Special service conditions
Each special service condition should be proposed in advance and confirmed by the manufacturer and user.
The dielectric strength of the air will be reduced in when altitude is over 1000m at site.
If the ambient temperature is over the maximum degree, the capacity of the using current must be lower than the designed current's for both main bus bar and branching bus bar. The installation of aerator is propitious to reduce heat.
Type designation of GCS switchgear
Structural feature of GCS switchgear
The main frame of product is made of 8MF sectional steel, has two structure types: assembling type and part welding type. The main frame is set with the mounting holes of module E=20mm. Each functional compartment of product is isolated strictly. Its compartment has divided into functional unit compartment, bus-bar compartment and cable compartment. The function of each unit is impendent.
The module of drawer layer height is 160mm. There are five sizes series: 1/2 unit, 1 unit, 3/2 unit, 2 unit and 3 unit. The rated current of unit circuit is 630A and below. The drawer is changed in height and the width, and the depth is constant. The drawers with the same functional unit are interchangeable. Each motor control center (MCC) cubicle is only mounted 11drawers of 1 unit or 22 drawers of 1/2 unit. Hereinto, the drawer of 1 unit above is provided with the multi-function rear plate. The number of drawer inlet / outlet plug can be provided according to the current capacity. The drawer unit is mounted with the mechanical interlocking mechanism.
Both feed cubicle and motor control cubicle are provided with the cable compartments. The connection between functional unit compartment and cable compartment is done with the adapter or copper bus-bar, to improve the reliability use of cable and take convenience has two widths: 240mm and 400mm that are optional decided by the cable quantity, section as well as users requirements on convenient installation and maintenance.
