2500kN High-Force Hydraulic Compressor for Large Conductors & EHV/UHV Terminals

2500kN High-Force Hydraulic Compressor: Unrivaled Power for the Toughest Conductor & Terminal Connections in EHV/UHV Systems

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we understand that the increasing current capacities and extreme mechanical stresses of modern Extra-High Voltage (EHV) and Ultra-High Voltage (UHV) transmission lines demand connection solutions of unprecedented power and precision. Our 2500kN High-Force Hydraulic Compressor for Large Conductors & EHV/UHV Terminals is the pinnacle of conductor compression technology, specifically engineered to deliver an immense 2500 kilonewtons (equivalent to 250 tons) of force. This formidable power ensures flawless, high-integrity "cold weld" connections on the largest conductors, heaviest earthwires, and most critical bi-metallic (Cupreous-aluminous) terminals found in the most demanding power infrastructure projects globally. As a prominent China manufacturer and exporter specializing in comprehensive one-stop supply for both overhead transmission line (OHTL) wire cable conductor tension stringing equipment and underground cable laying equipment, this powerful hydraulic compressor exemplifies our unwavering commitment to providing innovative, supremely durable, and highly effective equipment that ensures superior safety, efficiency, and the long-term, unyielding performance of your most vital electrical connections.

This 2500kN Hydraulic Compressor is designed for applications where standard hydraulic crimpers simply cannot deliver the necessary force or accommodate the sheer size of the components. Its colossal compression capability ensures a perfect, void-free connection across the entire crimp area, even on conductors with very large cross-sectional areas or rigid strand configurations common in EHV/UHV applications. This immense, controlled hydraulic pressure is critical for achieving optimal metal flow and molecular bonding, resulting in connections with minimal electrical resistance, maximum current carrying capacity, and exceptional mechanical strength – often exceeding the breaking strength of the conductor itself. The tool's versatility extends to compressing specialized terminals on large overhead conductors (e.g., multi-bundle ACSR, ACAR), heavy-gauge earthwires (including OPGW), and particularly challenging cupreous-aluminous (bi-metallic) terminals that facilitate a robust, corrosion-resistant transition between dissimilar metals in high-current applications. Investing in this high-force compressor is paramount for utilities and contractors involved in constructing and maintaining large-scale power infrastructure, where connection integrity is non-negotiable for system reliability and safety.
