More information about Site Transformers

Site Transformers

In the tough world of construction, reliable power is a must-have, and that's where our range of Site Transformers comes into play. Built to power up your tools and lights, these transformers are the workhorses of any building site. They range from 1.5kVA to 10kVA, ensuring you have the right juice for any job. Whether drilling, sawing, or lighting up the work area, these transformers are up to the task.

Stepping down the standard 230v mains power to a safer 110v is the norm for site tools and lighting. This means you can run your power tools intermittently and keep your lights on continuously. With a range of power options available, you can choose the perfect transformer to match the demands of your site, whether it's a small job or a bigger project.

Each transformer in our collection is built to be tough and are all Trade Rated. Designed to handle the rigours of construction sites, ensuring your power supply remains steady and reliable.

How are Site Transformers used on a Construction Site?

Voltage Conversion

The main function of site transformers is to convert the standard UK mains voltage of 230 volts to a safer, lower voltage of 110 volts. This is crucial because most power tools used on construction sites in the UK operate at 110 volts for safety reasons.

Powering Tools

Transformers are used to connect and operate a variety of power tools. Whether for drilling, cutting, or any other power-intensive task, the transformer ensures the tools get the right voltage.

Continuous Lighting

Besides tools, these transformers are also used to provide a continuous power supply for lighting on construction sites. This is particularly important for work during early morning, late evening, or in areas without natural light.

Things to consider:

When purchasing site transformers for construction work, it's important to consider several key factors to ensure you get the right equipment for your needs:

  • Power Capacity: Choose a transformer with the appropriate kVA rating for your needs. The transformer must be capable of handling the total power demand of all the tools and lighting you plan to connect. Common sizes range from 1.5kVA to 10kVA.
  • Voltage Requirement: Ensure the transformer steps down to the correct voltage for your tools. In the UK, this is typically from 230v to 110v, the standard for construction site equipment for safety reasons.
  • Number and Type of Outlets: Consider the number of tools or lights you need to connect simultaneously. Make sure the transformer has enough outlets, and check if they are the right type (e.g., 16-amp or 32-amp sockets).
  • Portability and Size: If you need to move the transformer around the site, look for a model that is portable and not too bulky. Some transformers come with handles or wheels for easier transportation.

Frequently Asked Questions

What is a Site Transformer?

A site transformer is a vital piece of equipment, designed to enhance electrical safety and compatibility with tools. It primarily functions by converting the standard UK mains voltage of 230 volts down to a safer 110 volts, which is the norm for construction tools in the UK.

This step-down in voltage significantly reduces the risk of serious electric shock, especially in an environment where dampness and metallic surfaces are common. Site transformers are used to power a variety of tools and provide continuous lighting, and they come equipped with multiple outlets to facilitate simultaneous connections. Built to be robust and portable, they are well-suited to withstand the harsh conditions of construction sites, making them an indispensable component for safe and efficient operations.

How do I choose the correct site transformer?

When selecting a site transformer, the first and most crucial step is to accurately assess your power requirements. This means calculating the total power demand of all the tools and equipment you intend to use at the same time.

Check the wattage or amperage of each tool and add them up to determine the overall load. This total will guide you in choosing a transformer with the right kVA (kilovolt-ampere) rating.

For instance, light-duty tools might only require a 1.5kVA transformer, while more power-intensive tasks or multiple tool operations might necessitate a transformer with a capacity of 10kVA or more. It's essential to get this right, as an underpowered transformer can lead to tool performance issues or safety hazards, while an overly powerful one may be unnecessarily expensive and bulky.
