Types of Wire and Cable in Commercial Buildings

The electrical wiring system selection and placement is crucial in modern commercial buildings. Wiring has different pros and cons, thus selecting the most appropriate one can not only improve safety and functionality but also decrease maintenance costs. This paper will deeply address several kinds of wires which are commonly used on commercial buildings along with their corresponding scenarios.

I. Installation of Electrical Wiring

Installation cables are mainly used for indoor concealed sockets, lights, and power supply wiring. The material of installation wire is mainly divided into PVC and LSZH. The corresponding models are H05V-U and H07Z1-K. The PVC material of the wire is economical and practical. However, with the frequent occurrence of fires in recent years, and the deaths caused by toxic fumes accounting for the majority, more builders are choosing low-smoke halogen-free type H07Z1-K installation wire. This type of wire, with good fire prevention and low smoke and halogen-free characteristics, effectively reduces casualties in the event of a fire.

II. Telecommunications and Fire Alarm Cables

Telecommunications and fire alarm cables are mainly used for transmitting telephone network signals as well as emergency alarm functions. They usually have anti-interference and fire prevention properties. The material of these cables is mainly classified into PVC LSZH with aluminum foil shielding. Common fire alarm cable models are LiYCY, UL1424, and JE-H(St)H.

III. Energy and Power Cables

Energy and power cables with a voltage of usually 0.6/1kV are mainly used for building buses and household line power supply. These cables are usually larger in size and are sometimes buried under concrete, so they are often armored. Common types are NYY, N2XY, and NYCY.

IV. Fiber Optic Cables

Fiber optic cables are used for transmitting data via optical signals.

V. Bus Cables

Bus cables are used for data communication between devices and control signal transmission cables, suitable for automation systems in buildings. Common cable models are KNX. These cables can be used to control and detect the building’s lighting, air conditioning, and security systems.

VI. Network Cables

This type of cable is used for computer routers and Internet connections. Common models include Cat5e, Cat6, and Cat6a. As the most basic network cables, these cables are more likely to receive electromagnetic signal interference.

Conclusion

It is essential to select the right kind of electrical wiring for commercial structures as it ensures safety, efficiency, and economy. Every cable type has specific roles ranging from power supply to data transmission. Being aware about these cables’ behaviors and uses can inform choices made during construction to maintain a good building infrastructure level.
