Products Description
- AD8 water resistance: Designed for photovoltaic cable routes exposed to prolonged moisture and wet operating environments.
- High DC voltage capability: Suitable for modern solar arrays with rated voltages of 1,000 or 1,500 V DC.
- Flexible tinned-copper conductor: Class 5 stranded construction supports installation on floating platforms and cable routes subject to movement.
- Cross-linked insulation system: Electron-beam cross-linked polyolefin insulation and sheath provide heat, weather and mechanical resistance.
- Wide operating-temperature range: Performs in ambient and installation conditions from -40°C to +120°C within the cable's application limits.
- Outdoor durability: Resistant to UV exposure, humidity and demanding climates found on reservoirs, coastlines, rooftops and open solar fields.
- Low-halogen fire performance: Supports flame non-propagation and controlled acidity/conductivity of combustion gases.
- Optional protection: Rodent-resistant and termite-resistant constructions, along with metre-by-metre marking, are available for project-specific cable routes

Typical Applications
- Floating PV power plants: Connects modules, strings and DC equipment installed on floating platforms across reservoirs, lakes and water-treatment ponds.
- Lakeside and reservoir solar projects: Handles cable routes exposed to splashing, condensation, persistent humidity and seasonal water-level changes.
- Coastal photovoltaic systems: Supports solar installations affected by humid air and salt-rich environments when the complete cable system is designed for the site.
- High-humidity industrial sites: Provides a durable DC connection for solar arrays near water-processing, agricultural and industrial facilities.
- Conventional rooftop and ground-mounted arrays: Offers a robust cable option for projects requiring high water resistance, UV durability and a broad temperature range.
- Repowering and maintenance: Replaces aged or unsuitable DC cable in wet-environment photovoltaic plants during planned system upgrades.

Frequently Asked Questions
What makes this cable suitable for floating solar systems?
It combines AD8 water performance with a flexible tinned-copper conductor, cross-linked polyolefin insulation and outdoor resistance suited to wet, UV-exposed PV cable routes.
Can the cable remain underwater?
AD8 addresses prolonged water exposure for the cable itself. The permitted depth, duration and installation method depend on the final product specification, while connectors and terminations must carry their own suitable water ratings.
Is it suitable for 1,500 V DC arrays?
Yes. The cable is available for 1,500 V DC photovoltaic circuits when the complete system, including connectors and terminations, is rated for the calculated maximum voltage.
Why is tinned copper used?
Tin coating improves the conductor's resistance to oxidation and supports reliable crimping and long-term performance in humid environments.
How should cable size be selected?
Use the design current, route length, allowable voltage drop, ambient temperature, cable grouping and installation method. The highest reference ampacity in a table is not automatically the allowable project current.
Does AD8 eliminate the need for waterproof connectors?
No. Cable, connectors, glands and junction boxes are separate parts of the environmental protection system. Every component must be selected for the actual exposure condition.
