Do you want to learn more about LT XLPE cables, why they are emerging as a favoured product, or how they fit into what would be your real-world use? This blog will provide this essential info. We will cover everything from LT XLPE design, advanced features, to detailed examples of use.

What Are LT XLPE Cables?

Let’s break it down. “LT” stands for “low-tension”, and these are cables designed to work in systems below 1.1 kV. “XLPE” stands for cross-linked polyethylene, which is a specific type of insulation that increases thermal and mechanical performance. LT XLPE cables are power cables that were meant to have a better capability for low-voltage applications. LT XLPE cables have struck a chord in the marketplace for good reason.

Whether it be a new residence, a commercial property, or an industrial facility, these cables meet all the requirements for safety, performance, and longevity. Concerning durability, the structures of LT XLPE cables provide superior performance in adverse conditions, thermal, mechanical and environmental; simply put, they are designed to last longer, perform better in adverse conditions, and withstand thermal, mechanical, and environmental conditions better than traditional PVC-insulated cables.

We can say that LT XLPE cables are power cables designed for low-voltage applications, and they are durable, flexible, and offer excellent electrical performance. They have essentially replaced older PVC-insulated cables, which is a nice way of saying their functional properties are superior in nearly every environment.

LT XLPE vs PVC Cables: What’s the Difference?

When deciding between LT XLPE and PVC cables, it’s important to recognize how they perform and the lengths of their durability. In terms of durability, LT XLPE cable is better than PVC cable, by far, in most respects.

LT XLPE can withstand elevated temperature ratings, up to 90°C during normal operations and even higher ratings under short-circuit conditions, while PVC cable only has a maximum temperature rating of 70°C. LT XLPE is also resistant to more chemicals and moisture, making it moa re viable option in harsher environments.

While considering current-carrying capacity, LT XLPE also has better performance than PVC in this area, while also being one of the more efficient cable designs, while losing surprisingly less energy to heat than PVC. Not only is LT XLPE more flexible than PVC, but LT XLPE can be guaranteed for a longer life span, about 30-40 years, not to mention that they have enhanced flame-retardant capabilities than PVC, which decidedly increases overall safety.

While PVC cable may be more cost-effective upfront, LT XLPE cable can be far more cost-effective over time, because of its lifespan and performance.

Installation and Handling Tips

To ensure the optimal performance of LT XLPE cables, one should make sure that the installation follows the best practices:

Select cables to match the install environment; tempered for outdoor or harsher environments.
Don’t bend or pull too heavily on the cables during installation.
Don’t lay cables in soak conditions or highly chemically active areas, unless rated to do so.
Let the qualified electricians do the splicing and termination to avoid performance issues.
Use the appropriate cable glands, lugs, and accessories to protect the insulation.
