Product Description
15kv 24kv Polymer Drop Out Fuse Cutout Switch Creepage 485mm
The high voltage fuse cutout is a critical component designed for primary overhead feeder lines and taps. It serves to protect distribution transformers from potential short-circuits and overloads. When the electrical current surpasses a specified limit for a predetermined duration, the fuse is engineered to melt and activate the switch mechanism, visibly opening the circuit and safely disconnecting the transformer from the line. This product is renowned for its cost-effectiveness, ease of operation, and robust adaptability to outdoor conditions. Moreover, the cutout functions as an isolating switch, establishing a secure working environment for maintenance personnel on power lines and equipment.
Service Conditions
Altitude: Less than 1000m above sea level
Temperature: Ranging between -40ºC to +40ºC
Relative Humidity: Daily average does not exceed 95%, while monthly average remains below 90%
The installation site must remain clear of fire, explosion hazards, chemical corrosion, and intense vibrations.
Mounting Arrangement
The cutout is designed to be mounted with an optimal angle between 15° and 20° from vertical. It offers versatile mounting options on either steel cross-arms or poles. A strategically placed hole in the mounting bracket ensures the cutout can be securely fastened by a vertical bolt through the cross-arm's center line.
Packing
Standard packaging includes carton and pallet arrangements, ensuring your products are stacked securely for easy movement and storage, offering enhanced protection. Custom packaging solutions can be provided upon request, catering to specific user requirements.
