Electrical and Power

Although you may not give too much consideration to your office’s electrical and power cabling, it is probably the most important part of your working environment. Having adequate sockets and power supply for your work-space is critical to supporting your employees and the work that they’re carrying out. We rely on having a consistent electrical connection throughout the day, whether that’s for checking emails or just making a cup of tea, so issues with this provision can cause significant slowdown for your business.

Ignoring the design of your electrical and power cabling, precise load calculations and user requirements could potentially create more work down the line, and compromise the safety of staff members and equipment. It’s imperative that you can provide your staff with the peace of mind that they’re working within a safe environment with connections they can rely on.

If you’d like our team of experts to inspect your current layout, or want advice for refurbishment or upcoming office move, don’t hesitate to get in touch with DIS today.

Choosing the right wire

There are many different types of electrical or power cable available, meaning that our skilled engineers will be able to select the perfect one for your project. Whether you require durable, tough cabling for an environment like a building site, or highly flexible cable that needs to navigate a winding maze to reach its destination, we’ll be able to recommend and supply the correct product for your needs. The following cables are just a tiny selection of the types that can be used within your project for optimal results.

Armoured Cables

These hard-wearing, tough cables feature layers of protection, including galvanised steel and thick PVC, to ensure it can survive even the harshest environment. If your project is located somewhere with rough surfaces that can easily wear down a regular wire, or somewhere with heavy traffic, then an armoured cable will offer you a hard-wearing alternative to standard wiring.

Coiled Cables

Perfect for situations when mobility is required, coiled cables can save space and minimise risk due to their condensed design when relaxed. However, they can easily be extended when a user needs to move with the powered device in question. The most common use for this kind of cable was in old, wired telephones, but there are many applications where coiled cables can be effective.

Solar Cables

Specially designed for use within photovoltaic power systems, this cabling is highly resistant to UV radiation and can operate in an enormous ambient temperature range. Generally used for connecting solar panels and inverters, these cables are designed to withstand not only a range of temperatures, but varying PH levels in salt water environments.

What is an electrical cable?

Although we’ve talked about the different varieties of cable that we might use to power your premises, it’s important to understand the different components within the cable and how they all work together to transmit electricity from your generator or mains connection all the way to your device.

An electrical cable consists of four major parts:

  • Electric conductor
  • Insulation
  • Auxiliary elements
  • Outer sheath

The conductor is the key ingredient of a cable as it channels the flow of electricity from its source to its destination. There are many different types of conductor that can be used, including bare wire, copper or aluminium. Cables can also be single- or multi-core depending on how many conductors they feature.

Conductor insulation helps to prevent current leakage, preserve material integrity and stop conductors coming into contact with one another. Auxiliary elements further protect the cable and ensure that it is long-lasting.

The outer sheath holds all of these interior components together and protects them from external threats such as jagged surfaces, animals, trampling and more. This sheath can be made up of a variety of materials to ensure that it suits the purpose and environment that the cable will be used in.
