When it comes to choosing the proper Copper Electric Cables, you must get confused about the fact that you have to choose them. So, for that, you should have a look at this blog, where you will get familiar with the essential tips that you should remember to have a preferable result for yourself & will not make any mistakes.
Then, without any further delay, jump in & learn essential tips on how to select the most appropriate copper electric cables for your needs.
1. Understand Your Electrical Load Requirements
The initial step in copper cable selection is to know how much electrical load it has to carry. The electrical load is the total current passing through the cable that will be carried.
This is mostly presented in amperes (A). Copper cables are sold in different gauges (or cross-sectional areas) that refer to their thickness. Selecting the right size of cable that can bear the electrical load without getting too hot is the main thing to consider. If the load exceeds the cable size limits, overheating may occur, insulation damage can result, and even fire hazards may be created. The first step is to calculate the current and then choose a cable that has a cross-sectional area that is equal to or greater than that value.
2. Consider the Installation Environment
Also, it is the environment where the cable will be installed that is the most important factor to take into account. Apart from that, different surroundings affect the cable’s durability and performance in different ways. For instance, the appliance is going to be installed outdoors, and the cable is required to be UV-ray moisture and temperature-tolerant. On the other hand, when installing cables indoors, you may not have to follow such strict specifications.
In the case of corrosive atmospheres, which are usually industrial settings with exposure to chemicals or saltwater, it is recommended to use copper cables with suitable insulation that can endure these extreme conditions. Cables installed underground should be armored to shield them from physical damage.
3. Pay Attention to Cable Insulation
Insulation is the material that covers the copper conductor in a cable and offers protection against electrical shocks and environmental damage. The insulation used on a cable determines its elasticity, temperature resistance, and chemical and moisture reactions.
Below are some of the common types of insulation materials:
- PVC (Polyvinyl Chloride): PVC has become the most popular insulation material due to its flexibility, low price, and good electrical insulating properties. Nevertheless, PVC has some limitations and low-temperature ratings that might make it unsuitable for high-temperature environments.
- XLPE (cross-linked polyethylene): XLPE insulation’s features include a high-temperature rating, greater mechanical strength, and better resistance to chemicals and moisture. It is preferable for those who need a cable with longer durability and heat resistance.
- Rubber: Rubber insulation provides excellent flexibility and is commonly used in environments where cables need to withstand harsh physical conditions, such as in mining or heavy-duty industrial applications.
Selecting the appropriate insulation material based on the installation environment and application will ensure the longevity and reliability of the copper cable.
4. Consider the Cable’s Voltage Rating
The voltage rating of the cable tells us the maximum voltage that the cable can handle safely. One must opt for a copper cable that has a voltage rating equal to or greater than the system’s operation voltage. A cable with a voltage rating less than the required one can suffer from insulation breakdown, short circuits, and even fire hazards.
Copper cable is commonly used for:
- Low Voltage (LV): These cables have a voltage rating of up to 1,000 volts. Hence, they are used mainly in residential & commercial electrical installations.
- Medium Voltage (MV): Medium voltage cables usually fall within the range of 1,000V to 35,000V and are applicable in industrial and utility services.
- High Voltage (HV): High voltage cables are rated for voltages over 35,000 volts and are used in power transmission and distribution networks.
Ensure that the cable’s voltage rating aligns with the requirements of your electrical system to avoid potential risks and ensure safe operation.
5. Factor in Cable Flexibility and Durability
Copper cable flexibility is of major importance if it is going to be bent or moved often. Flexible cables are the best ones to install and are least likely to be ruined during this process. They are the best for functions such as home wiring, portable appliances, and machinery with moving parts.
Durability is another essential feature, mostly in surrounding conditions where the cable could be subjected to physical stress, abrasion, or extreme weather. In these situations, it is better to use cables that have reinforced insulation or protective sheaths, such as armored cables, which are more resistant to mechanical damage.
