Indoor electrical conduit is a pipe and pipe fitting used to protect and lay insulated wires and cables. It usually has a circular cross-section. Its main function is to lay wires and cables inside buildings to prevent them from being piled up together and causing danger.
Understanding the role of indoor electrical conduit
The main functions of indoor electrical conduit include ensuring wiring safety, avoiding wire damage, flame retardant, convenient wire replacement, and heat dissipation. These functions ensure the stability and safety of the electrical system and prevent potential safety hazards.
1. Ensuring wiring safety is the primary function of electrical conduits. When decorating a home, using PVC electrical conduit pipe or metal pipe for wiring can ensure the safety of power cord placement and avoid direct exposure of wires to the outside and damage. This practice complies with the requirements of national electrical engineering specifications, especially when laying concealed wires, wire conduit wiring must be used to ensure wiring safety.
2. Avoiding wire damage is one of the important functions of conduits. During the wiring process, wires may be pulled or scratched. If they are protected by wire conduits, this situation will be greatly reduced. In addition, the wires are buried directly in concrete, and the silicates in the cement will corrode the insulation layer of the wires, while the wire tube can prevent this from happening.
3. Flame retardant effect is also an important feature of the conduit. Modern wire tubes are generally flame retardant. In case of a short circuit causing the insulation layer of the wire to catch fire, the wire tube can prevent the spread of the fire, thereby avoiding greater disasters.
4. Convenient wire replacement is another consideration in the design of the conduit. Using wire tubes for wiring can make line maintenance and replacement easier. Whether it is an open tube or a concealed tube, it can be replaced without damaging the wall.
5. Heat dissipation is also an important function of the conduit. The load capacity is taken into consideration when designing the cross-section of the wire, leaving ample space. The wire tube can help dissipate heat and reduce the problem of overheating of the wire.
Electrical conduit type
PVC pipe
PVC pipe is a conduit with polyvinyl chloride as the main raw material, which has the characteristics of light weight, insulation, flame retardant, durability, and corrosion resistance. It is widely used in indoor construction and residential electrical wiring projects. Due to its environmental quality and the convenience of prefabricated installation, it is particularly suitable for concealed burial in concrete and is not damaged by pressure.
KBG pipe
KBG pipe is a buckled thin-walled steel pipe made of high-quality thin-walled sheet material. It has the advantages of high tensile strength, good wear resistance, corrosion resistance, and low price. It is suitable for electrical line installation projects such as suspended ceilings and exposed installations, especially for temporary or short-term buildings.
JDG pipe
JDG pipe is a sleeve-type galvanized steel conduit with high temperature and corrosion resistance. It is suitable for pipeline systems in highly corrosive and high-temperature environments, such as chemical, petroleum, natural gas, and other fields. Its installation cost is high and difficult, and it is often installed by welding.
SC pipe
SC pipe is a thick-walled galvanized steel pipe with high strength, light weight, fire resistance and good shielding performance. It is mainly used for concealed outdoor cable piping in the fields of construction, machinery, chemical industry, electricity, etc. The construction process is complicated and requires anti-corrosion and grounding treatment.
What factors should be considered when selecting an electrical conduit?
1. Material selection: Electrical conduits should be made of materials with good electrical properties, corrosion resistance, high-temperature resistance, and cold resistance. Common materials include polyvinyl chloride (PVC), HDPE Electrical Conduit, etc. These materials have good insulation and conductivity properties and can ensure the safe operation of the electrical system.
2. Pipe diameter and wall thickness: The pipe diameter should be determined according to the specifications of the wires and cables to be protected to ensure sufficient space inside the pipeline. The wall thickness should comply with relevant standards to ensure that the conduit has sufficient mechanical strength and durability.
3. Fixing method: Choose a conduit that is easy to fix and install for easy construction and maintenance. Ensure that the conduit is stable and reliable in various installation environments.
