Transformers & Rectifiers Ltd is a privately owned, independent company, which specialises in the design, and manufacture of bespoke transformer, and rectifier equipments. Founded in 1951 the company is located in Guildford, Surrey, England. The location provides good transport links with close access to the motorway system, rail transport to London, and close proximity to both of the major London Airports, Heathrow, and Gatwick.
Transformers & Rectifiers Ltd has steadily expanded its’ product range over the years. Mostly this has been achieved by strategic acquisition of key competitors. Indeed, one of the strengths of Transformers & Rectifiers Ltd is that it has such a wide product range, and personnel with a wealth of experience gained with different companies who have served complimentary sections of the market place.
Among the acquisitions are listed the following well known brand names of: - Partridge Transformers Ltd, Southern Transformers Ltd incorporating Gresham Transformers Ltd, Goodyear Transformers Ltd (Power Transformers), and the Industrial Products Division of Allenwest Brentford Ltd (formally Brentford Electric Ltd).
From such a breadth of products Transformers & Rectifiers Ltd has been able to take advantage of the best products available to it.
At present Transformers & Rectifiers Ltd core product range includes:
Transformers
Fluid filled Transformers, mineral oil, or synthetic fluid - Midel 7131.
|
Dry type, non encapsulated Transformers, employing the Du Pont Nomex Aramid
paper system for minimal combustible material. Available in both naturally ventilated,
and sealed for adverse site conditions type. |
 |
| Cast Resin Encapsulated Transformers . |
 |
Voltage Regulating Transformer. Column type, Brentford Voltage Regulator, dry and fluid filled. Stand-alone, up to 680 V, 2.5 MVA, or in combination with fixed ratio transformers up to capacities indicated.
Voltage Stabiliser. Dry and fluid filled. Used in combination with fixed ratio transformers up to a throughput capacity of 10 MVA.
|
Distribution products that include Neutral Earthing Reactors, Static Balancers that
provided a neutral connection from a three wire supply, and Rural Transformers that
are small rating, ground mounted (pad mounted) transformers complete with HV fuses,
and LV fuses or circuit breakers in built. |
 |
Various methods of cooling can be provided for our range of transformers to suit different locations, and design constraints. Cooling methods include air natural, forced air, and water.
Rectifiers
Uncontrolled diode rectifiers where typical applications include traction, crane, and dock yard power supplies.
|
Controlled thyristor rectifiers. Typical applications include electrophoretic painting,
electro-chlorination, copper winning, metal deposition, essential DC supplied (battery
supplies) and plasma arc. |
 |
In addition we supply other types of rectifier that do not fit into the broad product ranges shown above.
Some applications use Voltage Regulating Transformers as the means of variation. The principle advantage of this type of equipment is that it maintains a high power factor across the full range of voltage variation.
Applications such as cathodic protection commonly use a wide range of control systems dependent on particular installation requirements.
Transformers & Rectifiers Ltd is one of the few companies that design, and manufacture both transformers, and rectifier equipments in house. Producing both types of products give us a greater depth of knowledge of the interaction between them, and the overall requirement, than competitors that produce only one of these products.
