• Rated output: 0–1VA or 0–100mA 
• Accuracy: Ratio difference ≤ ±0.2%, Phase difference ≤ ±15 points 
• Measuring range: 10%In ~ 130%In 
• Working frequency: 50–400Hz 
• Core materials: High magnetic conductivity silicon steel or nanocrystalline 
• Shell material: Weather-resistant, flame-retardant ABS 
• Internal structure: Environment-friendly epoxy resin casting 
• Connection: Terminal type with 2m shielded cable 

These specifications ensure excellent linearity, high sensitivity, and strong anti-electromagnetic interference capability, providing reliable signal transmission for outdoor monitoring and protection systems.

Key Applications

The Outdoor Current Transformer is ideal for:

• Outdoor substation monitoring and protection 
• Power distribution networks 
• Smart grid and intelligent energy management systems 
• Electrical fire monitoring and leakage detection 
• Industrial automation and remote power management 

It is particularly suitable for projects requiring high reliability, precise measurement, and weather-resistant outdoor performance.

Structural and Installation Advantages

• Weatherproof Design: Sealed and UV-resistant housing ensures long-term performance in outdoor conditions. 
• Core Piercing Structure: Allows installation without disconnecting existing lines, reducing downtime. 
• Robust Materials: Flame-retardant epoxy and high-permeability core materials provide durability and precise measurement. 
• Flexible Measurement Range: Supports multiple system configurations, from small feeders to main power lines. 
• Compact and Secure: Mechanically stable shell with screw fixation ensures reliable mounting in outdoor panels. 

Installation & Maintenance

• Open the core-piercing section and thread the conductor through the transformer window. 
• Secure the transformer using the screw fixation points. 
• Connect the secondary output (0–1VA or 0–100mA) to the monitoring or protection device. 

Routine maintenance is minimal, typically limited to inspection of sealing, connections, and mounting integrity.
