Advantages

1. The 12KV Porcelain Fuse Cutout is come with a high precision fuse that melts within 0.1 seconds in the event of a short circuit/overload, quickly cutting off the faulty circuit; The drop type structure intuitively displays the fault status, making it easy for operation and maintenance personnel to quickly locate and repair, and avoiding the expansion of faults.

2. Ceramic insulators have excellent high and low temperature resistance, UV resistance, and moisture resistance, and can work stably in environments ranging from -40 ℃ to 85 ℃ for a long time; Brass and stainless steel materials are suitable for harsh environments such as coastal salt spray and industrial dust, with a service life of ≥ 15 years.

3. The fuse cutout has standardized installation interfaces and is compatible with various installation methods such as crossarms and brackets; All models cover voltage levels of 10kV-38kV and are compatible with different distribution lines, distribution transformers, box transformers, and other equipment to meet the needs of multi scenario power distribution.

Applicable scenarios

1. Branch protection for 10kV/20kV/35kV outdoor distribution lines in urban and rural areas

2. High voltage side incoming line protection for distribution transformers (applicable to both oil and dry transformers)

3. Safety protection for high-voltage side of box transformers in photovoltaic power plants and wind farms

4. Outdoor high voltage power supply system for industrial and mining enterprises and industrial parks

5. Supporting equipment for rural power grid renovation and upgrading

Key points for installation and maintenance

1. Installation requirements

Before installation, check that the fuse specifications of the 12KV Porcelain Fuse Cutout match the rated current and there is no damage or rust

Vertical installation, drop angle of 30 °± 5 °, ensuring reliable drop in case of malfunction

Tighten the wiring terminals, ensure good conductive contact, and avoid overheating caused by virtual connections

2. Maintenance suggestions

Inspect every 6 months to check for cracks in insulators and rust on conductive components

After the fuse is blown, it is necessary to investigate the cause of the fault and replace it with a fuse of the same specification before closing it

Shorten the inspection cycle in coastal and heavily polluted areas, and promptly clean the dirt on the surface of insulators

FAQ

How to choose the appropriate model?

Everyone needs to choose the corresponding model based on the rated voltage of the distribution system (10kV/20kV/35kV) and the rated current of the line (6A-10A), such as SJC-1 for 10kV lines and SJC-13/13B for 35kV lines.

How to replace a blown fuse?

Disconnect the power supply of the circuit, open the moving contact of the fuse, remove the old fuse, install a new fuse of the same specification, and close the contact. The operation is simple and does not require professional tools.

How long does the product warranty last?

2-year warranty, during which non-human damage can be replaced free of charge; Provide lifelong technical support to meet the needs of power grid upgrading and transformation.
