Company: German Grid Modernization GmbH
Country: Germany
Challenge: The company was renovating a 110kV aging transmission line built in the 1980s. The key pain points were: ① Existing porcelain insulators were heavy and difficult to replace; ② Traditional tools could not fit the special tower hardware; ③ The project required compliance with EU REACH environmental standards.
Solution: We provided an integrated customization solution: ① Customized lightweight composite insulators (12kg/unit) with mechanical interfaces matching the old porcelain insulators (complying with DIN EN 50120); ② Developed special-shaped insulated tension tools and quick-connect joints to fit the unique tower hardware; ③ Used REACH-compliant silicone rubber and non-toxic insulation materials.
Result: The renovation project was completed 40% faster than planned, with no modifications to the original tower structure. The new insulators reduced hoisting labor costs by 50%, and the tools’ compatibility rate reached 100%. The project passed EU environmental audits and became a benchmark for old line renovation in Germany.
