Conduit

Conduits are tubes used to protect and house electrical wires. They are made of materials such as plastic, steel, galvanised steel, nylon, PVC, PP, and steel spring wires. Conduits are utilised to protect wires in building and structural applications; they also protect individuals who come into contact with them.

Types of Conduits Available

Some conduits are made of metal, while others are made of flexible PVC. While rigid conduits are ideal for rugged outdoor environments, flexible conduits are easier to rout but are more prone to physical stress.

Flexible Conduits

Typically made of galvanised steel or aluminum, this type of conduit offers excellent flexibility for routing around obstacles or connecting moving equipment, and is often used where rigid conduits are impractical. Flexible Metal Conduits (FMC) and Liquid-Tight Flexible Metal Conduits (LFMC) are common subtypes of flexible conduits.

PVC Electrical Conduits

Constructed from rigid polyvinyl chloride, this lightweight and corrosion-resistant conduit is commonly used for underground, concrete-encased, or outdoor applications due to its non-conductive properties and durability. Rigid PVC conduits and Electrical Non-Metallic Tubings (ENTs) are subtypes of PVC electrical conduits.

Metal Conduits

Metal conduits are made from materials like galvanised steel (EMT, IMC, RMC) or aluminum. They provide robust protection against physical damage and electromagnetic interference and are widely used in commercial and industrial settings.

Plastic Conduits

Generally refers to conduits made from various plastic polymers like PVC or HDPE. They are lightweight, corrosion-resistant, and easy to install. Plastic conduits are often found in residential and light commercial applications.

PVC Flex Conduit / Flexible PVC Conduits

Made from flexible polyvinyl chloride, this conduit is used in applications requiring frequent bending or movement, offering good moisture resistance and often found in damp locations, or used to connect motors and other equipment.

Benefits of Using Electrical Conduits

Safe and reliable wiring

Electrical conduits provide a safe and secure path for electrical wires. It encloses and protects the wires from moisture, heat and physical damage.

Moisture protection

Electrical conduits in humid environments are constructed from moisture-resistant materials. They make it possible for power to be routed through bathrooms and kitchens.

Long-term durability

Electrical conduits are ideal for use in long-term installations. They are made to withstand the wear and tear of daily use over time.

Ease of installation

Electrical conduits are relatively easy to install. Conduits can be cut to size and bent to fit around corners, making them suitable for a wide range of applications.

Cost-effective

Electrical conduits are cost-effective solutions for housing your wires, with lightweight options like rigid PVC and thermosetting resin conduits being the most affordable options. They are widely available and good for both residential and commercial installations.

How Electrical Conduits Work

Electrical conduits act as protective sleeves that shield wires and cables from various forms of damage and environmental exposure. They guard against impact, abrasion, and crush damage. They also protect wiring systems from environmental threats such as moisture, corrosive chemicals, UV radiation and extreme temperatures. In the case of fire-rated electrical conduits, they can protect electrical wiring and even prevent the spread of fire.

How To Choose The Right Conduit

Choosing the right electrical conduit for your application demands a critical evaluation of the installation environment and the material properties that may be required. Key considerations include exposure to moisture, chemicals, UV radiation, and extreme temperatures, as well as the need for protection against impact or crushing, fire resistance, and electrical insulation.

For example, high temperature applications may require the use of galvanised steel conduits with high mechanical strength and low fire hazards. Thanks to their ability to withstand temperatures from -50°C to +300°C, they are best suited for deployment in lighting and underfloor heating installations.

Common Applications

Electrical conduits are essential in various settings for the systematic protection and organisation of electrical wiring.

Residential Buildings

PVC and High-Density Polyethylene (HDPEs) conduits are used within walls and ceilings to protect household wiring from physical damage, moisture, and pests, ensuring safety and longevity of the electrical system.

Commercial Spaces

Electrical Metallic Tubings (EMT) and Intermediate Metal Conduits (IMC) are used in offices, retail stores, and public buildings, to route and protect electrical and data cables. This helps to maintain an organised appearance, simplifying maintenance, and meeting safety codes for high-traffic areas.

Industrial Facilities

Factories, warehouses, and production plants utilise heavy-duty Galvanised Rigid Conduits to shield electrical wiring from harsh environmental conditions, chemicals, extreme temperatures, physical impacts, and electromagnetic interference.

Outdoor and Underground Installations

Electrical Metallic Conduits (EMT) and Rigid Metal Conduits (RMC) are used for street lighting, landscape wiring, or underground utility lines. They provide crucial protection against weather elements, UV radiation, moisture, and ground disturbances, ensuring reliable power delivery.

**Hazardous Locations **

In areas with flammable gases or vapours, specialised conduits are employed to prevent ignition by containing electrical arcs or sparks, significantly reducing fire and explosion risks.
