Substation

With decades of design and manufacturing expertise, our Dossert® product line offers a wide range of substation accessories for deployment by electric power utilities. Our substation products feature superior product performance designed to improve the reliability of the critical electrical and optical infrastructure used for the transmission and distribution of electricity.

AFL's substation accessories are made for low voltage up to 765 kV applications that involve cable, pipe, flat or tubular bus and integral web connections. Substation accessories cover everything inside the fence including supports, couplers, connectors, expansions, taps, terminals, reducers, bus vibration dampers, stud connectors, end plugs and hardware.

Complementing the entire substation family, Swage grounding, bus and cable accessories use a compression technology process called "swaging" that enables installation of aluminum accessories without the need of a welder. These Swage products allow the electric utility to install accessories faster and more efficiently, lowering installation costs. Swaging is the ideal solution for areas with shortages on qualified welders or when inclement weather conditions prohibit installation.

Swage Tooling is available for:

  • Bus—1” through 6”
  • Cable—336.4 MCM AAC/ACSR conductor through 3500 MCM AAC/ACSR conductor
  • Grounding—#6 conductor to 1000 MCM conductor

Testing Lab and Engineering Support

AFL’s accessory products are manufactured in Duncan, SC, in our facility that is certified to ISO 14001 and ISO 9001:2008 standards. With 10,000 sq. ft. of open testing space, our substation accessories are designed and tested to meet ANSI/NEMA CCA standards for performance, installation and operation. The test lab allows AFL engineers to perform testing for strength, vibration, fatigue, heat rise, current cycle, insulator and flashover.


For all your substation needs, AFL provides engineering support including:

  • Direct line to Engineering in the office for any technical inquiries +1 (800) 890-8878
  • Custom parts for any voltage, welded, bolted, Swage or standard compression
  • Ability to 3D print tooling for quick lead times and reduced cost
  • Free on-site training regardless of type of power connector used
