All HAUPA-articles in the product area "Working under tension" are provided with 2-coloured coating-insulation (where this is technically possible). The multiple insulation layer supports the valid rule VBG4. This demands a test of all tools on externally recognisable damages before beginning of the works. By 2-coloured coating-insulation - the second insulating layer has a yellow contrasting colour - damages become immediately visible.
