12KV Solid Fuse Cutout

The SARAH Electric's high-quality 12KV Solid Fuse cutout is an essential protective component in power systems, with high reliability, windproof design, and wide compatibility. Whether it's routine maintenance or emergency replacement, we can provide solid support for your power equipment.

Product model and specifications

Model: SJC-36, SJC-37, SJC-38, SJC-39 (corresponding to different voltage levels and lengths)

Voltage level: 15kV, 24kV

Tube length: 242mm (15kV), 320mm (24kV)

Rated current: 100A, 200A (supported by some models)

Applicable fuse types: RW12, RW5, HGRW1, PRWG2 and other series drop out fuses

Material: The main body of the melting tube is made of high-strength insulation material (such as epoxy resin or ceramic), and the two ends are made of brass or copper alloy conductive parts

Feature

Some models (such as RW5 and HGRW1) have windproof structures, suitable for harsh outdoor environments, to prevent misoperation caused by wind.

After melting, the melting tube automatically drops, forming a clear disconnection point for easy maintenance and fault location.

The 12KV Solid Fuse cutout uses high-quality insulation materials and precision machining processes to ensure stable operation in high voltage and high current environments.

Suitable for various brands and models of drop out fuse bases, such as SJC-36/1, SJC-37/2 and other accessories.

Application

The 12KV Solid Fuse cutout is used for the protection of transformers, capacitors, cable branch boxes, and other equipment in 10kV, 15kV, 24kV, and 35kV distribution networks.

Suitable for protecting high-voltage equipment in factories, mines, oil fields, and other places.

Solid Fuse cutout is particularly suitable for areas with strong sandstorms and high humidity, such as the northwest and coastal regions.

Installation and maintenance

Installation steps:

1. Please confirm that the fuse base model matches the fuse tube before installation (such as SJC-36 corresponding to RW12-15kV).

2. Insert both ends of the melting tube into the static contacts of the base to ensure good contact.

3. Check if the melting tube is firm, free from looseness or tilting.

Maintenance suggestion:

Regularly inspect the appearance of the melting tube, and replace it promptly if there are cracks, erosion, or deformation.

Check whether the base contacts are oxidized or worn, and clean or replace them if necessary.

Conduct preventive tests before thunderstorm season to ensure that the fuse characteristics meet the requirements.

FAQ

How to choose a suitable melting tube?

Select the corresponding model based on the system voltage level (e.g. SJC-37 for 15kV and SJC-39 for 24kV).

Select the rated current (100A or 200A) based on the load current.

How to replace a blown fuse tube?

First, disconnect the power supply and use an insulated operating rod to remove the melted fuse tube.

When installing a new melting tube, ensure that both ends are in full contact with the base contacts to avoid virtual connections.

Do you support windproof fuses?

Yes, models such as SJC-36 and SJC-37 can be compatible with windproof fuse bases, such as HGRW1-35kV.
