After the electrical networks and wiring of buildings fall into disrepair after prolonged use, they are dismantled and then disposed of. Cable scrap metal, which can be obtained from junk cars in markham is a highly liquid secondary raw material suitable for the extraction of valuable non-ferrous metals for subsequent processing and smelting of high-quality secondary materials.
Cable scrap is a good opportunity to get high financial income from decommissioned power and installation networks, residuals, unmarketable goods, installation waste. Cable acceptance is of interest to enterprises, organizations and individuals.
Many companies and scrap metal reception centers provide services on a turnkey basis:
carry out the dismantling of electrical networks at the client’s site;
Carry out cutting of large pieces of cable;
Load scrap into transport;
carry out self-delivery.
Buying and selling metal with self-delivery is in demand, because it frees customers from the organizational hassle and financial costs.
Material of conductive cores
Due to the fact that various metals are used in the cable as current-carrying cores, it is a valuable secondary raw material, which is actively bought up by scrap metal companies.
The cable can be recovered in the recycling process:
lead (protective braid);
Nickel and some other metals.
Types of cable waste
The easiest way to classify cable products is by the type of metal used to make the conductive cores. However, in practice, there are a large number of cable grades that differ from each other by purpose, operating conditions, number of conductors, internal construction, materials of braid, insulation, armor. According to the purpose of cable-conductor products are divided into:
The most valuable secondary resource is considered to be power and installation cables, which contain a large amount of nonferrous metal of sufficiently large diameter, suitable for recycling. Thin cores of telephone and control cables are much more difficult to separate from the sheath and extract.
Scrap cable can be cut up before we buy it back. This makes it possible to get high quality chemically pure metal contained in the conductive cores. This is highly prized and brings in a high income for the scrap metal dealer.
However, it is possible to give cable and wires without cutting together with insulation, fillers, braiding of different materials. Despite the fact that the purchase price of such a resource will be lower, but preparing a batch of scrap metal for delivery will take a minimum amount of time and effort and will not require material costs.
Cable cutting is done mechanically or by annealing. These operations are better performed with the help of special equipment available at the collection points. Self-cleaning of conductive cores in unsuitable or home conditions, especially by annealing, often leads to deterioration of metal quality, its integrity, contamination by other substances, loss of weight. In addition, such a process greatly pollutes the environment and can be hazardous to human health.
Scrap cable prices
The demand for scrap cable and wire products is constantly growing, stock quotes are stably high, which has a positive effect on the purchase price.
The price of used cable scrap depends on the metal yield after cutting, taking into account the available technological capabilities. There are two ways to determine its weight:
by reference books describing the characteristics of each cable brand;
By cutting a test sample of a cable from a given batch of scrap metal.
The price lists of scrap metal collection points usually indicate basic prices for the following types of cable:
aluminum electrotech (purified aluminum conductive core);
undecomposed scrap aluminum cable (together with sheath, insulation);
copper “shine” (cleaned from insulation copper cable, wire);
undecomposed scrap of copper cable;
lead cable protective braid.
Large batches of cable scrap are accepted at a higher price. Many companies, in order to attract wholesale customers, perform free self-delivery of this valuable secondary raw material.
