High-performance Tethered Cable For Aerostats PDK41904-2×1.2

This product is a multi-functional tether cable specifically designed for aerostats (such as tethered balloons, airships, high-altitude observation platforms, etc.), integrating high-strength mechanical bearing capacity and stable power transmission.

The cable body adopts a dual-line composite structure, with excellent tensile performance (breaking force ≥ 200kg) and the ability to output a rated current (7-10A).

It can simultaneously meet the needs of tethering and fixing aerostats, powering high-altitude equipment, and signal transmission.

It is an ideal choice for fields such as meteorological monitoring, communication relay, and security monitoring.

Advantages and Technical Features

Tensile Reinforcement Layer: The outer layer of the conductor is covered with a high-strength aramid fiber braided layer. The breaking force is as high as 200kg, and it has both flexibility and impact resistance, which can cope with complex environments such as strong winds and sudden changes in load.

Environmental Adaptability-Weather-resistant Sheath: The outer layer is made of UV-resistant modified polyurethane (TPU) material, which has the characteristics of wear resistance, corrosion resistance, and resistance to high and low temperatures (-40℃ to +105℃), and is suitable for harsh climates such as the ocean, desert, and high altitude.

Lightweight Design: The cable body has a small diameter (5.4±0.3mm) and is light in weight (31±0.5g/m), minimizing the impact on the lifting force of the aerostat.

Multi-functional Integration- Signal transmission channels can be optionally reserved (such as optical fiber or coaxial structure), supporting the integration of power and data in one cable, simplifying the complexity of the wiring of the aerostat system.

 

Typical Application Scenarios

Meteorological and Environmental Monitoring: Tethered balloons carry meteorological sensors and cameras to collect data such as high-altitude temperature and humidity, wind speed, and air quality in real time.

Emergency Communication and Security: Tethered platforms are quickly deployed at the disaster site to provide temporary communication base stations or high-definition monitoring coverage.

Scientific Research and Military: Special tasks such as high-altitude optical observation, electronic reconnaissance, and target drone towing.

Commercial Applications: Power supply and fixing of aerial devices such as advertising balloons and light shows.

 

Usage and Maintenance Suggestions

Installation Specification: Ensure that special shackles or anti-wear sheaths are used at the connection points of the cable with the aerostat and the ground fixed end to avoid excessive bending.

Regular Inspection: It is recommended to check the surface wear of the cable body, the conductivity of the conductor, and the tightness of the joints every quarter. In harsh environments, the inspection cycle should be shortened.

Safety Warning: Overloading is strictly prohibited (the safety factor of the breaking force is recommended to be ≥ 3 times the working load), and avoid the superposition of the full-load current and the ultimate tensile force at the same time.
