Cabling company Nexans has launched a new range of cables, solutions and services specially for photovoltaic (PV) installations. The KEYLIOS products are designed to offer a total connection approach for PV projects, with every high-quality element fully compatible and interoperable to ensure maximum performance, availability, safety and long service life.
This new KEYLIOS range covers every type of cable needed for a residential, commercial or solar farm PV installation. However, Nexans says that its KEYLIOS approach also adds a number of essential services for developers and operators of PV projects — from monitoring and control services through Intelligent Internet Gateways to Life Cycle Assessment (LCA) and simulation.
A key element in the KEYLIOS range is the 0.6 to1kV ENERGYFLEX cables, with cross-linked polyolefin insulation, designed to link PV panels on rooftop or in solar fields and also connect them to the array box or inverter. Resistant to extreme temperatures (-40 to +120°C), ozone and UV, these zero-halogen cables are low-smoke and flame-retardant for enhanced fire security. Both UL and TÜV-certified, they fit main connectors, are color-striped for easy installation and phase identification, meet RoHS directives, and are fully recyclable. They are also available with E-beam cross liked technology with TÜV approval.
Other KEYLIOS cables include low voltage copper or aluminum types that provide reliable, durable links between array boxes and inverters as well as flexible silicone cables that can carry up to 15kV in the challenging conditions found in desert or cold environments, and earth/ground cables for protection against short circuits and fires.
Also in the KEYLIOS range are active switch systems for communications and monitoring. The small, rugged iSwitch systems combine fibre-optic and copper ports to exchange data with and provide Power over Ethernet (POE) to distributed IP surveillance cameras, WLAN access points, VoIP phones or multifunctional terminals. These switches can also be used for control and monitoring applications, and have inbuilt fibre-optic/copper cable diagnostic functionalities.
