GRP Pillars with integral SSE Specification

For permanent installations we make a standard range of CT chambers rated from 800A to 2000A to SSE requirements and for temporary builders supplies (construction sites) we make a standard range of SSE CT chambers close coupled to RCDs, which can be housed in ISIA series GRP pillars.

SP59 - Equipped Stainless Steel Pillar

The Blakley Team has recently been involved with a major project to supply over 40 no. stainless steel pillars to a major industrial complex in the UK. The pillars incorporate a Blakley fuse board fitted with Red Spot fuse banks, which supply critical equipment around the installation. Fuse protection is already widely deployed on the project as it has been found to provide the required level of protection over the long term, even in the adverse operating conditions found on this particular site.

Form 4 MDA

Mains Distribution Assembly with Fuse Combination Switches, 400A, Form 4

The Blakley team have recently been involved in a demanding contract for Mains Distribution Assemblies (MDA), which are to be installed on a major civil engineering project. Although site equipment is usually considered to be temporary, the project is expected to last for more than 20 years and the MDAs have a design life of 25 years.

Outdoor Assemblies Mounted within Crash Frames

Crash Frames were developed for the Generator Hire / Event sector in order to provide a safe means of handling large, high current, high value distribution assemblies. Crash frames incorporate overhead lifting points and fork lift pockets, enabling these top heavy assemblies to be moved safely within depots and on site.

Site Power Clusters, Providing Plug-in 400V and 110V Supplies

Although 110V Reduced Low Voltage remains the predominant on-site voltage to supply temporary lighting and portable power tools on UK construction sites, plug-in 400V power is also widely used across many sites to supply items of mobile plant such as welding sets, mortar silos, dewatering pumps and other items of heavy plant.

Customised MCB & MCCB Boards

In addition to our extensive standard ranges of IP55 and IP66 MCB distribution boards and TDC series of Transformer Distribution Cubicles (which combine RLV transformers with double-pole MCB distribution arrangements), we also manufacture a wide range of non-standard versions.

Improvements to SSE CT Chambers

The Blakley Engineering and Project Teams thrive on the challenge of a major project but they also understand the importance of improving standard products, to make them easier to build or install. A recent example of this has been to introduce a series of improvements to the 2000A CT Chambers that we produce to Scottish & Southern Specification (SSE).

GRP Equipped Pillar for a Trackside Location with Isolation Transformer

We have recently been involved in a rail project where an outdoor cubicle was required to house (i) a 100A rated DNO service head, (ii) a 1:1 ratio, 20kVA isolation transformer to provide separation between the DNO and traction supplies and (iii) switchgear, including a Network Rail approved DC Immune RCD, to supply various loads including a TP Hut and Level Crossing Lights. There was also the requirement for the outer enclosure to be made from GRP.

1000V Plug-in Distribution Assemblies

Although most of the assemblies that we manufacture operate at a voltage of 400V or less, the scope of our ISO 9001 approval recognises that we also design and manufacture distribution assemblies rated up to 1000V and transformers up to 3300V.

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.
