PDK41302-7*0.5 UAV Tethering Cable – 7-Core 0.5mm² Tinned Copper, FEP Insulation & Jacket, LCP Braid, 200KG Tensile, 70g/m, For Drone & Aerostat Systems

This PDK41302 UAV tethering cable is specifically engineered for unmanned aerial systems, multirotor drones, and aerostat platforms that demand a lightweight, high‑strength, and weather‑resistant umbilical for power and multi‑channel signal transmission. It integrates seven 0.5 mm² (approx. AWG 20) stranded tinned copper conductors – a versatile configuration well‑suited for distributing DC power (e.g., 24‑48 V) to propulsion motors, cameras, gimbals, and sensors, while also carrying telemetry, video, or control signals over multiple circuits.

All conductors are tinned for superior corrosion resistance in outdoor and humid environments. FEP (Fluorinated Ethylene Propylene) serves as both the primary insulation on each conductor and the outer jacket, offering exceptional thermal stability (-65°C to +150°C), negligible moisture absorption, inherent flame retardancy (VW‑1), and resistance to fuels, oils, and chemicals. The cable is reinforced with an LCP (Liquid Crystal Polymer) braid – a high‑strength, low‑creep, ultra‑low‑moisture‑absorption material that provides a 200 kg breaking strength, enabling secure tethering in moderate wind conditions and safe recovery operations. Thanks to the low‑density FEP and LCP materials, the cable achieves an ultra‑light weight of just 70 grams per meter, maximizing flight time, payload capacity, and maneuverability. The FEP jacket and LCP braid combination also offers outstanding abrasion, cut, and UV resistance, ensuring long‑term durability in outdoor field operations. This cable is ideal for persistent surveillance, communications relays, inspection, and military missions – where reliable multi‑circuit transmission, high strength‑to‑weight ratio, and environmental toughness are critical.

 

Key Features – Tinned Copper, FEP Insulation & Jacket, LCP Braid, 200KG Tensile, 70g/m

Tinned copper conductors (7×0.5 mm²) – seven stranded tinned copper cores for efficient power distribution (up to 4‑5 A per core) and multi‑channel signal transmission; tinning protects against corrosion and ensures long‑term reliability.

FEP insulation – rated -65°C to +150°C; offers ultra‑low moisture absorption, excellent dielectric strength, and resistance to fuels, oils, and chemicals – maintaining signal integrity and power stability.

FEP outer jacket – same high‑performance material as the insulation, providing a seamless, highly durable outer layer that resists UV, ozone, and environmental stress; inherently flame‑retardant and self‑extinguishing.

LCP braid reinforcement – high‑modulus liquid crystal polymer braid delivers 200 kg breaking strength with minimal creep and ultra‑low moisture absorption (0.04%), enhancing pull resistance without adding significant weight.

Ultra‑lightweight (70 g/m) – optimized material selection (FEP + LCP) keeps cable mass exceptionally low, increasing drone flight endurance and payload capability.

Flexible and manageable – despite the high tensile rating, the cable remains flexible for easy spooling, deployment, and storage.

 

Ideal For

Long‑endurance tethered drones for surveillance, border patrol, and disaster response

Military UAVs and tactical aerostats requiring lightweight, high‑strength tether with multi‑circuit power/signal

Broadcasting and live‑event camera drones needing reliable power and video/control over a single tether

Industrial inspection UAVs (power lines, wind turbines, pipelines) where weight and durability are key

Search and rescue drones with real‑time video and sensor telemetry

Any tethered aerial platform demanding a 7‑conductor 0.5 mm² cable + 200 kg tensile + ultra‑light 70 g/m

 

Conclusion

This PDK41302‑7*0.5 UAV tethering cable delivers an optimal balance of power capacity, signal versatility, mechanical strength, and ultra‑lightweight construction. The integration of tinned copper conductors, FEP insulation and jacket, LCP braid, and a 200 kg tensile rating ensures reliable, durable, and high‑performance operation in demanding flight environments. At just 70 g/m, it is an ideal solution for advanced UAV systems, military observation, and commercial aerial platforms.
