PV power cable
2 February 2011
Interconnection
Lapp Group has launched a new type of photovoltaic (PV) power cable for the voltage range up to 1,8/3 kV. The new product will be sold under the ÖLFLEX TRAFO brand name, and was developed in partnership with SMA Solar Technology, a manufacturer of solar inverters. It is specifically designed for connecting inverters to medium-voltage transformers, so that energy generated from the sun can be relayed directly to the high-voltage network.
Suitable for use around the world, even in extreme temperatures, the cable’s key design requirements were flexibility and durability. In addition to having the required current-carrying capacity, it had to be suitable for laying underground with no additional protection, and to this end it was given a reinforced outer sheath. This is made from an electron beam cross-linked material that is highly resistant to UV, ozone and environmental stresses.
The new medium-voltage cable is also suitable for use across a wide temperature range (from -40°C to +100°C), making it suitable for PV systems in areas with extreme climatic conditions.
