Brass Cable Glands manufacture 4-Hole Transformer Terminals from 99 .5% copper and fully annealed to ensure optimum ductility to avoid severe deformation such as cracking and splitting when crimped. Terminals are available with an inspection window which enables the user to ensure full and correct insertion of the conductor and a flared entry ensures a smooth transition from terminal to conductor. Internal barrel diameters suit standard cables as defined in BS 6360. All SWA terminals are identified on the palm with cable size (and stud hole size) to ensure correct selection of the appropriate tool and dies.
