1. Flexible design and easy maintenance: The flat cable adopts a flexible design, which is easy to bend and arrange, and adapts to complex submarine terrain. Its structure is simple, maintenance is convenient, and maintenance costs are reduced.
2. Water pressure and corrosion resistance: The central beam tube design enables the flat cable to resist high water pressure and seawater corrosion, ensuring stable transmission of signals and power in harsh marine environments.
3. High power transmission efficiency: The flat cable uses efficient conductive materials inside, which can provide stable power transmission efficiency and meet the high requirements of coastal and submarine projects for power demand.
4. High reliability: After strict testing and quality control, the central beam tube flat cable has high reliability and stability, can operate safely for a long time, and ensure the successful implementation of marine projects.
Note: The outer sheath material, color and printing information of the optical cable can be customized according to the requirements of customers
