Product Description:

The ZW20 series boundary vacuum switch is a type of electrical switch that operates in a vacuum environment. It is designed for medium voltage applications and is commonly used in power distribution systems.

The switch is typically constructed with a robust and durable enclosure made of high-quality materials. It incorporates a vacuum interrupter chamber, current-carrying contacts, and control mechanisms.

And the vacuum interrupter is the key component of the switch. It consists of a sealed vacuum chamber that contains two contact electrodes. When the switch is closed, the vacuum environment prevents the formation of an electrical arc during switching operations.

It is equipped with a mechanism for opening and closing the contacts. It can be operated manually or electrically, depending on the model and application requirements. The operating mechanism ensures smooth and reliable switching operations.

The ZW20 series boundary vacuum switch is available in various voltage and current ratings to suit different system requirements. It can handle medium voltage levels typically ranging from several kilovolts to tens of kilovolts.

The switch has a high breaking capacity to interrupt fault currents and protect the electrical system. The breaking capacity is specified in terms of the maximum fault current that the switch can safely interrupt without damage.

Some models of the ZW20 series may offer advanced control and monitoring features. These features can include remote control capabilities, status indication, and fault diagnostics, providing enhanced functionality and ease of operation.

The vacuum technology used in the switch ensures excellent arc extinguishing capabilities, making it a reliable and safe solution for medium voltage applications. The switch is designed to meet stringent safety standards and provide long-term performance with minimal maintenance requirements.

The ZW20 series boundary vacuum switch is suitable for a wide range of applications, including power distribution substations, industrial plants, commercial buildings, and more. It is commonly used for load switching, fault protection, and isolation in medium voltage electrical systems.

GW9-10 overhead disconnect switch is a portable, high-voltage electrical switch used to isolate electrical circuits for maintenance and repair purposes. It is typically used in medium to high voltage power transmission and distribution systems.

The overhead disconnect switch is designed to be portable and can be easily transported to the location where it is needed. It is capable of handling high voltage levels, typically ranging from a few kilovolts to several hundred kilovolts.

The switch is used to isolate a section of the power system for maintenance or repair purposes. It has visual indicators that show whether the switch is open or closed, making it easier for operators to know the status of the circuit.

The Loadbuster Electrical Isolator can be used for a wide range of applications, including switching and isolating circuits, as well as for grounding and de-energizing equipment. It is designed with safety features to protect operators from electrical hazards, such as insulating materials that prevent accidental contact with live parts.

The switch is easy to use and requires minimal training to operate. It has interchangeable blades that can be easily replaced, allowing for greater flexibility and versatility.
