1、 Overview GCK series low-voltage draw out distribution cabinet is a product developed in the early 1990s. Its cost performance ratio is higher than that of similar domestic products, and it has been widely used in China. In order to improve the performance of the product and meet the needs of the rapid development of China’s power system, our company has developed GCK low-voltage withdrawable distribution cabinet according to the market needs. On the basis of maintaining the electrical performance higher than that of similar products, this product has increased the capacity and mechanical strength, and is characterized by advanced structure, beautiful appearance, high protection level, safety, reliability, convenient maintenance, etc; It can be used as a new generation of low-voltage switchgear. 2、 Scope of application and purpose; GCK series low-voltage draw out power distribution cabinet (hereinafter referred to as the device) is an advanced assembled power distribution device, which is suitable for three-phase four wire or three-phase five wire systems with AC 50Hz, rated working voltage of 380v and below as the power conversion, distribution and centralized motor control of the power system distribution equipment in the power center (PC) control center (MCC). It can also form an automatic power supply and distribution control system with a program controller and a microprocessor. This device is an ideal power distribution device for low-voltage power supply systems in power plants, substations, metallurgy, petroleum, chemical, electric power, machinery, textile and other industries, and has been listed as a recommended product for the transformation of the two networks by the state. The device complies with the following standards: IEC60439-1 Low voltage Switchgear and Controlgear Assemblies Part 1: Type Test and Partial Type Test Assemblies GB7251.1 Low voltage Switchgear and Controlgear Assemblies Part 1: Type Test and Partial Type Test Assemblies ZBK3600 Low Voltage Drawout Switchgear 3、Model meaning GGD: G — Low voltage distribution cabinet; G — Fixed installation and wiring; D — Power cabinet; GCK: G — Enclosed switchgear; C – draw out type; K — Control center; GCS: G — Enclosed switchgear; C – draw out type; S — Senyuan electrical system. 4、 Service conditions; 1. The ambient air temperature shall not exceed+40 ℃, and the average temperature within 24h shall not exceed+35 ℃. 2. The lower limit of ambient air temperature is – 5 ℃. 3. For indoor installation and use, the altitude of the place of use shall not exceed 2000m. 4. The air is clean. When the maximum temperature is+40 ℃, its relative humidity shall not exceed 50%; At a lower temperature, a higher relative humidity is allowed. For example, the relative humidity at+20 ℃ is 90%, but due to temperature changes, moderate condensation may occasionally occur. 5. During installation, the inclination to the vertical plane shall not exceed 5 °. 6. The device is suitable for the transportation and storage process at the following temperatures: – 25 ℃ -+55 ℃, which can reach 70 ℃ in a short time (no more than 24h).
