Alsecure® range: Low Fire Hazard cables

Un importante anello di congiunzione tra i singoli livelli di tensione sono le sottostazioni o impianti di trasformazione.

Il fabbisogno di elettricità delle città e dei grossi abitati è costantemente aumentato. Gli impianti di erogazione sono diventati sempre più grandi. Spesso l'approvvigionamento elettrico di parti di una città attraverso cavi a media tensione non è più economicamente sostenibile a causa dell'elevato fabbisogno di potenza. Bisogna quindi creare impianti di trasformazione, che collegano il livello ad alta tensione a quello a media tensione.

Nexans e' in grado di servire questo mercato con i suoi prodotti d'alta tecnologia.

Fire Resistant cables enable the security systems (video surveillance, smoke ventilation, audio alarms...) to continue functioning for a certain time after the fire has started.

Alsecure Plus is Nexans’ full range of Fire resistant cable in accordance with the national standards.

Benefits of fire resistant 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

Cables are not dangerous on their own, but they may sometimes cause fires resulting from bad or ageing installations, wrong calculations of sections, and poor-quality cables installed, etc

Due to the use of organic materials for insulation and sheathing and their huge volume in buildings, during fires, cables can also severely contribute to:

• Increased smoke production which limits visibility and inhibits escape
• Increased carbon monoxide production, the most lethal gas in fires
• Release of irritant gases

In order to save people and goods from these risks, Nexans offers halogen-free cables which prevent fire propagation and dramatically reduce the emission of smoke and hazardous, acidic, and irritant gases, thus allowing people time to exit safely.

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.

The progressive electrification of machinery, and the industry for electrical equipment and tools, creates an increasing demand
for mobile cables...

These cables are used in fixed installations or in installations or in environments were a high degree of flexibility is required.

Especially if control panels or other equipment is moved, these cables are most suitable.

The product range comprises cables which are suitable to interconnect most different applications from control and computer panels
down to lifts, material flow and automation equipment.

Control cables are exposed to a variety of mechanical and environmental stresses. Especially such as tension and pressure to cores
and change of length while bending.

These requirements are met by selecting most appropriate construction principles and state of the art conductor, insulation
and sheathing materials.

The degree of flexibility and...
