For more than 100 years, Belden has been a leader in the design and manufacturing of insulated wire, cable and related products. Since then, Belden has transformed itself from a cable company to a signal transmission solutions provider with a complete product portfolio including cable, connectivity and networking products.

1941-1960 Belden Expansion1941 - 1960

During World War II, and the decade and a half of growth that follows, a number of buildings are added to the Richmond Plant to allow for expansion. Wire mill operations are transferred from Chicago to Richmond to make the Richmond plant completely independent and self-sufficient. At nearly 700,000 square feet, this would be Belden's largest manufacturing facility for more than 70 years.



Belden Supports the War Effort1942

Belden shifts its manufacturing to exclusive support of the war effort. Its products are used in tanks, airplanes, mobile radios, submarines, ships, jeeps and a variety of other military machinery.  



Belden continues to innovate1945 - 1980

After World War II, Belden begins to establish its clear leadership in wire and cable technology through research, engineering, and product development. The company becomes one of the first wire producers to apply plastic insulations to wire and cable and seeks out market niches that require sophisticated and high quality products, adding value in insulation, cabling, shielding and jacketing.

The Company moves to its new headquarters located south of Richmond, Indiana. Belden merges with Crouse-Hinds Company, a highly regarded manufacturer of electrical products located in Syracuse, New York.

Belden merges with Cable Design Technologies Corporation2004

Belden merges with Cable Design Technologies Corporation (CDT). CDT was incorporated on May 18, 1988 with its headquarters located in Pittsburgh, Pennsylvania. Some of its operating companies, however, were more than 100 years old. In 1985, CDT's predecessor company, Intercole, Inc., a Company traded on the American Stock Exchange, was acquired by the Northern Group, which subsequently took it private. In 1988, the Company underwent a recapitalization pursuant to which Golder, Thoma, Cressey Fund II purchased a controlling interest in the Company, with the Northern Group retaining a smaller interest. From 1988 to 2004, acquisitions were an important part of CDT's growth strategy.
