VDM6-12 type indoor high voltage vacuum circuit breaker with permanent magnetic mechanism, the indoor switchgear with the rated voltage of 12Kv and the three-phase alternating current 50Hz, is used to switch on/ off all kinds of electrical load with different nature and suitable for the electrical network construction and reform projects for city network, country network, mining area and railway etc. especially for the fields that takes the frequent operation within the range of working current and have the strict demand on short-circuit drop-out operating times. This product absorbs the advanced technology and technics home and abroad to be intelligentized, greatly reliable, longevous and maintenance-free. There are two types of structures of fixed installation style and draw-out hand buggy style, and no pollution for surroundings when using, a green product for environmental protection.
This products is in conformity with the standards of GB311.1-311.6, CB1984,GB2706,GB/T3309,GB7675,GB/T11022,JB3855,DL402 | |
