| GGDLow voltage fixed type switchgear cabinet |
Overview:
Type GGD![]() AC low voltage distribution cabinet is based on the higher charge of the Department of energy, the power users and the requirements of the design department, in the light of the new low voltage distribution cabinet design principles of safety, economy, reasonable and reliable. The product has a high breaking capacity, good thermal stability, electrical scheme flexible, convenient combination, series resistance, strong practicability, novel structure, high level of protection. Can be used as a replacement of low voltage switchgear products.
Applicable scope:
Type GGD AC low voltage distribution cabinet for power plants, substations, industrial enterprises and other power users of AC 50HZ, rated voltage 380V, rated current distribution coefficient to 3150A, as power, lighting and power distribution equipment, power conversion, distribution and control purposes.
Type GGD AC low voltage distribution cabinet produced by our company in accordance with IEC439 "low voltage switchgear and control equipment", GB7251 "low voltage switchgear and control equipment" and other standards.
The conditions of use:
The ambient air humidity not higher than +40 degrees Celsius, not less than -5 degrees celsius. The average temperature within 24 hours shall not be higher than +35 degrees celsius.
Indoor installation, use the site altitude not exceeding 2000m.
The relative humidity of ambient air in the maximum temperature of +40 degrees Celsius is less than 50%, in the low temperature allows high relative humidity. (for example, +20 degrees Celsius to 90%) should be taken into account due to the effect of temperature changes may happen.
When installing the device and the vertical plane inclination of not more than 5%.
The equipment should be installed in the absence of severe vibration and shock, and lack of the electrical components from corrosion sites.
If users have special requirements can be resolved through consultation with my company.

| GCS low-voltage switchgear | |
Overview:
GCS type low-voltage switchgear is the electric power industry ministry, the Ministry of machinery industry to promote technological progress of China's low-voltage distribution industry, accelerate the low-voltage switchgear upgrading, protect and promote our national industry for the purpose, commissioned in 1995 two Senyuan electric limited company organization GCS low-voltage switchgear co the design team to complete the design and development, currently in the country has obtained preliminary affirmation and selection.
Applicable scope:
This device is suitable for power plants, substations, Petrochemical Department, factories and mines, high-rise buildings and other low-voltage distribution system, power distribution and motor control center, capacitor compensation and other power conversion, distribution and control.
In the capacity of power plants, large-scale petrochemical industries such as power control center and motor control center power occasions can meet the special needs and computer interface.
The device is based on the electric power department supervisor, general electric power users and the requirements of the design department, in order to meet the development of the electric power market, power capacity to computer interface, centralized control, convenient installation and repair, shorten the processing time of the accident and other needs, in the light of the new design principles of safety, low economic, reasonable, reliable switchgear. The product has broken through, high capacity, good dynamic stability, flexible, convenient combination, electrical program series of practical, novel structure, high level of protection. Can be used as low-voltage switchgear products use.
I produced the GCS device with IEC-1 "low voltage switchgear and control equipment," GB7251 "low voltage switchgear and control equipment," ZBK36001 "low voltage withdrawable switchgear" standard.
The conditions of use:
The ambient air temperature is not higher than +40 degrees Celsius, not less than -5 degrees celsius. The average temperature within 24 hours shall not be higher than +35 degrees celsius. Over time, according to the actual situation of step-down operation.
Suitable for indoor use, the altitude of the site shall not exceed 2000m.
The relative humidity of ambient air in the maximum temperature of +40 degrees Celsius is less than 50%, in the low temperature allows high relative humidity, such as +20 degrees Celsius for 90%, due consideration should be given to the influence of temperature change may occasionally products.
During the installation of the vertical and plane inclination of not more than 5%, and the whole cabinet column relatively smooth (GBJ232-82 standard).
The device should be installed in the absence of severe vibration and shock and insufficient to make electrical components should not be subject to corrosion.
The user has the characteristics of the requirements, can be resolved in consultation with the manufacturer.
