Industrial / Commercial Installations
ESPM are experienced in many electrical installation environments. The type of work carried out in the building will dictate the method of installation.
Office environments will generally have the wiring concealed behind suspended ceilings, plastered walls and raised floors. This method of installation will have adaptability in mind when being constructed. To allow office restructuring and movement of desk pods the electrical infrastrucure will need adaptability built in. Use of plug in lighting modules within ceiling grids and underfloor tapoff connections for desk sockets are common.

Typical office installation with power poles housing power & data and energy efficient direct/indirect lighting in a suspended ceiling grid. Power and data cables installed on separate trays above ceiling grid and run down separate compartments within the power pole. Desks can be positioned so that these power poles can neatly supply the desk management system. |

Typical office installation with dado trunking housing power & data and energy efficient direct/indirect lighting in a suspended ceiling grid. Use of dado trunking is a common method of distributing power, data and voice cabling for office work stations. The design brief was to install sufficient lighting to supply an average of 450 lux on the working plane.
|
Industrial environments where functionality and resilience is necessary, will dictate the use of a more robust installation. Use of steel galvanised containment and heavy duty switches/isolators are commonplace.
|
Typical industrial installation using HRC distribution boards and galvanised containment. This type of installation is the most robust and durable. Single insulated cables are protected by steel galvanised trunking and conduits.

External weatherproof feeder pillar housing MCCB distribution board supplying various outbuildings throughout an industrial site. Liasing with the building contractor ensured the concrete base was constructed to the correct specification and the ducting was laid in the correct positions. Cables were pulled through ducts with the assistance of winching machines operated by trained engineers. |

Hi bay industrial lighting within large shed. The design brief was to install sufficient lighting to supply an average of 300lux throughout the shed. Using lighting design software, the wattage and positions of luminaires was determined.

Self contained mini sub station installed as a replacement power supply to an existing industrial estate. This sub station was fed via a new pole top transformer situated behind. Cables were buried in a trench excavated from this sub station to the existing mains intake room within the building. Full project management of these works were undertaken to liase with the local DNO from enquiry stage involving planning permissions to delivery of new substation. |
|
When larger cables are installed within the ground, it is common to bury direct rather than pulled through cable ducts. These cables laid in on a bed of sand in an open trench 750mm deep. The cables were then covered by a layer of sand before having a protective heavy duty cable protector/warning tape laid on top. The remainder was filled with the excavated material and a top layer of topsoil.
Cable Avoidance Tool was used before excavations were carried out to detect any existing buried live cables. Experienced CAT scanning operators can also detect other buried services if buried services drawings are not available.
