Nexans Alsecure NXS Cable

CSE Cables Comment : The Nexans Alsecure NXS is set to become one of the most sold cables in the UK due to the new wiring regulations BS7671, replacing twin and earth and some SWA cable installations. It is suitable for industrial and domestic wiring applications as it can be buried in concrete, attached to brick, stone, metal, wood and behind plaster. If the Alsecure NXS’s aluminium sheathing is penetrated by a sharp object (e.g. nail) it will trip a circuit breaker.

Name : Alsecure NXS to BS6004 and BS8436

Applications : Multipurpose including partitioned walls and voids. For power, lighting and control circuits. Fail safe will operate a 32A Type B MCB circuit breaker when penetrated by a sharp object.

Voltage : Alsecure NXS is 600 - 1000V like a BS5467.

Benefits : Installed benefits compared to traditional fixed wiring installations include large time / cost savings, much lighter and smaller compared to SWA.

Design : 1. Conductor - XLPE insulated stranded copper
2. Uninsulated protective conductor - Uninsulated tinned copper earth conductor
3. Screen - Bonded Aluminium Screen
4. Outer Sheath - Low smoke halogen free UV stable

Marking : Alsecure NXS Pre wired conduit cable

Core Identification : 2 cores and earth : brown - blue
3 cores and earth : brown - black - grey
4 cores and earth : brown - black - grey - blue

Installation : Standard stuffing glands can be used. The wiring regulations BS7671 should be adhered to at all times. NXS can be installed in cable trays and baskets, direct on most surfaces and behind plaster. Indoors and outside.

Bending Radius : 6D

The Alsecure NXS is a general wiring cable not a fire resistant even though it has the same brand name. It is white in colour and like an SWA without the armouring. Traditional contractors will normally use a conduit cable NXS is a pre-wired conduit cable, which inevitably makes it simpler to use, therefore saves time and money.

Information & Uses : It is a power cable, which is used for lighting. It is mechanically protected for example if you were to hit it with a hammer it will operate a circuit breaker. It also has an aluminium screen. NXS has a memory that enables you to bend the cable and it will stay in place, this also makes it simpler to dress.

Example ordering code: 2 x 1.5MXSWHITE100 (change core size & mm size accordingly).
