Engineering Support For LV Panel Design And Drawings
LV switchgear projects depend on accurate drawings before production. Panel size, feeder arrangement, cable entry, breaker configuration, control wiring and terminal layout should be confirmed clearly before the cabinet is built. Our engineering team reviews your SLD, panel schedule, load list, MCC schedule, room layout and specification, then prepares practical drawings and documents for approval, production, installation and FAT.
Protection Coordination And Short-circuit Rating Review
A cabinet should not only match the required current rating. It also needs proper short-circuit withstand capacity, breaker breaking capacity and reasonable coordination between the incoming breaker, busbar system and outgoing feeders. We review your SLD, transformer capacity, fault level, load schedule and feeder list to confirm whether the selected ACB, MCCB, MCB, busbar and protection devices suit your electrical system.
Each breaking point and busbar rating is checked against your project fault level.
Fault Level Confirmation
We check the available short-circuit current at the LV side from your project data, transformer capacity and system condition before selecting breakers and busbar ratings.
Breaker Breaking Capacity
ACB, MCCB and MCB breaking capacity is selected according to the fault level at each panel position, not only by load current.
Busbar Withstand Rating
Main busbar, neutral busbar and PE busbar are reviewed against rated current, short-time withstand current and peak withstand current.
Upstream And Downstream Review
We review the relationship between incoming breakers, outgoing feeders and downstream panels to reduce unnecessary power interruption from poor protection arrangement.
Motor And Feeder Protection
For MCC and industrial panels, motor feeders, VFD feeders, soft starters and large loads are reviewed by starting method, protection requirement and control logic.
Protection Setting Support
When project data is available, we support discussion on breaker settings, overload, short-circuit, earth fault protection and selective coordination requirements.
Worried Your Breaker Rating Might Not Match The Fault Level?
Send your transformer capacity, fault level and feeder list. We check breaking capacity, busbar withstand and protection coordination against your system, so the panel is safe before it goes into production.
Busbar Design, Temperature Rise And Ventilation
The busbar system is one of the most important parts of an LV switchgear cabinet. For high-current panels, busbar size, joint connection, support spacing, insulation clearance, ventilation and enclosure protection are reviewed together before production. We design the arrangement around your rated current, short-circuit level, panel structure, ambient temperature, IP rating, cable entry and installation space, for stable current distribution, easier maintenance and better heat dissipation.
Main Busbar Arrangement
Designed around your rated current, incoming feeder position, outgoing feeder arrangement and panel layout. Copper or aluminum busbar can be discussed by project requirement, budget and specification.
Short-circuit Withstand Review
Busbar support, phase spacing and connection structure should match your short-time withstand and peak withstand current. Reviewed together with breaker selection and project fault level.
Joint Connection And Inspection
Busbar joints, contact surfaces, bolts and connection points need careful assembly and inspection. Proper tightening, contact area and clear phase identification help reduce overheating risk.
