The GW9-10 high voltage hooksticks are typically used in high
voltage transmission and distribution systems to isolate sections
of the network for maintenance or repair work. They are also used
as a safety device to protect workers from electrical hazards, such
as accidental contact with live parts of the system.
They are designed to handle high voltages and currents, and they
are often installed in outdoor locations, where they are exposed to
harsh environmental conditions, such as extreme temperatures, wind,
rain, and dust. Therefore, they are built to withstand these
conditions and are often made of durable materials such as steel or
High voltage ehooksticks come in different types and
configurations, depending on the specific application and
requirements. For example, some hooksticks are designed for indoor
use, while others are suitable for outdoor use. Some are designed
to operate manually, while others are automated and can be operated
In addition to their primary function of isolating circuits,
hooksticks also have other important features, such as providing a
visual indication of their status (open or closed), and ensuring
that the circuit is not energized when the isolator is open.
Double effect of using when GW9-10 series isolator swich can be
used with the vacuum circuit breakers.

1.The ZW20-12(F) automatic vacuum circuit breaker is designed to
operate reliably within a wide ambient air temperature range, from
-40 °C to +70 °C. This temperature tolerance ensures that the
circuit breaker can function effectively in various climatic
2.The circuit breaker is suitable for installation at altitudes not
exceeding 3000 meters above sea level. This altitude compatibility
allows for flexible deployment in different geographic locations.
3.The ZW20-12(F) circuit breaker is built to withstand ambient air
contamination caused by dust, smoke, corrosive gases, steam, or
salt spray. It is designed to meet Class IV contamination level
standards, ensuring that the circuit breaker remains resilient and
operational even in challenging and corrosive environments.
