Our Part in Defence & Military services

Originally posted on rbaker.co.uk

R Baker (Electrical) Ltd is a long-standing supplier to the defence sector carrying out ongoing day-to-day projects for some of the biggest names in the industry, including the Ministry of Defence, BAE Systems and Babcock Marine.

Our multi-disciplinary teams offer in-depth experience and understanding of NATO stock number equipment which includes the manufacture and repair of a wide range of equipment. Our understanding and experience of military standards allows us to modify designs to meet any new or changing requirements which may emerge. Our team also have the ability to develop military prototypes and issue in-process CAD drawings to assist with the design process.

We are proud to have worked on some of the most prestigious projects the Ministry of Defence have been involved in. This includes being the manufacturer of the lighting transformers for the new Queen Elizabeth Class Aircraft Carriers.

R Baker (Electrical) Ltd also has an enabling agreement with the UK Ministry of Defence under the Framework for Technical Support initiative. Using this method of contracting R Baker (Electrical) Ltd is easily contracted by the MoD for any task — from the simple to the most complex through a simple procedure with the minimum of delay.

Our quality standards and procedures are monitored independently to BS EN ISO 9001:2000 and are subject to regular external and internal audits; including being accredited by Achilles UVBD, CHAS and Ministry of Defence AQAP-1.. We also work with all the leading testing and quality authorities such as BSI, DNV, Lloyds, NSN, Nemko and VDE to give you total peace of mind.

Defence transformers

All of the military transformers (NSN / NATO) that we manufacture and repair for defence applications, fully comply with the shock and vibration requirements of NES 501 and DEF STAN 02–535. Our type tests also include self-induced vibration and EMC requirements for military vessels, and selected products have been shock tested by an MOD approved agency (QinetiQ).

Transformers are normally manufactured to be hard mounted to bulkheads and decks, and do not require shock mounts. All equipment is manufactured to a minimum of IP23 of BS60529 and to Cat.2 Shock Grade C. Units are normally naturally air-cooled and mounted in IP rated enclosures.

Defence electronic services

R Baker (Electrical) Ltd repairs and reconditions electronic equipment across a range of industries, working with leading clients in the marine and military sectors from our repair facility based in Liverpool. We offer a full industrial electronic repair and calibration service including NSN products.

Our PCB testing and inspection capability supports our electronics manufacturing processes to help ensure that customers receive working products on time, every time. Each electronic refurbishment comes complete with an electronic project folder which is created to ensure that all relative documents and certifications are traceable.

Our electronic inspection and testing service includes a visual inspection of all electronic components, carried out by our highly skilled team.

Reverse engineering

Most of our work in the defence sector involves reverse engineering obsolete military items and providing a certificate of testing where required. Here at R Baker (Electrical) Ltd, with over a quarter of a century’s expertise in military servicing, we have the knowledge necessary to deliver the electrical projects which others turn away.

All of our products pass through our quality control system, and are tested to the highest standards using state-of-the-art equipment. Our investment in new methods and technologies allows us to offer expert reliability when repairing or manufacturing any new products.

Case studies

Isolation transformer

Over the last 20 years we have worked in partnership with major manufacturers of naval weapons sensor platforms and defence systems. Our highly skilled team have developed toroidal, single phase and three phase transformers from 20VA up to 3.2KVA, all within very precise tolerances (within 0.2%). Developing the manufacturing process and necessary testing procedure has required close collaboration with our customer, something we encourage wherever necessary.

45kVA isolation transformer

We enjoy a strong relationship with the MoD and manufacture a wide range of transformers for use within a military application, including isolation transformers. These transformers range from 1kVA up to 150kVA and are used frequently at the Ministry of Defence.

Emergency lighting transformers

We have long lasting relationships with BAE Systems that sees us regularly undertake large-scale project work for their operations. In 2009 R Baker (Electrical) Ltd manufactured key electrical transformers for The Queen Elizabeth class super carriers, which are expected to enter service in 2016 and 2018. We also manufactured fuse panels for HMS Ocean and the Khareef class Corvette project. By working in close partnership we offer BAE Systems a high level of service, from design to development and manufacture.
