Difference between LSF and LSHF (LSZH)

For safety and the best electrical wiring, you should use LSF (Low Smoke and Fumes/Zero Halogen) or LSHF (Low Smoke Halogen Free) cables. The good thing about being able to choose cable from Huatong cable, is the fact that Huatong cable already knows the significance of making the right choice for a cable. In this post, we will explore the main differences between LSF and LSHF cables, and what to consider when choosing the best one for your build.

LSF vs LSHF Cables

LSF cables are produced using compounds that generate low smoke and fumes when over-exposed to heat. On the other hand, LSHF cables produce very low quantity of smoke and no noxious gases during burning. The difference, however, is in how they are made and how they behave in a fire.

Deciding between LSF and LSHF cables

If you’re having trouble deciding between LSF and LSHF cables, consider what’s right for your project. LSF cabling may be cheaper and easier to source, but cabling LSHF is safer, which can be very important for some uses. The Huatong cable recommends that you consult a professional to determine which cable is right for your wiring requirements.

Why LSF and LSHF Cables Are Environmentally Friendly

For environmental reasons LSHF cables are preferable because they don’t emit toxic gases if they burn. LSF cables also restrict the escape of smoke and fumes but are not as environmentally friendly as LSHF cables. If your project is ecofriendly, LSHF cables may be the more responsible choice.

Flame Retardancy Differences

When considering the type of cables for electrical jobs, flame retardancy is an important consideration. LSF cables are made of fire-resistant materials, which will lengthen the time it takes for flames to spread, whereas LSHF models can extinguish themselves and produce very little smoke. One cable could be better than the other depending on fire safety requirements.

Considerations for Selecting Cables

Some of the considerations when selecting between LSF and LSHF cables are fire safety regulations, environmental issues, and associated costs. Huatong cable advises you to carefully check the requirements of your project to determine what type of cable is right for you. And you can partner with a good cable provider to find your high-grade and dependable products for your wiring requirements.

In summary, Solar/PV Cable  are advantageous for specific projects. By understanding the distinctions between the two and considering important factors including environmentally friendly and flame retardancy, you can make an intelligent choice for your electrical wiring works.
