Product name:

GCS type low voltage withdrawable switch cabinet

Product introduction:

GCS type low voltage withdrawable switch cabinet is suitable for power systems with AC 50~60Hz and rated working voltage up to 690V; used for power generation, transmission and distribution, power distribution, power conversion and control of power consumption equipment. It is widely used in power systems, petroleum and petrochemical, industrial and mining enterprises, public utilities, municipal engineering, commercial buildings and other industries.

Product features:

1. GCS type low voltage withdrawable switch cabinet is a switch cabinet designed and developed by the two joint design groups to promote the technological progress of my country's low voltage industry and accelerate the replacement of low voltage complete switchgear. It conforms to national conditions, has high technical performance indicators, and can adapt to market development needs. After summarizing many years of production experience, our company has made improvements in component selection and cabinet structure. The cabinet frame structure is highly flexible, and standard components of various specifications can be installed in the cabinet. Since the entire system adopts a modular design, it can meet the installation requirements of various components, can be applied to different working environments, and can achieve the corresponding protection level.

2. Improve the heat capacity of the adapter and significantly reduce the additional temperature rise of the connector, cable head and partition due to the temperature rise of the adapter.

3. The separation between functional units and compartments is clear and reliable, and the failure of one unit will not affect the operation of other units, so that the failure is limited to the minimum range.

4. The number of circuits of a single MCC cabinet is up to 22, which fully considers the needs of large single-unit capacity power plants, petrochemical systems and other industries for automated electric doors (groups).

5. The layout of the distribution circuit is economical.

6. Cabinets with corresponding protection levels can be designed according to different requirements of work and environment.

7. Different types of functional units can be freely installed in one cabinet, such as fixed and withdrawable.

8. Independent mechanical locking mechanism, flexible and convenient operation, no special complex tools required.

9. There are two options for side outlet and rear outlet.

10. The equipment has high continuity and reliability in operation.

11. The door panels, side panels, top cover, bottom plate and frame are electrostatically sprayed. The internal metal parts are made of aluminum-zinc plate material, which has strong corrosion and oxidation resistance and higher mechanical strength than the same steel plate.

12. The top cover of the rear-outlet switch cabinet is openable, which is convenient for the installation of the main busbar on site.

Technical standards:

The design of the switch cabinet complies with standards such as IEC 61439 and GB 7251, and has passed the CQC voluntary certification.

Working and environmental conditions:

1. GCS type low-voltage withdrawable switch cabinet is suitable for indoor installation, and the protection level of the switch cabinet under other working conditions can reach IP54.

2. Ambient temperature: maximum temperature +40℃, minimum temperature -5℃.

3. The maximum average temperature of 24 hours is +35℃.

4. When the equipment is used in an environment and temperature higher than the above, it should be operated at a reduced capacity.

5. The working conditions of measuring instruments, metering instruments and protective relays shall comply with the manufacturer's regulations.

6. Environmental conditions: clean air. During normal operation, the relative humidity of the surrounding environment shall not exceed 50% at 40°C.

7. The conditions of the installation location in the switch cabinet shall meet the requirements of the relevant standards. In places where condensation may occur, ventilation or heating measures will be used in the switch cabinet to prevent condensation.

8. Altitude: not more than 2000 meters. If the switch cabinet is installed at an altitude of more than 2000 meters, the equipment shall be operated at a reduced capacity accordingly.
