Electrical Cables

Electrical Cables

Electrical Cables: are used all over the World means that there is a huge Market for them. You can produce Electrical Cables and Target Markets outside the Country. The Truth is that there is a large Market for Electrical Cables in Africa and South America.

What is Armoured Power Cable: Armoured Cable is the name given to any Electrical Cable built with an Armour of Aluminium Wire or Steel Wire Armour. The Armour sits under the Cable sheath to protect the Driver and isolate the Layers.
Should Armoured Cable be earthed: Steel Wire Armour Cables: Maintaining earth continuity. Regardless of whether the Armouring of a Steel Wire Armoured Cable (swa) is employed as a protective Conductor or not, it should always be effectively earthed to ensure the requirements of ADS are met.

Why Armoured is used in Cable: Steel Wire Armoured Cable is Designed to have Mechanical Protection, which is why the Cable is often used for External use. The Armour is used to reduce any risk of the Cable getting Pinched or Damaged; the Steel is used to protect the Armoured Cable.
Is Armoured Cable Water Proof: As others have said Armoured Cable, we have lots of it running fom the house down the Garden to get Power to a Shed, Greenhouse, Workshop and Exterior Power Point. It has the Normal Plastic Coating and thus is Water proof.

How deep should Armoured Cable be buried: 450mm is a generally recommended minimum and 600mm if the ground is likely to be disturbed. However if the Cable were to be Laid under a Fixed Surface then it is Protected and so Long as someone can Identify the Warning Tape before the Cable if any work is done then you should be OK.
What is the Advantage of Armoured Cable: Trough Complete and good Handling, it will be a good and Normal Insulation tube to protect 3 core Armoured Cable. With great Performance in insulation, Mechanical, without Rust, Aging and Strong Adaptability, you can use it, Cause it have Great Advantage in using. 1.It has great Anti Corrosion and Long Services Life.

What is 4 core Armoured Cable used for: Made of 4 Copper individual Colour Coordinated Cables hence the name four Core Cable. 5 Core SWA Armoured Cable is most commonly used in Low Voltage Transmissions and uses a three phase Line with one Zero Line for the Power Supply.
What is a 3 core Cable: 3 Core Cables. Domestic light Fittings that are controlled by two Switches (two way lighting) use 3 core and earth for Connections between the two Switches. The Cable is made up of 3 Solid Cores, which are individually Insulated and Wrapped in an outer PVC Sleeving.

What does a GREY Wire mean: White and gray indicate a Neutral Wire. White is the Color most Often used for this Function. Although Neutral, they can still carry Current, Particularly the unbalanced load the Electricity not being used and being returned to the Electrical Service.
What is Electrical Armored Cable: Going under alternative names such as Metallic Sheathed Cable, type AC, MC, Greenfield, or Armored Cable, BX Cable is a collection of Plastic coated insulated Wires (typically 14- or 12-gauge), Bundled together and protected by a Ribbon-like Metal Sheathing. Romex is one Popular brand of NM Electrical Cable.

Can I Wire Armoured Cable to a plug: Armoured Cable can be connected to 3 pin plug of Commando type but not to a 13A plug without some Junction box. Most Caravans will be Supplied from a RCD with a 2.5 or 4 mm sq Flexible Cable Laid across the grass.
Difference between MC and BX Cable: For those who are not Familiar with the difference between the two, BX has a Mechanical ground as part of the Armored Cable Wall or Jacket, where MC has an "extra" green Wire that is used for grounding purposes. Those are the only differences between the two Cables.

Where is Armoured Cable used: Commonly known as SWA Cable, the Steel Wire Armoured Cable is a Power and auxiliary control Cable, Designed for use in mains supply Electricity. Used for Underground Systems, Cable Networks, Power Networks, Outdoor and indoor applications, and Cable Ducting.
Does Armoured Cable Need Conduit: Whilst the weight and rigidity of Armoured Cables can make them hard to handle and time Consuming to Terminate, they are essential in applications where Unarmoured Cables may be Prone to Damage and require Containment Protection, Conduit or Trunking.

What is the advantage of Armoured Cable: Steel Wire Armoured Cable is Designed to have Mechanical Protection, which is why the Cable is often used for external use. The Armour is used to reduce any risk of the Cable getting Pinched or Damaged; the Steel is used to protect the Armoured Cable.
Do I have to use Armoured Cable outside: Armoured for underground, generally. Mains outside would be preferable if in waterproofed Conduit, Protection should be RCD type too. Or you could run it along the back of the wall in Earthed Steel Conduit or heavy gauge pvc Conduit. Butyl Flex is Rated for Outdoor use but has no Mechanical Protection.

How do you Terminate Armoured Cable: The "standard" approach is to work out where you will want the Armour Wires to end, and use a small Hacksaw to Cut a Ring around the Circumference of the Cable, through the outer Insulation, and about Half way through the Armour as you go.
