Copper Calculation
All prices in our webshop are including copper (full-copper-price).
Copper is an essential part of wires and cables and is listed on the stock exchange. The name DEL is derivated from the German exchange "Deutsche Elektrolytkupfernotiz für Leitzwecke". Based on the official quotation at the LME (London Metal Exchange), the value of the DEL list is calculated every trading day. The standard price for automotive cables is based on a copper value of 150.00 EUR / 100 kg. The webshop will show you the price including copper, based on the actual value of the German exchange. How to calculate from a pricebase copper 150.00 EUR / 100 kg to the DEL price you need to calculate like shown:
copper weight [kg / km] x ( ( medium DEL [EUR / 100 kg] + 1 % procurement costs ) - copper base [EUR / 100 kg] ) / 100
= copper surcharge [EUR / km]
Example Data
| Cable | FLRY 1.00 mm² |
|---|---|
| Copper Weight | 9.60 kg / km |
| DEL | 590.00 EUR / 100 kg |
| Copper Base | 150.00 EUR / 100 kg |
Example Calculation of Copper Surcharge
The total price will be the quoted price in the online shop + copper surcharge (in EUR / km):
9.60 [kg / km] x ( ( 590.00 [EUR / 100 kg] + 5.90 [EUR / 100 kg] ) - 150.00 [EUR / 100 kg] ) / 100
= 42.81 [EUR / km]
