Alsecure® Plus & Alsecure® Premium: Fire resistant cables

Fire resistant cables ensure integrity of function during a fire by enabling the security systems (video surveillance, smoke ventilation, audio alarms...) to continue functioning for a certain time after the fire has started. Nexans ALSECURE cables comply with these requirements..

Alsecure Plus is Nexans’ full range of Fire resistant cable  based on different technologies  (silicone rubber or mica tape)  in accordance with the national standards.

Recently  Nexans broaden its cable range with a new product bringing exceptional mechanical performance, making the installation  easier: the Alsecure Premium range, based on the patented INFIT insulation technology.

It delivers the same fire-performance characteristics as its predecessors; however, it adds new value to your installations by creating important time-saving and thus cost-saving advantages

Benefits of ALSECURE PLUS® cables 

  • Secure critical applications in high-risk environments
  • Meet extreme fire conditions over an extended period
  • A full range to meet and exceed the most stringent national requirements and the different fire security applications

Benefits of ALSECURE®  Premium cables

  • High flexibility: twice as flexible as mica-tape cables, it is easy to bend and to shape, even with bare hands; 15% less bending radius means that you can go around tight corners, and fit it into confined space
  • Easy strippability: twice as fast to strip as mica-tape cables, with no special tools required; in fact, it can be handled just like any conventional low-voltage building cable
  • Exceptional strength: three times harder than silicone-insulated cables, meaning that the insulation will not be damaged during installation; there is less waste, and a reduced likelihood of system failure during commissioning.
  • Fire resistance performance : Secure critical applications in extreme fire conditions over an extended period

Alsecure® Premium

Innovative INFIT™ technology :

INFIT™ is a Nexans state-of-the-art generic technology, which draws on the latest Materials Science to optimize the structure and cohesion of cable insulations during fire. Based on selected types of polymers and patented specific compositions, it combines the rigid and easy-to-handle surface of traditional XLPE/mica cables with the strippability and installation ease of flexible silicone rubber cables. In the event of a fire, INFIT™ transforms the insulation from a flexible, plastic covering to a tough ceramic layer to assure circuit-integrity (i.e. no breaks or short circuits).

Indoor Installation Cables

Flame-retardant, fire-resistant, power cables for both indoor and outdoor use.

A low level of opacity of smoke produced and acidity of the effluent are basic criteria in the selection of materials that, in the event of fire, make it possible to reduce the presence of dangerous gases and to facilitate escape. It is essential that the production of opaque smoke and harmful emissions is as low as possible during a fire.

Nexans’ offer enables to:

Significantly delay the propagation of a fire, thus gaining precious time for evacuation and fire-fighting
Reduce to a minimum opaque smoke and acid gases, the prime cause of fire-related deaths, and damage to equipment and structures
A wide range fitting the different country regulations, building types and electrical applications.
