Two-Conductor Bundle Live Line Cart for OHTL Inspection

Two-Conductor Bundle Live Line Cart: Essential for Safe and Efficient Maintenance of Bundled Overhead transmission lines

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we understand that maintaining the integrity and performance of high-voltage overhead transmission lines (OHTL) is paramount, especially for complex bundled conductor systems that are prone to wear and require diligent inspection. Our Two-Conductor Bundle Live Line Cart is a highly specialized and indispensable tool, expertly engineered to enable safe, efficient, and thorough inspection and minor repair work on energized two-conductor bundled transmission lines. This purpose-built cart allows maintenance personnel to traverse directly along the energized lines, providing unparalleled access to critical components without the need for de-energizing the circuit. 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 Two-Conductor Bundle Live Line Cart exemplifies our unwavering commitment to providing innovative, durable, and highly effective equipment that ensures superior safety, productivity, and operational continuity on your most critical and demanding OHTL maintenance operations.

The Two-Conductor Bundle Live Line Cart is specifically designed to fit securely over and navigate along two parallel conductors that form a single phase in a bundled configuration. Constructed from robust, non-conductive, and highly durable materials, the cart features precision-engineered rollers or wheels that smoothly glide along the conductors, allowing linemen to perform close-up inspections of conductors, spacers, clamps, insulators, and other hardware. The "live line" capability signifies that the cart and its operators are bonded to the energized conductor, working at potential, which requires stringent safety protocols and specialized training. This method dramatically reduces outage times and associated economic losses, as maintenance can proceed without interrupting power supply to customers. The cart provides a stable and secure platform, enhancing worker safety and efficiency when performing tasks such as visual inspections for damage, checking conductor sag, identifying corona issues, replacing minor components, or applying specialized coatings. Its ergonomic design and ease of maneuverability make it an essential tool for proactive maintenance, ensuring the long-term reliability and optimal performance of bundled high-voltage transmission lines.

Product Features & Benefits:

• Specifically Designed for 2-Conductor Bundles: Precision-engineered to fit and smoothly traverse transmission lines with a two-conductor bundle per phase, ensuring optimal stability and access.

• Live Line Operation Capability: Enables safe access and work on energized conductors (at potential), significantly reducing downtime, minimizing economic losses, and eliminating the need for planned outages.

• Enhanced Safety Features: Constructed with high-quality insulating materials, integrated bonding points, emergency braking systems, and ergonomic safety harnesses/tie-off points to ensure maximum worker protection.

• Durable & Robust Construction: Built from high-strength, weather-resistant materials to withstand harsh environmental conditions and rigorous daily use in demanding field operations.

• Smooth & Stable Movement: Precision wheels/rollers and balanced design ensure stable, low-friction movement along conductors, allowing linemen to work efficiently and comfortably.

• Optimized Access for Inspection & Repair: Provides close-up, hands-on access to conductors, spacers, vibration dampers, clamps, insulators, and other components for thorough visual inspection and minor repairs.

• Increased Operational Efficiency: Reduces the time and cost associated with line maintenance by eliminating the need for de-energization, scaffolding, or helicopter-assisted access for many tasks.

• Lightweight & Portable Design: Designed for relatively easy transport and deployment by ground crews to tower locations, then hoisted onto the lines.

Product Applications:

Our Two-Conductor Bundle Live Line Cart is an indispensable tool for maintaining the reliability and performance of high-voltage transmission infrastructure:

• Routine Inspections of Bundled Conductors: Essential for regular visual inspection of conductors, conductor bundle spacers, and related hardware for wear, damage, corrosion, or looseness.

• Corona & Arcing Detection: Allows close proximity inspection to identify and assess sources of corona discharge and arcing, crucial for reducing power losses and radio interference.

• Vibration Damper Inspection & Replacement: Enables easy access to check the condition of vibration dampers and replace damaged ones without de-energizing the line.

• Spacer & Clamp Maintenance: Facilitates inspection, tightening, or replacement of conductor bundle spacers and clamps.

• Conductor Sag & Tension Monitoring: Provides a platform for accurate visual assessment of conductor sag and tension, aiding in proactive maintenance planning.

• Minor Conductor Repair: For patching minor conductor damage, applying specialized coatings, or performing other small repairs on energized lines.

• Live Line Tool & Equipment Transport: Can be used to transport live-line tools, spare parts, and other equipment along the bundle for on-site work.

• Pre-commissioning Inspections: Final inspection of newly strung bundled lines before full energization.
