Draadtype

Draadtype is a Dutch term used to refer to the classification of electrical wires and cables, describing the characteristics that determine their suitability for specific applications. In practice, a draadtype combines information about the conductor, insulation, shielding (if any), and the intended operating conditions.

Conductor and construction. Wires may have solid or stranded conductors. Conductors are typically made of copper or aluminum, with copper being the most common choice for its conductivity and ductility. Some wires use tinned copper for improved corrosion resistance. Stranded conductors are more flexible and commonly used in movable or flexible cords, while solid conductors are favored for fixed installations.

Insulation and jackets. The insulation material protects the conductor and defines safety ratings. Common insulation types include PVC, thermoplastic elastomers, XLPE, and silicone compounds, often paired with an outer jacket for additional protection. Insulation and jackets determine voltage rating, temperature tolerance, chemical resistance, and environmental suitability. Color coding and markings help identify function and compliance with standards.

Shielding and special features. Some draadtypes include shielding (foil or braided) for electrical noise reduction, or special constructions for oil resistance, flame retardance, or high-flex applications. Flexible cords, fixed-installation wires, and control or signal cables represent different families within draadtypes.

Standards and ratings. Draadtypes are defined by national and international standards and must meet specified voltage, temperature, and durability requirements. Selection depends on application, including operating voltage, current-carrying capacity, mechanical stress, and environmental conditions.

Applications and selection. Draadtypes are used in residential wiring, automotive and machinery, industrial systems, and electronics. Correct selection ensures safety, reliability, and regulatory compliance.
