VOX OUTDOOR BREAKER
Low cost of ownership, with a proven track record
VOX
Electrical distribution companies are facing ever-increasing challenges to improve the service quality and reduce operation cost of their network.
VOX outdoor dead tank circuit breakers provide a reliable, cost effective solution for outdoor substation up to 38kV.
The sealed-for-life, maintenance-free tank enables customers to reduce the cost of inspection and maintenance. In addition, the high-endurance mechanism contributes to further enhance the reliability of VOX reducing overall lifetime costs.
Flexible and easy to upgrade, VOX is the ideal, cost-effective choice for both dead and live tank applications, especially when complex protection and current transformer schemes are needed.
A NEW GENERATION OF DEAD TANK CIRCUIT BREAKERS
​
VOX combines the best new and proven technology for outdoor distribution applications up to 38 kV.
The VOX uses latest range of vacuum interrupters housed in a fully welded, sealed-for-life, stainless steel tank, providing a controlled gas insulated environment totally immune from external ambient conditions. A spring charged mechanism provides manual or motorized circuit breaker operation.
Features & Benefits:
-
Reduced life-time costs/Minimal maintenance required
-
Sealed for life design
-
Small footprint for distribution breakers from 25.8 kV and above
-
Internal arc tested in compliance with IEC 62271-200 featuring accessibility class A. Test has been performed with low voltage door in open and close position to ensure maximum operator protection covering the requirement of type 2B as per IEEE C37.20.7
-
Out-of-phase switching for decentralized generation (windfarms)
-
Suitable for high-speed auto-recloser switching
-
Suitable for capacitor bank switching Class C2 (Recommended for capacitor Bank switching).
-
ANSI/IEEE “rain tested” enclosure (ANSI/IEEE C37.20.2)
-
EPDM bushing with creepage distance of more than 31.5mm/kV
-
Build with proven, highly reliable vacuum interrupter assemblies mounted inside the SF6 filled tank

EASE OF INSTALLATION
The compact, lightweight design of the VOX makes it easy to transport, handle and install.
The separate support frame can be pre-installed to accept the breaker tank and the control cabinet. Height can be adjusted within a range of 27 inches (675 mm).
EASE OF USE
Provisions for current transformers is available on all six polymer bushings which are external from the sealed circuit breaker tank.
Mechanical circuit breaker and spring status indications are easily viewable from ground level. An easily accessible cabinet houses the operating mechanism, control and protection equipment, with ample space to accommodate auxiliary equipment.
