24KV Fuse Links

When using overhead distribution lines, transformer substations, etc., it is necessary for SARAH Electric to produce high-quality 24KV Fuse Links core protection components, which are used for rapid melting in case of line overload or short circuit faults, cutting off fault currents, and protecting the safety of transformers, lines, and electrical equipment.

This type of product has many specifications, covering 6A~200A full current specifications, and is compatible with ANSI/IEC standard drop out fuses. It is a core supporting consumable for power system operation and engineering construction.

Technical Specifications

Product series and core technical parameters

Full specification current coverage

SARAH fuses offer a full range of standard Preferred Rating and Non Preferred Rating specifications, covering 6 A、8A、10T、12T、15T、20T、25T、30T、40T、65T、80T、100T、140T、200T At full current levels, it can accurately match distribution systems with different voltage levels such as 10kV, 20kV, and 33kV, meeting the full scenario protection requirements from small capacity transformers in substations to main lines.

Core performance and ampere second characteristics

The 24KV Fuse Links are designed strictly in accordance with international standards, with core performance and ampere second (time current) characteristics as follows:

Conventional 10kV/12kV, 20kV/24kV, 33kV/36kV full range coverage, supporting customized higher voltage levels

6A~200A full specifications, meeting the protection and setting requirements of transformers and lines with different capacities

Provide precise fuse time current correspondence, delay fuse when overloaded, instantaneous fuse when short circuited, achieve selective protection, and avoid over level tripping

Suitable for a full temperature range of 40 ℃~+60 ℃, resistant to UV rays, humidity and heat, salt spray, and suitable for complex environments such as outdoor, coastal, and high-altitude environments

24KV fuse links adopt high-strength fuse core, high temperature resistant insulation tube body (paper tube/silicone rubber tube), stainless steel lead wire, anti tension, anti vibration, and long-term operation without aging

Advantages

The 24KV Fuse Links' ampere second characteristics strictly comply with international standards, and through precise alloy ratio and process control, achieve protection logic for overload delay and short circuit quick break:

When the line is slightly overloaded, delay the fuse to avoid misoperation and affect normal power supply.

When there is a short circuit fault, it quickly melts in milliseconds, instantly cutting off the fault current and protecting the transformer and line equipment.

The entire series of specifications have stable and consistent characteristics, meeting the selective protection requirements of the power grid and reducing the operation and maintenance trip rate.

Standardized size design, the fuse links compatible with mainstream domestic and foreign brands of drop out fuses, no need for customized modification.

Provide two types of insulation tube bodies: paper tube and silicone rubber tube. Paper tube is suitable for conventional environments, while silicone rubber tube is suitable for harsh environments such as high pollution, high humidity, and coastal areas.

Pre formed structure, standardized lead length, can be directly installed into drop out fuses for use, greatly improving operation and maintenance efficiency.

Application scenarios

1. High voltage side protection for 0kV/35kV distribution transformers, melting in case of overload or short circuit to prevent transformer burnout.

2. Branch and main line protection of 10kV/35kV overhead lines, cutting off the faulty section in case of failure to avoid affecting the power supply of the main line.

3. Photovoltaic and wind power grid connected lines, box transformer protection, suitable for outdoor complex environments of new energy projects.

4. High voltage distribution lines and motor protection in the factory meet the high reliability requirements of industrial scenarios.

5. Protection of railway electrification contact network and rail transit distribution system to ensure the safety of transportation power supply.
