Cables for photovoltaic systems
18 August 2010
Interconnection
Lapp Kabel recently launched its product range for photovoltaic cabling under the name Ölflex Solar. All cables are UV-resistant and are characterised by a high level of resistance to weather and temperature.
The latest addition to the product range is the electron beam cross-linked Ölflex Solar XLR. Electron beam cross-linking, a technology used in the aerospace industry, involves cross-linking copolymer molecules to give the material particularly high thermal and mechanical properties. The TÜV-approved cables offer thermal resistance from -40°C to +120°C, thereby guaranteeing long-lasting functionality under any weather conditions.
The standard cross-linked Ölflex Solar XLS solar cables are increasingly being used in temperature ranges from -40°C to +100°C. Both types of cable are normally mounted on flat and pitched roofs and field systems for wiring solar modules together and connecting the individual rows of modules and the power inverter. Due to its large conductor cross-section, the hard-wearing XLS is used in large PV systems as a collective line to carry high electric loads between the individual rows of modules and as a connector to the power inverter. It is also suitable for underground installation.
In contrast, Ölflex Solar V4A is recommended for use on stables, barn roofs and other agricultural buildings. It features a sheath made from rust-free stainless steel and thus offers effective protection against rodents and termites.
To supplement the cables, Lapp Kabel also offers extruded, preassembled or freely configurable Epic Solar connectors and built-in connectors to connect the solar modules. Robust and weather-resistant connector boxes also form part of the company’s solar range. The so-called Epic Solar module box (supplied with or without cable) is attached to the rear side of the solar module. Solar modules can be connected in parallel using Y-splitters. The portfolio is supplemented by corresponding Skintop screwed cable glands and UV-resistant polyamide protective tubes from the Silvyn range.
