In medium-voltage switchgear and substations, the 35kV insulator is a key component ensuring the mechanical support and electrical insulation of energized parts. Among them, the ZJ-35kV epoxy resin post insulator series has become a widely accepted choice due to its balance of performance, reliability, and adaptability across various installation environments.
The ZJ-35kV insulator is manufactured using APG (Automatic Pressure Gelation) epoxy casting technology, which enables high precision, tight dimensional control, and internal void-free structure. Compared to traditional porcelain post insulators, epoxy resin types like this offer better performance in moisture-prone or polluted environments.
