GALLMAX represents Pfisterer group of companies, manufacturers of a wide range of ceramic and silicone insulators. Together with Pfisterer´s subsidiary, LAPP Insulators, PFISTERER is your experienced global systems partner for insulators and insulator strings up to 1000 kV.

PFISTERER has over 40 years of experience as a pioneer in the field of silicone composite insulators, which includes designing and producing complete insulator strings. For more complicated projects, Pfisterer offer end-to-end solutions from a single source based on an extensive advisory and planning service, and simulations and tests in our own labs.

The polymeric insulators we represent are manufactured under strict quality control and comply with ISO 9001 and ISO 14000 standards, with advanced technology production processes, designed to meet the needs of customers under International IEC and ANSI Standards.

Different dimensions (distances of arc and leakage), mechanical loads, and the types of terminal couplings available gives our clients reliable and guaranteed solutions in the implementation of Power Transmission Systems of up to 1100 kV.
