The answer is STP (Shielded Twisted Pair) cables
.
Compared to Unshielded Twisted Pair, STP offers additional safeguards against Electromagnetic interference (EMI) and crosstalk. While UTP reduces some EMI, STP cables effectively block interference and ensure high-speed performance. STP cables have a metallic foil that cancels out electromagnetic interference. They are the preferred cables that protect against high-level EMI from, power lines, radar systems, or electromagnetic fields

Mine headgear constructions support wheel mechanisms for suspending winding cables that transport workers and ore up and down deep level shafts. These strange anthropomorphic structures have become the iconic symbol for mining.
