a form 2a constructed switchboard for three 2mVA transformers with busties, Weber South Pacific’s design and manufacturing teams can meet customers’ requirements. Such switchboards are to rigid customer (utilities) specifications and do not necessarily meet the requirements of AS3000 due to operational needs.

As with kiosk substations the aging networks often present design challenges for retrofit indoor substations. On one hand we have the problem of cables that cannot be moved due to aging insulation and on the other hand the limited access to the location present many challenges.
