The ACCC® Collet & Housing System is a purpose-built termination solution designed specifically for composite core conductors. Unlike traditional compression hardware, it delivers high mechanical strength without inducing core damage—ensuring long-term reliability under real-world operating conditions.
Traditional dead-end fittings rely on direct compression or swaging, creating localized pressure points and linear strain on the conductor core.
For composite cores, this can result in:
These failure modes are inherent to hardware originally designed for steel cores—not composite materials.
The Collet and Housing System replaces compression with a tapered, self-energizing grip that applies uniform radial pressure along the core.
This eliminates damaging stress concentrations and delivers:
Uniform load distribution prevents crack initiation and maintains full composite strength throughout the lifecycle.
Engineered grip provides strong holding force while eliminating the failure modes seen in compression systems.
Accommodates differential expansion between aluminum and composite materials without inducing stress or separation.
Self-centering design removes installation variability—delivering predictable performance across crews and projects.
Maintains performance under wind, ice, thermal cycling, and high-temperature operation typical of Advanced Conductors.
The ACCC® Collet & Housing System is not an adaptation—it is a fundamental redesign of how composite core conductors are terminated.
By eliminating compression-induced damage and replacing it with controlled radial engagement, it ensures:
On the basis of four clamp body sizes and the cor-responding wedge pairs, conductor diameters of 14.1 mm to 43.0 mm with SMFL values of more than 300 kN can be covered – a clear savings potential regarding storage and logistics costs.
Special attention was paid to the strength properties, the stress dis-tribution inside the clamp body and the forging process.
Dedicated Advanced fittings (Dead End Clamp) with Swage Drawing Technology (SDT) is Reliable and less susceptible to human errors.
More Conductor Holding Area ensures reliability.
No Direct Crimping and hence, no strain on Composite Core
Single Swaging process facilitates Quick and easy
installation leads to 75% Time Saving on installation.
Compact and Optimized Design helps in easy handling for installation and reduces the overall component weight in the network, avoiding strain on Poles.
