Main Distribution Panel

Primary electrical switchboard engineered to receive bulk power from utility transformers or generators and distribute it safely to downstream sub-distribution boards and heavy industrial loads. Rated up to 6300A, 690V AC, with short-circuit withstand ratings up to 100kA/1s. Designed for continuous industrial operations, commercial infrastructure, and utility substations requiring strict fault tolerance and regulatory compliance. 

High Fault Withstand Capability: Structural frame and main busbar support systems engineered to handle electrodynamic forces up to 100kA short-circuit current without structural or mechanical deformation.

Modular Internal Separation: Compartmentalized layouts up to Form 4b restrict fault arcs to single zones and allow safe live-front maintenance on functional units without total system shutdowns.

Optimized Thermal Performance: Ventilation configurations and silver-plated busbar joint interfaces maintain operating temperature rises below 65K at full continuous load.

Integrated Metering & Protection: Dedicated instrument compartments designed to house incoming Air Circuit Breakers (ACBs), multi-function power meters, and programmable protection relays.

Heavy Industrial Plants: Central power distribution for metal processing lines, chemical manufacturing facilities, and automated assembly plants.

Commercial Real Estate: Main power aggregation for high-rise office buildings, shopping complexes, and municipal convention centers.

Critical Infrastructure: Core switchboards for data centers, municipal water treatment facilities, and airport terminal power grids.

Renewable Energy Integration: Aggregating multiple utility-scale solar inverter or wind turbine generator feeds before grid synchronization.

Single-Line Diagram (SLD) Matching: Layouts custom-engineered to match provided electrical schematics, top/bottom cable entry requirements, and spatial footprint limitations.

Switchgear Component Integration: Internal mounting provisions configured to house specific third-party components (Schneider, ABB, Siemens, Eaton) or client-specified brands.

Enclosure Dimensions & Finish: Modular bay widths and depths adapted to switchroom constraints; custom RAL color specifications and stainless steel (SUS304/SUS316) options for corrosive environments.

CNC Sheet Metal Fabrication: Amada CNC laser cutting and turret punch systems maintain structural assembly tolerances within +/- 0.2 mm.

Busbar Processing: Automated CNC copper bending and punching centers ensure exact hole alignment and low-resistance connection joints.

Torque Verification & Joint Protection: All copper-to-copper bolted joints tightened via calibrated torque wrenches using disc spring washers; contact surfaces coated with anti-oxidation paste.

Factory Routine Testing (Per IEC 61439-2):

Dielectric properties verification (2.5kV AC withstand test for 1 minute).

Protective circuit continuity check (earth resistance < 0.1 ohm).

Mechanical operation test of breaker interlocking mechanisms.

Standards Compliance: Type-tested in accordance with IEC 61439-1 and IEC 61439-2 standards.

Quality System: ISO 9001:2015 certified manufacturing facility.

Supplied Technical Documentation:

lGeneral Arrangement (GA) layout drawings and 3D step files.
