In the past, three separate compression accessory series were required to connect ACSR, AAC, AAAC and ACAR. To assist utilities and distributors in reducing inventory, AFL designed one series of compression accessories that can handle all four conductor types, the Quick Compress® product line. Quick Compress handles these conductors while maintaining the same mechanical and electrical reliability as other AFL product lines.
There are two primary characteristics that make Quick Compress different from any other accessory line. First, it is made of a high strength aluminum alloy, which has a minimum tensile strength nearly twice that of other compression accessory systems. This means that for the same conductor size, smaller connectors can be used without any fear of sacrifi cing strength.
Secondly, Quick Compress uses an aluminum ‘core grip’ to hold the steel core of ACSR. This eliminates the need to have a dead end steel compression barrel or a steel sleeve for full tension ACSR joints. By eliminating the steel, only one set of dies is required for installing Quick Compress Accessories.
All compression accessories are designed to operate at a temperature 15-25% cooler than the conductor. Standard compression accessories are designed for conductor operating temperatures up to 100ºC (212ºF). For applications exceeding 100ºC (212ºF) operating temperature, see the HiTemp® Compression Accessories.
