Product Overview

Air type plug box are more environmentally friendly, safer and easier to maintain

Air type plug box are an important part of the power system and play a role in connecting, disconnecting and protecting circuits. Different from traditional oil-immersed plug-in boxes, Air type plug box use air as the insulating medium, which is more environmentally friendly, safer and easier to maintain. These devices are commonly used in control and protection circuits in medium and high voltage power systems and offer several advantages over oil-immersed devices.

One of the main advantages of Air type plug box is that they are environmentally friendly. By eliminating the need for petroleum media, these devices reduce the risk of petroleum contamination and comply with modern environmental protection requirements. Not only does this reduce environmental impact, it also enhances the overall sustainability of the power system, making Air type plug box a responsible choice for circuit connection and protection.

In addition to environmental considerations, the safety of aviation-style junction boxes also deserves attention. Unlike oil-immersed cartridges, air-type models do not produce oil or leaks during operation, significantly reducing the risk of fire and explosion. This inherent safety feature makes air-mounted cartridges the first choice for safety-critical applications, giving operators and maintenance personnel peace of mind.

Additionally, Air type plug box are easy to maintain, setting them apart from traditional alternatives. There is no need to replace the oil medium regularly, which greatly reduces maintenance costs and workload. This convenience not only saves time and resources, it also helps improve the overall efficiency of electrical system maintenance, making Air type plug box a practical and cost-effective solution for circuit connection and protection.

Air type plug box have a series of compelling advantages in power systems. From environmental friendliness and enhanced safety features to ease of maintenance, these devices provide modern and efficient solutions for connecting, disconnecting and protecting circuits in medium and high voltage power systems. As the demand for sustainable, reliable power infrastructure continues to grow, the adoption of Air type plug box will play a key role in shaping the future of power system technology.

Plug-in Shunt System (Plug-in Box)

To cope with power distribution applications, RT-MYC wire busbar is a shunt box that can accommodate protective devices.

The plug-in system has undergone temperature rise and short-circuit testing and fully complies with international standards (IEC 439Parts1-1992) and national standards (GB7251.2Parts1-1997). The position of the shunt box can be designed

according to customer needs, and the 3.6-meter standard length linear component can accommodate up to 3 shunt points.

Plug in electrical boxes can be installed or removed under the power supply state of the busbar. The electrical box itself has enough space to connect wires. The electrical box is also equipped with special interlocks to prevent it from being opened or removed during use.

Characteristics of the shunt box for plug-in protective devices

Test standard: IEC439 Parts1-1992 GB7251.2 Parts1-1997

Rated current: 20 amperes to 400 amperes (plug-in or bolted connection)

400 to 800 amperes (bolted connection type)

Rated voltage: 500VAC (50Hz) (Customers can provide special requirements)

Safety design: The grounding contact is first connected to the wire busbar, allowing it to be energized

Install the safety lock for the box door, connect the wire harness and the lock for the electrical box connection
