Περιγραφή

Summary

FLRN36 indoor AC high-voltage load break switch-fuse combination (combination in short)is a comprehensive and new combination app aratus produced on the bases of the mature experience in domestic and abroad. It is a complement apparatus of HXGN15-12/24 AC metal-enclosed ring main unit and it meet requirement of users in different power system. It has the advantages such as simple structure, easy maintenance, strong arc-extinction capability, high gap insulating level and high reliability. It accords with IEC62271-105, GB16926 & GB/T 11022 standards.
