Insulating solutions in photovoltaic facilities
The International Standard IEC 60364-7-712 describes the recommended requirements for photovoltaic installations, which usually have specific constraints: Operatign power which can be up to 1500V DC; no RCD´s providing electrical protection between PV panels and inverters; maintenance without switching off the power; climatology (rain and humidity, corrosion, UVs, wind, extreme temperatures, etc).
Our solutions have more than 45 years of experience
in outdoor installations under the influence of UV rays.
Earthing not required.
Maintenance-free.
• Cost saving in maintenance.
Material resistant to corrosion.
• Increased durability of the installation.
Insulating material
Prevents curent leakage towards the conducting element:
Risk of indirect contacts is reduced.
• Higher electrical safety.
• Reduced risk of electrical accidents.
Cutting the cable tray does not produce sharp edges or burrs that could damage the conductor's insulation.
• Reducing the risk of electrical insulating failure.
