HRW12-12 outdoor high voltage drop fuse
Product Details
Product overview
Outdoor high-voltage drop fuse is a short-circuit protection switch commonly used in 10kV distribution line branch line and distribution transformer. It has the characteristics of economy, convenient operation and strong adaptability to outdoor environment. It is widely used in 10kV distribution line and primary side of distribution transformer for protection and equipment switching and cutting operation.
The drop fuse is installed on the branch line of the 10kV distribution line, which can reduce the power failure range. Because it has an obvious disconnection point and has the function of an isolating switch, it creates a safe working environment for the lines and equipment of the maintenance section and increases the safety of the maintenance personnel. Installed on the distribution transformer, it can be used as the main protection of the distribution transformer, so it has been popularized in the 10kV distribution line and distribution transformer.
