Thorne & Derrick with Lucy Zodion supply both standard and bespoke feeder pillars in a selection of materials, paint finishes and dimensions to meet all indoor and exterior power distribution, control and lighting requirements up to 1,000 volts with IP65 door seal – this includes LV substation and network pillars with DNO supply cut-outs for utility applications.
Specialist EV Charging Pillars can be produced to customer specification for electrical vehicle charging points and applications.
The wide range of Lucy Zodion pillars from the Fortress range include mini, slimline, single-door and double-door types available in galvanised mild and stainless steel with cast iron option for heritage applications.
➡ Contact us to discuss how T&D and Lucy Zodion can provide innovative custom design solutions and ex stock delivery of standard feeder pillars to your project.
The series of feeder pillar images below shows a behind the scenes look into the manufacturing of bespoke pre-wired pillars.
Design Process
Lucy Zodion CAD driven design procedure guarantees a well engineered product from enquiry to delivery. The dedicated design team will work with a client not only from the start, but through all the processes to the finished product. Lucy Zodion have designed and produced some very exciting innovative products over the last few years, and T&D offer customers the latest cutting edge technology with highly skilled engineers and designers.
110V, 230V and 400V a.c. variant feeder pillars are available in both above ground and in-ground locations equipped with earth leakage and overload protection devices to ensure high operator safety levels. Compact retractable power pillars with telescopic design to mount flush to the floor surface provide discreet electrical power for typical applications including markets, shopping centres and airports.

Pictures 1 and 2 show the intricate engineering detail that goes into the design of a bespoke pre-wired feeder pillar. Although you can tell that the feeder pillar is only partially complete you can see the attention to detail and pride that Lucy Zodion input into all of their feeder pillars.
After manufacture the feeder pillars are thoroughly tested within the purpose built LV test area at Lucy Zodion to ensure they meet BS7671 and meet the requirements of BSEN 60439. The test procedures and quality assurance inspections driven by the ISO 9001 accreditation ensure all products including pillars perform correctly and safely.

Pictures 7 to 11 show that careful consideration is taken when designing the feeder pillar to ensure that the installer, end user and maintenance team are satisfied with the completed installation. In this case an external override switch which is provided to avoid opening the feeder pillar unnecessarily. Please note the space below the isolator on the right for the Distribution Network Operator (DNO).

Picture 12 shows how feeder pillars can be sympathetically painted to suit their surroundings. Lucy Zodion can paint feeder pillars to any RAL or BS. This specific pillar has been modified to provide temporary supplies for regular events that take place in recreational areas including parks, open spaces, playgrounds, nature reserves, wildlife sites and sports pitches.

Sonel MPU-1
uploaded by Chris Dodds - Thorne & Derrick Sales & Marketing Manager
Sonel MPU-1 leakage current alarm signaller is designed to be installed to measure AC leakage current in low LV and medium voltage MV power networks.
Repairs, renovation, reconstruction, and modernisation of medium voltage overhead live lines always involves the potential risk and danger of breakdown, accident, arc flash or electric shock to employees who are doing the work.
These risks can be minimised through the use of appropriate personal protective equipment such as insulating mats, electrical insulating gloves, dielectric boots and non-flammable clothing.However all these safety measures will not detect increasing current flowing through the pole grounding, that if too high of a level can be the first warning of danger
Sonel MPU-1
The Sonel MPU-1 is designed to make measurements which can define the medium voltage power network’s safety condition for leakage current.
The device enables a limit to be set for a maximum safe value of flowing leakage current and for values above this limit visual and sound alarm is activated. The preset minimum current level where the loud audible alarm with a warning light signaling is switched is 1 A, in accordance with the PTPiREE guidelines.
♦ PTPiREE Polish Power Transmission and Distribution Association was established on 29 August 1990. PTPiREE is an association of the Distribution Network Operators (Enea Operator, Energa – Operator, PGE Dystrybucja, Tauron Dystrybucja, innogy Stoen Operator and PKP Energetyka) and the Transmission Network Operator (PSE). It works for the transformation of the Polish power industry, aiming to improve the operational efficiency of the LV MV HV power network, as well as the quality of services and customer service. Its operation includes consulting, training and publishing.

Using the leakage current alarm signaller it is also possible to manually set a different minimum alarm in the range from 0.5 to 9.9A (with the possibility of an increased alarm range at the time of manufacture for individual needs).
MPU-1 is dust and water proof to IP-67 in accordance with EN 60529 and can operate in temperatures from -10° to +50° C. The device is supplied in a hard carrying case for easy transport also with additional accessories to the workplace and protects against dirt or accidental damage.
