Product description:
Use environment:
1 ambient air temperature is not higher than +40 DEG C, not less than -5. The average temperature in 24h shall not be higher than +35.
2 indoor installation, use the site altitude not exceeding 2000M.
3 relative humidity of ambient air in the highest temperature of +40 is less than 50%, in the low temperature allows relatively larger temperature (e.g. +20 DEG C for 90% should be taken into account due to temperature change may happen condensation effect).
4 equipment installation and vertical surface tilt is not more than 5%.
5 equipment should be installed in the place where there is no violent vibration and impact. And the place where the electrical components are corroded.
Feature use:
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 up to 3150A distribution system, as power, lighting and power distribution equipment, power conversion, distribution and control purposes.
GGD AC low voltage distribution cabinet is based on the requirements of the competent department of energy, the majority of users and the design department, in line with the principles of safety, economy, reasonable and reliable design of the low-voltage distribution cabinet. The product has the characteristics of high breaking capacity, good dynamic and thermal stability, flexible electric scheme, convenient combination, series, strong practicability, novel structure and high protection grade. It can be used as the replacement product of low voltage complete set of development equipment.

Two, model: GCS
The use of the environment: the device is applicable to power distribution system of power plant, petroleum, chemical, metallurgy, textile, building and other industries. Automation in large power plant, petrochemical system, high degree requirements and computer interface places, as the three-phase AC frequency of 50 (60) Hz, rated voltage of 380V (400), (600), the rated current is 40000A and below the power generating and supply system, electric centralized control, no motivation reactive power compensation using low capture distribution equipment.
Purpose: to improve the capacity of heat transfer characteristics of parts, greatly reduced due to the temperature rise to the attached adapter connector, cable head temperature, bring up the partition.
The separation between the functional units and the compartments is clear and reliable, and does not affect the work of other units due to the fault of a unit, so that the fault is limited to the minimum range.
Bus flat arrangement makes the device dynamic and thermal stability, can withstand the impact of 80/176KA short-circuit current.
The number of the circuit of the MCC cabinet is more than 22, which fully takes into account the needs of the large single capacity power plant, petrochemical industry and other industries.
The device is connected with the external cable in the cable compartment. Zero sequence current mutual inductor cable isolation room, easy to install and maintain.
The same power supply distribution system can limit the short circuit current through the current limiting reactor, stabilize the voltage of the bus bar in a certain value, and can also reduce the requirement for the short circuit strength of the component.
The drawer unit two connector in sufficient quantities (1 units and more than 32 of 1/2, 20 of the unit), which can meet the requirements of the computer interface and the control loop of the contact number.

Three, model: GCL GCK series
The use of the environment: GCK (motor control center), GCL (power distribution center) series of drawer type low-voltage switchgear is suitable for use in AC 50HZ power system rated voltage up to 660V, as the chemical industry, metallurgy, textile, mining and other industrial and mining enterprises of power distribution and control of electric machine.
1 ambient temperature shall not be higher than +40 DEG C; not less than 5 DEG C. And the average temperature in 24h is not higher than +35;
2 clean air, relative humidity at the highest temperature of +40 DEG C, no more than 50, at a lower temperature, allowing a higher relative humidity. For example: +20 90%;
3 no more than 2000m;
4 should be applicable to the following temperature transport and storage process: -25 to +55 C. In a short period of time (not exceeding 24h) up to +70 DEG C, the device shall not be subjected to any non recoverable damage under these limits of humidity, and shall work normally under normal conditions.
Features and use: the power distribution cabinet is a closed interval type structure, which is composed of shaped steel and steel plate bending by assembling body and functional unit connected to the two parts.
