Electrical
Cables, collection rails and motors – the questions from electrical installation and control cabinet construction.
In the electric trade, the proceeds can be calculated before the first meter goes into the bag. A NYM-J 3 times 1.5 leads 4.5 square millimeters of copper, which is about 40 grams per meter at approximately 110 grams total weight of the pipe. This results in a conductor share of 35 to 40 percent — exactly the type of cable in which such mantle lines are located. The larger the cross-section, the better the ratio: A NYY 4 by 25 is clearly above, a data line far below.
In cabinet construction, a case is added that regularly costs money: tin-plated collection rails. Blanke copper rail runs as a heavy copper type, a rail with tin coating falls under it, although it looks almost the same. A look at the cut edge separates both.
The last thing that counts is the rhythm for farms with an on-going seizure. Cable residues need volume, not weight: A big bag is full long before 500 kilograms are reached. If you collect coat cable, earth cable, plug cable and bare wire in four containers, you will lose nothing by waiting, because the daily price is valid from the end of the sale.
How many times do you pick up?
From 500 kg, and the clock depends on your level, not on the calendar. With chips from ongoing production, these are often a few weeks, and with carbide it takes longer because the weight is stuck in a bucket. We agree to regular pick-up by arrangement. Depending on the distance between 40 and 350 euros, the pick-up costs are fixed before the trip.
Can I get a credit for the bookkeeping?
Yeah. We charge for commercial deliveries by credit in accordance with § 14 para. 2 VATG, so you do not write an invoice. VAT is not based on the fact that the recipient of the benefit owes the tax on scrap metal, § 13b para. 2 no. 7 VATG. In addition, the weighing slip of the calibrated scale with grade, weight and date; is paid within 24 hours.
What about cable with plugs?
Device and connection cables with plug housing run as Cu plug cable with around 30 percent copper, the lowest cable stage because housing and contact parts are important. You better cut off heavy power supply blocks and roll-on housing. If plug cables are in the bag with mixed cable, we sort them out before weighing.
How do you classify when cables of different design are combined?
By conductor part, not by diameter. An armed earth cable with steel tape falls deeper despite strong cross-section, a slim-coated feed line is clean at 70 percent. If everything is together, we sort it out in front of the scales and weigh each type separately. The actual grade shall be invoiced, not on the date of sale.
Is stripping worth it in your own company?
This is decided on the cross-section: With strong supply lines almost always, because bare ladders as copper Millberry is the highest copper grade. With fine strands and multiple enveloped data lines rarely, there the working time eats the difference. The comparison of daily prices of cables and bare wire shows it in your case.
Do engines have to be disassembled?
Do not disassemble, already decompose: gearboxes, flanged pumps, fan hoods, clamping boxes with electronics and loose cable remnants belong to, remaining stator, rotor and housing. So they run as electric motors without attachments, up to 500 kg per engine. Rust, oil and bolted steel consoles lower the classification, we calculate separated composite lines separately.
