Electrical Distribution Pillars

The electrical distribution pillars is composed of DMC cabinet, fuse switch, copper busbar, busbar system, circuit breaker and other components.

1. Rated working voltage: 380V, 660V.

2. Frequency of use: 50Hz.

3. Rated current: horizontal bus system 1600 ~ 3150A vertical bus system 400 ~ 800A.

4. Rated short-time withstand current: horizontal bus 80KA RMS / 1 second Vertical bus 50KA RMS / 1 second.

Low voltage feeder pillars are installed bottom of the transformers in MV/LV public distribution substations.

At the level of the LV network’s incomers, they assure general on-load breaking or making and the distribution on 4 to 8 feeders protected by fuse disconnect switches.

Additional functions provide new advantages for:

• Better awareness of the requirements for power supply continuity and the safety of property

and persons.

• Preparing the ‘increased intelligence’ of substations; a measurement unit can be installed directly on the panel, for example for monitoring transformer data
