Product Details：

Product Dimensions：

The technical parameters of the 9L20AXX009XHS are defined by its role in high-voltage surge suppression. It features a Duty Cycle Voltage Rating of 9 kV rms, making it suitable for standard medium-voltage distribution lines. The housing is constructed from a high-quality polymer material, which provides superior hydrophobic properties and resistance to environmental tracking compared to traditional porcelain. As a Heavy Duty class arrester, it is designed to handle high-energy discharge currents typical of severe lightning environments. The unit is typically light in weight, approximately $2 \text{ to } 3 \text{ kg}$ , depending on the specific mounting hardware attached. It complies with major industry standards such as IEEE C62.11 or IEC 60099-4, ensuring reliable performance under transient thermal and electrical stress.

Product Advantages

The primary advantage of the 9L20AXX009XHS is its enhanced durability and safety. The polymer housing is shatter-proof, meaning that in the rare event of a catastrophic failure, it does not throw dangerous shards as a porcelain unit might. Furthermore, the polymer's superior sealing technology prevents moisture ingress, which is the leading cause of arrester failure. Its high energy handling capability ensures that even during intense electrical storms, the arrester can safely divert surges to the ground while protecting expensive downstream equipment like transformers. Additionally, its lightweight design reduces the mechanical stress on crossarms and utility poles, making installation faster and safer for lineworkers.

Important Considerations

Users must observe strict safety protocols when dealing with high-voltage distribution arresters. Installation should only be performed by qualified electrical personnel who are trained in high-voltage safety and the use of personal protective equipment (PPE). Before installation, the unit must be inspected for any signs of physical damage to the polymer sheds or the end caps. It is crucial to ensure that the grounding connection is solid and follows local utility standards, as the arrester’s effectiveness is entirely dependent on its path to ground. Users should also verify that the voltage rating of the arrester matches the system’s line-to-ground voltage requirements to avoid premature failure or lack of protection.

Product Applications

The 9L20AXX009XHS is predominantly used in overhead distribution power lines. It is commonly mounted on utility poles to protect distribution transformers, overhead-to-underground cable transitions (riser poles), and capacitor banks. It is also found in industrial substations where sensitive machinery needs protection from grid-side switching surges. Because of its polymer construction, it is particularly well-suited for applications in harsh environments, such as coastal areas with high salt spray or industrial zones with heavy pollution, where its self-cleaning properties help maintain electrical integrity over its long service life.
