Product Description

 We customize our products according to customer requirements.
1 Overview
     GW7F series disconnector is the three colums,double break,horizontally reverse type  structure,applied to the electrical system of rated frequency 50Hz or 60Hz, used in HV lines transfer in free of load condition and electric disconnection for maintenance of HV  busbar,circuit breaker and live HV lines,etc.
     GW7F Series HV AC disconnector is composed of three poles. Each pole is 3 columns structure, consisting of pedestal, pillar insulator, main blade, static contact-head of main blade, etc. Three pillar insulators separately are vertically installed on pedestal. The main blade is installed on the top of middle pillar insulator. Other 2 static contact-head are installed on the top of side pillar insulator. When main blade on the top of middle pillar insulatorhorizontally rotates for 70 degree, moving contact will insert into static contact then reverse for 45 degree, which makes static contact-fingers clamp the moving contact to finish one blade closing operation. For opening blade operation, vice versa.

4 Main feature
     Disconnector adopts reverse type, the conductive tube is two-step operation which enables the moving contact-head to reliably connect the contact-finger. Few operational force, stable manipulation and no impact force on side pillar insulator. Main contact-head has self cleaning ability.
     The contact-finger side in static contact pedestal fixed on contact-head pedestal, which combined fixed coupling for reliable conductivity. Other contact-finger side generates contact pressure on contact-head through itself elasticity and external-pressured spring. It will automatically strengthen clamping force when short circuit current passes by. Contact-finger spring is made of stainless steel material with insulating pad, which avoiding the spring rust and shunt.
      Hooking plate is placed on static contact-head. When blade closed, it will lock the moving contact-head and not let it take off even under the circumstance of gale, vibration and power effect. Reverse mechanism of conductive tube is enclosed type, with anti-rain, anti-dust, anti corrosion, to operate correct and reliable.
       Splint and hoop connected mode is adopted between main blade mechanism and vertical lever which connecting the body, and horizontal lever which connecting three poles of earth blade instead of soldering in working site. Horizontal lever which connecting three poles of main blade adopts positive and negative thread contact connection, which realized poleless adjustment, avoiding soldering and drilling in working site. It is both convenient for customer to installation, debugging, dis-assembly and maintenance in working site, and avoiding
corrosion and rust caused by soldering.
