Factors to consider when buying wires and cables
As wires and cables are the prime carriers of electricity, they are needed in industries across all sectors. Therefore, when you have to buy wires and cables, extra attention must be paid. If you are planning to buy cables and wires, here are some important factors to consider:
1. Types of Wires and cables: The first and foremost thing that you should know about wires and cables is that there are different types of cables that are designed for different applications and operating conditions. Some of the common cable types include power cables, communication cables, overhead cables, and underground cables. To select the appropriate wires and cables, you should know the cable construction, characteristics, and ratings for different applications.
2. Quality of wires and cables: Do not let the price be the sole deciding factor rather make sure the conduction capacity, thickness, and insulation of wires and cables are adequate.
3. Check wire insulation
PVC, PE, ECTFE, PVDF, and Nylon are some insulation materials that are used to prevent electrical leakage. They prevent the wire’s electric current from coming into contact with other conductors and preserve the integrity of the wire by protecting against water and heat. The safety and effectiveness of the wire depend on its insulation. When you buy cables, make sure that the insulation material is appropriate for the application.
4. Pick the correct size: Three factors that are important for selecting the cable size are:
- Current carrying capacity: The current carrying capacity of a cable is based on its thermal heating.
- Voltage regulation: It is the ability of a cable to provide constant voltage over a wide range of load conditions.
- Short circuit rating: It is based upon the circuit opening time for short circuit conditions.
These factors should be assessed before choosing a cable size. Overlooking any of these factors can result in short circuits and overloading that can cause electric shock and even electrocution. Not just that, it can trigger an electric fire that endangers your property.
