PV-Ultra - Double Insulated Multicore DC Cable
PV-Ultra is a durable cable specifically crafted for DC interconnections within solar photovoltaic systems. With outstanding mechanical properties, it can be installed both internally and externally. Constructed from high-quality materials, it boasts an expected lifespan of approximately 25 years. The cables are designed to operate at a maximum conductor temperature of 90°C, with a permissible maximum conductor temperature of 120°C for up to 20,000 hours, under a maximum ambient temperature of 90°C.
Features and Benefits
- Easier to handle and identify
- Saves installation costs and installation time
- Easier to route along/through buildings or walls
- Gives a cleaner, neater installation
- Safer as it removes the need for junction boxes
- Safer as it looks like a power cable to reduces the risk of accidental damage
- Pre-marked ‘LIVE DC’ warning message to improve safety
Current carrying capacities based on ambient temperature of 60°C , for temperatures above 60°C temperature derating factors should be applied as follows 70°C=0.91, 80°C=0.82, 90°C=0.71. Refer to BS7671 for further guidance.
