Typical configurations
- The AGE switchgear has great application flexibility for Main Distribution Board, Sub Distribution Board, Motor control Centre. .Several assembly configurations are possible, for incoming ,outgoing and bus-ties.
- The dimensions of the compartment per each breaker have been standardized in order to guarantee to the customers the most compact solutions but also a reasonable space for the cable compartment.
- Also the dimensions of the compartment where the main busbar are located have been standardized.
Switchgear panel frame
-The AGE frame is based on modular 2 mm thick still C sections, pre-drilled at a pitch of 25 mm. Each unit is based on modular elements and consists of:
-All compartments are mechanically segregated from the others.
-The switchgear panel is pre set for easy extensions on both sides.
Circuit-breaker compartment
- The compartment is suitable to accept both air and moulded case circuit-breakers and it is accessible from the front side by means of a locked hinged door. The circuit-breakers can be installed in all the available versions, fixed, plug-in and withdrawable. With all the widrawable circuit-breakers, in order do guarantee the maximum safety level to the operator, the apparatus handling can be carried out with the door closed.
Busbar compartment
- The busbar compartment is located in the middle section of the switchgear. Main busbars can be located at the top, in the centre or at the bottom of the panel depending on the selected design and they distribute the power to the various switchgear panels. In some of the existing configurations main busbars can be directly connected to a circuit-breaker as well. Distribution busbars are located into the single column and positioned vertically to feed panel circuit-breakers. The busbar system can be composed by 1, 2 or 3 busbars per phase, according to requested rated current, short-circuit level and operational ambient conditions in terms of temperature, altitude and humidity. Busbars are normally bare copper made, on request can be suitably treated with tinning, silver-plating and/or sheathing.
Circuit-breaker compartment
- The compartment is suitable to accept both air and moulded case circuit-breakers and it is accessible from the front side by means of a locked hinged door. The circuit-breakers can be installed in all the available versions, fixed, plug-in and withdrawable. With all the widrawable circuit-breakers, in order do guarantee the maximum safety level to the operator, the apparatus handling can be carried out with the door closed.
Cable compartment
-The cable compartment is located in the rear side of the panel and it is accessible by means of a locked hinged door or a removable bolted covers. Its purpose is to contain:
- power terminals
- outgoing cables
- current reducers
- auxiliary terminal blocks (if any).
Cable compartment
-The switchgear is provided with a continuous electrolytic copper earthing busbar, with a cross-section suitable for the proper switchgear shortcircuit rating and pre-set on both sides for connection to the earthing network. Are connected to the earthing busbar:
- all the metallic structures of the individual units
- all not live metallic parts of the circuit-breakers;
- all CTs and VTs secondary earthing connections.
Easy Installation
-Installation and testing duration are considerably reduced as the panel is tested and adjusted in the factory and then delivered as a complete unit.
