Range of Conductors
In addition to the standard conductors offered in many electrical cables, Kalestead has developed an extensive range of super-flexible options, examples of which are shown below (resistances are for plain copper wire):

High conductivity plain copper wire to BS4109 is used. Tinned, silver- or nickel- plated copper and specialist alloy conductors are also available. Tinsel (cadmium-free) is offered for communication applications requiring tough, ultra-flexible conductors capable of over 400,000 flex cycles. (Insulation-piercing crimp terminals are best suited to tinsel conductors).
