    European Mains Power Cables

    We have two European power cables available: C5 ‘clover leaf’ power cable and C13 power cable.

    IEC C13 power cables can be used to power IT equipment, data centers, power distribution devices, home appliances, test equipment, professional food equipment and medical equipment.

    IEC C5 ‘Clover leaf’ power cables can be used to power laptops and mobile projectors.

    A 230 V distribution system will use less conductor material than a 120 V system to deliver a given amount of power because the current, and consequently the resistive loss, is lower.

    In 1899, the Berliner Elektrizitäts-Werke (BEW), a Berlin electrical utility, decided to greatly increase its distribution capacity by switching to 220 V nominal distribution, taking advantage of the higher voltage capability of newly developed metal filament lamps. The company was able to offset the cost of converting the customer’s equipment by the resulting saving in distribution conductors cost. This became the model for electrical distribution in Germany and the rest of Europe and the 220 V system became common.
