Cables for use in photovoltaic solar installations

The national energy deficit, the real estate crisis, the Kyoto protocol, el legislative support and a growing social awareness with respect to renewable energies form a new scenario full of attraction for landowners, investors, promoters and municipal governments, leading to the so-called “Solar Gardens”.

Apart from other photovoltaic installations, normally smaller and more compact, solar gardens are large extensions of photovoltaic modules installed in groups in rural land and next to a substations of the national power network, where they are connected to inject in medium or low tension the transformed solar power. The solar radiation is collected in photovoltaic cells, is transformed into current and transported through a connexion to an inverter, which converts the continuous current into alternate to introduce into the network. The power developed will depend on the number of modules installed, for which the range of cables must cover all possibilities.

The properties to be taken into account for these cables are concentrated in: thermal factors, element factors, electrical security factors and under fire conditions and mechanical resistance factors. Attending to these properties, TopSun PV cables, manufactured by Top Cable for photovoltaic installations, are the complete solution.27
The TopSun PV cable has been specifically designed by Top Cable to withstand the most demanding conditions. Its excellent properties make it the best cable for all Low Tension installation. Given their special properties, TopSun PV cables constitute the ideal solution for connexion between panels and connection boxes of a solar photovoltaic installation, being able to function  at room temperature of up to 90ºC. They have a useful life of 30 years at 90ºC, being able to withstand up to 120°C permanently in the conductor.

Moreover, photovoltaic installations tend to be exposed to all possible atmospheric weather and in all their intensity, especially to ultraviolet radiation, humidity and sudden changes in temperature. For this reason, photovoltaic cables must have a specific weather resistance guarantee that guarantees their operation in time. The materials of the TopSun PV cable have been especially designed to withstand the most demanding weather  conditions without suffering important changes in their mechanical and electrical characteristics.

TopSun PV cables are halogen free cables, do not spread fire and with reduced emission of opaque smoke. Given their fireproofing and the low corrosiveness of the gases emanated cause them, in addition to being very fire resistant, to also preserve persons and the valuable electrical  equipment of the solar installations. To offer an adequate protection against attacks by rodents, and additional to any mechanical aggression, Top Cable manufactures TopSun PV XZ1FA3Z-K range, armados with corrugated aluminium bands. Its main application is the connection in continuous current between the connection boxes and the inverter, as well as between the inverters and the transformer in alternate current.
