2019 wholesale price Fully Sealed Fully Insulated Inflatable Ring Network Switchgear
Overview
GCS low-voltage draw-out switchgear (hereinafter referred to as device)is a low-voltage draw-out switchgear developed by the ioint design team of the former Ministry of Machineryand the Ministry of Electric Power according to the requirements of the competent departments of the industry.the vast number of power users and designunits,which conforms to the national conditions, has high technical performance indexes,can meet the development needs of the power market and can compete with the existing imported products. In July, 1996,the device passed the appraisal jointly sponsored by the two departments in Shanghai,and was valued and affirmed by the manufacturing units and power users.
This device is suitable for power distribution system in power plant,petoleum,chemical industry,metallurgy,textile,hich-rise building and other industries.In large-scale power plants,petrochemical systemsand other places with high automation degree,which require computer interface, it is used as a low-voltage jacketed power distribution device for power distribution,motor centralized control and reactive power compensation in power generation and power supply systems with three phase AC 50(60)Hz,rated working voltage 380V and ratedcurrentof4000A orless
The device meets IEC439-1 and GB7251.1standards.
Main feature
- Main framework adopts 8MF bar seel.Both sides of bar steelis intalld with9.2mm mounting hole with modulus 20mm and 100mm.Inner istallation is flexible and easy;
- Two types of assembly form design for main framework,full assemblystructure and partial(side frame and cross rail)welding structure for user selection;
- Each function compartment of device is separated mutually.The compartments are divided into function unit compartment,bus bar compartment and cable compartment Each one has relative independent function;
- Horizontal bus bar adopts cuabinet back level placed array puttern for enhancing thecapacity of resisting electrodynamic force for bus bar It is the basic measure for obtaining high short circuitstrenath capacity for main circuits
- Cable compartment design makes cable outlet and inletupand down convenient

Use environment conditions
- Ambient air temperature:-5℃-+40℃ and the average temperature should not exceed+35℃in 24h
- Relative humidity should not exceed 50% at max temperature.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 leve should not exceed 2000M;
- Installation gradient not exceed 5°;
- Indoor without dust,corrosive gas and rain water attack

scheme
Remarks:
1.AH is the main circuit breaker,but other F and MT series circuit breakers witn more advanced performance or imported ones can also be startde.
2.01,02,04scheme,eg:when the pe+N needs to enter power cabinet,the width size adopts the one in the bracket.
3.SDL and SDH are special current transformers for BGCS cabinet.
