Every ANBO insulator passes a closed-loop quality system — incoming inspection, in-process control and final type testing — verified by CNAS-accredited laboratories and IEC-compliant procedures.
Honors & Certifications
Originals of our credit ratings, business license, green and smart-manufacturing certifications.
Testing Capabilities
Every batch clears dielectric, mechanical, thermal-mechanical and puncture testing before release — fully recorded and traceable.
Raw materials, cement and metal fittings verified against spec before entering production.
In-line checks on melting, forming, toughening and assembly keep every stage within tolerance.
Routine lot tests plus periodic type tests to IEC 62217 before each batch ships.
Power-frequency and impulse withstand voltage verification.
Tensile failure and routine mechanical-load checks.
Cycles across temperature and load to prove long-term reliability.
Toughened-glass puncture performance for self-shattering fault behaviour.
Proprietary Patents
Utility patents on glass-insulator mounting and self-cleaning designs.
Management System Certification
A full suite of management-system certifications covering quality, environment, occupational health, energy and green supply chain.
