Cost-Effective GCS & KYN28 Switchgear for Old Factory Renovation
Project Overview
A crystallizer manufacturing plant undertook an old factory renovation. The project required a reliable power distribution upgrade under strict cost-performance constraints.
The electrical system needed to support both high-voltage and low-voltage loads. The selected configuration included GCS low-voltage switchgear, KYN28-12 high-voltage switchgear, and conventional distribution boxes.
Low-voltage components used the Chint brand to balance quality and price. The voltage levels were 10 kV on the high-voltage side and 380 V on the low-voltage side.
Project Background
The plant operated with aging electrical infrastructure. An upgrade was necessary to support continued production.
Budget control was a primary concern. The client required a solution that delivered solid performance without premium pricing.
The renovation had to integrate new switchgear into the existing facility layout. Continuity of power supply during the transition period was also important.
Limited detailed technical documentation from the old system added complexity to the planning stage.
Customer Requirement
The client specified a high cost-performance ratio as the top priority.
The system must handle 10 kV high-voltage distribution and 380 V low-voltage distribution.
Low-voltage switchgear had to use Chint brand components.
The overall solution needed to be practical for an old plant environment and support long-term stable operation.

MEYGO Solution
The solution centered on a combined high- and low-voltage distribution package tailored to the renovation needs.
KYN28-12 metal-clad switchgear formed the 10 kV side. GCS withdrawable low-voltage switchgear handled the 380 V side. Conventional distribution boxes completed the final distribution points.
Chint components were selected for the low-voltage section to meet the cost target while maintaining adequate performance.
The design focused on modularity and ease of integration into the existing plant structure.
Equipment Supplied
- KYN28-12 high-voltage switchgear for the 10 kV system
- GCS low-voltage switchgear for the 380 V system
- Conventional distribution boxes for local power distribution
Low-voltage functional units used Chint brand devices.
Technical Considerations
The KYN28-12 panels provide metal-clad construction. This design separates compartments and supports safer operation and maintenance.
Key safety features of the KYN28-12 include mechanical and electrical interlocking systems. These interlocks prevent incorrect operations such as closing a circuit breaker while the earthing switch is closed or withdrawing a truck under load.
The five-prevention interlocking system reduces the risk of operational errors. Arc-resistant design elements further protect personnel and equipment in fault conditions.
On the low-voltage side, the GCS system uses a withdrawable drawer structure. This allows individual functional units to be removed and replaced with minimal disruption to the rest of the switchboard.


GCS System Maintenance Strategy
A structured maintenance approach helps keep the GCS switchgear reliable over time.
Routine visual inspections should check for signs of overheating, loose connections, or dust accumulation on the drawer units and busbars.
Contact surfaces and secondary connectors require periodic cleaning and verification of tightness.
Functional tests of the withdrawable mechanisms ensure smooth insertion and withdrawal. Interlock operation should be verified during scheduled outages.
Thermal imaging can identify abnormal temperature rises before they develop into faults.
Spare drawer units and common components should be kept on site to reduce downtime during repairs.
Following this maintenance strategy supports long-term stability of the low-voltage distribution system.
Implementation / Production
- The equipment was manufactured according to the agreed configuration.
- Modular design of both the KYN28-12 and GCS panels simplified transportation and on-site handling.
- Installation coordinated with the plant’s renovation schedule to limit production impact.
Testing & Quality Control
- Standard factory testing procedures were applied to the switchgear.
- These included dielectric tests, mechanical operation checks, and verification of interlocking functions.
- On-site commissioning confirmed correct integration with the existing plant systems.
Delivery / Installation
- The complete set of switchgear and distribution boxes was delivered to the site.
- Installation followed the plant layout requirements. Connection work was sequenced to maintain essential power supply where possible.
Project Results
- The renovated distribution system met the required voltage levels and operational needs.
- The combination of KYN28-12 and GCS panels with Chint low-voltage components achieved the targeted cost-performance balance.
- The plant gained a more reliable and maintainable power distribution foundation suitable for continued crystallizer production.
Why This Solution Worked
The solution matched the client’s primary demand for high cost-performance.
KYN28-12 delivered proven safety features for the 10 kV side.
GCS provided flexible and maintainable low-voltage distribution.
Use of Chint components kept the overall investment within budget while meeting functional requirements.
Conclusion / Summary
This renovation project demonstrates a practical approach to upgrading an old industrial plant’s power distribution. The combination of KYN28-12, GCS switchgear, and conventional distribution boxes delivered a balanced solution focused on cost, safety, and maintainability.
