At Nassau national cable we supply all kinds of cables and wires and we’d love to be your copper building wire supplier of choice.

The various types of copper building wire found at Nassau national cable include;

 TFFN Copper Building Wire

This type of copper building wire is majorly used for machine tools and lighting fixtures. As its name implies, the conductor is made from copper. As hinted earlier copper is mainly used since it has amazing electrical properties. The conductor is stranded which makes the cable more flexible and able to transmit large amounts of current. It’s also designed in such a way that it carries the desired load without overheating. Whenever there is a conductor it is essential to put an insulator in place for general safety of the users. The insulation used for this type of wire is a PVC material, PVC is the preferred material in this cable because it’s flame retardant. This is very important since most building constructions may be prone to fire incidents.

A nylon jacket is put in place to protect the inner components of the cable from harsh environments that are common in constructions sites for example abrasion, chemicals, gases and oils. When it comes to its industrial ratings and approvals it is UL listed and VW-1 rated.

Cathodic Protection Cable HMWPE 75C 600V Copper Cable

The cathodic protection cable can be installed in direct burial DC feeders mainly for cathodic protection systems in pipelines,tanks, wells, ocean vessels, and metallic structures buried or sub merged in water even though it is not considered as a marine cable. When it comes to its design the conductor is made of copper which is stranded. Covering the conductor is a thermoset compound, polyethylene which serves as the cable’s insulator.

The insulator majorly prevents direct contact with the live wire by users which enhances the consumer’s safety. The cathodic protection cable supplied at Nassau National Cable has an added advantage to other cathodic protection cables you may find in the market. The insulator is very thick and provides resistance from environmental features such as sunlight and abrasion.  Cathodic protection cable is rated 600 volts hence used in medium weight applications but can work properly in a wide range of temperatures since its temperature rating is at 75 degrees Celsius.

Type NM-B Copper Building Wire

When we talk about the Type NM-B cable, it is mostly used in residential wiring as branch circuits for switches, outlets and other loads. This cable can also be used in a wide range of temperature, since its maximum operating temperature is 90 degrees Celsius in dry locations. The cable is relatively used in medium weight applications since its voltage rating is at 600 volts. Its design is quite unique from the previous cables, since it has 2, 3 to 4 copper conductors with a bare ground wire. Covering the conductor is an insulator which is made from polyvinyl chloride (PVC) given its robustness and resistance to harsh environment. The cable also has a jacket which is made from nylon. The cable jacket is color coded to enable our customers to identify the cable size easily.

Copper Conductor Service Entrance Cable

This cable is used in applications whereby power is conveyed from the service drop to the meter base and from the meter base to the distribution panel board. It can also function in a wide range of temperature whereby its maximum operating temperature is at 90 degrees Celsius. It is also most preferred cable for medium weight applications since its voltage rating is at 600 volts. The conductor is made of soft annealed copper. The conductors used are type XHHW-2 which are resistant to sunlight.Covering the inner components of the cable is a PVC jacket and is resistant to sunlight and abrasive forces.

USE-2 RHH RHW-2 Copper Conductor Building Wire

This type of copper building wire is mainly used in conduit. It can also be used for direct burial as an underground service entrance cable and its maximum operating temperature is at 90 degrees Celsius. Furthermore the cable is preferred for applications not exceeding 600 volts. Its conductor is made of soft annealed copper. Covering the conductor is an insulator which is made from black cross-linked polyethylene (XLP). This material has many advantages since it is resistant to abrasion, heat, sunlight and moisture. These amazing features makes this cable durable hence saves you money from constant repair and maintenance.

THHN THWN-2 Copper Conductor Building Wire

It is commonly used in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial applications. This cable can also function in a wide range of temperatures whereby its maximum operating temperature is at 90 degrees Celsius. In addition to this the conductor temperatures are not to exceed 105 degrees Celsius in dry locations when rated AWM and used as appliance wiring material. Like the previous cables its voltage rating is at 600 volts.

Underground Feeder Cable UF-B COPPER 600V

As its name implies these cables are installed underground applications for example,direct burial as a Feeder or Branch Circuit Cable whereby overcurrent protection is provided. With its unique design it can be able to withstand corrosive environments. The cable has an outer jacket which is made from PVC material and can withstand abrasive forces and moisture. With these amazing features you can be rest assured that the underground feeder cable can endure any abuse subjected to it, considering the environment it’s installed in.

Switchboard Wire Strand Tinned Copper Type SIS Cable

The switchboard cable is used in switch boards for control and power circuits. Its maximum operating temperature is at 90 degrees Celsius and the voltage rating is for applications not exceeding 600 volts. The cables conductor is constructed from soft stranded tinned coated copper which conducts electricity within the cable. Covering the conductor is the insulator which is made from cross-linked polyethylene. The cable is available in various colors just to meet our customers desired needs.

Tracer Bare Copper Solid Pe-30 Polyethylene Insulation 30/600v Tracer Wire

This cable has a high strength insulated which is high molecular weight polyethylene (HMWPE) and it is specifically made for direct burial applications. This material used as the insulator is well known for its amazing properties such as its resistance to moisture and abrasion.  Its conductor which is responsible for transmission of electric current within the cable is made from solid copper. It is constructed in both the 30 and 600 volts version.

THHN Solid Bare Copper Pvc Insulation 600v Building Wire

This cable is designed for general purpose use and rewiring of applications that have a voltage rating of 600 volts. It also functions in a wide range of temperature whereby its maximum operating temperature is at 90 degrees Celsius in both wet and dry locations. It has solid bare copper as the conductor. The insulator which covers the conductor is made from color coded PVC and a nylon outer jacket for easy pulling. The cable jacket is also gasoline and oil resistant.

TFN Solid Copper PVC Insulation 600v Building Wire

Type TFN solid copper wire is used as a machine tool, wiring fixture wire, or appliance wiring material. Its maximum operating temperature ranges at 90 degrees Celsius however the conductor temperature is not to exceed 105 degrees Celsius when used as appliance wiring material. As its name suggests this cable is used in applications with a voltage rating of 600 volts.

When it comes to its construction the conductor is made from solid copper since copper is the most preferred metal in this applications. There is an insulator installed right on the top of the conductor. The cable insulator is manufactured from polyvinyl chloride (PVC) because of its robust nature. Nylon (polyamide) is wrapped around the cable as the jacket.
