Porcelain Fuse cutout ISO 9001

Product Features of RWG15-12, RWG15-24,RWG15-27 Fuses
1. características do produto
(1) This product uses high-strength porcelain material as the insulator, with a strength of 16kN.
(4) The switch action part is a die-cast copper part, a glass fiber filament wound pipe.
(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) The dual exhaust structure is adopted. When breaking a small current fault, the lower end is vented by a single hole. When breaking a large current fault, the top of the hat will be broken. At this time, it cannot fix the top connector of the fuse, so The pressure relief cap cannot be reused.
2. Conditions of use
(1) Altitude: no more than 1500m
(2) Maximum wind speed: no more than 35m / s
(3) Temperatura ambiente: -40 ℃ ~ + 40 ℃
(4) Ice thickness is not greater than: 10milímetros
(5) seismic intensity: Nível 8
(6) Pollution level: Class IV
3.Executive standards
Meet the technical requirements of GB / T 15166.3-2008 and related regulations.

4. Raw materials
This product is mainly divided into a base and a falling part. The base is made of high-strength porcelain, metal accessories and falling parts.
5.Usar
RWG15 series drop-out fuses are widely used in the primary side of 10kV distribution lines and distribution transformers with a capacity below 36kVA as backup protection and for 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.
