Product Detail

Description :

MNS LV withdrawable switchgear (hereinafter referred to as device) is manufactured by standard module through consulting MNS series low voltage switch cabinet of Switzerland ABB Company, and synthetically improved. The device is applicable to the system with AC 50Hz, rated working voltage 660V and below, used as control device for various power generation, transmission, distribution, power transfer and power consumption device.

It is widely used in low voltage distribution system of various mining enterprise, tall building and h otel, municipal construction etc. Besides the general land use, after special disposal, it also can be used for marine petrol drill taken platform and nuclear power station. The device accords with international standard IEC439-1 and national standard GB7251.1.

Main feature :

  • Compact design: Contain more function units with less space. 

  • Strong versatility for structure, flexible assembly. C type bar section of 25mm modulus can meet the demands of various structure and type, protection grade and operating environment. 

  •  Adopt standard module design, can be combined into protection, operation, transfer, control, regulation, measurement, indication etc such standard units. User can choose assembly according to requirement at will. Cabinet structure and drawer unit can be formed with more than 200 components. 

  • Fine security: Adopt high strength antiflaming type engineering plastic pack in large quantity to effectively enhance the protective safety performance. 

  • High technical performance: Main parameters reach the advanced level at home.

Main technical parameters:

Conditions for normal operating environment:

  • Ambient air temperature: -5℃ ~+40℃  and the average temperature should not exceed +35℃  in 24h.

  • Air condition: With clean air. Relative humidity should not exceed 50% at +40℃  . Higher relative humidity is allowed at lower temperature. Ex. 90% at +20℃ . But in view of the temperature change, it is possible that moderate dews will produce casually. 

  •  Altitude above sea level should not exceed 2000M. 

  • The device is suitable to the transportation and store with following temperature :-25℃  ~+55℃  , in short time (within 24h) it reaches +70℃  . Under the limiting temperature, device should not suffer damage that can' t recover, and it can works normally under normal conditions.

  • If the above operating conditions not meet user's demand. Consult with manufactory.

  • Technical agreement should be signed additionally if the device is used for marine petrol drill taken platform and nuclear power station.

Q:What is withdrawable switchgear?

A:Withdrawable switchgear is a type of electrical switchgear that allows the circuit breaker and other components to be easily withdrawn from the main body of the switchgear for maintenance, repair or replacement without having to disconnect the entire power supply system. It enhances the flexibility and maintainability of the power system.

What is the difference between a dielectric and an insulator?
What is the difference between a dielectric and an insulator?
Dielectrics and insulators are distinguished primarily by their applications. One of the main differences is that a dielectric can store electrical energy by becoming polarized in an electric field, whereas an insulator resists the flow of electrons to prevent current conduction. Other key differences between them are outlined in the comparison chart below.Definition of DielectricA dielectric material is a type of insulator that contains few or no free electrons. When subjected to an electric fi

Fault Analysis and Treatment of Oil-Immersed Transformers
Fault Analysis and Treatment of Oil-Immersed Transformers
Oil Leakage at Welded JointsOil leakage at welded joints primarily stems from poor welding quality, such as incomplete or detached welds, and defects like pinholes and gas pores. Although oil-immersed transformers are initially coated with solder and paint during manufacturing, potentially masking these issues temporarily, the defects tend to surface during operation. Additionally, electromagnetic vibration can cause weld cracks, leading to oil leakage.To resolve such leaks, the first critical s

What losses occur during operation of the transformer? How to reduce losses?
What losses occur during operation of the transformer? How to reduce losses?
Transformers experience various types of losses during operation, primarily categorized into two main types: copper losses and iron losses.Copper LossesCopper losses, also known as I²R losses, are caused by the electrical resistance of the transformer windings—typically made of copper. As current flows through the windings, energy is dissipated in the form of heat. These losses are proportional to the square of the load current (I²R), meaning they increase significantly with high

I. Methods for Cable Testing and Inspection:Insulation Resistance Test: Use an insulation resistance tester to measure the insulation resistance value of the cable. A high insulation resistance value indicates good insulation, while a low value may suggest insulation problems requiring further investigation.Voltage Withstand Test: Apply a high-voltage test using a high-voltage tester to verify whether the cable can withstand high voltage under its rated operating conditions.
