enSingle-end service (SES) assembled chamber
The flagship of the MKS product range are the single-end service (SES) assembled chambers, which have included the largest number of design developments of the MKS engineers. SES designed for reception and distribution of alternating three-phase current electric energy (industrial frequency 50 Hz, voltage 6 (10) kV), have high technical and operational characteristics and a perfect visual appearance.
Design configuration
The single-end service assembled chamber is a welded metal structure of 2 mm thick bent steel sections. All structural elements are powder spraying painted. The chamber houses the main circuits equipment; switches drives, disconnectors, and the of auxiliary circuits equipment — on the facade.
