SWA 35-10TQ Copper Tube Terminals (35-10T). Specialised Wiring Accessories (SWA) is one of the UK's market leaders when it comes to manufacturing essential cable terminations, fixings, tools, and fastenings. With over 25 years' experience, SWA is a name associated with quality and reliability within the electrical industry. The SWA TQ range of uninsulated, copper tube terminals is manufactured from seamless copper tube to BS EN 12449:1999. Features of the range include: manufactured from 99.5% copper and fully annealed to ensure optimum ductility and prevent deformation such as cracking and splitting when crimping, an inspection window enabling the installer to ensure full and correct insertion of the conductor, and a flared entry to enable a smooth transition from terminal to conductor. Internal barrel diameters suit standard cables as defined in BS 6360. All SWA terminals have both the cable size and hole size identified on the palm, ensuring the selection of the correct tooling and dies. The SWA 35-10TQ is a 35mm copper lug with a 10mm hole.
