An Approved Electrical Substation Manufacturer — sl. No. 94, from Ministry of Power, Energy & Mineral Resources.
High Voltage Power Distribution & Substation Control
High Tension (HT) Switchgear Panels (11 kV & Above)
Secure & Reliable High-Voltage Grid Protection Solutions for Industrial Infrastructure
Welcome to Moon Star Power & Technology! Backed by a strong heritage in electrical substation EPC projects across Bangladesh, we manufacture world-class High Tension (HT) Switchgear Panels (11 kV). Operating as the primary defense and control entry point for utility high-voltage grid lines, our HT switchgears ensure personnel safety, continuous fault monitoring, rapid arc clearance, and complete protection for heavy industrial infrastructure.
Key Performance Highlights
High-Voltage Safety
Engineered for 11 kV grid entry points to protect plant transformers and equipment.
LBS & VCB Options
Compliant with Bangladesh government regulations for 100 kVA to 3000 kVA setups.
Rapid Arc Quenching
Vacuum interrupting technology ensures instant short-circuit fault clearance.
Relay Interlock
Seamless tripping integration with Transformer Buchholz & OTI protection relays.
HT Switchgear Configurations: LBS vs. VCB
At Moon Star Power & Technology, we provide both Load Break Switches and Vacuum Circuit Breakers engineered according to project kVA capacity and regulatory guidelines:
Load Break Switch (LBS)
Cost-effective switching and isolation solution designed for transformers ranging from 100 kVA up to 500 kVA.
Govt. Regulation Notice: Mandated in Bangladesh for 315 kVA to 500 kVA transformer installations.
Vacuum Circuit Breaker (VCB)
Advanced vacuum arc quenching breaker for high fault interruption capacity. Standard for 630 kVA up to 3000+ kVA systems, and optional from 100 kVA for maximum automated safety.
Superior lifespan with zero atmospheric gas emission.
Technical Comparison: LBS vs. VCB Panels
| Evaluation Feature | Load Break Switch (LBS) | Vacuum Circuit Breaker (VCB) |
|---|---|---|
| Primary Function | Load switching, Isolation, Fuse protection | High-capacity short circuit & overload interruption |
| Arc Quenching Medium | Air Medium | Sealed Vacuum Interrupter Chamber |
| Interrupting Capacity | Moderate (HRC Fuses used for fault protection) | Extremely High Self-Contained Interruption |
| Maintenance & Lifespan | Periodic contact inspection required | Minimal maintenance with extended operating cycles |
| Recommended Transformer Capacity | 100 kVA to 500 kVA (Govt. Mandated 315-500 kVA) | 630 kVA to 3000+ kVA (Optional from 100 kVA) |
Integrated Transformer Trip Protection
Our HT Switchgear panels feature dedicated trip coils synchronized directly with transformer safety instrumentation (including Buchholz Relays, Pressure Relief Devices, and Oil/Winding Temperature Indicators). Upon detecting internal gas buildup, short-circuit faults, or thermal overheating, the relay instantly sends an electrical trip signal to isolate the HT breaker, preventing costly transformer destruction and grid disruption.
