Description

Product Overview

GCS low-voltage draw-out switchgear adopts standardized modulus design, the main frame adopts 8MF cold-formed profile, and the main frame are mounted with module holes E=20mm. The structure is assembled and partially welded. Each functional unit can operate relatively independently, and the outgoing line function unit can install up to 22 outgoing line circuits. The propulsion mechanism adopts a screw propulsion mechanism, which is stable and reliable. The upper and lower in (out) lines and other options can be used for users. It is suitable for power plants, petroleum, petrochemical, metallurgy, textile, high-rise buildings and other low-voltage distribution systems.

Product Characteristics

  • It improved the heat capacity of the adapter, and greatly reduced the additional temperature rise caused by the temperature rise of the adapter to the connector, cable head and spacer plate.
  • The division between functional units and isolation is clear and reliable, and the fault of one unit does not affect the work of other units, so that the fault is limited to the minimum range.
  • The bus is arranged horizontally, with good stability and convenient installation and maintenance.
  • Up to 22 loops, fully considering the needs of automatic electric door (machine) cluster in large single-unit capacity power plants, petrochemical systems and other industries.
  • The drawer unit has a sufficient number of secondary connectors, which can meet the requirements of computer interface and automatic control loop for the number of contacts.
