Hydraulic Earthwire Puller: Precision & Power for Overhead Ground cable stringing

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we understand that the installation of "earthground cable" (also known as earthwire or grounding cable) is a critical phase in the construction of any overhead transmission line. The safety and integrity of the entire power system depend on its flawless and secure installation. Our Hydraulic Earthwire Puller for Overhead transmission lines is a high-performance "hydraulic transmission cable puller" meticulously engineered "to string earthground cable" with unparalleled control, power, and safety. The use of an advanced hydraulic transmission system ensures a smooth and consistent pulling force, which is essential for protecting the integrity of the earthwire and associated components over long distances. As a prominent China manufacturer and exporter specializing in comprehensive one-stop supply and services for both overhead transmission line (OHTL) wire cable conductor tension stringing equipment and underground cable laying equipment, this hydraulic earthwire puller exemplifies our unwavering commitment to providing innovative, durable, and highly efficient solutions that are critical for building safe and reliable power infrastructure.

The Hydraulic Earthwire Puller is a specialized piece of machinery designed for the stringing of earthwire, or in many modern cases, Optical Ground Wire (OPGW), which combines the function of a ground wire with a fiber optic communication link. The "hydraulic transmission" is the key to its superior performance. A diesel engine powers a hydraulic pump, which in turn drives the capstan or bull wheels. This closed hydraulic circuit provides several critical advantages:

  • Infinitely Variable Speed Control: Operators can precisely adjust the pulling speed in both directions, which is crucial for managing tension and navigating complex terrain.

  • Tension Control: The hydraulic system allows for the maximum pulling tension to be preset, with a line pull gauge providing real-time feedback. This prevents over-tensioning, which could damage the earthwire, poles, or towers.

  • Automatic Overload Protection: In the event that the pulling force exceeds the preset limit, the system automatically disengages or stops, providing a vital safety feature.

  • Smooth Operation: The hydraulic system ensures a jerk-free, continuous pull, which is essential for the smooth handling of sensitive OPGW cables.

This "hydraulic transmission cable puller" is typically a standalone, towable unit with a rigid axle and a self-loading reel winder, making it highly mobile and efficient for deployment along the transmission line route. By deploying Ningbo Changshi's Hydraulic Earthwire Puller, you equip your team with a specialized, high-performance tool that guarantees the safe, efficient, and damage-free installation of this critical component of your power infrastructure.

Product Features & Benefits:

  • Hydraulic Transmission System: Provides superior power, precise speed control, and automatic overload protection, ensuring a smooth and safe "stringing earthground cable" operation.

  • Dedicated for Earthwire/OPGW: Specifically engineered for the unique requirements of pulling ground cables and sensitive OPGW, protecting them from damage during installation.

  • Variable Pulling Speed: Offers infinitely variable speed control in both forward and reverse directions, allowing operators to adapt to different terrain and installation requirements.

  • Real-Time Tension Monitoring: Equipped with a line pull gauge to provide continuous, accurate tension readings, and an automatic over-pulling protection system for maximum safety.

  • High-Capacity & Robust Construction: Built with heavy-duty steel and durable components to handle long-distance stringing and withstand the rigors of field work.

  • Integrated Reel Winder: Includes a self-loading reel winder with an automatic level wind mechanism, simplifying the handling of the earthwire drum.

  • Enhanced Safety: The hydraulic brake system automatically activates in case of hydraulic failure, ensuring the cable remains secure.

  • Efficient & Mobile: Designed as a towable unit with a rigid axle, making it easy to transport and deploy along the transmission line route.

  • Versatile Application: While primarily for earthwire, its precise control makes it suitable for other pilot wire or single OHTLstringingequipment.com/Conductor-Stringing-Equipment.html target='_blank'>conductor stringing applications.

  • High-Quality Components: Features internationally recognized hydraulic pumps, motors, and diesel engines for maximum reliability and performance.

Product Applications:

Our Hydraulic Earthwire Puller is an indispensable tool for the safe and efficient stringing of overhead transmission lines:

  • Earthwire/Ground cable installation: The primary application for pulling conventional steel earthwire or ground cables along overhead power line towers.

  • OPGW (Optical Ground Wire) Stringing: Ideal for the highly sensitive installation of OPGW, where precise tension control is critical to protect the fiber optic core.

  • Overhead Transmission Line Pilot Rope Pulling: Can be used to pull a pilot rope, which is then used to pull the main conductors.

  • Conductor Re-stringing: Assists in the replacement of old conductors or earthwires with new ones.

  • Any Project Requiring Controlled Overhead Pulling: Applicable wherever a powerful yet precise pulling force is needed for overhead conductor or cable stringing.
