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.
✅ Rated for 35kV Medium Voltage Applications
Reliable insulation and creepage distance suitable for use in indoor or sheltered outdoor systems.
✅ High Mechanical Strength
Designed to withstand vertical and lateral loads during equipment operation or seismic activity.
✅ Compact and Lightweight Design
Easier to install, especially in compact ring main units (RMUs), gas-insulated switchgear (GIS), or modular substations.
✅ Excellent Surface Finish and Tracking Resistance
Minimizes the risk of surface discharge and partial discharge during long-term operation.
✅ Customization Available
Support for specific mounting holes, interface dimensions, and creepage length based on client requirements or standards (IEC/GB).
