What is copper XHHW?

This copper building wire is intended to be used for general purpose applications in conduit, underground in conduit, or in any other recognized raceways for services, feeders, and branch-circuit wiring. …

What type of wire is XHHW?

XHHW Wire Overview XHHW is an alphabetism or initialism which stands for “XLPE (cross-linked polyethylene) High Heat-resistant Water-resistant.” XHHW is a designation for a specific insulation material, temperature rating, and condition of use (suitable for wet locations) for electrical wire and cable.

What is the most common type of copper cable?

Twisted pair wire is the simplest, cheapest and most common cable. Usually as a twist- ed pair 4-wire cable. It is a standard copper wire in a protective plastic sheath, with or without a protective metal screen.

What is stranded copper cable?

In a stranded cable, each of the eight copper conductors are made up of multiple “strands” of small gauge wires that are concentrically wound together in a helix, much like a rope. The most significant difference between stranded and solid cable is performance.

Is wire pure copper?

Generally it is pure copper. There’re some copper alloys used, for example to increase the physical strength of cables, but these are rare. Pure copper is best for conductivity, especially in electrical power wiring.

Is copper an insulated wire?

The wire which is made of copper, and it can insulate electric current is said to be insulated copper wire. Copper wire used in an electromagnet is insulated with a coating of non-conductive insulation like plastic or enamel which is to prevent from the charging of wires.

What is the difference between XHHW and Thhn?

Dual Rated 600V/1kV. Uses XLPE (cross-linked) Insulation Instead of PVC. Substantially Higher (better) Insulation Resistance….HOW TO KNOW THE DIFFERENCE.

THHN/THWN-2:	XHHW-2:
W = Water Resistant	W = Water Resistant
N = Nylon Jacket	(Not Required)
-2 = Temperature Rated 90°C Wet/Dry	-2 = Temperature Rated 90°C Wet/Dry

Is XHHW oil resistant?

Application. For use in harsh environments for general wiring applications for lighting and power in conduits, ducts, cable tray when CT rated, or other approved raceways with maximum conductor temperature of 90°C in wet or dry locations. XHHW wire is also chemical, gasoline and oil resistant.

Where can XHHW wire be used?

XHHW wire is generally used in residential, commercial and industrial buildings and installations for the purpose of power distribution. The cable is manufactured in both copper and aluminum conductors and typically ran in conduit or other approved raceways for services, feeder and circuit wiring.

How can you tell if something is copper wire?

“Just like real silver, copper is only very slightly magnetic,” Martin says. “You can conduct the same magnet test by placing a magnet on the surface of the item. If the magnet sticks, you can make sure that the item isn’t copper.” Small magnets are also easy for you to bring to the flea market or antique shop.

What is XHHW-2 wire?

XHHW-2 wire is the next generation XHHW wire. While its main use is for residential, commercial and industrial buildings, it is also used in raceways, feeder and circuit wiring. Conductors: Copper or aluminum Wire: Solid or stranded cable – stranded wire is used to maintain flexibility

What does XHHW stand for?

No38 XHHW is an alphabetism or initialism which stands for “XLPE (cross-linked polyethylene) High Heat-resistant Water-resistant.” XHHW is a designation for a specific insulation material, temperature rating, and condition of use (suitable for wet locations) for electrical wire and cable.

What is XHHW insulation used for?

This type of insulation is used for both copper and aluminum conductors which are either solid or stranded, depending on size. According to Underwriters Laboratories (UL) Standard 44, XHHW insulation is suitable for use in dry locations up to 90° C (194° F), or wet locations up to 75° C (167° F).

What is the temperature rating of XHHW-2?

XHHW-2 is approved for use up to 600V and is UL Listed for 90° C (194° F), in both dry and wet locations. The previous generation of XHHW had a lower temperature rating, approved up to 75° C in wet environments, making the next generation XHHW-2 wire a more useful and an ‘all environment’-type product.
