The Wide Applicability Of Our 600 Volt Wire

26th Feb 2020

If you’re an electrician and you’re shopping through our pages, you probably know exactly what you’re looking for and what it’s used for as well. If not, you might be wondering about why we offer so many examples of  600 volt wire and cable, and what they’re typically used for. You will likely notice that there is an overwhelming number of listing for 600 volt wire with seemingly little difference between the options. We’re here to help break down some of the nuanced differences between some of our cables and wires rated to 600 volts.

First, it’s worth noting that one of the main reasons we offer so many copper 600 volt wires and cables is because of the fact that they have so many uses in residential and commercial settings for lighting and other power supplies, but that will become more evident throughout this piece.

600 Volt Copper Cables
Here at EWCS Wire, we offer a broad range of copper cables rated to 600 volts that can be used for a wide range of applications. We offer basic copper building wire rated to 600 volts from 2 to 6 AWG and in a range of colors to keep wires for separate supplies differentiated. We offer black, red, blue, green, white, yellow and orange jacketed cables. Many of them are THHN or THWN rated, meaning that they are either high heat resistant and nylon coated or heat and water-resistant and nylon coated, respectively. Our stranded THHN wire can be used for power and lighting in commercial, industrial and residential settings in conduit. It also exhibits a high degree of abrasion resistance.

We also offer VNTC and XHHW-PVC copper tray cables for a variety of settings. Setting up trays instead of conduits has been gaining ground for laying wires for a number of reasons. Trays allow for a greater release of heat than conduits, are cheaper to install and typically much cheaper to service than conduits. In addition, it’s easy to lay wires down along a tray than to pull them through a conduit. Here at EWCS Wire, we offer 600-volt tray cables in a variety of wire gauges and with as many as 37 conductors. Our VNTC (Vinyl Nylon Tray Cable) is approved for free air, in raceways of for direct burial, although it is also sunlight resistant. Our XHHW (Cross-Linked Polyethylene High Heat and Water Resistant) tray cables are extremely versatile, approved for cable trays and conduits as well as direct burial. They all come with a bare copper ground wire.

We also sell Teck Armored Cables rated to 600 volts in 10, 12 and 14 AWG. Armored cables are typically used in extremely rugged environments where the wires and cables need protection from harsh conditions, chemicals and machinery, and our cables are no different. Our armored cables feature a bare copper ground wire, cross-linked polyethylene (XLP) insulated conductors, an inner PVC jacket and interlocking armor cased in another layer of PVC. They’re just about as tough of a cable as can be bought and typically reserved for the harshest situations.

Aluminum Cables
In addition to these copper wires and cables listed, we also sell aluminum triplex, quadruplex and building wire and cable rated to 600 volts. Aluminum cables are sometimes used over copper due to their high conductivity and ductility and low weight. Our aluminum building wire is designed to be used in secondary distribution circuits in ducts. In addition to our aluminum building wire, we also sell triplex and quadruplex wire, many of which are intended to serve as a power supply from a transformer to a service entrance, although some are intended for burial. Many of these cables feature a steel cable in addition to the conductors to enable the cable to withstand high tension.

Other 600 Volt Cables
In addition to these building wires and cables, we also offer 600 volt rated welding and marine cables. These cables are also used to supply power but for more specialized applications, and as a result, they possess traits suiting them to those environments. In both cases, they are developed with a high strand count for the maximum flexibility required in welding applications and in the rolling interior of a vessel. They also offer additional features to make them corrosion and abrasion resistant, though this varies by the line offered - for more information see our pages for marine cables and welding cables.

There is a wide range of uses for 600 volt wire and cable, from residential lighting power supply to tray cable power distribution. We offer many options for lots of different settings right here at EWCS Wire, so be sure to consult an electrical engineer for more information regarding the specific uses and qualities of different types of cables. We’re also proud to report that all of our products are made right here in the U.S.A., that we offer fast shipping and that satisfaction is guaranteed on all of our products.
