How To Choose A Better Cable Manufacturer When Buying Cables

How to choose the right wire and cable manufacturers? Many people do not understand this, I will explain in detail below, I believe that you will know after reading.

If we want to choose a wire and cable manufacturer, we need to make a price comparison. Each manufacturer produces a certain difference in the price of wire and cable, we need to see which manufacturer is more cost-effective, choose a cost-effective manufacturers more cost-effective. How to choose the right wire and cable manufacturers?

You also need to compare the material, you can choose according to the model and specifications of the wire and cable you need to buy, but in fact the material is also very important. If the choice of raw materials is poor, the quality of the production of wire and cable is also poor.

It is necessary to know the production machinery and equipment of the wire and cable manufacturer, especially for those who order large quantities, because the integrity of the equipment determines the production capacity, quality and stability of the wire and cable, so this is an important point to consider.

We must determine whether the wire and cable manufacturer has a good after-sales service. Although wire and cable products are not easily damaged during shipping, if there are problems such as broken wires and lack of length when used, the manufacturer still needs to be able to solve these problems perfectly, so it is also very important to find a wire and cable manufacturer with better after-sales service.

Finally, when you receive the goods, you must check and inspect them carefully to see if the quantity of the wire and cable matches the order, if the quality is complete, and to check if there are any obvious defects in the quality, if there are any deviations in the model specifications, and a series of other regular acceptance processes.

Wire and cable manufacturers to produce aluminum alloy cable is aluminum alloy material as the conductor, the use of special roll forming type wire stranding production process and annealing treatment and other advanced technology to invent and create a new material power cable. Cable manufacturers produce aluminum alloy cable when each process needs to pay attention to what?

1、Aluminum alloy cable with interlocking armor

Aluminum alloy with interlocking armor is a special single-layer armor structure. Its cable manufacturer after pre-pressing aluminum alloy belt into "S" type surface, aluminum alloy cable conductor as the center clockwise wrapped in the conductor outside, and interlocked, forming a layer of self-locking armor protection layer.

At present, aluminum alloy cable armor belt is generally made of 5000 series aluminum alloy belt, which has good mechanical properties and high fatigue strength, and also has excellent corrosion resistance.

In the process of chain armor of aluminum alloy cable, in addition to the production equipment factor, the performance, shape, size and so on of the selected alloy belt are the technical key. The national standard aluminum alloy cable requires the armor layer to be uniform in pitch, even and flat, without cracks and can bear certain pressure.

2, Aluminum alloy cable conductor annealing

Aluminum alloy cable conductor annealing process to follow the following three principles: annealing temperature, time, annealing amount.

Annealing temperature: annealing temperature should be higher than the aluminum alloy liquid recrystallization temperature.

Annealing time: under the condition of ensuring complete recrystallization of the conductor, try to reduce the annealing time to improve the production efficiency of aluminum alloy cables and reduce energy consumption.

Annealing volume: the amount of one-time annealing of aluminum alloy cable conductor annealing performance has a direct impact on the one-time annealing volume should not be too much, cable manufacturers should be based on the performance of the annealing furnace and the production of aluminum alloy cable conductor model to determine the amount of one-time annealing.

3, Aluminum alloy cable conductor continuous rolling

Aluminum alloy conductor performance indicators, is to determine the electrical properties of aluminum alloy cable, mechanical properties to meet the standard decisive elements, therefore, in the aluminum alloy conductor rolling process, the following points should be noted:

1. To clarify the amount of aluminum rods, intermediate alloys and special additives used, the amount should not be too much or too little.

2. The temperature of aluminum alloy rod is higher after melting, and the plasticity is more difficult, so the pressure of cooling water should be adjusted at any time to help the aluminum liquid crystallize and form.

3. When rolling, we should strictly control the tensile strength and elongation of the aluminum rod, so as to facilitate the subsequent processes.

4, Aluminum alloy cable conductor tightening

Aluminum alloy cable conductor using a special compression process, cable manufacturers to control the production of aluminum alloy cable outside diameter, the compression factor is generally controlled at about 0.92. At the same time, through the conductor tight compression, to make up for the shortage of aluminum alloy conductors compared with copper conductors in the volume of conductivity. This will make the stranded aluminum core and the solid copper conductor have comparable performance index, obviously reduce the outer diameter of the aluminum alloy cable, and improve the conductivity of the aluminum alloy cable.

In the process of tightening the aluminum alloy cable conductor, we should use the appropriate mold and maintain a uniform stranding speed to ensure the uniform shape of the aluminum alloy cable conductor.

According to the cable manufacturer's staff introduction of aluminum alloy cable performance, not only with the performance of raw materials, but also with the production process, production equipment and even production environment have a certain relationship. Order high-quality cable recognized Dongguan City, XSD cable.

Well, the above is the introduction of "how to choose a better cable manufacturer when buying cables", I hope it can help you! We recommend to continue to pay attention to XSD Cable, to learn more information.
