 Product features of RWG12-12, RWG12-24~27,RWG12-33~36 fuse
1. Product Features
(1) This product uses high-strength porcelain material as the insulator, with a strength of 12.5kN.
(2) The switch contact is made of copper plate T2 material and stainless steel material.
(3) All the reserved standard parts are made of stainless steel (304 material)
(4) The switch action part is die-cast bronze, glass fiber filament winding tube.
(5) The lower contact of the melting tube is a flip contact design.
(6) The connection part of the insulator is made of hot-dip galvanized steel, which effectively prevents external forces from affecting the overall change of the switch.
(7) All contact surfaces are plated with silver to increase the conductivity of the product.
(8) Adopt downward exhaust structure to avoid the threat of free gas to the line.

4. Raw materials
This product is mainly divided into a base and a drop part. The base is made of high-strength porcelain and metal accessories (copper plate, S304 stainless steel, steel, etc.); the drop part is composed of cast bronze, arc extinguishing tube, and S304 stainless steel accessories.
5.Use
RWG12 series drop-out fuses are widely used in 10kV distribution lines and primary side of distribution transformers with a capacity below 36kVA as backup protection and system, equipment switching and switching operations. It is installed on the 10kV distribution line branch line, which can reduce the power outage. Because it has an obvious disconnection point, it has the function of an isolation switch, which creates a safe operating environment for the maintenance section lines and equipment. Even under load, operation of stopping and transmitting power is allowed.
