Kechang Electric - XGN66-12 Ac metal armouring removable switchgear

HV&LV switchgear
XGN66-12 AC metal-clad move-open switchgear is a kind of high-voltage switchgear, which is mainly used in 3.6-12kV three-phase AC 50Hz system as a device for receiving and distributing electric energy.XGN66-12 switchgear is suitable for places of frequent operation and Rongji switchgear modification which needs to be equipped with oil switch. Its features include small size, high reliability of circuit breaker, good performance, and five-proof interlocking mechanism, etc.12 In addition, the equipment is suitable for the use requirements of various types of power plants, substations (offices) and industrial and mining enterprises.

High reliability and long service life: the device adopts high-quality raw materials and advanced production technology to ensure the stability and long service life of the product.
Good operating performance: its operating mechanism is reasonably designed, easy and smooth to operate, and has a good sense of touch.
Wide current range: the current range of XGN66-12 is generally between 12A and 630A, which can meet the needs of different users.
A variety of installation methods: the device has a variety of installation methods to choose from, which is convenient for users to install according to actual needs.
Perfect “five-proof” function: the interlocking between main switch, trolley and cabinet adopts mandatory mechanical interlocking, which meets the “five-proof” function, i.e., preventing pushing and pulling the breaker trolley with load, preventing mis-splitting of the breaker trolley and preventing mis-splitting of the breaker trolley, which is the most important function of the equipment. Circuit breaker trolley, preventing mistakenly opening and closing the circuit breaker, preventing the earth switch from closing the circuit breaker in the closed position, preventing mistakenly entering the energized isolation room, and preventing mistakenly closing the earth switch when energized.
High protection level: The protection level of the enclosure is IP4X, and the protection level is IP3X2 when the door of the trolley compartment is open.
Structural features and materials: the cabinet is assembled by cold rolled steel plate, high precision, easy for mass production; equipped with all new composite insulated vacuum circuit breaker, the circuit breaker adopts the handcart floor-standing structure, featuring good interchangeability and simple replacement.
Applicable environment: applicable to the surrounding air temperature between -10 ℃ and +40 ℃, altitude of 1000m or less, relative humidity is not greater than 95% of the environment.
