World-Class Switchgear Panel Engineering & Enclosure Systems
VOLTCORE manufactures robust High Tension (HT) and Low Tension (LT) switchgear panels conforming to IEC 62271, IEC 60947, and DIN 41488 standards for industrial plants, infrastructure facilities, and commercial complexes.
Our switchgear panels are sheet steel (12–16 SWG) cladded with modular systems for assembling cubicles intended to house heavy electrical equipment. They are dust and vermin proof, suitable for free-standing or against-the-wall installation, available in single or double-fronted arrangements, and feature an all-round floor-mounting indoor steel enclosure with 99.9% electrolytic TPN & E copper busbars.
We integrate internationally renowned circuit breaker brands such as ABB, Schneider Electric (Merlin Gerin), and SIEMENS inside our panels, or manufacture strictly as per customer requirements and approved Single Line Diagrams (SLD).
Fixed Type & Draw-Out Type Switchgear Panels
VOLTCORE manufactures both fixed-mounted and withdrawable draw-out switchgear panels tailored to plant operational philosophy, safety clearances, and routine maintenance protocols.
Fixed Type Switchgear Panels
VCB / LBS panels suitable for cubicle switchgear installations with rigid bolted base mounting.
- Rigid Panel Base Mounting: Each switchgear panel cubicle is securely anchored to the substation floor or panel foundation frame with high-tensile base bolting.
- Optional Panel Mobility: If requested, fixed-mounting switchgear panels are equipped with heavy-duty castors/wheels to facilitate panel positioning and substation lineup integration.
- Direct Busbar Linkage: Direct rigid copper connections between panel busbars and switching terminals ensure lowest contact resistance and maximum thermal stability inside the panel.
- Secure Panel Terminal Chamber: Main busbar connections inside the panel are secured with high-tensile torque bolts; control wiring and earth terminals are systematically arranged and labelled.
Draw-Out Type Switchgear Panels
Withdrawable breaker panels mounted on precision guide cradles with automatic safety shutters and mechanical interlocks.
- Precision Panel Cradle Assembly: The draw-out breaker truck and cradle glide smoothly into the panel cubicle without requiring site mechanical adjustments.
- Multi-Level Panel Safety Interlocks: Mechanical interlocks prevent racking the panel truck in or out while the circuit breaker is closed, preventing accidental arcing.
- Automatic Panel Safety Shutters: Heavy-gauge metallic shutters automatically drop and shield live primary busbar contacts when the breaker is racked out of the panel.
- Factory-Integrated Panel Components: All panel switching elements, CTs, PTs, and IDMT protection relays are imported from world-class manufacturers (ABB, Schneider, Siemens) and factory wired.
VCB Panel (Vacuum Circuit Breaker Panel)
VOLTCORE Vacuum Circuit Breaker (VCB) Panels offer outstanding operational reliability, rapid arc quenching, and minimal maintenance—ideal for substation incoming panels, out-feeder panels, and high-capacity power transformer protection panels.
Advantages & Engineering Features of VOLTCORE VCB Panels:
- Hermetically Sealed Vacuum Interrupters: Arc quenching occurs inside sealed vacuum bottles within the panel enclosure, isolating high-voltage arcs completely from ambient atmosphere.
- Maintenance-Free Panel Interrupters: The VCB panel requires zero SF6 gas replenishment or oil filtering throughout its operational service life.
- Low Contact Erosion & Extended Life: Premium copper-chromium contacts minimize electrical wear, ensuring thousands of full-load and short-circuit operations inside the panel.
- Instant Dielectric Recovery: Fast dielectric recovery prevents restrikes and destructive high-frequency switching surges within the panel busbar system.
- Auto-Reclosing Panel Duty: Fully rated for rapid auto-reclosing duty cycle (O-0.3s-CO-3min-CO) to protect and restore grid power after overhead feeder faults.
- Compartmentalized Panel Design: Fully arc-segregated busbar chamber, draw-out breaker cell, cable & CT/PT termination chamber, and low-voltage control & metering chamber with automatic safety shutters.
LBS Panel (Load Break Switch Panel)
The VOLTCORE Load Break Switch (LBS) Panel provides an economical, highly dependable HT switching and transformer protection panel for 11kV distribution substations and industrial branch feeders.
LBS Panel Capabilities & Safety Interlocks:
- HRC Fuse Link Protection: The LBS panel integrates high-rupturing capacity (HRC) striker pin fuses providing rapid short-circuit clearance up to 50kA.
- Integral Panel Earth Switch: Mechanical safety interlocks ensure the earth switch cannot be closed while the panel is live, and the main switch cannot close while earthed.
- Three-Pole Trip Mechanism: Operation of any fuse striker pin instantly trips all three poles within the panel, eliminating single-phasing risk on connected transformers.
- Snap-Action Spring Charging Drive: Stored-energy spring charging drive ensures rapid contact make-and-break inside the panel chamber independent of manual operator handle speed.
- Direct Panel Inspection Window: Front panel inspection window allows maintenance engineers to visually verify contact air gaps before opening panel doors.
ACB Panel (Air Circuit Breaker Panel)
Engineered as the primary incoming switchgear panel for distribution transformers and diesel generators, or as an automatic bus-tie coupler panel. Our ACB Panels are available in both fixed and 3-pole / 4-pole draw-out cubicle executions.
ACB Panel Features & Digital Protection:
