Outdoor Distribution Assemblies Rated up to 6300A

Despite the in-roads that have been made in reducing electricity consumption in recent years, the rating of switchboards seems to know no limits! The Blakley Projects Team has recently been involved with a project requiring two high current, outdoor distribution boards: one rated at 4000A and one rated at 6300A.

Power Cluster Assemblies for 230V / 400V Applications

The original Blakley range of Power Clusters combines 400V, 230V, 110V and 24V socket outlets into one distribution assembly and requires only a single supply connection. Power Clusters eliminate time spent on site fixing and wiring multiple devices such as isolators, MCBs, RCCBs, transformers, sockets, etc. Power Clusters are fully tested Factory Built Assemblies, they are of uniform appearance and construction and are supplied to site fully wired and fitted, resulting in significant on site efficiency gains.

Stainless Steel Dockside Distribution Equipment

When ships, off-shore rigs and other vessels are first constructed or are in dock for refit, there is usually a significant requirement for temporary power. A wide range of activities may need to be carried out in and around the vessel or structure, such as welding, stress relieving, pumping, drying, lighting, painting, grinding, etc., which require 400V, 230V and 110V supplies to be readily available.

Generator Interface Unit

During the initial stages of many construction projects, mains power is not available and generators are needed to supply the site for periods of months and sometimes years. Even at the early stages of a project, peak loads can be high (tower cranes, site offices, welfare facilities), which requires the provision of significant generated power, often in the range from 250kVA to 1000kVA.

GRP Cubicle for a Trackside Location, Double-sided and Equipped

We have recently been involved in a rail project where a single outdoor cubicle was required to house (i) a DNO service head and (ii) switchgear to supply points heating equipment, supplied from the DNO side of the cubicle. Although most cubicles that we manufacture are fabricated from steel or stainless steel, the requirement on this occasion was for the enclosure to be made from GRP, which we are also able to supply.

Assemblies Incorporating 500A and 800A Single Pole Connectors

When a stand-by generator or a piece of heavy plant needs to be connected in a hurry, the use of very large, multicore, flexible cables fitted with multipin connectors is often impractical due to the weight and bending radius of the cable and the size of the connectors.

Containerised Switchboard

The Blakley team has recently been involved in a major project involving the design and manufacture of a series of bespoke high current switchboards each housed in a dedicated 20’ ISO container.

Surge Protection Devices for Overvoltages of Atmospheric Origin

The protection of installations from the effects of overvoltages of atmospheric origin (lightning) is a specialist topic and although we are not experts in the field, we have acquired knowledge on the subject through the incorporation of a range of Surge Protection Devices (SPD) on major projects for the Construction, Outdoor Event, Rail, Military and Nuclear sectors.

Site Mains Distribution Assemblies with form 4 Segregation

The construction of a major Power Station or Tunnel system requires significant amounts of “temporary” power, to supply accommodation villages, offices for hundreds of site based engineers, welfare facilities for site operatives, complex on-site IT and communication systems, as well as concrete batching plants, tower cranes, hoists and heavy duty electrical plant.

All Insulated Power clusters, LV/RLV and PELV

Since 2013 the Blakley Projects Team has been involved in a major new power station project in the north-west of England. The initial involvement resulted in us supplying high current outdoor switchboards rated

Ballylumford Power Station

Ballylumford power station is a natural gas-fired power station in County Antrim, Northern Ireland, owned and operated by AES Ballylumford Limited. With its main plant generating 600 megawatts of electricity, it is Northern Ireland's largest power station and provides half of the country's power. Overall the station produces 1316 megawatts and is located at the tip of the Islandmagee peninsula, which separates Larne Lough from the Irish Sea.

Isolation Transformers for HOT Sites

A HOT site is a high voltage installation (400kV, 132kV, 33kV, etc.) where the Earth Potential Rise (EPR) that can occur during an earth fault can exceed 430V. For installations at these sites, there is a risk that the EPR could be exported onto the HV or LV network and into a consumer’s premises, where it could cause danger to life or damage to property. Please note that all National Grid sites are generally classified as HOT.

Mobile Power Clusters

Large industrial complexes often have a requirement for multiple voltages around a plant, whether for ad hoc maintenance or planned shutdowns. As an alternative to installing fixed Power Clusters at strategic locations around a site, it is sometimes more economic, particularly on established sites, to adopt mobile distribution assemblies, which can plug into existing 400V sockets.

Safer On-Site Testing

In order to enhance on-site safety, Blakley Electrics have produced a series of Mains Distribution Assemblies (MDAs) fitted with test sockets, which enable a range of installation tests to be carried out “live” and with a very high degree of safety. The fitting of test sockets eliminates the need to remove shield plates or terminal covers and allows essential testing of RCDs and the measurement of earth fault loop impedance, etc., to be carried out safely and with minimal disruption to a project.

Special Distribution Assemblies

When it comes to designing and manufacturing special distribution assemblies, Blakley have unrivalled experience in the design and manufacture of transformer, protection and distribution assemblies for permanent and temporary installations.

Rail Maintenance Depot with DC Immune RCD Protection

When a new train line is opened or there is an upgrade to an existing line, new repair and maintenance facilities may also need to be provided or existing facilities updated. The facilities can be comparatively limited, to enable cleaning and rudimentary repairs to be carried out or they can involve a much higher level of investment to enable significant repairs and planned maintenance to be undertaken, to minimise disruption to services.

New Generation of Dockside Service Units

Back in 1992, Blakley Electrics supplied a total of 20 no. 630A Dockside Service Units (DSUs) to one of the UK’s major Naval bases. After nearly 25 years of service in very harsh environments, SOME of the units now need replacing.

The design of the New Generation of DSUs takes into account the experience gained by users and maintainers of the equipment over an extended installation period and it is expected that an even longer service life will be achieved with the new assemblies.

Automatic Changeover Assemblies for Rail Signalling

Standard Blakley AMF and ATS automatic changeover assemblies incorporate pairs of contactors or ACBs controlled by a Deep Sea Electronics controller. The Deep Sea device is very flexible and can be configured on site, which is useful if the exact characteristics of the generator, or any other aspects of the installation, are not completely finalised at the time of supply.

Riyadh Metro Project

The Riyadh Metro Project is the Mass Transit Rail System currently being constructed in Riyadh, the capital of Saudi Arabia. It is a significant, fast track project consisting of 6 rail lines, 176km of track, 85 stations and a budget of around $22.5 billion. 35km of track in central Riyadh runs under ground and a total of 7 tunnel boring machines are carving out the massive 10 metre diameter tunnels deep beneath the city (by comparison, the Crossrail tunnels are “only” 6.2M in diameter). Work started on site in 2014 and the first trains are due to run in 2019.
