Teck Cables were originally developed for use in mines, but they are now widely used in commercial buildings, as well as in primary and secondary industries, chemical plants, refineries and factory environments. They are flexible, resistant to mechanical abuse, corrosion resistant, and compact.

Copper Medium-Voltage Power Cables, describes the use of Teck Cables for systems 5 kV and above. The Teck Cables used in industrial and commercial buildings are smaller, and may have ratings of 600 or 1000 volts. A modified Teck Cable construction is available for vertical installations, such as in high-rise buildings or mine shafts, where the armour is locked-in-place to prevent slippage of the inner core.

The single-conductor 1000-volt Teck Cables (Figure 8) include a cable construction with concentric bonding (grounding), which is bare or tin-coated copper wires wound helically over the insulation, followed by an extruded layer of PVC before the armour is applied.
