What is Wire?
Wire is a device that acts as the medium carrying electrical current from the power source to the point of use. The conductor is made from materials with good electrical conductivity and heat resistance, such as copper and aluminum, to help current flow efficiently.
Components of Wire
Each wire consists of 3 main parts that work together so that current flows safely and efficiently.
1. Conductor
The conductor transmits the electrical current. The material used must have low electrical resistance and good conductivity, so that current flows easily. Popular conductor materials include copper and aluminum.
2. Insulation
Insulation is the material covering the conductor, with high resistance to electrical current, functioning to prevent current from flowing to other parts that could cause danger, helping reduce the risk of electric shock, leakage, or short circuit. General wire insulation is made from PVC (Polyvinylchloride) or XLPE (Cross-Linked Polyethylene).
3. Outer sheath (Sheath)
The outer sheath is the outermost layer of the wire, functioning to protect the wire from installation and the environment where it is installed, such as impact, compression, abrasion, or corrosion. Popular sheath materials include PVC (Polyvinylchloride), PE (Polyethylene), and LSHF (Low Smoke Halogen Free).
Types of Wire By voltage rating
Each type of wire is designed to suit a different voltage, so choosing wire by voltage rating helps make the electrical system safe and efficient. It is divided into 2 types:
Wire Low Voltage (Low Voltage Power Cable)
Low-voltage wire is designed for use with voltage not exceeding 750 volts, with copper or aluminum conductors, covered with insulation that prevents current leakage, such as PVC or XLPE, suitable for installation inside buildings, residences, and general electrical systems in Thailand.
Wire High Voltage (High Voltage Power Cable)
High-voltage wire can carry voltage from 1–36 kV. It is a large, multi-core stranded cable, with the conductor covered in high-quality insulation to support high voltage, suitable for high-voltage electrical work, such as supplying power from a substation to a factory or large building.
Types of Wire By conductor material
The conductor material affects the strength, weight, and conductivity of the cable. Choosing wire by conductor must also match the nature of the work and installation.
- copper wire has high strength and conductivity, making it suitable for general installation both inside buildings and underground (Underground Cable). Although copper wire is heavier and more expensive than aluminum wire, its advantages are durability and high performance.
- Aluminum Wire has lower conductivity than copper wire, but its advantages are light weight and economical price, so it is popular for overhead installation, such as outdoor wiring, or wiring work that needs to reduce cable weight.
Guidelines for choosing high-quality wire for contractors
Choosing wire for building and factory projects must take into account quality, materials, and safety standards, so that installation is efficient and reduces long-term problems. For contractors or buyers, the following key points should be considered:
- Type of wire by voltage : Choose low-voltage or high-voltage wire to suit the electrical system of the building or factory
- Conductor material : Copper wire provides high conductivity and is suitable for installation in buildings or underground, while aluminum wire is suitable for overhead work or outdoor work requiring light weight and low cost.
- Standards and certification : Make sure the wire you buy meets TIS or international standards, for safety and confidence in installation.
- Length and number of cores : Calculate appropriately for the project to reduce losses and save costs
- Service and delivery from the distributor : Choose a distributor that offers wholesale wire service, so you can buy at good value, as well as having experts to advise on choosing wire for the project.
Choosing the right wire not only helps the project be completed to standard, but also helps reduce future maintenance problems and increases the satisfaction of the contractor’s customers.
