Insulated ferrules

Do you need insulated ferrules? WKK supplies insulated ferrules in many sizes, colors and packaging units. The products consist of a tube and an insulation sleeve. The tube is made of copper and the insulation sleeve is made of polypropylene. In addition, WKK also supplies a twin (double) insulated version. The products meet the DIN 46228/4 standard. A ferrule ensures that the electrical contact between copper wires in the core of a cable and a mounting clamp is optimal. In addition to insulated products, we also sell uninsulated ferrules, assortments and a crimping tool.
