Main characteristic

• Superior conductance system: Conductive part made of Al-alloy of high conductance rate is characteristic of good conductance, high mechanical strength, light weight and strong corrosion resistance. The current will pass through the foldable area of the conductive arm via soft connection (without any movable contacts) to ensure reliable conductance, few maintenance, no examination, and long-term reliable operation.
• State -of-art structure: The switch disconnector is in the single-arm, foldable and telescopic structure, The driving elements and balancing springs are sealed within the conductive tube to reduce their adverse effects on natural environment and render the appearance compact and simple. The drive base adopts a link lever, Compared with angular wheels, the product is simpler and easier to adjust
• Simple and superior grounding switch: 363kV earthing switch is in the single-arm standing and openable structure, with the structurally simple plug-type contact. The conductive rod for grounding will move in two steps at the moments of opening and closing. At the moment of opening, the conductive rod will rotate vertically and rise up to the static contact, and then automatically plug itself into the star-shaped contact. By doing so, the contact will be made reliable and be able to sustain heavy short-circuit current.
• Plug-type contact: The moving contact is the plug-type and has the self-cleaning ability. One end of the U-shaped finger of 126kV and 252kV fixed contact is fixed onto the contact base, forming a fixed connection and ensuring the reliable conduction; while the other end will produce contact pressure on the moving contact as a result of the influence of external spring and the own elastic force of the contact finger, and the gripping force will automatically increase when the short-circuit current passes through the contact. The contact spring is made of stainless steel and is equipped with insulating gasket. The spring will not corrupt nor shunt. The arc contact can be mounted onto the movable and fixed contacts to enable the disconnect switch to switch current, capacitive and inductive current by opening and closing bus line.
•  Provide one-key sequential control "double confirmation" function expansion.
