Cable Clamp Material

High quality materials are used to manufacture Cable Clamp, with excellent flame retardant properties, including products that have been approved to London Underground Limited (LUL) Standard 1-085.

All polymer cable clamps are tested to different standards, mainly on fire spread, vertical burning, flammability (oxygen index), halogen gases, toxic smoke and smoke exhaust.

Polymers

Nylon
Standard nylon is relatively hard, dense and abrasion-resistant. This material is usually used in less harsh industrial applications.

Low Smoke (LSF), Halogen Free (LS0H) and Phosphorus Free, V0 Nylon
Nylon polymer, halogen and phosphorus free, provides a low smoke (LSF) solution. UL94 V-0 rating, with good flame retardant properties.

LUL
Flame retardant polymer, halogen and phosphorus free. It has excellent flame retardant properties and has passed the most stringent smoke and toxic fume emission tests, enabling it to meet London Underground Standard 1-085

METALLIC:

Aluminium
Aluminium has low density and corrosion resistance due to the passivation phenomenon. The excellent corrosion resistance of aluminium is mainly due to the formation of a thin oxide film on its exposed surface, which effectively prevents further oxidation.

The yield strength of pure aluminium is 7-11MPa, while the yield strength of aluminium alloys can range from 200MPa to 600MPa.

Aluminium is non-magnetic, very suitable for single-core cables, and is non-flammable, ensuring that the combustion process will not be accelerated in the event of a fire.

5000 series copper-free aluminium is used because of its comprehensive performance characteristics: mechanical strength, durability, corrosion resistance and flame retardancy.

Stainless steel
The stainless steel cable clamp is made of 316L stainless steel. Compared with traditional stainless steel, 316L stainless steel is more resistant to rust and pitting corrosion, and also has higher creep strength, excellent tensile strength and crack resistance at high temperatures.
