Pad Mount Switchgear

Product catalog summary

General Features
Pad mount switchgear is designed for distribution automation systems, integrating circuit breakers, load break switches, and direct circuits. It offers flexibility in distribution line systems with options for SF6 gas insulated and solid insulated switchgear, supporting various control choices.

Technical Specifications
The switchgear is available in different configurations with rated maximum voltages of 15kV and 27kV, and a rated continuous current of 630A. It supports closed loop and load breaking currents of 630A, cable charging breaking current of 25A, and transformer magnetizing breaking current of 21/15A. The short circuit breaking capacity is 12.5 kArms, with a peak withstand current of 32.5 kApeak.

Configuration and Ordering
Switchgear configurations include multiple combinations of circuits, such as load break switches and circuit breakers. Options for manual, electrical, and automatic operations are available, with built-in RTU options for remote operation.

Control and Operation
Each circuit has independent operation functions with status indicators for circuit breakers and load break switches. The load break switch features a 3-position operation for enhanced making and disconnecting capacity, and a natural locking structure to prevent mis-operation.

Safety and Additional Features
Safety features include live line indicators, voltage/current sensing bushings, and overpressure rupture discs. The switchgear is equipped with a battery for dead line operation and a manual trip device option.

Remote Communication and Protection
Remote communication is facilitated through RS232 ports with DNP3.0 protocol. Protection features include editable time current curves, overcurrent protection, and underfrequency/load shedding capabilities. Metering functions measure voltage, current, power factor, and load profile data.

Construction
The switchgear is available in SF6 gas type and polymer (solid) type constructions, ensuring durability and reliability in various environments.
