Frequently Asked Questions - XHHW-2 / RW90 Copper Building Wire Conductor

 

What does the letters “XHHW” and “RW90” mean?

These are acronyms which describes the characteristics and qualities of the conductor. The initials stand for “Cross-Linked High Heat Water Resistant” which means that the insulation of the wire has all the above mentioned properties. RW90 stands for rubber insulation or rubber-like insulation that can be used in wet and dry conditions. The “90” stands for the maximum temperature at which the conductor can behave normally which in this case is 900C.

 

What is the voltage rating of the XHHW-2 / RW90 Copper Building Wire Conductor?

The voltage rating is 600V and it is of type XLPE low voltage power.

 

What is the insulation of the XHHW-2 / RW90 Conductor made of?

The insulation is made of Cross-linked Polyethylene (XLPE) which is flame-retardant, which means that it will not spread the fire even but it may not continue to work.

 

What are the standards that theXHHW-2 / RW90 Conductor meets?

Actually, in most cases, the XHHW-2 / RW90 Conductorexceeds the industry standards which makes it a good choice for your requirements. The various standards that it meets and exceeds are the following –

  • UL Standard 44
  • Federal Specification A-A-59544
  • NEC
  • ICEA S-95-658 / NEMA WC70      
  • OSHA Acceptable
  • c(UL)   Type    RW90

Is the copper XHHW-2 / RW90 good for residential purposes?

The XHHW-2 / RW90 Copper Building Wire Conductor can be used for a lot of applications like raceways, conduits and in industries where powerful and tough wires are needed. However, you can use it for residential purposes also.

 

What the features of the XHHW-2 / RW90 Conductor?

The conductorhas excellent electrical conductivity and very good resistance to moisture.  The conductor also has excellent resistance to compression, pressure and heat.

 

Why is the material of the building wire conductor in Copper?

Copper has been known to be one of the most efficient conductors of electricity and it can carry more current than any other metal used for electricity for a particular diameter of wire.   Moreover, the copper that is used is as per ASTM B8 for stranded wires and ASTM B3 for bare annealed copper wires.

 

What are the advantages of having a building wire conductor in Copper?

When you use copper for building wire, it needs less insulation than aluminum. Also aluminum tends to get aluminum oxide when exposed to air, which hinders the transmission of current. However, copper wires can carry current even if it has copper oxide on it.
