Electrical conduits are used to protect electrical wiring from damage caused by drywall screws, abrasion, or UV rays. They are commonly made of metal, but plastic conduits are also available and widely used. Plastic electrical conduits are typically made from PVC (polyvinyl chloride), a combination of vinyl and plastic. PVC conduits are lightweight, inexpensive, and easy to work with, making them a popular choice for residential and commercial applications. They are also resistant to moisture and corrosion. However, they require an extra grounding conductor due to their non-conductive nature. Other types of plastic conduits include LSZH (Low Smoke Zero Halogen) conduits, which are made from plastics such as PP or PE and offer advantages in terms of reduced smoke and halogen emission during combustion.

PVC conduit is made from polyvinyl chloride
Plastic electrical conduit is made of polyvinyl chloride (PVC). PVC conduit is a combination of vinyl and plastic. It is lightweight and usually lower in cost than other forms of conduits. It is also resistant to moisture and many corrosive substances.
PVC conduit is used primarily in electrical systems. It is used to house wiring and protect wires or cables that are outdoors or exposed. It is also used in residential settings, and some jurisdictions require it over other types of conduits for specific applications.
PVC conduit is available in various sizes and thicknesses, with thin-wall varieties suitable for embedded use in concrete and heavier grades suitable for direct burial and exposed work. It can be heated and bent using special tools and can be joined using PVC solvent glue, which creates a strong bond.
While PVC conduit offers advantages such as lightweight and corrosion resistance, it is not approved for use in plumbing systems due to a lack of pressure testing, which makes leaks likely. It is also not suitable for use in applications where it would be subject to physical damage.
PVC conduit should not be confused with PVC pipe, which is used to carry water and must meet specific safety requirements for flame and temperature resistance. PVC pipe is usually thicker than PVC conduit to withstand higher pressures.

PVC is lightweight and resists moisture and corrosion
Plastic electrical conduit is made of PVC (polyvinyl chloride), which is a combination of vinyl and plastic. PVC conduit is lightweight, moisture-resistant, and resists corrosion.
PVC conduit is a popular alternative to metal conduits, which are typically made of steel or aluminium. Metal conduits are often used in commercial and industrial settings, whereas PVC conduits are more commonly found in residential environments. PVC is lightweight in comparison to steel conduit materials, and it is also usually lower in cost. PVC conduit is available in various sizes and wall thicknesses, with the thin-wall variety suitable only for embedded use in concrete, and heavier grades suitable for direct burial and exposed work.
The plastic material of PVC conduit resists moisture and many corrosive substances. This makes it a good choice for protecting wiring from damage caused by abrasion or drywall screws, which can degrade insulation when wires are run outside. However, because PVC conduit is non-conductive, an extra bonding (grounding) conductor must be pulled into each conduit.
PVC conduit is also flexible and can be cut and joined easily. It can be heated and bent using special heating tools, and joints are made with slip-on solvent-welded connections that set up rapidly and attain full strength within a day. This makes PVC conduit a good option for exterior work, such as with equipment near swimming pools and hot tubs, where its flexibility makes it the only suitable conduit for certain applications.

PVC conduit is used for electrical systems
Polyvinyl chloride (PVC) conduit is a combination of plastic and vinyl. It is a popular alternative to copper piping in plumbing due to its lower cost. However, it is not suitable for plumbing systems that require pressure testing. In contrast, PVC conduit is primarily used in electrical systems as a protective housing for electrical wires, cables, and conductors.
PVC conduit is commonly used in residential electrical systems to route wiring through walls, ceilings, and underground installations. It safeguards wiring from mechanical damage, enhances electrical safety, and enables organised wiring layouts, contributing to improved efficiency and reliability. The conduit's UV resistance makes it suitable for outdoor use, protecting wiring from sunlight degradation.
PVC conduit is also utilised in commercial buildings to facilitate electrical and communication outlets in open areas. It is often installed directly in concrete, providing a neat appearance without requiring excessive manufacturing. The conduit's lightweight property reduces installation labour costs, and its ability to resist moisture and corrosive substances protects wiring in wet environments.
Additionally, PVC conduit serves as an electrical insulator, reducing electromagnetic interference. It helps prevent electrical shorts, grounding issues, and ensures the integrity and safety of electrical systems, particularly in environments with sensitive electronic equipment. The use of PVC conduit enhances system integrity and operational safety by providing a reliable pathway for electrical wiring.
Overall, PVC conduit is a vital component in electrical systems, offering protection, insulation, and safety measures for wiring installations in various residential, commercial, and outdoor applications.

Low Smoke Zero Halogen Conduit is made from plastics such as PP or PE
Plastic electrical conduit comes in many forms, from PVC to Low Smoke Zero Halogen (LSZH) varieties. LSZH conduit is a newer type of electrical conduit that is made from plastics such as PP (polypropylene) or PE (polyethylene).
LSZH conduit is a safer alternative to PVC conduit as it produces a minimal amount of smoke when burning, reducing interference to the visual field during combustion. This is due to the unique material and formula of LSZH conduit, which absorbs heat energy and releases steam when burning.
Another advantage of LSZH conduit is that it does not release hydrogen chloride when burning, reducing the possibility of it being inhaled during combustion. This is because LSZH conduit does not contain halogens, which are elements such as fluorine, chlorine, bromine, and iodine. Halogens are found in many conventional wire and cable materials and can cause severe respiratory harm when burned.
LSZH conduit can also be environmentally friendly, as it does not contain heavy metals like lead, cadmium, chromium, mercury, and other harmful substances. Despite not containing halogen-based flame retardants, LSZH conduit can still achieve the necessary flame retardant ratings by using other types of non-halogenated flame retardants.
LSZH conduit is widely used in public transportation facilities, including the interior wiring and cable protection in vehicles such as airplanes, trains, subways, ships, and buses.

LSZH conduit produces less smoke and toxic fumes than PVC
LSZH conduit, or Low Smoke Zero Halogen Conduit, is a type of plastic electrical conduit that produces less smoke and toxic fumes than PVC conduit. LSZH conduits are made from materials that do not contain halogens, such as chlorine, fluorine, bromine, or iodine.
When exposed to fire, LSZH conduits are designed to emit minimal smoke and no toxic halogen gases. This is in contrast to PVC conduits, which can release harmful gases, such as hydrogen chloride, when burned. The reduction in smoke and toxic fumes provides several benefits, including enhanced visibility during fire incidents, aiding in safe evacuation, and reducing smoke-related damage to sensitive equipment.
The low smoke and halogen-free characteristics of LSZH conduits are achieved through the use of alternative flame-retardant additives in the manufacturing process. These additives, such as aluminum hydroxide, magnesium hydroxide, and phosphorus-based compounds, help suppress flames, absorb heat, and further reduce smoke production. As a result, LSZH conduits have superior fire performance compared to PVC conduits.
In terms of weight, LSZH conduits are also more lightweight than PVC conduits, with an overall weight reduction of 30%-40%. This makes LSZH conduits easier to work with and maximizes the advantages of plastic products. Additionally, LSZH conduits are considered more environmentally friendly than PVC conduits. They are made with halogen-free materials, eliminating the release of hazardous halogenated by-products, and are recyclable, reducing their overall environmental impact.
Overall, the LSZH conduit's ability to produce less smoke and toxic fumes than PVC makes it a safer and more environmentally conscious choice for electrical installations, particularly in enclosed or high-risk environments where fire safety and air quality are critical.
