BS flexible metal conduit is a type of electrical conduit that is designed to provide a flexible and durable solution for protecting and routing electrical wiring. The BS standard refers to the British Standard for the product, which specifies the requirements for the design, materials, and testing of flexible metal conduits.

The conduit is typically made of a helically wound, square-locked, or interlocked metal strip, such as galvanized steel or stainless steel, which provides flexibility and strength. It may also have a protective outer covering made of PVC or other materials to enhance its resistance to corrosion and abrasion.

BS flexible metal conduit is available in various sizes and lengths to suit different applications, and it can be used in a wide range of environments, including indoor and outdoor installations. It is commonly used in applications where the wiring needs to be protected and routed in areas that may require flexibility or where there is a risk of mechanical damage or impact.

BS flexible metal conduit is easy to install and requires minimal maintenance. It can be cut to length and bent to follow the contours of the installation area. Additionally, it can be fitted with a range of connectors, such as straight, 90-degree, and 45-degree connectors, to allow for easy connection to other conduits or fittings.

Flexible metal conduit is used in a wide range of applications where electrical wiring needs to be protected and routed in areas that may require flexibility or where there is a risk of mechanical damage or impact. Some common examples include:

1. Industrial installations: Flexible metal conduit is commonly used in industrial applications, such as factories and warehouses, where machinery and equipment may be subject to vibrations, movement, or impact.
2. Commercial buildings: It is also used in commercial buildings, such as offices and shopping centers, to protect electrical wiring in areas where there may be foot traffic or where the conduit needs to be routed around obstacles.
3. Outdoor installations: Flexible metal conduit can be used in outdoor installations, such as for street lighting or underground wiring, where it needs to be protected from moisture and environmental factors.
4. Hazardous environments: It is also used in hazardous environments, such as chemical plants and oil refineries, where it needs to be resistant to chemical exposure and other hazards.
5. Residential installations: Flexible metal conduit can be used in residential installations, such as for wiring in walls or ceilings, where it provides protection for the wiring and allows for flexibility in routing.

Overall, the flexible metal conduit is a versatile solution that can be used in a wide range of applications where protection and flexibility are important considerations for electrical wiring installations.

The BS flexible metal conduit comes in two main types, which are:

1. Square-locked type: This type of conduit is made by helically winding a metal strip and then forming it into a square-shaped tube. The edges of the strip are then interlocked together, creating a strong and flexible conduit. Square-locked BS flexible metal conduit is commonly used in applications where moderate flexibility is required.
2. Interlocked type: This type of conduit is also made by helically winding a metal strip, but instead of forming a square-shaped tube, the edges of the strip are formed into a series of interlocking rings. This creates a more flexible conduit that is suitable for applications where a high level of flexibility is required.

Both types of BS flexible metal conduits are available in a range of sizes and materials, including galvanized steel and stainless steel. They are also available with a variety of coatings and coverings, including PVC, polyethylene, and liquid-tight coatings, to provide additional protection against moisture, chemicals, and other environmental factors.

The choice between square-locked and interlocked BS flexible metal conduit will depend on the specific requirements of the application, including the level of flexibility needed, the type of wiring being used, and the environmental conditions the conduit will be exposed to.

The square-lock and interlock flexible conduit are both produced by profiling steel strips and helically wound to flexible conduit.

The square-lock flexible conduit is designed and produced with a wider pitch that forms a corrugated surface.

The structure of the interlock flexible conduit is more compact and the surface is flat.

The Difference in structure brings different features for these two types of flexible conduit and fulfills requirements from different applications.

&#; The loose structure gives better flexibility and lighter weight to square-lock flexible conduit. That is a benefit for those applications that require small space, limit weight for the whole wiring system, protection for lines at the static position and etc.

&#; Contrarily, the solid structure of interlock flexible conduit offers higher tensile resistance, and anti-twist, and the inner and outer surface is flat so that the wires can be pushed through the overall length smoothly. Interlock flexible conduit is good for wire protection at dynamite positions and in a rough environment.

Depending on the environmental conditions, square-lock, and interlock flexible conduits are also available to be covered with a plastic jacket to meet requirements of water/moisture proof, oil resistant, dustproof and etc. Further demands of abrasion resistance, anti-compression, or EMC resistance can be fulfilled by adding a metal braiding layer to advance the characteristics.
