Ring Main Unit is a compact and comprehensive solution suitable for secondary distribution networks up to 24kV, requiring little maintenance and minimal space. It has many applications in wind power plants, small industries, construction, mines, airports and Underground facilities.

Feature:

1. Technology

Metal enclosed unit for indoor installation and type tested.

Insulated by SF6 gas.

Maintenance-free and easy to install.

Not affected by climate.

On-off-ground, three-position load disconnect switch.

Use recyclable materials.

2. Security

When there is electricity in the cable, it can be easily accessed and operated safely.

The operating status is clearly indicated through the mimic diagram on the front panel.

Fully automatic interlocking system.

Operate only when the door is completely closed.

The fuse box can only be used when the load disconnect switch is grounded.

Voltage detector to check whether the cables are arranged.

The rupture disk is designed to protect equipment in emergency situations such as gas expansion.

If an unexpected current occurs, safety tests are carried out on the internal arc tolerance to ensure the safety of the operator. (21kA / 1s, no SF6 gas)

3. Durability and practicality

The metal closed tank is airtight. This means that it is not affected by the environment, such as dirt, small insects, moisture, etc.

The front part of the ring main unit can be operated with load disconnecting switch.

The interlocking system can be operated automatically according to the operator's position, so all switch operations can be performed on the personnel safely.

Charging is not required until the service life of SF6 gas.

Remote operation possible when using motor operating mechanism

In the event of a failure, the power fuse will automatically trip the mechanism by striking the pin of the fuse connected to the mechanism.

4. Save costs

After installation, no maintenance is required except to replace the power fuse.

The compact design requires minimal space for local installation and operation, which is its main advantage, especially where space is limited.

Due to the long service life, there is no need to pay additional replacement costs.

Materials can be recycled after the end of the service life.
