XHHW abbreviates some of the characteristics of this kind of cable. The XHHW – 2 Copper Wire has a cross-linked insulation that is resistant to high temperatures. The cross-linked polyethylene insulation jackets the cable and makes it resistant to moisture. With the insulation in place, the conductors are protected from abrasions. In addition to that, the jacket shelters the cable from the corrosive effect of exposure to high temperatures and moist environments. During installation, the jacket is an advantageous feature offering a lower friction coefficient thus enabling ease pulling of the cable through conduits. These quality cables plus many more are sold at Nassau electrical. The cables are tested and proved by the International standards.

Construction
The XHHW – 2 Copper Wire satisfies the UL standard 44 which puts a requirement that the insulation used be thermoset insulation. The purpose of thermosetting is to increase the material flexibility without compromising its toughness and strength. After the process of application of heat and later cooling, the materials especially with rubber-like properties harden and can thus be applied as efficient insulation against chemical corrosion, scratching and high levels of heat.

The cable design allows for two options. One is to have the cable in the form of a solid copper wire. The other option has the wire concentrically stranded. The concentrically stranded model of the cable is more advantageous in terms of flexibility than the solid copper design because stranding the cable makes it more flexible. This increased flexibility makes the cable suitable for a heavy job. The solid copper cable on the other hand beats the stranded model when cost and durability are considered. It is more economical and withstands the effects of corrosion for a longer period because there is minimal surface area exposed to the corroding elements.

The advantage of using copper over other materials is majorly centered about its conductivity. Copper Building Wires an excellent conductor of electricity and thus makes really good cables for electrical conductivity purposes. Another feature of copper that makes it preferable for such cables is its stability and durability. Copper is proven to remain stable even over long periods of continuous operation and use thus providing a favorable material for the construction of the XHHW – 2 cable.

Applications
Brach circuit wiring -This area of application requires a cable with super high flame resistance to avoid regular replacements since branch circuits are done to be used for a long time. Since the XHHW – 2 Copper Wire can be used in moisture free environments and at very high temperatures to approximately 100 degrees Celsius, it is proven to be appropriate for this application. Branch circuits basically consist of wires emanating from the panel supplying electrical power to electrical loads in the house in the form of household appliances.

Feeders - Feeders are the wires that channel power to the electrical panel through the main circuit breaker. From the electrical panel, electrical energy is distributed throughout the rest of the building and to power electrical appliances.

Metal conduit - The XHHW – 2 Copper cable is also applied in Intermediate, rigid, flexible and polyvinyl chloride metal conduits. These are all types of circular raceways whose purpose is to hold wires or cables. Intermediate metal conduit has less thickness on the walls as compared to the rigid conduit and thus the rigid conduit has less room in the interior for passage of cables. Flexible metal conduit is alsoreferred to as Greenfield and is commonly applied between a rigid conduit and a moving or shaking equipment. The polyvinyl chloride conduit on the other hand is lightweight and easily cut but strong nevertheless.

Types of XHHW – 2 Copper Cable
There are several types of XHHW – 2 Copper Wires differentiated by majorly their sizes and expressed in terms of gauges. Here are a few examples;

1. 12 Gauge XHHW – 2 Copper Wire 
This cable has the thickness of the phase conductor insulation at 30 mls and a size of 12 AWG. It is quite lightweight with a weight calculated for every 1000 feet to be averagely 26 pounds.

2. 4 Gauge XHHW Copper Wire
The 4 gauge cable has a thicker phase conductor insulation measured at 45 mls while its weight for every 1000 feet is approximately 6 times more than that of the 12 gauge cable type.
