Tension grab drum cables are purpose-built flexible power cables for cable drum systems that must operate under tensile loads while winding and unwinding — common in vertical lift applications, deep well pump systems, and subsea winch operations where the cable must bear its own weight plus the weight of connected equipment. These cables incorporate integrated high-tensile steel wire or fibre strain relief elements that absorb the tensile load, preventing stress transfer to the copper conductors.
Available in high-temperature variants (up to +125°C) for furnace, foundry, and kiln applications, and low-temperature grades (down to ‑60°C) for Arctic outdoor equipment and cold store installations. Rated 0.6/1 kV to 3.6/6 kV; 3 to 4 power cores; cross-sections 1.5 mm² to 70 mm².

Standard reeling cables are not designed to bear axial tensile loads. Tension grab drum cables transfer all mechanical load to the integrated strain relief element, protecting the electrical conductors and ensuring long service life.
Specify the maximum ambient temperature at the drum and at the connected equipment, plus the minimum cold-start temperature. For applications spanning more than 100°C range, consult our engineers for a custom construction recommendation.
