1.1.2 Surface treatment

The complete steel construction including all steel profiles, partitions, top covers, doors are protected against corrosion by acid washing, phosphating process followed by priming and final textured powder coating. The standard colour of the framework is RAL 7024 (graphite grey). The front doors and covers are in standard colour RAL 7035 (light grey). Other colours are available on request. Refer to colour system, RAL, Munsell or NCS and the specific colour ID number. The assembled mounting plates/brackets inside the panel are of zinc-galvanized steel.

To prevent the blur on surface during installation onboard, the doors and cover plates are independently protected with transparent plastic membrane, so that they can be properly opened/ closed for handling or inspection under the packaged condition without unpacking.

1.1.3 Cable entry

Entry of external power cables and control cables in switchboards can be from bottom and top as per requirement. For insertion and stripping of the cables sufficient space inside the switchboard is provided. Connection of power cables to the switchgear will be done directly without intermediate terminals. For fastening of power cables inside the switchboard, necessary numbers of perforated angle bars or cable trays will be fitted inside each panel for allowing sufficient fixing strength.
