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.
Our grounding blocks are engineered to handle high-current transients with the following verified parameters:
| Item Number | Model | Applicable Conductor | Bottom Diameter | Max Current (A) | Weight (kg) |
|---|---|---|---|---|---|
| 12101 | SJL38-100 | Φ38 Conductor | Φ46 mm | 100 A | 8.9 kg |
| 12101A | SJL48-100 | Φ48 Conductor | Φ56 mm | 100 A | 10.0 kg |
| 12102 | SJT38-100 | Φ38 Steel Wire Rope | Φ46 mm | 100 A | 11.0 kg |
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.
Yes. We offer models specifically for Φ38 and Φ48 conductors. The SJL48-100 is specifically designed for larger Φ48 conductor stringing.
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.
