Low Smoke Halogen Free (LSHF or LSZH)

LSHF (a.k.a LSZH) is ideal for installations in public buildings or near sensitive equipment such as computer rooms or datacentres. Not to be confused with LSF cables, LSHF are those which emit minimal fumes in the event of fire.

Low Smoke & Fume (LSF)

Commonly referred to as LSF, these cables are made up of modified PVC compounds which can produce less HCl gas and smoke when burnt than a standard PVC cable. However, the PVC is modified to varying degrees and differ from manufacturer to manufacturer. Generally speaking LSF cables still produce fairly high volumes of dense black smoke and HCl gas. With no formal standards in place to guide the user the amount of HCl gas LSF cables produce can vary between 15% to 24%. By way of comparison, standard PVC gives off up to 28% HCl and LSHF cables are those which emit no more than 0.5% HCl when burned. There is a significant difference between the two products and it is vital that specifiers know which they are choosing.

External & Duct Grade Cables

 These cables have the added protection of a heavy, black, UV resistant, waterproof, polyethylene jacket. The standard PVC inner jacket is retained for added protection and makes termination easier and faster.

The PE jacket not only protects the cable from moisture but also adds to the physical strength of the cable.

Ideal for clipping to masts, running up the sides of buildings, across roofs, or for installations in schools, industrial yards and CCTV networks.

Armouring

For the ultimate protection, many cables are offered with an overall armour and PE jacket.

Using the standard cable as a base, these cables feature a tough, PE inner sheath and 0.9mm solid galvanised steel wires cased in a heavy waterproof PE jacket.

The armoured  cables are ideal for installations where physical damage, vandalism or rodent attack could be a problem.

They are also suitable for direct burial in the ground.
