VLBCC
These panels, utilized for the optimal operation and control of low-voltage (LV) transformer installations within the utility company’s operational sites, are designed by our specialized team using the E-Plan 5.30 software in compliance with IEC 60617 standards.
Following the mechanical assembly—carried out according to the drawings prepared by our project team—the electrical assembly phase begins. All materials used during the assembly process are of high quality and fully compliant with relevant standards.
VLBCC panels are designed for applications up to 1600 kVA—featuring either sliding or fixed busbar configurations—in accordance with the TEDAŞ MYD 006 specification. During electrical assembly, electrolytic copper busbars are selected based on total power and short-circuit current requirements and are supported at appropriate intervals in compliance with IEC 60439-1 and TS 3367 standards.
VLBCCs perform a number of vital functions in electrical distribution systems:
- For panels where electrical assembly is complete, the devices inside are labeled and the connecting cables are numbered in accordance with the project specifications to facilitate ease of operation and troubleshooting.
- To minimize potential time losses during field connections, our project department prepares tagging, cross-referencing, terminal plans, and bills of materials in addition to the standard functions of the E-Plan design software.
Vertical Load-Break Control Centers (VLBCC) – Frequently Asked Questions
1. What is a VLBCC (Vertical Load-Break Switch Control Center)?
VLBCC is a panel system that enables the safe operation and control of load-break switches in low-voltage transformer installations within the service areas of electricity distribution companies, specifically in a vertical position.
2. Where are VLBCC panels used?
VLBCC panels are used in low-voltage (LV) transformer installations located at the operational sites of electric utility companies for the centralized control and monitoring of the system.
3. Up to what power capacity are VLBCC panels manufactured?
VLBCC panels are designed for use in applications up to 1600 kVA, in accordance with the TEDAŞ MYD 006 specification.
4. What is the difference between the VLBCC with sliding busbars and the one with fixed busbars?
Both types are manufactured in accordance with the TEDAŞ MYD 006 specification; the fundamental difference lies in whether the busbar structure is fixed or sliding (movable). The choice is determined by the facility’s maintenance, expansion, and operational requirements.
5. Which standards apply to VLBCC panels?
The panels are designed using the E-Plan 5.30 software in accordance with the IEC 60617 standard, while electrolytic copper busbars are selected and supported in compliance with the IEC 60439-1 and TS 3367 standards.
6. How is the busbar selection made for VLBCC panels?
Busbars are selected from electrolytic copper suited to the facility’s total power and potential short-circuit currents, and are supported at appropriate intervals in accordance with IEC 60439-1 and TS 3367 standards.
7. What are the advantages of using VLBCC for the business?
- Labeling the devices within the panel and numbering the cables in accordance with the project specifications accelerates fault detection.
- Field installation time is reduced thanks to markings, cross-references, terminal plans, and bills of materials prepared using the E-Plan design software.
- Manufacturing in compliance with TEDAŞ specifications ensures regulatory conformity for distribution companies.
8. How are VLBCC panels manufactured?
Based on the drawings prepared by the project team, the process proceeds first to mechanical assembly and then to electrical assembly; all materials used meet high quality standards.
9. What distinguishes the VLBCC from other panels such as MCCs and PCCs?
VLBCC is specifically designed for load-break switch control in low-voltage transformer substations operated by electricity distribution utilities; MCC is used for motor control, while PCC and MPCC are distinct product families utilized for general power distribution.
10. How can I get a quote for the VLBCC panel?
You can request a quote from the expert GVD team via the contact form by specifying your facility’s power capacity and busbar type preference (sliding/fixed).
