GSC Low-Voltage Drawout Switchgear Cabinet | LV Switchgear

Overview

The GSC low voltage drawout switchgear cabinet is a low voltage distribution cabinet with a drawout (withdrawable) design, used for power distribution and control in low voltage systems. Drawout construction means the functional units can be withdrawn from the cabinet for inspection, maintenance or replacement.

Correct handling on site has a direct effect on how the cabinet performs once energised. The guidance below sets out the arrival inspection, temporary storage and installation steps that apply to the GSC cabinet, together with the tolerances that must be met when units are installed individually or in a row.

Key Features

• Drawout construction — a withdrawable low voltage switchgear cabinet for distribution and control.
• Arrival inspection — the packaging should be checked for integrity and any damage on arrival, and problems reported promptly to the relevant contract departments so business records can be made, causes analysed jointly, and the documentation and aftermath handled.
• Correct temporary storage — products not to be installed immediately should be temporarily stored in appropriate places according to the usage conditions and the electrical equipment temporary storage regulations, and kept properly.
• Installation to drawing — installation should be carried out according to the installation diagram.
• Base channel and fixing bolts — the base channel and the bolts used for the bolted fixing method are to be provided by the user.
• Busbar surface preparation — when connecting the main busbars, if the surface is uneven due to transportation or storage, it should be levelled before connection and tightening.
• Alignment tolerances — when the device is installed individually or in a row, the verticality and flatness of the cabinet face and the deviation of the gap between cabinets must comply with the specified table of tolerances.

Technical Specifications

Applications

• Low voltage distribution rooms — indoor distribution and control in buildings and plants.
• Substations — low voltage side distribution where withdrawable units are preferred for maintenance.
• Industrial installations — plant distribution boards where individual functional units need to be inspected or replaced.
• Multi-cabinet line-ups — installations where several cabinets are joined in a row and alignment tolerances must be met.

Installation Conditions

• On arrival, first check the packaging for integrity and any damage. If problems are found, report them promptly to the relevant contract departments to make business records, analyse the causes jointly, and handle the documentation and aftermath.
• For products not to be installed immediately, store them temporarily in appropriate places according to the usage conditions and the electrical equipment temporary storage regulations, and keep them properly.
• Carry out the installation according to the installation diagram.
• Provide the base channel and the bolts used for the bolted fixing method — these are supplied by the user.
• When connecting the main busbars, level any surface that is uneven due to transportation or storage before connection and tightening.
• When the device is installed individually or in a row, the verticality and flatness of the cabinet surface and the deviation of the gap between cabinets must comply with the specified table of tolerances.

How to Select

• The number of cabinets and units required, and whether they will be installed individually or joined in a row.
• The base channel and fixing bolt arrangement available on site, since these are provided by the user.
• The main busbar run and the positions where busbar connections will be made.
• The storage arrangements available for cabinets that cannot be installed immediately after arrival.
• The alignment tolerances that must be met for the cabinet line-up.
