and underground and submarine HVDC cable systems.

Improving on brass Erodex UK Ltd, a supplier of EDM wire and wear parts, has introduced Gapstar One, describing it as “the fastest EDM speed wire available in the UK”. The wire was developed by Berkenhoff GmbH and is marketed under the Bedra brand. Brendan Kelly, a technical sales engineer at Erodex, said: “As well as increasing speeds by 40 to 60 percent, compared to standard brass wire, and typically more than 10 percent compared to our Boline H product, users will also benefit from increased feed rates - in both rough and skim cuts - without necessarily adjusting current settings. “A further benefit is the reduced wear on wire guides and power contacts, reducing both downtime and costs; and thanks to the newly developed Trimpac coating, a finish of Ra0 .25µm can be expected, along with increased stiffness and straightness for auto threading.” Gapstar One is available with tensile strengths of 900N/mm 2 and 500N/mm 2 , and is compatible with all brands of machines. Kelly added: “While Gapstar One costs more than brass wire, significantly increased
