Prysmian FP Fire Resistant Cables

Prysmian Afumex LSX Low Smoke Zero Halogen Screened Wiring Cables 

Prysmian Afumex LSX and FP Plus have been specified and installed at the new campus for Les Beaucamps High School in Guernsey. Prysmian Afumex LSX will supply general lighting and power in all main classrooms, offices and service corridors. 

Prysmian FP Plus forms part of the fire alarm system with its enhanced performance. Safety for staff and pupils is of paramount importance and with this in mind Lauren Lloyd (Guernsey) Ltd, opted for Prysmian FP cables in their installation at the new facility.

The main contractor at Les Beaucamps site, RG Falla, also based in Guernsey, engaged Lauren Lloyd for the electrical work at the site. Installation began in October 2011, with 35km of Afumex LSX™ 1.5mm² to 4mm², two and three core and also 10km of two core 1.5mm² FP Plus™

Contracts Director Gavin Charles, at Lauren Lloyd explains: ‘Afumex LSX™ was used on this project as an alternative to PVC Twin and Earth as this is a more robust alternative with a better reaction to fi re. This was my fi rst experience of Afumex LSX™ and I am very happy with the results.’

Afumex LSX is a low smoke zero halogen (LSOH) cable with flame retardant properties, a safer alternative to PVC in the event of a fi re. Afumex LSX™ will self extinguish when the fl ame is removed producing low volumes of smoke, free from toxic halogen acid gases present in the PVC alternative.

Prysmian Afumex LSX Cable Features

• Easy to strip, terminate and gland
• Easy to install for surface clipped, tray and basket installations, giving reduced installation costs
• A robust screen that meets the nail penetration test given in BS 8436 70°C operating and 250°C short circuit temperature
• Full size CPC conductor on 2, 3 and 4 core cables
• Provides excellent resistance to ignition and ame spread and produces very low levels of smoke and virtually no acidic gases when burnt, safeguarding human life and protecting equipment
• Dressable - retains shape when installed
• Plain annealed copper solid or stranded (class 1 or 2) conductor complying with BS EN 60228
• Robust thermoplastic LSOH sheath
• AFUMEX LSX screened wiring cables comply with 1.0mm² to 2.5mm²

Les Beaucamps High School currently houses 500 students and additional facilities are being added to cater for an increased intake.

The new facilities are being built adjacent to the current school so that the pupils can carry on with their studies undisturbed. The school is currently in the fi rst phase of the £30 million redevelopment due for completion July 2012, with the second phase, following the demolition of the old school, providing a sports hall, swimming pool and external sports facilities ready for completion in December 2013.
