A Legacy of Excellence
From a state-owned pioneer in 1958 to a Fortune 500 subsidiary, and now Vuulcan's global manufacturing base. Our journey is defined by one standard: Reliability.
State-Owned Foundation
Established as the Zibo Electric Porcelain Factory, directly under the Ministry of Water Resources. We were born with a national mission to electrify the country.
Technological Breakthrough
We successfully manufactured China's first 220kV high-voltage porcelain bushing, filling a critical national gap in power infrastructure technology.
Global Standards (Morgan UK)
Joint venture with Morgan Crucible (UK). This era introduced European manufacturing protocols and the DNV ISO9001 quality system which we still uphold today.
Fortune 500 DNA (Tyco USA)
Acquired by Tyco Electronics. Under world-class American management, our facility became a key node in the global insulator supply chain for over a decade.
Strategic Transition (Domasters)
Tyco Electronics transferred ownership, and the entity was renamed Zibo Domasters Insulators. We retained the full production lines, QC systems, and technical team from the Tyco era, ensuring seamless continuity of quality.
Railway Certified (CRCC)
Achieved CRCC Certification, qualifying us to supply China's High-Speed Rail network. This proves our products withstand extreme vibration and mechanical fatigue.
The Vuulcan Alliance
Vuulcan integrates this historic manufacturing base, combining 60 years of production heritage with modern digital service. Direct access, legacy quality.
The Human Touch Behind High Voltage
Machines provide consistency, but our craftsmen provide soul. Many technicians have been here since the Tyco era, applying decades of experience to every insulator.
