1. How to determine the moisture-resistance level needed for an LSZH sheath compound?
First, it is important to assess the environment in which the cable will be installed. If the cable will be exposed to high levels of moisture or humidity, a higher level of moisture-resistance will be required for the LSZH sheath compound. Additionally, understanding the application and how important it is to maintain functionality of the cable in the presence of moisture can also help determine the level of resistance needed.
2. How to choose the right materials for a moisture-resistant LSZH sheath compound?
Considerations should be given to the additives and fillers used in the compound. The addition of hydrophobic materials such as zinc oxide or silicone can improve the moisture resistance properties of the compound. Additionally, fillers such as talc or calcium carbonate can also help to reduce the absorption of moisture. Choosing a high-quality base resin can also help ensure that the compound has good long-term water resistance performance.
3. How to test the moisture-resistant properties of an LSZH sheath compound?
Various standardized test methods are available to measure the moisture resistance properties of a material. One such test is ASTM D570, which involves conditioning the material in a high-humidity environment and then measuring the weight gain after a specified amount of time. Another test, IEC 60754, measures the amount of acid gas emissions given off by a material when exposed to high temperatures and humidity.
4. How to ensure that the chosen LSZH sheath compound meets the required moisture-resistance level?
After the LSZH sheath compound has been selected, it is important to test it to ensure it meets the desired moisture resistance level. Testing can be done using standardized test methods or by subjecting the material to the expected environmental conditions and monitoring its performance. Additionally, working with a reputable supplier who has experience with LSZH sheath compounds can help ensure that the chosen material meets the required specifications.
