Calculation of the copper surcharge
What tell us terms like Copper base and Copper weight?
DEL – German electrolytic copper for purposes of conducting capacity
Cables and conductors are sold at DEL current daily prices for copper. The DEL is the listing for Deutsches Elektrolytkupfer für Leitzwecke (German electrolytic copper for purposes of conducting capacity). It stands for 99,5 % pure copper.
Copper base
The list price of most cables and lines already includes a share of the copper price. It is quoted in € per 100 kgs. Like almost all European cable manufacturing companies Franz Raab GmbH works with a copper base of € 150,00 / 100 kgs for most cables and wires.
Copper weight
The copper weight (the copper value) of a cable or a line is given in kgs.
Copper surcharge
The copper surcharge is the difference between the copper value based on the calculated copper base and the value of the DEL notation of the day. Additional purchasing costs of 1,0 % are added to the notation of the day. The copper surcharge is quoted on our invoices.
Copper surcharge calculation
Formula: Copper surcharge EUR/km=copper weight (kgs/km) x (DEL+1% purchasing costs) – copper base/ 100
| Example: |
|
| MY® 272 Microphone cable LiYDY 2 x 0,22 mm2 | |
| Copper weight/km | 13,00 kgs |
| Copper base | 150,00 EUR/100 kgs |
| DEL | 550,00 EUR/100 kgs |
| 13 kgs/km x | (550,00 EUR + 1%) – 150.00 EUR = | 52,72 EUR/km |
| 100 |
