Application
Designed for use as trailing cables on AC mining
equipment:
- Where a ground-check conductor is required
for fail-safe monitoring
- With Bretby-type cable handling devices on
longwall shearers
- Where induced voltages in the grounding
system will not produce a hazard
- On low- and medium-voltage AC circuits
where shielding is desired or required
