Installation requirements for supercapacitor transformers for communication base stations

1) A liquid confinement area be provided. 2) The transformer be filled with a listed less-flammable insulating liquid with a minimum of 300°C fire point. 3) The installation complies with all restrictions provided for in the listing of the liquid. A liquid confinement area, as indicated above and an automatic fire extinguishing system.

Rule 26-242 goes on to explain the installation and protection requirements for unit substations, depending on their design. Per Rules 26-300 through Rule 26-324, unit substations require fencing (which can be chain-link or wood-slat construction), unless they are already isolated via elevation

Construction requirements for vaults are detailed in Part III of Article 450. Section 450.42 in Part III, Transformer vaults, allows an exception to the three-hour vault requirement permitting a one-hour rated fire resistant rated room if equipped with an automatic extinguishing system.

When your transformer arrives on site, various procedures should be carried out to assure successful operation (installation, testing and various checkings). The successful operation of a transformer is dependent on proper installation as well as on good design and manufacture.

Supercapacitor solutions are sized to provide the appropriate amount of ride through time until the primary backup power source becomes available. For applications requiring power for only short periods of time or is acceptable to allow short charging time before use, supercapacitors can be used as the primary power source.

If transformers filled with conventional mineral oil or non-approved fluids would expose buildings and equipment to a release of oil, the transformer must comply with FM LPD requirements. This may include containment, separation distances, fire barriers, or water spray systems.
