Full Tension Compression Splice
A compression splice is a high-strength electrical connector used in overhead and underground power line construction to permanently join two conductors. It operates by applying controlled mechanical compression—typically using hydraulic crimping tools—to create a low-resistance, high-integrity bond between conductor strands. This ensures efficient current transfer, mechanical continuity, and long-term reliability under varying load and environmental conditions.
Engineered for compatibility with aluminum, copper, or ACSR conductors, compression splices are widely deployed in transmission and distribution networks where joint performance is critical to system stability and safety.
