Ultra Flexible ROV Tether

Custom Neutral Buoyancy ROV Cables


Ultra Flexible ROV Tether Cable is a specialized underwater cable designed for ROV, AUV, and underwater monitoring applications that require exceptional flexibility, neutral buoyancy, and reliable performance during continuous deployment and recovery operations. The flexible construction allows the cable to withstand repeated bending, towing, and movement caused by underwater currents, making it suitable for long-term operation in both seawater and freshwater environments.

Key Features

Floating Capability: Engineered with a specific gravity close to that of the operating medium (freshwater: 1.0 g/cm³ / seawater: 1.02–1.03 g/cm³).

Tensile Strength: Standard tensile load range of 200 kg to 500 kg, with custom options available up to 1000 kg or higher.

Signal Transmission: Features an 8-core configuration (typically 4 twisted pairs) that supports Ethernet protocols for industrial data transmission requirements.

Dynamic Flexibility: Designed with a dynamic bend radius of 5D to 8D and a flex life of 5 to 10 million cycles, making it suitable for drum winches and high-frequency bending applications.

Test Equipment

Industrial cables manufactured by RouLine are inspected using dedicated equipment for electrical, mechanical, and environmental testing. Depending on the cable design, testing may include high-voltage testing, insulation and continuity checks, tensile testing, flexing, temperature-humidity, salt-spray, and dimensional inspection. Testing procedures can be defined according to cable construction, operating depth, voltage rating, mechanical requirements, and applicable standards.  →View the Test Equipment in Use
