Products
The EGLD series DC disconnectors are suitable for power systems with a rated voltage of DC1000V/DC1500V or below and a ratedoperating current of 630A or below. The product can be used for infrequent switching on and off, functioning to isolate and interrupt circuits to facilitate equipment maintenance or overhaul. It is widely applied in various industries such as construction, electric power, andmetallurgy.
The contacts adopt a rotating double-end contact structure, ensuring the safe distance of the disconnector, meeting the requirement ofreliable isolation, and the contacts have a self-cleaning function.
· Double-spring operating mechanism: The double-spring energy storage mechanism realizes fast switching on and off. The switching effect is not affected by the operator’s speed, improving the breaking speed.
· The shell is made of glass fiber unsaturated polyester resin, which has excellent flame retardancy, dielectric properties, anti-carbonization performance, and impact resistance.
· Complies with the latest EU RoHS directive.
·The operating mechanism supports front-side and side-side operation.
· The arc-extinguishing system adopts the arc-extinguishing principle of permanent magnetism to increase arc voltage, improving the breaking performance.
