Flexible metal cable conduits China
, is heavy-duty galvanized steel tubing that is installed with threaded fittings. It is typically used outdoors to provide protection from damage and can also provide structural support for electrical cables, panels, and other equipment. Flexible metal conduit is sold in 10- and 20-foot lengths and has threads on both ends.
There are two different wall thicknesses for flexible metal conduits. The thicker flexible metal conduit is a full wall, while the thinner wall product is a reduced diameter flexible metal conduit. The whole wall is stronger and is specified where the code requires additional mechanical protection.
By analyzing the wiring, you can determine when to use a flexible metal conduit instead of a rigid conduit. Flexible metal conduits typically range in diameter from 3/8 to 4 inches, but are typically ½ to 3/4 inches. It is mainly used where rigid catheters are difficult to bend because flexible catheters can bend.
Although flexible conduits are easier to work with than rigid conduits, it offers less protection for the conductors it carries. Bending a rigid conduit can be an arduous task so it is often preferable to opt for the flexible variety. Being a metal conduit, it has an advantage over PVC conduits which cannot bend. It may also serve as the grounding path although some local codes may require that you also run a green grounding wire.
As a, let us tell you the Basics of flexible metal conduit.
Flexible metal conduits are made from steel or aluminum by coiling a self-interlocking ribbed strip of the metal. This forms a tube. The diameter of this tube can vary and different end applications call for different diameter tubes. Wires are pulled through this tube and are thereby protected from damage, both internal and external.
