History of CMC

CMC^®'s Utility sales effort originated with a brand label agreement in 1978 with a major transformer manufacturer to market secondary transformer and pedestal connectors through their sales force. The sales agreement was concluded at the end of 1983, at which time CMC^® assumed all direct sales and marketing responsibility.

CMC^® is a full line manufacturer of aluminum and copper connectors, offering both mechanical and compression designs. Products are marketed to utility companies, original equipment manufacturers and commercial/industrial accounts. In addition to its utility products, CMC^® manufactures connectors for meter socket terminals, load center neutral bars, switch gear terminations, commercial panel boards, circuit breakers, motor controls and pole line hardware, wind energy products, solor energy products, and enclosures.

CMC^® has five primary sites totaling over 300,000 square feet of production, warehouse and office facilities. Headquarters are located in Ohio with branch locations in Alabama, Tennessee, Canada, and Mexico. 

CMC^® ALUMINUM CONNECTORS
Connector Manufacturing Company is proud to supply the industry with a line of electrical connectors fabricated from the very best aluminum alloy, 6061-T6. This choice was predicated upon many design factors to achieve the best balance between strength and conductivity. Both factors are of extreme importance in connector design calculations. The aluminum extrusions have almost a two-to-one advantage in yield strength to that of a sand cast alloy 356 or die cast alloy AXS679 permitting an extra margin of safety while the conductivity is a most favorable 43% IACS.

The set and socket screw mechanical connectors are designed to utilize the advantages of the 6262-T6511 alloy and temper for high yield strength while providing a connector of low stress. Screw pressure is designed to break through aluminum conductor oxide by the cold flow process that insures a low resistance connection. Sufficient pressure is maintained on the conductor to prevent the reforming of the aluminum oxide. The pressure, combined with the high conductivity factor, will result in a connector operating temperature below that of the conductor.

We therefore, offer these advantages in connector design:

• Compact design
• High strength aluminum
• Relative light weight construction
• Economy
• Third party certified tested products in accordance with Underwriters Laboratories and the Canadian Standards Association requirements for listing as well as ANSI C119.4, C119.1, Western Underground Guide 2.5 and RUS certification where applicable.

These factors together with our dedication for the highest quality ISO 9001:2000 certified standards available and an unsurpassed service level, provide our customers with maximum reliability.
