Copper surcharge = (copper quantity (kg/km) x (DEL + purchasing costs) - copper basis) / 100 The copper quantity shows the weight of the copper in a cable or line and is shown in kg per km. DEL = German Electrolyte Copper for Conducting Purposes and is the exchange listing for 99. The material price for cables and wires is usually based on a copper price of 150,00 EUR/100 kg.

4-2002 IEC 60502-4 Technical parameters:Power frequency withstand voltage:117kV/5mins Partial discharge :45kV<10pCStandard :GB/T12706. Thermal withstand ensures the busbar temperature does not exceed the short-time limit (250 degrees C for copper per IEC 61439-1) during a fault: A >= I x sqrt (t) / k, where k = 143 for copper (or use 13 for Aluminium. Suitable for the high voltage electrical apparatus of power plant, power transformer station at or under 35kV, such as cable branch box, combination transformer and incoming / outgoing line of GIS system. Functional Specification for 15 kV, 25 kV, or 35 kV Underground Distribution Switchgear Functional Specification for 15 kV, 25 kV, or 35 kV Underground Distribution Switchgear Scope This specification applies to three-phase, [select #] - way [select # -source, select # -tap], 50-60 Hz, fully dead. Main keywords for this article are Bus Bars and Bus Ducts Design Requirements, ANSI C37. Used where the presence of oxygen in copper is undesirable, as in certain electronic parts, or. This calculator helps electrical engineers, panel builders, and power system designers to properly size and evaluate bus bars.
