GPNY40.5-320S 40.5kV Capacity insulator (Sensor)
The 40.5kV Sensor-Embedded Insulator combines primary insulation with condition monitoring capability for high-value MV assets. It is designed for 40.5kV switchgear and distribution systems where real-time or periodic monitoring helps improve reliability, reduce unplanned outages, and support predictive maintenance.
- Overview
- Recommended Products
The 40.5kV Sensor-Embedded Insulator combines primary insulation with condition monitoring capability for high-value MV assets. It is designed for 40.5kV switchgear and distribution systems where real-time or periodic monitoring helps improve reliability, reduce unplanned outages, and support predictive maintenance.
The embedded / integrated sensor module can be configured (depending on model) to monitor temperature rise, electric field, leakage current, partial discharge-related signals, or mechanical stress, providing data to support maintenance decisions. Output and integration can be tailored for local indicators, wired communication, or gateway-based monitoring as required by the project.
Integrated Insulation + Monitoring in One Component
Reduces additional mounting complexity and improves monitoring point consistency.
Selectable Monitoring Targets (Model-Dependent)
Temperature / leakage current / electric-field / PD-related signals / mechanical load (as configured).
Improved Asset Reliability and Maintenance Efficiency
Enables earlier abnormal trend detection and supports condition-based maintenance planning.
Engineering-Friendly Integration
Flexible output/interface options to match protection/automation systems (wired or gateway-based).
High-Voltage Insulation and Mechanical Support
Maintains core insulation/support performance while adding sensing capability.
Customization by Drawing and System Requirements
Mechanical interfaces and sensor placement can be tailored for different switchgear layouts.
