Fireproof Rated Cable Cleats &#; Ellis Patents

Cable Cleats

Thorne & Derrick distribute Ellis Patents Fireproof Rated Cable Cleats for low, medium and high voltage electrical systems, typically distributing LV 6.6kV-11kV-33kV power &#; we provide competitive prices for LV-MV-HV cable cleats, clamps and hangers from extensive stocks to UK and international destinations.

Fire resistant cable cleats are installed to clamp, support and fix fire performance cables forming part of the emergency and essential building service systems required to operate in the event of fire &#; FP fire rated cables are primarily used for fire alarm systems, emergency lighting and voice alarm systems.

Cable cleats should demonstrate fire resistance and low smoke which limits the effects of toxic fumes and smoke during a fire thus facilitating effective escape in the event of a fire and reducing collateral damage to expensive and critical equipment.

Fire Rated Cables & BS-1:

Fire rated (FP) cables and their performance in fire situations are covered by British Standard BS-1: &#;Fire Detection & Fire Alarm Systems For Buildings&#; &#; this current standard covers:

•  Wider definition of critical fire cable circuits
•  Two different levels of fire resistance for cables
•  New fire test requirements for cables
•  New recommendations for networked systems
•  New guidance on segregation
•  Restrictions on the use of multicore
•  Stricter requirements for cable fixing, cable cleats and support materials

Currently no standard is published to specifically address the securing and clamping of fire resistant cables using cleats &#; with FP cable typically related for operation in temperatures ranging from 850°C to 950°C then the use of plastic cable cleats or clamps is prohibited.

Similarly, aluminium cable cleats with a typical melting point of 600°C would fail to support FP type fire resistant cables.

Fire Rated Cable Cleats

London Underground Approved

LUL approval for cable cleats requires products to undergo a series of material performance tests relating to toxicity, smoke emissions and the Limiting Oxygen Index. These tests are carried out in accordance to the relevant standards and once LUL compliance is achieved the cable cleat becomes &#;compliant with the requirements of London Underground Standard 1-085&#;.

The cable cleat product range is then allocated with a unique Product Register Number and placed onto the LUL Intranet system used by specifiers and buyers working on LUL projects.

All Ellis Patents cleats have undergone testing at the Building Research Establishment to ensure complete compliance and assurance of performance in fire situations. The BRE compliance is aligned with the London Underground 1-085 specification:

• Smoke Emission
• Limited Oxygen Index
• Fume Toxicity

The appropriate cable cleats manufactured by Ellis Patents are listed in the London Underground Approved Products register with identification numbers 360, 361, 362, 363, 364, 365 and &#; should you require any assistance with the specification or supply of cable cleats to support rail cables in stations, tunnels or sub surface please do not hesitate to contact us.
