A-Z of electrical components: H – Halogen-Free Cable

31 10 2011

Low smoke zero halogen (LSZH) is a material classification which is mainly used for cable jacketing in the electronics industry. More specifically, it is used within the wire and cable sector of that industry.

LZSH cable jacketing is typically made up of thermoplastic or thermoset compounds which emit low halogen levels when exposed to extremely high sources of heat.

In the event of a fire, a halogen-containing plastic material can release a poisonous gas that can lead to hydrochloric acid.

In contrast, halogen-free cables will not produce any sort of dangerous gas/acid substances even when exposed to a strong flame.

Halogen-free cable is also lighter in the majority of cases. This means overall cable network system weights can be reduced.

Industrial cables

A vast number of different applications within the electronics industry require industrial cables to function efficiently and precisely. Industrial cables can be used to describe various types of cable that is used in this particular sector.

A cable can be most accurately described as when one or two wires run parallel to each other to form a single assembly. The wires are assembled in this way to take up less room and to make sure they remain organised.

Industrial cable can be used in mechanical terms to lift heavy applications through tension – these are often called wire ropes.

In terms of electrical engineering, cables are used to carry electric currents and there are two specific types of electric cable.

-One is used for installation in industrial sites and other buildings, and the other for power transmission at distances greater than a few kilometres, usually referred to as power cables.

-Another type of cable is optical cable which uses optical fibres which are protected by a protective jacket
