While LSZH (Low Smoke Zero Halogen) cables offer several advantages in terms of fire safety and reduced environmental impact compared to other cable types, they do have a few disadvantages:
1.Cost: LSZH cables can be more expensive compared to other cable types, such as PVC (Polyvinyl Chloride) cables. The specialized materials and manufacturing processes required to produce LSZH cables contribute to their higher cost. This cost difference can be a factor to consider, especially in large-scale installations.
2.Limited Flexibility: LSZH cables tend to be less flexible than PVC cables. The LSZH jacket material is generally stiffer, which can make it more challenging to bend and route the cable around tight corners or in applications that require frequent cable movement. This limited flexibility can sometimes pose installation challenges, particularly in environments where cable routing requires more maneuverability.
3.Reduced Mechanical Strength: LSZH cables may have lower mechanical strength compared to PVC cables. The LSZH jacket material is typically softer and less robust, which may make the LSZH cable more susceptible to damage from abrasion, impact, or crushing. This reduced mechanical strength can be a consideration in applications where the cable may be subjected to harsh physical conditions, such as outdoor installations.
4.Temperature Limitations: LSZH cables may have lower temperature ratings compared to PVC cables. While LSZH cables are typically designed to withstand a wide range of operating temperatures, they may have lower resistance to extreme heat compared to PVC cables. This temperature limitation can be a factor to consider in applications where the cable may be exposed to high temperatures, such as in industrial environments or near heat sources.
