Challenge
In Kuwait, where environmental conditions closely mirror those of the arid Southwestern United States, managing airborne pollution and dust accumulation on high-voltage equipment is a major operational concern for electrical utilities. With prolonged dry seasons, high temperatures, and frequent sand and dust storms, the potential for pollution buildup on insulators is significant. This accumulation can lead to surface tracking, flashovers, and long-term degradation of insulator performance if not properly addressed.
Solution – Advanced Desert Shed Profile
To mitigate these risks, many LAPP customers in Kuwait have adopted Porcelain Long Rods, with an open shed profile, also known as ‘Desert Shed’. This specific design is particularly well-suited to dry, dusty climates. The open shed geometry allows for enhanced airflow and reduces the risk of dust settling uniformly along the insulator’s surface. Unlike traditional insulator designs that may trap particulates in narrow gaps, the open shed structure minimizes stagnation zones where debris might collect and cause localized stress points.
One of the most advantageous features of this design is its self-cleaning capability. The combination of smooth porcelain surfaces and an aerodynamic shed arrangement means that natural wind movement can effectively dislodge and carry away accumulated dust and sand. Over time, this helps maintain the insulator’s dielectric properties without the need for frequent manual cleaning or washing, which can be both labor-intensive and resource-demanding in desert environments.
Outcome
By utilizing Porcelain Long Rods with open shed profiles, utilities in Kuwait are not only addressing the challenges posed by dust pollution but are also investing in a sustainable solution that aligns with the harsh environmental demands of the region.
