G&W Viper® reclosers offer an economical alternative to circuit breakers at the utility grid. The solid dielectric, three phase vacuum reclosers provide overcurrent protection for systems up to 38kV, 800A continuous and 12.5kA symmetrical interrupting. Reclosers are available with a variety of mounting brackets for overhead and substation applications. Dead-front padmount configurations are also available. Other features include:
Dead-tank construction permitting the use of external CTs for SCADA monitoring or metering applications.
Control and relay flexibility including Schweitzer's SEL-351R, SEL-651R,
SEL-351S, GE's URC and others.
Tested to over 10,000 mechanical operations. Circuit breakers are typically limited to 2,000 operations.
Extremely fast operation. Typically a 4 shot sequence including a 4.5 cycle interrupting time takes under 5 seconds. Circuit breakers typically take up to one minute for a similar sequence.
Maintenance-free solid dielectric insulation compared to the routine maintenance required for gas or oil filled breakers.
Fully tested to ANSI/IEEE and IEC standards.
Meets IEEE 386 standard for 200A and 600A separable connectors for padmount applications.
Through programmable control logic, Viper reclosers
can be configured for Fault Detection, Isolation and
Restoration (FDIR), and peer-to-peer communication
