The Challenge with Conventional Crimping
While Advanced Conductor Composite Core (ACCC) technology offers unprecedented power capacity, installing high-capacity conductors requires specialized accessories. Conventional conductors rely on hydraulic compression dies that exert up to 100 tons of force. While effective for steel, applying multi-directional hexagonal compression to brittle carbon fiber cores causes notch effects, point-loading stresses, and risk of crushing the core.
The Mechanical Solution: Collet & Housing Mechanism
Presented by Mosdorfer (a 300-year-old Austria-founded fitting manufacturer established in 1712), the specialized Collet and Housing System solves core crushing issues through precision engineering:
- 360 Degree Uniform Radial Pressure: Precision-machined austenitic stainless steel collets grip the exposed carbon core evenly around its full circumference.
- Self-Energizing Wedge Action: Tensile pull forces convert directly into coaxial clamping pressure. The higher the line tension, the tighter the grip, eliminating slippage without damaging fibers.
- Indirect Aluminum Compression: Electrical current transfer is handled independently via a heavy-duty outer aluminum sleeve, ensuring mechanical load holding and electrical conductivity are cleanly separated.
Live Demo: InfoCore Field Verification
The live demonstration highlighted InfoCore technology. Fiber optic channels embedded in each quadrant of the carbon core transmit visible light. Field installers shine light through dead-ends and midspan joints to visually confirm that no micro-fractures occurred during stringing or joint assembly.
Key Takeaways
High-tech conductors demand high-precision hardware. Utilizing self-locking collet systems ensures installation repeatability, long-term fatigue resistance, and total protection for composite core conductors.
