A Guide To Cross-Link Wire

With all the different kind of wire roaming about, it may be tough to choose which is right for your application. Cross-Link Wire is crucial when it comes to severe environments. Have more questions? Read on about this useful wire!

What is Cross-Link Wire?

To put it simply, this wire is a staple when it comes to extreme environments. Commonly found in engine compartments or automotive wiring, it adds protection against corrosive environments and extremely high temperatures. With multiple sizes available (skip down to “different types” for more detail!), it suits a great variety of applications that require more than just an ordinary wire.

How Does Cross-Link Wire Work?

Del City’s wire is chemically cross-linked with polyethylene insulation in order to protect against whatever harsh conditions it may face in order to perform best in extreme environments. The wire is equipped with a high temperature rating to guarantee the bare copper stranding stays isolated. Without this extra insulation, the wire melts or fuses in extreme conditions.

What Are the Different Types of Cross-Link Wire?

The three main types are TXL, GXL, and SXL. These are distinguished mainly by their thickness. The TXL wire has the thinnest insulation, making it the smallest in diameter and weight.  GXL wire provides medium thickness to resist fusing and melting. Lastly, SXL wire had the thickest insulation meaning it can withstand prolong exposure. See the chart below for more specific details on each type..


Your unique application helps you choose which cross-link wire is best for you. For example, if you need added protection but are short on space, the TXL wire would be your best bet. Oppositely, if space is not an option and you need extra protection for long periods of time, the SXL is right for you.
