ZW32-12 Pole-mounted Type
The ZW32-12 product is widely used in the market due to its compact size, reliable and convenient operation, and oil-free/SF6-free design. With numerous advantages, it is extensively applied in overhead distribution lines across various regions, earning widespread recognition from grid users. It has been included in the State Grid's 2021 standardized scheme. Based on the original design, the company has enhanced its protection capabilities and intelligent interfaces to meet the demands for intelligent and customized distribution networks.
Adopts a three-phase tower-type pole-mounted structure, eliminating issues related to condensation and inter-phase insulation breakdown found in shared-box products.
Self-developed deeply integrated pole units, equipped with high-precision, wide-range phase/zero-sequence current and phase/zero-sequence voltage sensors on both sides, integrated with a new capacitor energy harvesting module, meeting the spatial requirements for intelligent and digital applications.
Through improved sealing structure of the enclosure, the switch achieves a protection rating of IP67, with overall partial discharge as low as <20pC, ensuring high product reliability.
