Adjustable Earthwire Spreading Block for OHTL Ground Wire Installation

Adjustable Earthwire Spreading Block for Precise Overhead transmission line (OHTL) Ground Wire Installation

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we understand the critical role of ground wires (earthwires) in ensuring the safety and lightning protection of overhead transmission lines (OHTL). Our Adjustable Earthwire Spreading Block is a specialized, precision-engineered tool designed to facilitate the accurate spacing and smooth installation of earthwires during overhead line construction and maintenance. As a prominent China manufacturer and exporter, we offer a comprehensive one-stop supply for a wide array of tools and equipment for power lines, and this adjustable block exemplifies our commitment to precise control, operational efficiency, and enhanced safety in every aspect of OHTL projects.

Earthwires, also known as ground wires or shield wires, are typically installed above the power conductors to protect the line from lightning strikes. Their correct spacing and tensioning are vital. This adjustable block provides a controlled method for guiding and spreading multiple earthwires, or managing the distance between an earthwire and power conductor, ensuring proper clearances and preventing tangling or damage. Its adjustability allows for adaptability to various tower configurations and spacing requirements, making it an indispensable tool for achieving compliant and robust grounding systems.

Product Features & Benefits:

• Precise Earthwire Spreading/Guidance: Designed with adjustable arms or roller positions to accurately control the spacing and path of earthwires, ensuring proper separation from power conductors and each other.

• Optimal Ground Wire Protection: Features smooth, non-abrasive rollers or contact surfaces, often lined with materials like UMC (polyurethane) or durable nylon, which protect the earthwire from scratching, kinking, or other damage during installation.

• Adjustable Versatility: The key feature is its adjustability, allowing for quick modification of the distance between wires or the block's mounting configuration to suit different tower designs, span lengths, and project specifications.

• Robust & Durable Construction: Manufactured from high-strength galvanized steel or robust aluminum alloys, built to withstand the rigors of field use and harsh environmental conditions, ensuring extended service life and reliable performance.

• Smooth Operation: Equipped with quality bearings or low-friction surfaces on the rollers, ensuring smooth movement of the earthwire through the block, reducing pulling effort and potential for snags.

• Secure Mounting: Designed for stable and secure attachment to tower structures, cross-arms, or suspension points, providing reliable support during the earthwire stringing process.

• Corrosion Resistance: All exposed components are typically hot-dip galvanized or treated with durable coatings, providing excellent protection against rust and environmental degradation.

Product Applications:

Our Adjustable Earthwire Spreading Blocks are essential for various aspects of overhead transmission line projects involving ground wires:

• New OHTL Construction: Critical for the initial installation and accurate spacing of single or multiple earthwires above power conductors.

• OPGW Installation: Can be used to guide OPGW (Optical Ground Wire) where precise spacing relative to other wires is needed.

• Line Upgrades & Re-stringing: Ideal for replacing or adding earthwires to existing lines, ensuring proper clearances are maintained.

• Angle Tower & Specialty Structure Applications: Provides flexibility for guiding earthwires around complex tower designs or unique span configurations.

• Substation & Entry/Exit Point Management: Helps maintain controlled spacing of earthwires as they approach and depart from substation infrastructure.

• Maintenance & Repair: Useful for controlling earthwires during repair work or adjustments.
