Selection & Deployment
Selection Recommendations
⚡ Match Voltage Rating Precisely
Always select insulated tools and gloves rated for the actual working voltage. For 10kV substations, use Class 3 (26.5kV) gloves.
✅ Prioritize International Certification
For export projects, select products with IEC 60900 + CE dual certification.
⚠️ Annual Dielectric Testing Required
Insulated gloves and tools must undergo annual dielectric testing. Expired items must be removed from service immediately.
🚫 Never Mix Tool Categories
Never use standard tools in high-voltage environments. Even brief contact can cause fatal arc flash events.
