Fire Performance Cable
We supply a full range of fire resistant and fire performance cables, often also referred to as fire survival cables, fire-proof cables, or simply fire cables.
This includes our Standard and Enhanced grade cables manufactured in accordance with British Standards BS7629-1, BS5839, BS EN 50200 PH30 / PH60 / PH120, BS7846 and BS6387 CWZ PH120. These include BASEC-approved and LPCB-certified cables. We also have a range of Firetec cables, including the Power and Impact Power cables which form part of the London Underground approved cable portfolio and appearing on the Approved Product Register (LUL APR).
Our fire resistant cable range is designed to ensure that emergency systems in public buildings continue to operate in some of the most extreme fire conditions.
Fire Performance cable products
Our fire performance cables are specifically designed for augmented fire resistance in applications including the delivery of power and auxiliary control in fire alarm systems, voice alarm systems, and emergency lighting systems including those applications designed to meet BS5266. These cables will form part of the requirements of BS8519 for the installation of fire-resistant power and control cable systems for life safety and fire-fighting applications.
These fire resistant single core and multi-core cables are suitable for use within a number of Control Circuit categories. For added protection against the risk of mechanical damage, we supply robust Firetec 'Power' and 'Impact Power' cables, both of which are suitable for indoor and outdoor applications. The 'Impact Power' is designed to withstand direct impact and water jet pressure.
Other fire resistant cables in our fire performance range include Mineral Insulated copper cables (MICC), designed to offer the ultimate fire resistance and good protection against electromagnetic interference. These high temperature cables are manufactured without any plastic insulation and provide circuit integrity up to 950oC. They are also available with LSZH oversheathing in various colour options. These cables are principally used within hazardous and explosive environments or where corrosive chemicals may affect performance. Those without polymer oversheathing have ATEX approval and comply with the EU directives on working within hazardous or explosive environments.
Important fire performance cable definitions
Fire resistant single core and multicore cables - PH30 / PH60 / PH120 cable - fire rated
|Fire proof cable duration||Applications|
|PH30 cables are suitable for emergency applications where the circuit must remain operational for up to 30 minutes|
|PH60 cables are used in emergency applications, in particular emergency lighting to BS5266 where longer circuit operation is required in the event of fire|
|PH120 cables are designed for installations requiring enhanced circuit integrity for up to 120 minutes, This includes complex or high-rise blocks of flats requiring a longer evacuation period.|
Standard fire resistance vs Enhanced fire resistance
|Level||Manufacturing British standard||Applications|
|Standard fire resistance||BS7629-1,
BS EN 50200 PH30, PH60 and PH120
|Fire resistant single core cables and multicore cables for BS5839-1 (most fire detection and fire alarm systems), BS5266 (emergency lighting and standard application circuits), and BS8519 (life safety and fire-fighting) category 1 control circuits. Where used under standard BS5839-1, standard fire-resisting cables should be considered to provide sufficient resistance to the effects of fire, with appropriate methods of support and jointing.|
|Enhanced fire resistance||BS7629-1, BS8434-2,
BS EN 50200 PH30, PH60 and PH120
|Enhanced fire resistant cables are used in most public or complex buildings requiring emergency systems to remain operational for a minimum of two hours (PH120) in compliance with BS8434-2 and BS8519 category 1 & 2 control circuits. They are used for unsprinklered buildings with phased evacuation, unsprinklered buildings in excess of 30 metres in height, and where the designer, specifier or enforcing authority determines it is necessary on the basis of fire risk.|
Fire resistant vs flame retardant cables
An important distinction exists between fire resistant cables and flame retardant cables, even though both of them are subjected to various fire performance tests in order to earn their respective classification. In brief, flame retardant cables are designed to resist the spread of fire into a new area. Fire resistant or fire rated cables are designed to maintain circuit integrity and continue to work for a specified period of time under defined conditions. The distinction between the two is crucial when it comes to maintaining critical circuits required for life safety or for a safe and immediate plant shutdown.
|Fire resistant (fire rated) cables||Continues to operate in the presence of fire, hence their reference as Circuit Integrity cables, This includes PH30, PH60 and PH120 cables.|
|Flame retardant cables||Fire performance limited to not propagating fire|
