NMD90 Canadian Copper Building Wire

Applications:

NMD90 Canadian Copper Building wire is used to transmit power in construction sites and industrial areas. The electrical wire can be used in ceiling fixtures. Other common uses include lightweight power supply applications and exposed or concealed wiring in dry or wet areas. The electrical cable should not be exposed to mechanical injuries. This cable is used in electrical wiring projects of construction sites, commercial buildings, and industrial areas. It can also be used to supply power as long as the operating temperature does not exceed 900C. It can be installed in conduits or raceways. Other applications of the cable are as specified by the Canadian Electric Code (CEC).

NMD90 Canadian building wire has freeze flex, which allows easy stripping of the cable and additional crack resistance even in a cold-weather setting. The minimum recommended handling temperature is minus 25°C for two-conductor cables and minus 10°C for three-conductor cables (with suitable handling procedures). The maximum conductor temperature is 90°C. The wire is rated 300 volts.

Building Wire Construction:

Conductors:

The cables have a bare bonding wire and stranded soft annealed copper conductors. They are stranded so as to increase the flexibility of the cable and its ability to carry more current. There are either two or three with a drain wire, depending on the type of cable. The drain wire releases excess current in the cable, which ensures safety. Copper conductors are durable and resistant to corrosion, moisture, and impact.

Insulation:

The cable has a white PVC Nylon T90 Nylon insulation with an FT1 rating. The insulation is resistant to ozone, chemicals, radiation, weather, acids, alkalis, impact, abrasion, industrial solvents, oils, and flames.

Features:

• Single compact ACM aluminum conductor with extra thickness of low temperature moisture resisting cross-linked polyethylene (XLPE) insulation
  CSA Spec C22.2 No. 38-05 
  Rated 1000 volts.

• Maximum conductor temperature 90°C.

• Minimum recommended installation temperature minus 40°C (with suitable handling procedures).

• Service entrance above or below ground

• Exposed wiring where exposed to weather with sunlight resistant insulation.
   

  NMD90 cables are available as two- or three-conductor cables with a bare grounding conductor. It is

  manufactured using annealed (soft) copper conductors-compressed standing for stranded conductors; a

  heat-resistant thermoplastic polyvinyl chloride (PVC) insulation and nylon jacket for the individual conductors with a PVC jacket for the overall construction.

  
  Conductors are white, black and red (for 3 conductor cables). Cable jackets are colour coded by size for quick identification in the Table below
