Long life liquid impervious contact cables with special flexible PVC based covering. The contact clamps are not soldered, they are solderless pressed with an insulated inner conductor as well as with a special liquid resistant outer covering. No other coverings or protective hoses are required. This prevents items from hanging up on other protective elements. The danger of breaking a cable is reduced and the life span is increased. For galvanising barrels having a little access, we have produced a double-insulated contact cable with a split insulation. If desired, we can provide contact cables with extra heat resistant insulation for applications involving high temperatures, dryers etc. Contact cables with contact clamps or different sized connection elements are also available (e.g. 150 mm²). We can produce a number of special versions inexpensively and at short notice.
