Our G Corner type high vibration cable terminals are manufactured from high conductivity seamless copper tube, annealed and electro-tin plated to combine maximum electrical conductivity with mechanical strength. An inspection hole is provided to check cable location prior to crimping.
These terminals are manufactured in three bend types and to suit a range of cable sizes – from 10 mm² to 400 mm². The palm of each terminal is stamped with a crimp size code letter to ensure the use of the correct Tranect crimp die. The crimp can then be checked using a Tranect ‘GO’ gauge Type D standard terminals have squared ends to increase surface contact area and to provide additional resistance to rotation.
The type W standard terminals have a wider, thinner palm to increase contact area and enable clamping with shorter larger diameter studs – useful in restricted access areas. The palm also has slightly rounded ends to reduce the risk of flashing in confined spaces.
In 1963 the Associated Electrical Industries Ltd., Traction Division, based at Trafford Park, Manchester, set up a technical committee to investigate all available terminals and to recommend a type for use on all traction contracts. For cable sizes over 0.01 in² (6 mm²) to 0.6 in² (400 mm²) the committee recommended the use of G Corner terminals, which were found to be superior for mechanical strength, electrical performance and to be the most economical. TRANECT Ltd are proud to still manufacture these products with the same qualities of performance and economy as in 1963. Our high vibration terminals are used in cable assemblies and bogie earthing leads on many trains on Britain’s rail network.
In 1985 the British Railways Board adopted G Corner Terminals into Workshop Overhaul Standard Specification 560/4. A comprehensive cross reference list of our terminals with British Railways catalogue numbers is available here.
Since 1963 our design of terminals have proved reliable, robust and safe for traction applications. When you buy one of our products you acquire our track record of performance and reliability.
Material: Made to our specification from high conductivity copper BS EN 13600 CW004A seamless copper tube. An inspection hole is provided to check cable location prior to crimping.
Finish: Annealed and electro-tin plated – 5 micron minimum.
Identification: The palm of each terminal is stamped with the crimp size code letter and embossed on crimp form after crimping.
Tools: Use Tranect 35T hydraulic crimping press and crimping dies. Please refer to the data table for the appropriate crimp size code letter for the crimping die. Use Tranect ‘Go’ gauge to check each crimp or measure the crimp using the crimp ‘Go’ gauge dimension given on the data table.
To Order: Please specify catalogue number (Cat. No.), bend type (see diagram) and stud size.
