What is crucial for insulator fittings?
Interface integrity and strength. Shank dimensions, thread profiles, and crimping processes are controlled to secure long-term performance. We verify with mechanical load tests and corrosion protection audits.
How to choose?
Match mechanical class, environment, and insulator type. We’ll propose the right metal and finish, document tests, and ensure interchangeability. Ready to upgrade line reliability? Reach us at Contact Us.
