Quick answer: TDC is a lightweight tether cable for tethered drones and airborne platforms, available as power-only, hybrid power + single-mode fibre, or coaxial. 750–1500 VDC rated, tunable tensile strength up to 6000 kg, 100 m MOQ.
Three builds, one job: keep the aircraft flying
- Power types — 2 to 8 cores, AWG or mm² conductors, 750–1500 VDC, from 8.5 g/m.
- Hybrid types — power cores plus 1–6 single-mode fibre (G.657A2) for high-bandwidth data.
- Coaxial types — 0.35–0.8 mm² coax for RF / video payloads.
- Low weight is the design goal — every gram is payload lost, so the jacket is thin and the copper optimised.
- Tensile rating selectable — from 20 kg to 6000 kg depending on the platform and wind load.
Typical applications
Tethered drones for 24-hour area lighting, persistent surveillance, telecom relay, emergency communications, aerial inspection, and airborne sensor platforms that need continuous power and data.

Frequently asked questions
- How much does a tether UAV cable weigh?
- TDC tether cables start around 8.5 g/m for 2 × 0.2 mm² power types; hybrid and high-current builds are naturally heavier, so the design is matched to the aircraft's payload budget.
- Can the tether carry fibre as well as power?
- Yes. Hybrid models combine 2–8 power cores with 1–6 single-mode fibre cores (G.657A2 bend-insensitive) in one cable.
- What tensile strength can the tether be made to?
- Tensile rating is selectable — from roughly 20 kg for small coax types up to 6000 kg for reinforced hybrid builds.
