250kN Hydraulic Compression Tool for Overhead & Grounding Connections

250kN Hydraulic Compression Tool: Reliable & Efficient Connections for overhead lines & Grounding Systems

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we understand that the long-term reliability and safety of power transmission and distribution networks are built upon the strength and integrity of every connection. A precisely crimped connection is fundamental to preventing power losses, minimizing maintenance, and ensuring grid stability. Our 250kN Hydraulic Compression Tool for Overhead & Grounding Connections is a versatile and robust solution, expertly engineered to deliver a powerful 250 kilonewtons (equivalent to 25 tons) of force. This ensures consistent, high-quality "cold weld" connections on a wide range of conductors, earthwires, and critical bi-metallic (Cupreous-aluminous) terminals, making it an indispensable tool for routine power line construction and maintenance. 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 250kN hydraulic compression tool exemplifies our unwavering commitment to providing innovative, durable, and highly effective equipment that ensures superior safety, efficiency, and the long-term performance of your electrical infrastructure.

This 250kN Hydraulic Compression Tool is engineered for a broad spectrum of power line applications, providing the ideal balance of power and portability. Its robust hydraulic system ensures that the necessary, consistent pressure is applied to compression-type fittings, ensuring optimal metal-to-metal contact and eliminating voids. This process is crucial for establishing low-resistance electrical paths and creating mechanically strong joints on mainline overhead conductors (including ACSR, AAAC, AAC), various types of earthwires (overhead ground wires, counterpoise wires), and particularly important cupreous-aluminous (bi-metallic) terminals. Bi-metallic connectors are vital for safely and effectively transitioning between copper and aluminum conductors without creating galvanic corrosion, ensuring connection longevity. The tool's design prioritizes ease of use and reliability in the field, making it a go-to choice for line crews. Whether you are installing new lines, making repairs, or upgrading connections, this 250kN Hydraulic Compressor provides the confidence of a durable, high-conductivity connection that will withstand environmental stresses and ensure the uninterrupted flow of power.
