2. Electrical conduit - Wikipedia

   en.wikipedia.org/wiki/Electrical_conduit

   Galvanized rigid conduit (GRC) is galvanized steel tubing, with a tubing wall that is thick enough to allow it to be threaded. Its common applications are in commercial and industrial construction. [1] It is designed to protect wire and connectors. Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may ...

3. Thermoplastic-sheathed cable - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic-sheathed_cable

   A thermoplastic-sheathed cable (TPS) consists of a toughened outer sheath of polyvinyl chloride (PVC) thermoplastic, covering one or more individual annealed copper conductors, themselves insulated with PVC. This type of wiring is commonly used for residential and light commercial construction in many countries.

4. Cable tray - Wikipedia

   en.wikipedia.org/wiki/Cable_tray

   Common cable trays are made of galvanized steel, stainless steel, aluminum, or glass-fiber reinforced plastic. The material for a given application is chosen based on where it will be used. [ 6 ] Galvanized tray may be made of pre-galvanized steel sheet fabricated into tray, or may be hot-dip galvanized after fabrication.

5. Polyvinyl chloride - Wikipedia

   en.wikipedia.org/wiki/Polyvinyl_chloride

   In a fire, PVC can form hydrogen chloride fumes; the chlorine serves to scavenge free radicals, making PVC-coated wires fire retardant. While hydrogen chloride fumes can also pose a health hazard in their own right, it dissolves in moisture and breaks down onto surfaces, particularly in areas where the air is cool enough to breathe, so would ...

6. Welded wire mesh - Wikipedia

   en.wikipedia.org/wiki/Welded_wire_mesh

   PVC coated welded mesh with plastic covering is constructed with galvanized iron wire of high quality. It has PVC powder covering that is processed by an automatic machine. The smooth plastic coating on this corrosion protective wire is attached with a strong adhesive which make increases durability of the wire.

7. Armoured cable - Wikipedia

   en.wikipedia.org/wiki/Armoured_cable

   Bedding: Polyvinyl chloride (PVC) bedding is used to provide a protective boundary between inner and outer layers of the cable. Armour: Steel wire armour provides mechanical protection, which means the cable can withstand higher stresses, be buried directly and used in external or underground projects. [4]
