Not many people taking a flight out of Logan or T.F. Green airports will notice the external power connector cables on the ground that attach airplanes to the airport power source after they land, but they may be surprised to know that many of those connectors are made right here in the Spindle City.

Formed in 1994 and located at 994 Jefferson St., Anderson Airmotive Products Company Inc. supplies the A/C and D/C power connectors and battery connection supplies to all major airlines, as well as military branches including the Air Force, Navy and Army. The connectors provide as little power as 28 volts to as high as 400 volts.

While a plane in the air is run by batteries, on the ground that power source must come from somewhere else provided by the airport. Those connectors are then plugged in to the airport and the plane where it then powers the plane’s lights, air-conditioning and other systems generally powered by the batteries. Anderson manufactures those plugs to be connected to the ground power source.

“Due to environmental regulations, auxiliary power on airplanes can’t be used on the runways and it also gets too expensive to run as well. These are cables that are connected to the airplane and an external power source,” said Anderson President Ronald Steger. “It provides power for the A/C and the lights in planes and for jets, assists in them starting them. Every plane in the world has one of these.”

Originally, these connectors were made by Anderson Power Products of Boston, but in 1994, that company decided to eliminate several of its product lines — the power connector system among them. Steger, who was general manger of the of the company, decided to buy the product line from the company and moved to Fall River in 1994.

Since then, they’ve seen nothing but growth.

Starting with just six employees nearly a decade and a half ago, Steger said his workforce has since tripled to 18. Steger said one of the big reasons behind the growth is continuing to be innovative, keeping up with latest trends and trying to make this as convenient for the companies as possible. Where the cables used to only be sold as one unit, assorted parts for that one cable are now being sold in order to allow the customer to replace only the part they need instead of the whole units, which comes as significant cost savings.

And the strong Euro dollar has also helped since Anderson does a good deal of business overseas.

“Forty percent of our sales increase — make that 50 percent — is due to our market and product expansion over the last two years. Our intention when we moved here was to get into new product lines,” said Steger. “With the weak dollar overseas, we may be priced the same as other companies but the end cost to the consumers is much lower now.”

The plant is located in about 10,000 square feet of space, and Steger said not only is he a local manufacturer but he also gets most of his parts from local companies, even a neighbor in H&S Tools, which makes the machinist parts that go into the connector receptacles and a company in Rhode Island that makes the cables.

“We are the only manufacturer that is up to military specs, which make you go through extensive listing every three years,” said Steger. “Right now, about 20 to 25 percent of our business is from the military.”
