Electrical Conduit

タイトルまたは説明

The strength and versatility of this oft-refined product line maintain its popularity on many a jobsite.
Steel conduit has been in use as a “raceway system” for electrical conductors since the early ***0s. The wall thickness and strength of steel make metal conduit the wiring method recognized as providing the most mechanical protection to the enclosed conductors. An additional benefit of using steel conduit is that the NEC recognizes a properly installed metal conduit system as an equipment grounding conductor.

• Electrical conduit provides very good protection to enclosed conductors from impact, moisture, and chemical vapors.

• Electrical Conduit is widely used to protect cables that carry various amounts of electrical current. For example, Rigid conduit used is used to guard against crushing and shorting of cables. 

• Conduit prevents accidental damage to the insulation.

• Varying numbers, sizes, and types of conductors can be pulled into a conduit, which simplifies design and construction compared to multiple runs of cables or the expense of customized composite cable.

• Wiring systems in buildings may be subject to frequent alterations. Frequent wiring changes are made simpler and safer through the use of electrical conduit, as existing conductors can be withdrawn and new conductors installed, with little disruption along the path of the conduit.

• Metal conduit can be used to shield sensitive circuits from electromagnetic interference, and also can prevent emission of such interference from enclosed power cables.

• When installed with proper sealing fittings, a conduit will not permit the flow of flammable gases and vapors, which provides protection from fire and explosion hazard in areas handling volatile substances.

• Both metal and plastic conduit can be bent at the job site to allow a neat installation without excessive numbers of manufactured fittings. This is particularly advantageous when following irregular or curved building profiles.

• Some types of conduit are approved for direct encasement in concrete. This is commonly used in commercial buildings to allow electrical and communication outlets to be installed in the middle of large open areas.
