VCP-W metal-clad switchgear with type VCP-W vacuum breakers provides centralized control and protection of medium voltage power equipment and circuits in industrial, commercial, and utility installations involving generators, motors, feeder circuits, and transmission and distribution lines. VCP-W switchgear is available in maximum voltage ratings from 4.76 kV through 38 kV, and interrupting ratings as shown below. VCP-W offers a total design concept of cell, breaker, and auxiliary equipment, which can be assembled in various combinations to satisfy user application requirements. Two-high breaker arrangements are standard up to 15 kV. One-high arrangements can be furnished when required.
Maintenance requirements are minimized by the use of enclosed long-life vacuum interrupters, and the component arrangements and drawers allow easy access. VCP-W’s light weight simplifies handling and relocation of the breakers.
VCP-W meets or exceeds all applicable ANSI, NEMA, and IEEE design standard. UL and CSA listed switchgear is also available.
Features, Benefits and Functions
Endurance
High power laboratory tests prove VCP-W breakers are capable of 50 to 200 full fault current interruptions.
Space Savings
Up to 50% floor space reduction over previous designs.
Vacuum Interrupter, Current Transfer Conductor
The stiff-flexible design eliminates sliding/rolling contacts in the main conductor which provides excellent electrical and thermal transfer and long vacuum interrupter life.
Grounded Steel Safety Shutters
Prevents accidental contact with live primary voltage connections when breaker is withdrawn.
Breaker Rails
On 5 – 27 kV units the breaker can be withdrawn on rails for inspection and maintenance without the need for a separate lifting device.
Roll-on-the-Floor
38 kV breaker is designed to roll directly on the floor.
Reduced Breaker Weight
525 Ibs. (238.4 kg) maximum through 27 kV vs. 2450 Ibs. (1112.3 kg) in a comparable air-magnetic design for ease of handling.
Reduced Breaker Maintenance
Vacuum interrupter requires only periodic check for contact erosion. Integral wear indicator provided. No contact adjustments are required.
Front Accessible Mechanism
Front accessible mechanism is standard on all VCP-W breakers.
Front Accessible CTs (5-27 kV)
Up to 12 CTs per breaker can be mounted for easy access.
Drawout Auxiliary Compartments
Up to 4 drawers per vertical section can be equipped with CPTs or VTs up to 15 kV. Primary isolation shutters are standard.
Fluidized Bed Epoxy Bus Insulation
Excellent track resistant and flame retardant properties.
Standardized Functional Designs
Shortens order cycle time.
