An Insight into 3 Core 25mm Armoured Cable

When it comes to electrical wiring, armoured cable is an important product. It is strong and tough and is often used in heavy duty applications where there may be risk of physical damage to cables. The 3 core 25mm armoured cable, in particular, is quite popular as it provides superior protection and flexibility when compared to other armoured cables.

Mostly used in industrial and commercial installations, 3 core 25mm armoured cable is also a preferred choice for domestic wiring. While they are slightly more expensive than ordinary cables, the expense can be justified by the extra protection these armoured cables offer.

Types of 3 Core 25mm Armoured Cable

There are several types of 3 core 25 mm armoured cable available on the market. The two main types are the steel wire armoured (SWA) and aluminium wire armoured (AWA) cables. SWA cables are more expensive than AWA cables but they provide greater protection against physical damage. Both types of cables are typically available in red, yellow and blue colours.

The cable's conductor may also differ depending on the type of application. For instance, the conductor of a domestic 3 core 25mm armoured cable is usually made from copper whereas an industrial cable may have a conductor made out of aluminium. Copper conductors can typically handle higher current levels and so are more suitable for heavier loads.

Safety and Installation Considerations

Installing 3 core 25mm armoured cable requires expertise and skill. It is strongly recommended that qualified professionals install this type of cable. The cable should also be inspected before installation to ensure that all components are of the correct size and that there are no signs of damage. Furthermore, the cable should be properly identified before installation.

When installing armoured cables, it is important to ensure that the right type of conduit is used. For external applications, the conduit must be adequately protected from weather conditions. Care must also be taken to make sure that the termination boxes used are of good quality and are designed to resist corrosion.

Finance and Cost Considerations

When considering cost, it is important to factor in the cost of labour and installation materials as well. As mentioned previously, 3 core 25mm armoured cable is slightly more expensive than ordinary electrical cable. However, its superior protection more than justifies the additional cost. When purchasing armoured cable, it is important to purchase from reputable suppliers to ensure that you are getting quality products.

It is also possible to save money by buying in bulk. Purchasing larger quantities can reduce the price per metre and can result in significant cost savings. However, make sure to buy the correct number of metres that are required for the job. Too much or too little will increase the overall cost.
