NSTAR Transformer Substation

The Issue

The NSTAR Transformer Substation utilities a noise reducing sound wall fence that satisfies the locals, as well as the Wellfleet Board of Health. The system relieves the neighboring community free of noise and visually hides the station.

The Challenge

NSTAR is the largest Massachusetts based, investor Owned electric and gas utility. It transmits and delivers energy to 1.1 million electricity customers and nearly 300,000 gas customers. One of their substations, though, was operating at a noise level above the regulated level. IAC Acoustics, whose products are available through Acoustical Solutions, was called to provide a solution. In order to reduce the transmitted noise, the IAC designed and engineers a custom installation of their Noishield F/S/S sound barrier system. This system uses of smaller, lightweight panels that allow great versatility in terms of configuration options.

The Solution

Within eight weeks of receiving the order, the project was complete. The treatment included (159) Noishield® FS/S panels 5″ thick, 24″ high (on center) and various lengths up to 20′. The panels are cold rolled A-60 steel, fabricated using 4 gauge materials for the solid side and 20 gauge materials for the perforated side of the panel. Fill materials used are fiberglass, non-corrosive, resistant to attack by fungus, fire-resistant, vermin proof and non-hygroscopic. It is free draining, self-supporting and retains physical and sound absorptive characteristics after long term exposure to the elements. All materials have a Class A fire rating.
