DMNS low-voltage switchgear
DMNS system is based on the absorption of foreign MNS system manufacturing technology, research and development of products.
DMNS low-voltage switchgear (referred to as switchgear) by the power center (Pc) and motor control center (MCC) is composed of two parts. Suitable for AC 50-60Hz, rated voltage 660V and below power distribution control system. For power plants, substations, industrial and mining enterprises such as power users, power distribution, motor control and lighting distribution equipment for power conversion for distribution control.
The cabinet except for general land after special treatment can also be used for offshore oil drilling platform and nuclear power stations.
It conforms to IEC439 VCE0660 500th and GB7251-05 "low voltage switchgear" with standard JB/T9661-1999 "low voltage withdrawable switchgear industry standard".
Product features
The structure is compact, functional unit in the smaller space can accommodate more users, saving investment.
The cabinet can back-to-back arrangement, the same cabinet can be freely combined into the same form and draw out two types.
The structure is universal, flexible assembly, according to the different requirements and work environment, design the corresponding level of protection.
The selection of all series of standard modules, standardization, convenient for engineering design personnel design selection.
The unique design of the mechanical locking mechanism, flexible and convenient operation, do not need special tools.
The extensive use of high strength flame retardant engineering plastics components, operation personnel safety and security.
According to the cable outlet in different ways, can choose the cable side outlet or after outlet two schemes.
The technology of high performance, the main parameters of technology to achieve the level of contemporary international.
