HT Switchgear (LBS & VCB) Supplier in Bangladesh
Short Description
Detailed Description
At Bangladesh Power Innovation Ltd. (BPIL), we bring our distinguished substation expertise to state-of-the-art High Tension (HT) switchgear — the critical control and protection system for power distribution in industries, large commercial complexes and utility substations.
What Is HT Switchgear and Why It's Essential HT switchgear is an assembly of electrical disconnect switches, fuses and circuit breakers used to control, protect and isolate high-voltage equipment — typically operating at 11 kV or above. It's the primary safety and control hub where high-voltage electricity enters your facility from the main grid, ensuring personnel safety, equipment protection, operational continuity and regulatory compliance.
LBS vs VCB: Choosing the Right Solution
Load Break Switch (LBS) — A mechanical switching device for load switching and isolation. BPIL supplies LBS for transformers from 100 kVA up to 500 kVA. Under Bangladesh's current regulations, LBS is mandatory for transformers between 315 kVA and 500 kVA. Cost-effective, simple to operate, reliable isolation.
Vacuum Circuit Breaker (VCB) — A modern circuit breaker using vacuum as the arc-quenching medium — highly efficient and virtually maintenance-free. BPIL typically supplies VCBs for transformers 630 kVA and above, where higher fault-interruption capacity is required. Superior arc quenching, high interrupting capacity, longer lifespan, minimal maintenance.
LBS vs VCB Comparison
| Feature | LBS | VCB |
|---|---|---|
| Interrupting Capacity | Lower (needs fuses) | Very high (self-contained) |
| Operating Speed | Slower | Very fast |
| Maintenance | Regular | Minimal |
| Typical Application | 100–500 kVA | 630 kVA+ (optional from 100 kVA) |
Transformer Protection: Buchholz Relay The Buchholz Relay, installed on oil-filled transformers, detects internal faults and sends a trip signal to the HT switchgear, which instantly isolates the faulty transformer — preventing catastrophic damage and protecting your entire system from outages.
World-Class Components Hyundai, ABB, Chint, Schneider Electric, Siemens and Mitsubishi Electric — ensuring maximum protection, longevity and peace of mind.
Why Choose BPIL Years of experience delivering complex substation projects, strict adherence to Bangladeshi regulations and international safety standards, customized solutions tailored to your voltage and current rating, and comprehensive support from consultation through after-sales service.
