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

External Power Supply through Industrial Cable to Grow

26 04 2011

Industrial cables are expected to be high in demand as the global market for external ac-dc power supplies is predicted, following a new study, to grow to 14 billion dollars in 2016.

According to the report ‘External AC DC Power Supplies: Worldwide Forecasts’ by Electronics CA Publications, the industry is experiencing conflicting changes that are reshaping this important area of power conversion.

There is a convergence among average wattages and package styles demanded by a typical system in applications such as communications, computer and consumer.  There are also emerging applications that are demanding higher-wattage power supplies.

The communications applications demands are driving both the highest unit sales and the fastest unit growth rates into the two lowest-wattage categories.

Over the next five years the external power supply market is projected to see considerable growth due to new power architectures, smaller form factors, more efficient designs and improved power management technology.

The demand will be led by the communications, computer, consumer, portable medical and building/lighting segment industries.  It is predicted to grow from 9.3 billion dollars in 2011 to 14 billion dollars in 2016.

Industrial Cable

This type of cable is used in industries which require tough and durable cable to supply their applications with a steady and reliable power supply.

The most common types of cable are electrical cables which are used to provide a flow of electricity to certain applications; these can also be outside and exposed to the elements, so are required to be waterproof and able to withstand human tampering.

Challenger Components has 50 years experience in supplying the right type of industrial cable for their clients requirements – whether they need them for small applications such as computers, or larger devices used in factories.

Industrial cable

17 03 2011

Many applications in industry require cables to function, relying on electrical currents and signals to run.  Industrial cable is a term used to describe all types of cable that is used in this sector.

Find out what type of industrial cable you require, how industrial cable works, and where to buy industrial cable in the UK.

A cable is when one or two wires run parallel to each other to form a single assembly, the wires are assembled this way to take up less room, to keep them organised, and to protect them and the device from damage.

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 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.

The Industrial sector may at some point use all of these types of cables, and for each application the requirements for cable may differ.

Electrical Cable

These types of cable used in industry are adapted to ensure the electromagnetic field they would usually radiate is kept to a minimum.

The effects of this electrical radiation is that nearby conductors or cable will pick up this energy, and this in turn could affect the running of other pieces of equipment, and also cause noise pollution.

Due to this, industrial cables have been adapted to minimise this electromagnetic pickup and transmission, with an extra shielded coating applied to the cable.

Electric Cable Types

The most common types of electric cable used in industry are:

Ribbon cable, Coaxial cable, Twinax cable, Flexible cables, Shielded cable, Multicore cable, non-metallic sheathed cable, and metallic sheathed cable.

Antistatic Bags

15 03 2011

Find out what an antistatic bag is, where antistatic bags are used, and why antistatic bags are important, and the best suppliers of antistatic bags in the UK.

Antistatic Bags

These items are used to ship components as they act as a buffer should the device they are carrying become damaged and leak dangerous toxins or fumes such as electrostatic discharge.

They are usually used to ship or carry electronic components which are more prone to damage than other types of equipment.

The bags are made of plastic and are silver in colour if made of metallised film, or pink or black of made from polyethylene.

If you use a polyethylene antistatic bag it may also come with extra padding such as in the form of bubble wrap or foam.

How do Antistatic Bags Work?

The antistatic bags protect mostly against electronic discharge which may be dangerous to the immediate surroundings.

The way antistatic bags work is by their design where they are made up of layers of protection.  They are therefore, sometimes made up of a variety of different materials, such as rigid black polyethylene box line with pink poly foam.

You could also get one that protects a device with a pink polyethylene bubble-wrap bag.

The antistatic bags are slightly conductive; this means they prevent localised charges from affecting the device – so in this sense they protect the device from exterior destruction.

Pink or green bags have only low-charging material.  This means that while the bag will not be able to create harmful charges, it will not protect the electronic device from electronic fields – so the bags should only be opened in a workstation which is static free.

Antistatic Bag Suppliers UK

Challenger Components sells a variety of quality antistatic bags from the well know manufacturer 3M.

Electrical Cable Types Explained

7 12 2010

There are many different types of electrical cable available. Find out more information about specific electrical cable types and their uses below.

Coaxial cable

This type of electrical cable is used usually for connecting radio transmitters and receivers with antennas. Coaxial cable consists of an electrical cable with a core that allows for conduction of electricity, while the outside flexible tube case protects it.

Coaxial cable differs from shielded cables in that they provide a more controlled and constant conduction flow and are therefore used for radios and radio waves, where constant signal is required to keep the transmission clear.

Halogen Free Cable

Halogen free cables ensure emissions are kept to a minimum and pose as little risk as possible if they were to catch on fire and emit dangerous toxic smoke.

This type of cabling is safer to dispose of too as cables emit toxic smoke when burnt so halogen free ones do not require a special burning facility.

Multi Core Cable

Multicore cable can be any type of electrical cable but with ‘multiple cores’.  In electrical cabling, the central conductor, which is typically copper, is referred to as a ‘core’. If, for example then, a cable had four coaxial cables within it, then it would be considered a multi core cable. It also typically has one wire and is protected by a jacketed cable.

Axial Cable

Axial cable is a type of cable similar to coaxial cable but it has two conductors to allow almost perfect signal to pass through it. It is also shielded by an outer jacket.

If you require cabling and are unsure which type fits your specific needs, Challenger Components can help as they supply all halogen free cables on the market.

New Jacketed Cable Launched

23 11 2010

A leading manufacturer of jacketed cable wire has announced that it has launched a new range of thermoplastic heat-resistant cable jacketed wire, which promises to reduce the time and labour costs associated with installation.

Developed by US company Cerro Wire LLC, a manufacturer of copper electrical building wire and cable, SliPWire is a high heat resistant nylon coated (THHN) jacketed cable with a self-lubricating polymer that the company claim provides improved, lower co-efficient friction.

Self-lubricating polymers are ideal for use in high-temperature applications as they can resist extreme heat. Jacketed cable is used when wiring in order to protect or minimise the fire risk. In construction there are typically two ways to minimise this risk when it comes to cabling. The first is to add a jacket that is insulated and fire resistant; the second is to coat the copper conductor within the cable itself with a mineral insulation.

SliPWire is supposed to reduce costly time on site during installation as it avoids the need for time consuming and messy clean-up activities.

Jacketed Cable Manufacturers 

Jacketed cable manufacturers supply a number of products globally, including jacketed flat cable and discrete jacketed flat cable. One of the leading global suppliers of cable is 3M Interconnect. 3M interconnect are also suppliers of halogen free cabling, which is becoming more commonly used thanks to new fire regulations and safety concerns.
