Ultra High Output LED Floodlights

The installation of highly efficient LED floodlights for local area lighting has been universally accepted on UK construction sites. However, for specialist applications, such as lighting the deep access shafts found in tunnelling projects, ultra high output luminaires with specialist optics are required.

Automatic Transfer Switch Assembly with Single Line Bypass Facility

Automatic Transfer Switch Assemblies (ATSA) are widely used in many sectors, to provide N+1 redundancy for critical electrical supplies. Applications can range from rock concerts (the show must go on) to providing back-up supplies for Life Safety Systems, such as sprinkler systems and fire fighting lifts installed in high rise buildings.

Tunnel Power Cluster, Slim Line

A lot of factors can drive the design of equipment to be installed in tunnels: the available space is often a key consideration, particularly for items to be installed into existing tunnels. On a recent tunnel project, the design brief was for the enclosure to be a maximum of 100mm in depth with an additional 20mm allowed for covers and switch actuators.

Tunnel Transformers, 3300V

Given the crowded nature of the UK’s major cities and the environmental impact of large scale infrastructure projects, very long tunnels under our cities and countryside are becoming more prevalent.

Site Transformers with Floodlights

At Blakley Electrics, site transformers and 110V site lighting are both key parts of our range and occasionally the two combine...  The Blakley Project Team were recently involved with a major project which had large floor areas requiring 110V power and lighting but, during the initial phases, no walls were available on which to mount floodlights.

Transformer Distribution Cubicles

We manufacture a standard range of Transformer Distribution Cubicles (TDC), which combine single-phase double-wound transformers with an integral MCB distribution arrangement. Transformers are rated from 2 to 10kVA and provide a 110 volt Reduced Low Voltage (RLV) output, with a maximum voltage to earth of 55V from either leg of the secondary winding.

Mains Distribution Assemblies, Form 4

On fast track construction projects there is an increasing awareness of (i) the delays and disruption that occurs when Mains Distribution Assemblies (MDAs) have to be isolated to allow routine activities such as connecting or disconnecting cables and (ii) the hazards associated with NOT isolating MDAs, to carry routine activities such as connecting or disconnecting cables.

New Generation of RCD Protected Combination Socket with Switch Fuse, 63A

When the UK’s fleet of Advanced Gas-Cooled (AGR) Nuclear Power Stations was built in the 1970s and 1980s, high specification maintenance sockets were installed around each plant. Due to the need for completely reliable protection, coupled with the high prospective short circuit levels within the installations, the socket assemblies incorporated integral switch fuses rather than MCBs or MCCBs.
