Product details
product description
The outdoor high voltage AC drop fuse is the most commonly used short circuit protection switch of 10kV distribution line branch line and distribution transformer. It has the characteristics of economy, easy operation and strong outdoor environment. It is widely used in 10kV distribution line And the primary side of the distribution transformer as a protection and equipment investment, cutting operation purposes
Features
The overall structure is rigorous and reasonable
The overall structure of the fuse design rigorous and reasonable, sophisticated materials, the assembly process is strict, the components with a stable and reliable, flexible action. Not only to ensure the reliability of product operation, but also to ensure that the operator can be very convenient and easy to operate.
High quality material
All accessories not only reasonable design, and are using high-quality materials, the use of advanced processing technology, product accuracy, interchangeability, and ensure the overall high-quality products.
Superior mechanical performance and fault breaking capacity
When the full gate operation, the melting tube precision in place, there will not be shaking, bounce, or trip phenomenon, the trip action is absolutely reliable, and has nothing to do with the size of the fault current, with a maximum 16kA short circuit fault breaking capacity.
Anti - UV water resistant pipe
The use of epoxy resin glass fiber winding tube and arc dielectric material composed of the melting tube, the outer layer of anti-ultraviolet outdoor paint, high mechanical strength, the effective use of long life, the appropriate geometric size, single-ended exhaust way to speed up the airflow speed , Improve the ability to blow the arc, which can meet the requirements of breaking large, small current.
Silver upper and lower contacts
Fuse on both ends of the conductive contacts, are silver on the silver structure, reduce the contact resistance, to ensure conductive reliability.
High strength silver plated copper trunnions and cast copper earrings
Casting silver-plated ear trunks and cast copper ear shell design, high strength, with tight and comfortable, flexible and avoid the closure of the molten pipe around the shaking.
Parallel trench terminal
Casting and silver plated parallel groove terminals, providing two pressure line groove, so that wiring is very simple and reliable.
Galvanized ice hood
The ice hood is designed to prevent rain from flowing over the stainless steel spring and the upper contacts, preventing the top of the fuse from moving due to freezing.
No upper and lower diversion pieces
Fuse the upper and lower ends of the conductive part, are used as a whole silver-plated copper, the middle without breaking points, greatly improving the product's conductivity and product reliability.
Stainless steel expansion force through the mandrel
Stainless steel coil made of stainless steel expansion force through the mandrel to ensure that the melting tube and casting copper trunnion connection stability and reliability, to ensure that the fuse when the melt pipe can accurately fall.
