SGT vs SGX Cable

In our This vs. That series, we're comparing (and contrasting) two seemingly similar products. A lot of products seem the same at first glance but can greatly affect the outcome of your next application. In this article, we're comparing SGT and SGX battery cables so you know which is best for your next automotive application!

What is Type SGT Wire?

It is an automotive cable used for starter and battery ground circuits. It features a stranded bare copper conductor and PVC insulation. It has a voltage rating of 50V and a temperature range of -40°C to +105°C. Allied Wire's SGT Wire is manufactured to meet Ford (M1L-56A) and Chrysler (MS-3450) specifications. We also offer this cable in gauge size 6 AWG to 4/0 AWG.

What is Type SGX Wire?

It is a cross-linked cable used in automotive starters and battery grounds. It features a stranded bare copper conductor and XLPE insulation. It has a voltage rating of 50V and a temperature range of -40°C to +125°C. It is also available in sizes 6 AWG to 4/0 AWG. This cable type is often compared to STX wire, another cross-linked battery cable. However, STX wire has a thinner wall.

How do they compare?

The main difference between these two wires is the materials used in their construction, which affects their maximum temperature ratings. Cross-linked polyethylene provides a much higher temperature resistance than PVC. It also provides resistance to abrasion and aging. However, these cables do share the same voltage rating and are both available in red or black. Both of these cables also meet SAE J-1127 standards. When it comes to choosing which wire to use for your next application, it's important to consider the temperatures your wire may encounter.

Can these cables be used in place of Welding Cable?

Since both of these battery cables have a voltage rating of 50V, they may not be used in place of Welding Cable. While welding cable has about the same temperature range and ampacity as these cables, it is much more flexible. However, Welding Cable may be used in place of battery cable per UL 558 and UL 583.
