1. Non-Metallic (NM) Cable
Non-metallic cable, also known as Romex, has a plastic cover that protects the wires inside. This type of wiring is used in homes and small buildings. It is easy to install and costs less. However, it cannot be used in wet places or on the exterior of the house. This wiring is good for areas that do not need extra protection from moisture.
2. Conduit Wiring
Conduit wiring is among the most common electrical wiring types in Singapore. The wires are placed inside plastic and metal pipes, which protect the wires from damage. Conduit wiring is used in residential and commercial buildings.
It is equally preferred in all loads because it is safe and long-lasting. Moreover, it is suitable for inside and outside the building. This type of wiring is best for areas that require extra safety and neat installation.
3. Armoured Cable
Armoured cable has a strong metal cover around the wires. This feature protects it against external damage. It is used in places where the cables need extra protection. Factories and underground wiring systems use this type. It is more expensive but very durable. Armoured cables are also used in places with high foot traffic to prevent wear and tear.
4. Twin and Earth Cable
Twin and earth cables have two wires for carrying electricity and one for safety. It is used in homes for lighting and power sockets. This type of wiring is easy to install and provides good protection.
Many electricians prefer this type because it balances cost and safety well. It is widely used in residential electrical work. In residential circuits, it is one of Singapore’s most common types of electrical wiring.
5. Flexible Cable
Flexible cable is soft and bends easily. It is used for devices that are used at different spots within the home. This wiring is safe and long-lasting. It is often found in appliances that require frequent movement. Flexible cables also make installation easier in tight spaces. Therefore, it is ideal for Singapore’s compact homes.
6. Mineral-Insulated Cable
Mineral-insulated cable is made with a copper cover. It is used in places where fire safety is important. This wiring is strong and can work at high temperatures. Due to this feature, it is preferred for hospitals and emergency buildings. It is one of the best choices for fire resistance and is suitable for essential buildings that need extra safety measures.
7. Low Smoke Zero Halogen (LSZH) Cable
LSZH cable does not produce harmful smoke when it burns. It is used in places where safety is important. Therefore, it is mostly used in offices and public buildings. This wiring is good for the environment and keeps people safe during a fire. Many modern buildings now prefer LSZH cables due to their safety benefits. They help reduce toxic fumes in case of an emergency.
8. Underground Wiring
Underground wiring is used to connect buildings to the main power supply. The wires are placed under the ground to keep them safe. This type of wiring is common in cities and housing areas. It prevents accidents and has a longer life.
Underground wiring also improves the look of an area by removing overhead power lines. It is common in modern housing developments and commercial spaces. Although it is more expensive than the overhead line, its benefits make it more favourable in modern societies.
Conclusion
Choosing the right types of electrical wiring is important for safety and efficiency. Each type has its own benefits and understanding them helps in making the right choice. Safe wiring ensures a smooth electrical system in every building. With proper wiring, the risk of electrical faults and accidents is lower. It is always best to get professional advice before selecting a wiring system.
