Heightened safety requirements

Production of appliances for systems with heightened safety requirements;

А) Partial discharge level amounts to not more than 5 pC, which is 4 times less than the acceptable value for “a” class insulation. All 100% of products undergo tests with measurement of partial discharge.

B) Polymeric insulation with comparative tracking resistance index CIT 450.

C) High compound homogeneity ensures long service life of the insulation.

D) A three-step metrological quality control system.

E) Mechanical design group М5, frequency range 5–200 Hz, maximum acceleration 30 m/s2, seismic resistance at SSE of 9 points.

F) Extended creeping distance, which makes operation under high air humidity possible (up to 98%).
