    100A Grounding Block: Triple Sheave Conductor Stringing Pulley for Induced Electricity Removal

    100A Grounding Block: Triple Sheave Conductor Stringing Pulley for Induced Electricity Removal
    Product Overview

    The SJL series Grounding Block is a critical safety component used in overhead line stringing operations. Its primary function is to eliminate induced electricity from conductors or earth wires, protecting both personnel and equipment. Featuring a triple sheave mechanism, the block is automatically compacted against the wire by a precision torsion spring, ensuring continuous electrical contact even during high-speed pulling.

    Technical Specifications

    Our grounding blocks are engineered to handle high-current transients with the following verified parameters:

    Item NumberModelApplicable ConductorBottom DiameterMax Current (A)Weight (kg)
    12101SJL38-100Φ38 ConductorΦ46 mm100 A8.9 kg
    12101ASJL48-100Φ48 ConductorΦ56 mm100 A10.0 kg
    12102SJT38-100Φ38 Steel Wire RopeΦ46 mm100 A11.0 kg
    • Transit Time: ≤ 0.1 second
    • Supporting Earth Wire Sectional Area: 25 mm² (Recommended)
    • Sheave Material: High-strength Casting Steel or Aluminum
    Key Technical Advantages
    • Triple Sheave Contact System: Ensures a stable, multi-point connection with the conductor to maximize conductivity and minimize sparking.
    • High Current Capacity: Rated for a maximum allowable current of 100A, providing a robust safety margin during short-circuit or high-induction events.
    • Automatic Torsion Spring Compaction: Eliminates manual adjustment by using a spring-loaded system that maintains constant pressure on the moving conductor.
    • Rapid Discharge Response: Features a transit time of only 0.1 seconds, ensuring instantaneous grounding protection.
    Applications
    • Overhead Line Stringing: Mounting on the outlet side of tensioners or the inlet side of pullers.
    • Induced Current Mitigation: Essential for working in proximity to energized parallel transmission lines.
    • Power Utility Construction: Safe installation of ACSR conductors and steel grounding wires.
    Professional Buyer FAQ
    Q1: Where is the best position to install the grounding block during stringing?

    It is recommended to mount the block on the outlet side of the tensioner or the inlet side of the puller, secured by two stay wires for maximum stability.

    Q2: Can this block handle different conductor diameters?

    Yes. We offer models specifically for Φ38 and Φ48 conductors. The SJL48-100 is specifically designed for larger Φ48 conductor stringing.

    Q3: Why is the 0.1s transit time significant?

    The 0.1s response time ensures that any surge or induced charge is redirected to the ground almost instantaneously, preventing the build-up of dangerous voltage levels.
