The cable room is mainly used for the connection of cables, so that the single-core or three-core cables can be connected with the simplest unshielded cable heads, and at the same time, the ample space can also accommodate components such as arresters, current transformers, and lower grounding switches. The cabinet door is designed as standard with viewing windows and safety interlocks, and the cable compartment floor is equipped with a sealing cover and a cable clamp of appropriate size with brackets. The front door frame of the cable room floor can be removed to facilitate cable installation.
The interlocking low-pressure chamber also functions as a control screen. The low-voltage chamber is equipped with a spring-operated mechanism and a mechanical interlocking device with a position indicator, and can also be equipped with auxiliary contacts, trip coils, emergency tripping mechanisms, capacitive live display devices, key locks and electric operating devices, while the low-voltage chamber space can also be used for the installation of control loops, recording instruments and protective relays, and the 750mm wide cabinet is equipped with two identical low-voltage chambers, which can be equipped with more accessories.
