Copper conductors are made according to customer’s design and drawing. ME-Metals & Technologies processes and machines the profiles. If necessary, we weld or braze the profiles.
Depending on the current strengths, and/or the type and number of anodes, the cross-section of the copper profile is determined. ME-Metals & Technologies calculates the most efficient cross-section of the copper profiles on the basis of 2 Amp per mm².
If desired and applicable, copper profiles can be provided with a suitable heat shrink tubing, which serves as electrical shielding.
CuTi Power Lines & Bus Bars
Titanium sheathed copper power leads are available in many sizes and designs. The copper-titanium is extruded, which gives a best bond. The result is an optimal power supply.
Compared to conventional loose cladding, our bus bars offer significant advantages.
Important differences are:
- High heat transfer
- Excellent electrical conductivity
- High degree of design flexibility
A further improvement is achieved by using so-called submerged bus bars, in which the current conductor is submerged. This design provides an improvement with regard to current transfer, contact resistance, heat development, but certainly also – when using anode baskets – with regard to the filling of the baskets!
ME-CuTi power leads and bus bars can be provided with mounting holes for mounting the anode plates and/or end caps.
We have profiles in different sizes in stock for the galvanic and electrochemical industry. The standard length is 3100mm.
Full Titanium Power Lines
For certain applications, if the current strengths are low, full-material titanium profiles are also used. Titanium has a significantly lower electrical conductivity, but this is often no problem for low currents.
Full material We have titanium power liners in stock – as sheet material – in all thicknesses, and are usually cut to size by means of water cutting. We tailor-make your power supply, possibly with suitable anodes, according to the drawing.
AlTi are titanium-coated aluminum profiles, which are often used in the production of suspension racks. Our AlTi profiles are extruded, and have a good electrical bond between the Al and Ti materials.
Why Aluminum vs. Copper?
- Because the aluminum is lighter in weight, which is preferred for hanging racks
- Because in the event of leakages from the profiles, copper would surround the bath, which pollutes the bath, and replacement is necessary.
- With aluminum this is less critical.
- We have AlTi profiles in stock in dimensions dia 19mm x 3000mm.
- These can be made to measure, possibly fitted with end caps.
CuTi hockey sticks
For the well-known Gravitel – EGL anodes, ME-CuTi current conductors are produced according to a special design, better known as hockey sticks. On each anode, with dimensions of approximately 950 x 2000 mm, 10 or 12 current conductors are mounted, which distribute an optimal current over the plate.
The relevant bus bars are normally available in 2 versions. Diameter 63 x 25mm and diameter 23 x 42mm.
CuTi wire anodes
ME-CuTi wire anodes are often used as an anode for cathodic protection or as a current conductor for an auxiliary anode. A good power distribution is often an important factor. The titanium sheathed copper wire ensures a low electrical resistance, so that long wires can be used.
The ME-CuTi wires are -currently- available in 2 sizes, diameter 1,5mm and 3,0mm. Other diameters are on request. The wires can be platinized (MEPLA – coating).
Solid material Titanium or Niobium wires, without copper core, are also available on request. See also KB – cathodic protection.
The most important features of ME-CuTi wire anodes:
- Light in weight
- Best power distribution
- A low electrical resistance
Explosive Clad Copper Plates
Explosion cladding is a process in which 2 metals are clad together by means of an explosion. The impact of the explosive produces energy to bond the metal surfaces together under high pressure.
Explosive cladding is a cold process that takes place at room temperature. It is a method of welding metals that cannot be welded with conventional processes, such as titanium-steel, aluminum-steel and aluminum-copper. It can also be used to weld compatible metals, such as stainless steel and nickel alloys, to steel.
The metals to be clad are typically stainless steel, duplex steel, titanium, aluminum, copper, copper alloys, nickel, nickel alloys, tantalum and zirconium.
In the electroplating world, an explosion clad plate is used when the currents are too high to make an extrusive profile. A Titanium Grade 1 plate, usually 3 to 4 mm, is then clad on a thicker copper plate, often with a thickness of 25 mm. A water profile is then cut from the explosion-clad plate, which already serves as the basis for the power supply; the remaining free copper is provided with a titanium lining all around. In this way, currents up to a range from 4000 to 12000 Amp. can be realized.
Another application for an explosion clad plate is in equipment construction, where a tube plate for a heat exchanger is often made from a combination of steel with a higher corrosion-resistant material. In this situation, lower costs are usually the deciding factor.
Flexible copper connections – Litzen
With Litz current conductors, the core consists of a bundle of thin copper wires that lie against each other without insulation and are enclosed together by an insulating layer. The wires can be tin-plated for better solderability and better resistance to corrosion. The insulating jacket may be made of soft PVC, Teflon, nylon or other plastic.
The advantage of a core made of many loose wires is that the wire has a much higher flexibility than wire with a solid core, that the wire breaks much less quickly and that the wire can handle relatively more current at higher frequencies, because there is much more wire surface. The disadvantage of this core is that when clamping in a cable clamp, the wires do not all remain under the clamping screw. This can be remedied by using end sleeves or cable eyes. In this, all wires are pressed together in a metal sleeve.
The more wires there are in the core, the smoother the cable is. In particular, the core of test leads sometimes consists of 600 super-thin copper wires. A common designation for the composition of litz is number of wires × diameter of each wire, for example: 10 × 0.1 or 48 × 0.3.
An earth wire, also called litz wire or litz wire, is used, among other things, in electrical engineering to ground specific components. The litz wire consists of a woven bundle of (copper) wires that lie (un)insulated against each other. Whether or not covered by an insulating layer. The so-called insulated earth wire.
An Earth wire is characterized by:
- Customer-specific products.
- Red and/or tinned copper.
- Many diameters and sizes available.
- Standard ground wire on a roll.
- Equipped with cable lug
Available with and without insulation.
