A brief guide to electrical distribution systems

For over 20 years here at Rubber Box, we’ve been a market leader in supplying electric power distribution boxes and equipment to some of the largest venues and events in the world, including Formula 1. Our market leading expertise means that we can advise you on a range of electrical issues. So, with that in mind, here’s a brief, non-complicated introduction to the different kinds of electrical distribution systems.

What are electrical distribution systems?

Essentially, electrical distribution systems do exactly what they say on the tin – distribute electricity. In really easy terms, ‘distribution system’ refers to the manner in which electrical energy is transmitted from the generators to the many points of use, namely the power lines and circuits that pass through streets and towns to the consumer.

There are only really three different types of electrical distribution system designs: Loop, Radial and Network. More often than not, these three different systems are used in tandem with each other in well-built areas. In more sparsely populated areas though, the Radial distribution system is often preferred because it’s the cheapest to build.

How do electrical distribution systems work?

We’ll spare you the lengthy science lesson and just give you the basics of the process. The electrical distribution process comprises three major components:

  1. Generation – a high voltage transmission grid and distribution system.
  2. Handoff – the ‘handoff’ between electric transmission to electrical distribution usually occurs at the sub-station (sub-stations change voltage from one level to another).
  3. Distribution – sub-stations are usually equipped with monitoring facilities so that switchgear and auxiliary equipment can be activated remotely.

There’s a lot of control, protection, transformation, and regulation that takes place in a power distribution system, so it’s important to ensure that the methods you use to distribute your power are safe and fit for purpose. That’s where we can help.

Power distro boxes

Sometimes referred to as a power distribution unit (‘PDU’) or simply a distro, a power distribution box is used to safely distribute electricity from the power source to other devices in a circuit. It typically has one input and multiple outputs, allowing several devices to be connected to the distro rather than directly to the power source. This makes things safer, more efficient and more convenient; one of its key advantages is that it reduces the chances of blown fuses or even dangerous short-outs.

The shapes, sizes and construction of power distribution boxes can vary widely, and they’re often made bespoke. (In fact, bespoke power distros make up one of our key services here at Rubber Box.) The possible variables include input and output ampage or voltages, and the number of inputs can be increased or decreased to your specifications. They can also be manufactured with extra safety features, such as MCBs and RCBs.

So, that’s a small bit of insight into the kind of work that goes into creating a fully functional power distribution system. Here at Rubber Box, we stock a wide range of power distribution equipment, including both our standard range of products and an array of bespoke equipment.
