Insulating solutions in photovoltaic facilities

The International Standard IEC 60364-712 describes the recommended requirements for photovoltaic installations, which usually have specific constraints: Operating power which can be higher than 700V 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).

 

To meet the requirements of cable conduction and protection in the different areas of photovoltaic facilities, Unex offers a wide range of possibilities providing:

• Electrical safety:

• Insulating material. High dielectric strength.

• Earthing not required.

• Avoids leakage currents, hot spots and electrical arcs.

• Mechanical resistance. Sturdy design, high impact resistance even at low temperatures.

• Resistance to corrosion.

• Over 40 years experience in outdoor installations.

• Protection for the cables.

• Quick and easy mounting.

• No maintenance.

Solutions adapted to weathering and extreme climatology

With enhanced technical characteristics and our own naming system.

Cable conducting elements may reach a higher temperature than the surrounding area due to close heat sources and to the effects of the sun and reflection. Unex solutions cover a temperature range from -50ºC to +90ºC (-58ºF to +194ºF) in outdoor applications.
