Current position: Orient > model >


There are much equipment for transmission and distribution systems. Disconnectors are one of high voltage instrument for application in electric utility with high quality and competitive price.


Disconnectors are normally used in substations, the types of disconnectors have
◆ Horizontal Double Break
◆ Vertical Break
◆ Horizontal Centre Break
◆ Pantograph

Main specifications of disconnectors
◆ Current Ratings: Up to 4000A
◆ Voltage Class : Up to 550 kV
◆ Motor or manual operating mechanism
◆ Single-pole or three-pole operated units

The benefits of disconnectors
◆ Maintenance-free dry lubricant bearings
◆ Hardware on live parts are made of non-magnetic materials
◆ Interlocks for safety
◆ High strength hot dip galvanized steel base
◆ Current-carrying parts are made of high-conductivity extruded aluminum
◆ Low maintenance and installation costs
◆ Ice breaking capacity

Disconnectors are manufactured as per ANSI, IEC, BS, CAN and other international standards or related standards with high mechanical and electrical properties.
